SUPPLEMENTAL RESTRAINT SYSTEM (SRS)

The Accord Sedan/Coupe (V6) SRS includes a dr iver 's airbag located in the steering wheel hub, a passenger's airbag located in the dashboard above the glove box, and side airbags ('00-01 models) located in the front seat-backs. Information necessary to safely service the SRS is included in the '98-01 Accord Sedan/Coupe (L4) Service Manual, P/N 61S8008. Items marked wi th an asterisk ( * ) on the contents page include or are located near SRS components. Servicing, disassembling or replacing these items wi l l require special precautions and tools, and should therefore be done by and authorized Honda dealer.

• To avoid rendering the SRS inoperative, which could lead to personal injury or death in the event of a severe frontal col l ision, all SRS service work must be performed by an authorized Honda dealer.

• Improper service procedures, including incorrect removal and installation of the SRS, could lead to personal injury caused by unintentional deployment of the frontal airbags (and/or side airbags on some '00-01 models).

• Do not bump the SRS unit, Otherwise, the system may fail in case of a coll ision, or the airbags may deploy when the ignit ion switch is ON (II).

• SRS electrical wir ing harnesses are indicated wi th yel low color coding. Related components are located in the steering column, front console, dashboard, dashboard lower panel, in the dashboard above the glove box, in the front seats ('00-01 models) and around the f loor ('00-01 models). Do not use electrical test equipment on these circuits.

the life of the system. *3 : Always use Genuine Honda Power Steering Fluid. Using any other type of power steering f luid or automatic

transmission f luid can cause increased wear and poor steering in cold weather.

NOTE: Lubricate all hinges, latches, and locks once a year. In corrosive areas, more frequent lubrication is necessary. We recommend Honda White Lithium Grease.

Valve Guide Replacement

Special Tools Required • Valve Guide Driver, 5.5 m m 07742-0010100 • Valve Guide Reamer, 5.5 mm 07HAH-PJ7010B

1. As illustrated below, use a commercial ly available air-impact valve guide driver (A) modif ied to fit the diameter of the valve guides. In most cases, the same procedure can be done using the special tool and a conventional hammer.

/ 5.3 m m (0.21 in.)

_ 87 m m (3.43 in.]

57 m m (2.24 in.)

10.8 m m (0.42 in.)

2. Select the proper replacement guides and chill them in the freezer section of a refrigerator for about an hour.

3. Use a hot plate or oven to evenly heat the cylinder head to 300°F (150°C). Monitor the temperature wi th a cooking thermometer. Do not get the head hotter than 300°F (150°C); Excessive heat may loosen the valve seats.

4. Working f rom the camshaft side, use the driver and an air hammer to drive the guide about 2 m m (0.1 in.) towards the combustion chamber. This wi l l knock off some of the carbon and make removal easier. Hold the air hammer directly in line wi th the valve guide to prevent damaging the driver. Wear safety goggles or a face shield.

5. Turn the head over and drive the guide out toward the camshaft side of head.

6. If a valve guide won' t move, dril l it out wi th a 8 mm (5/16 in.) bit, then try again. Drill guides only in extreme cases; you could damage the cylinder head if the guide breaks.

7. Remove the new guide(s) f rom the freezer, one at a t ime, as you need them.

9. Coat both the reamer and the valve guide wi th cutt ing oi l .

10. Rotate the reamer clockwise the full length of the valve guide bore.

11. Continue to rotate the reamer clockwise whi le removing it f rom the bore.

12. Thoroughly wash the guide in detergent and water to remove any cutting residue.

13. Check the clearance wi th a valve (see page 6-44). Verify that the valve slides in the intake and exhaust valve guides wi thout exerting pressure.

Valve Seat Reconditioning

If the valve guides are worn (see page 6-44), replace them (see page 6-45)before cutting the valve seats.

1. Renew the valve seats in the cylinder head using a valve seat cutter.

- 1 Carefully cut a 45° seat, removing only enough material to ensure a smooth and concentric seat.

- 2 Bevel the upper edge of the seat wi th the 30° cutter and the lower edge of the seat with the 60° cutter. Check the width of the seat and adjust accordingly.

- 3 Make one more very light pass wi th the 45° cutter to remove any possible burrs caused by the other cutters.

Valve Seat Width: Standard (New): 1.25-1.55 mm

(0.049 0.061 in.) Service Limit: 2.00 mm (0.079 in.)

After resurfacing the seat, inspect it for even valve seating: Apply Prussian Blue compound (A) to the valve face. Insert the valve in its original location in the head, then lift it and snap it closed against the seat several t imes.

3. The actual valve seating surface (B), as shown by the blue compound, should be centered on the seat.

• If it is too high (closer to the valve stem), you must make a second cut wi th the 60° cutter to move it down, then one more cut wi th the 45° cutter to restore seat width.

• If it is too low (closer to the valve edge), you must make a second cut wi th the 30° cutter to move it up, then one more cut wi th the 45° cutter to restore seat width.

NOTE: The final cut should always be made wi th the 45° cutter.

Main Bearing Clearance Inspection

1. To check main bearing-to-journal oil clearance, remove the main caps and bearing halves.

2. Clean each main journal and bearing half w i th a clean shop towel .

3. Place one strip of plastigage across each main journal.

NOTE: If the engine is still in the car when you bolt the main cap down to check the clearance, the weight of the crankshaft and drive plate wi l l f latten the plastigage further than just the torque on the cap bolt and give you an incorrect reading. For an accurate reading, support the crank wi th a jack under the counterweights, and check only 1 bearing at a t ime.

4. Reinstall the bearings and caps, then torque the bolts (see page 7-24). Do not rotate the crankshaft.

5. Remove the caps and bearing halves, and measure the widest part of the plastigage.

Main Bearing-to-Journal Oil Clearance: Standard (New): 0.020 0.044 mm

(0.0008 0.0017 in.) Service Limit: 0.050 mm (0.0020 in.)

6. If the plastigage measures too wide or too narrow, (remove the engine if it's still in the car), remove the crankshaft, and remove the upper half of the bearing. Install a new, complete bearing with the same color code, and recheck the clearance. Do not f i le, shim, or scrape the bearings or the caps to adjust clearance.

7. If the plastigage shows the clearance is still incorrect, try the next larger or smaller bearing (the color listed above or below that one), and check again. If the proper clearance cannot be obtained by using the appropriate larger or smaller bearings, replace the crankshaft and start over.

System Descriptions

Electronic Control System

The functions of the fuel and emission control systems are managed by the Powertrain Control Module (PCM).

Fail-safe Function When an abnormality occurs in a signal f rom a sensor, the PCM ignores that signal and assumes a pre-programmed value for that sensor that allows the engine to continue to run.

Back-up Function When an abnormality occurs in the PCM, the injectors are controlled by a back-up circuit independent of the system in order to permit minimal driving.

Self-diagnosis When an abnormality occurs in the signal f rom a sensor, the PCM supplies ground for the Malfunction Indicator Lamp (MIL) and stores the Diagnostic Trouble Code (DTC) in erasable memory. When the ignit ion is first turned on, the PCM supplies ground for the MIL for 2 seconds to check the MIL bulb condit ion.

Two Driving Cycle Detection Method To prevent false indications, the " two driving cycle detection method" is used for some self-diagnostic functions. When an abnormality occurs, the PCM stores it in its memory. When the same abnormality recurs after the ignition switch is turned OFF and ON (II) again, the PCM informs the driver by turning on the MIL.

Fuel and Emissions Systems

System Descriptions (cont'd)

PCM Data

You can retrieve data f rom the PCM by connecting the OBD II scan tool or the Honda PGM Tester to the Data Link Connector (DLC). The items listed in the table below conform to SAE recommended practice. The Honda PGM Tester also reads data beyond that recommended by SAE. Understanding this data may help you f ind the causes of intermittent problems.

NOTE: • The "operat ing values" listed are approximate and may vary depending on the environment and the individual

vehicle. • Unless noted otherwise, "a t idle speed" means idl ing wi th the engine completely warmed up, transmission in Park

or neutral and the A/C and all accessories turned off.

Data Description Operating Value Freeze Data Diagnostic Trouble Code (DTC)

If the PCM detects a problem, it wi l l store it as a code consisting of one letter and four numbers. Depending on the problem, an SAE-defined code (POxxx) or a Honda-defined code (P1xxx) wi l l be output to the tester.

If no problem is detected, there is no output.

YES

Engine Speed The PCM computes engine speed f rom the signals sent f rom the Crankshaft Position (CKP) sensor. This data is used for determining the t ime and amount of fuel injection.

Nearly the same as tachometer indication At idle speed: 680 + 50 rpm

YES

Vehicle Speed The PCM converts pulse signals f rom the countershaft speed sensor into speed data.

Nearly the same as speedometer indication

YES

Manifold Absolute Pressure (MAP)

The absolute pressure caused in the intake manifold by engine load and speed.

With engine stopped: Nearly the same as atmospheric pressure At idle speed: 2 0 - 3 4 kPa (150 260 mmHg, 6 - 1 0 in.Hg)

YES

Engine Coolant Temperature (ECT)

The ECT sensor converts coolant temperature into voltage and signals the PCM. The sensor is a thermistor whose internal resistance changes wi th coolant temperature. The PCM uses the voltage signals f rom the ECT sensor to determine the amount of injected fuel.

With cold engine: Same as ambient temperature and I AT With engine warmed up: approx. 176-212°F ( 8 0 -100°C)

YES

Primary Heated Oxygen Sensor (Primary H02S) (Sensor 1), Secondary Heated Oxygen Sensor (Secondary H02 S) (Sensor 2)

The H02S detects the oxygen content in the exhaust gas and sends voltage signals to the PCM. Based on these signals, the PCM controls the air/ fuel ratio. When the oxygen content is high (that is, when the ratio is leaner than the stoichiometric ratio), the voltage signal is lower. When the oxygen content is low (that is, when the ratio is richer than the stoichiometric ratio), the voltage signal is higher.

0 .0-1 .25 V At idle speed: about 0 .1 -0 .9 V

NO

11-8

Page 255: 1998-2001 Honda Accord v-6 b7xa

Data Description Operating Valve Freeze Data Fuel System Fuel system status is indicated as " o p e n " or

"c losed". Closed: Based on the H02S output, the PCM determines the air/fuel ratio and controls the amount of injected fuel. Open: ignoring H02S output, the PCM refers to signals f rom the Throttle Position (TP), Manifold Absolute Pressure (MAP), Intake Air Temperature (IAT), Barometic Pressure (BAR0) and Engine Coolant Temperature (ECT) sensors to control the amount of injected fuel.

At idle speed: closed YES

Short Term Fuel Tr im

The air/fuel ratio correction coefficient for correcting the amount of injected fuel when Fuel System Status is "c losed" . When the ratio is leaner than the stoichiometric ratio, the PCM increases short tern fuel t r im gradually, and the amount of injected fuel increases. The air/fuel ratio gradually gets richer, causing a lower oxygen content in the exhaust gas. Consequently, the short term fuel t r im is lowered, and the PCM reduces the amount of injected fuel. This cycle keeps the air/fuel ratio close to the stoichiometric ratio when in closed loop status.

0.73—1.47 YES

Long Term Fuel Tr im

Long term fuel t r im is computed f rom short term fuel t r im and indicates changes occuring in the fuel supply system over a long period. If long term fuel t r im is higher than 1.00, the amount of injected fuel must be increased. If it is lower than 1.00, the amount of injected fuel must be reduced.

0.81—1.19 YES

Intake Air Temperature (IAT)

The IAT sensor converts intake air temperature into voltage and signals the PCM. When intake air temperature is low, the internal resistance of the sensor increases, and the voltage signal is higher.

With cold engine: Same as ambient temperature and ECT

YES

Throttle Position

Based on the accelerator pedal position, the opening angle of the throttle valve is indicated.

Fuel and Emissions Systems

System Descriptions (cont'd)

PGM-FI S y s t e m

The Programmed Fuel Injection (PGM-FI) system is a sequential mult iport fuel injection system.

Air Conditioning (A/C) Compressor Clutch Relay When the PCM receives a demand for cooling f rom the A/C system, it delays the compressor f rom being energized, and enriches the mixture to assure smooth transit ion to the A/C mode.

Air Conditioning (A/C) Switch The A/C switch signals the PCM whenever there is a demand for cool ing.

Alternator Control The alternator signals the Powertrain Control Module (PCM) during charging. The PCM then controls the voltage generated at the alternator assording to the electrical load determined by the Electrical Load Detector (ELD) and driving mode. This reduces engine load to improve fuel economy.

Barometric Pressure (BARO) Sensor The Baro sensor is inside the PCM. It converts atmospheric pressure into a voltage signal that modif ies the basic duration of the fuel injection discharge.

Crankshaft Position (CKP) Sensor The CKP sensor determines t iming for fuel injection of each cylinder and also detects engine speed. The PCM detects misf ir ing by using the CKP sensor to monitor f luctuations in crankshaft speed. It wi l l then set DTCs depending on how much misf ir ing occurs.

Engine Coolant Temperature (ECT) Sensor The ECT sensor is a temperature dependent resistor (thermistor). The resistor of the thermistor decreases as the Engine Coolant temperature increases.

T H E R M I S T O R

Ignition Timing Control The PCM contains the memory for basic ignition t iming at various engine speeds and manifold absolute pressure. It also adjusts the t iming according to engine coolant temperature.

Injector Timing and Duration The PCM contains the memory for basic discharge duration at various engine speeds and manifold pressures. The basic discharge duration, after being read out f rom the memory, is further modif ied by signals sent f rom various sensors to obtain the final discharge duration. By monitor ing long term fuel t r im, the PCM detects long term malfunctions in the fuel system, and wi l l set a Diagnostic Trouble Code (DTC).

11-22

Page 269: 1998-2001 Honda Accord v-6 b7xa

Intake Air Temperature (IAT) Sensor The IAT sensor is a temperature dependent resistor (thermistor). The resistance of the thermistor decreases as the intake air temperature increases.

THERMISTOR

Malfunction Indicator Lamp (MIL) Indication (In relation to Readiness Codes)('01 model) The vehicle has certain "readiness codes" that are part of the on-board diagnostics for the emissions systems. If the vehicle's battery has been disconnected or gone dead, these codes are erased. In some states, part of the emissions testing is to make sure these codes are set If all of them are not set, the test cannot be completed.

To check if the readiness codes are set, turn the ignition switch ON (II), but do not start the engine. The MIL will come on for 15 — 20 seconds. If it then goes off, the readiness codes are set. If it blinks several times, the readiness codes are not set completely. To reset each code, drive the vehicle or run the engine as described in the procedures to set them. Refer to the '98-01 Accord Service Manual (see page 11-42).

Manifold Absolute Pressure (MAP) Sensor The MAP sensor converts manifold absolute pressure into electrical signals to the PCM.

SENSOR UNIT

3 b r

Primary Heated Oxygen sensor (Primary H02S) The primary H02S detects the oxygen content in the exhaust gas and sends signals to the PCM which varies the duration of fuel injection accordingly. To stabilize its output, the sensor has an internal heater. The primary H02S is installed in the exhaust manifold. By controlling the air fuel ratio with primary H02S and secondary H02S, the deterioration of the primary H02S can be evaluated by its feedback period. When the feedback period exceeds a certain value during stable driving conditions, the sensor is considered deteriorated and the PCM sets a DTC.

S E N S O R T E R M I N A L S

H E A T E R H E A T E R T E R M I N A L S

Secondary Heated Oxygen sensor (Secondary H02S) The secondary H02S detects the oxygen content in the exhaust gas downstream of the Three Way Catalytic Converter (TWO and sends signals to the PCM which varies the duration of fuel injection accordingly. To stabilize its output, the sensor has an internal heater. The secondary H02S is installed in the TWC.

Idle Control System

When the engine is cold, the A/C compressor is on, the transmission is in gear, the brake pedal is depressed, the P/S load is high, or the alternator is charging, the PCM controls current to the I AC valve to maintain the correct idle speed. Refer to the System Diagram to see the functional layout of the system.

Brake Pedal Position Switch The brake pedal position switch signals the PCM when the brake pedal is pressed.

Idle Air Control (IAC) Valve To maintain the proper idle speed, the IAC valve changes the amount of air bypassing the throttle body in response to an electrical signal f rom the PCM.

F r o m A IR T o I N T A K E C L E A N E R M A N I F O L D

Power Steering Pressure (PSP) Switch The PSP switch signals the PCM when the power steering load is high.

Starter (Ignition) Switch The starter switch signals the PCM when the engine is cranking.

Fuel Supply System

Fuel Cut-off Control During deceleration wi th the throttle valve closed, current to the fuel injectors is cut off to improve fuel economy at speeds over 1,100 rpm. Fuel cut-off action also occurs when engine speed exceeds 6,600 rpm, regardless of the position of the throttle valve, to protect the engine f rom over-revving. When the vehicle is stopping, then PCM cuts the fuel at engine speed over 5,000 rpm.

Fuel Pump Control When the ignition is turned on, the PCM grounds the PGM-FI main relay which feeds current to the fuel pump for 2 seconds to pressurize the fuel system. With the engine running, the PCM grounds the PGM-FI main relay and feeds current to the fuel pump. When the engine is not running and the ignition is on, the PCM cuts ground to the PGM-FI main relay which cuts current to the fuel pump.

PGM-FI Main Relay The PGM-FI relay contains 2 separate relays. One is energized whenever the ignition is on which supplies battery voltage to the PCM, power to the fuel injectors, and power for the second relay. The second relay is energized to supply power to the fuel pump for 2 seconds when the ignition is switched ON (II), and when the engine is running.

Intake Air System

Refer to the System Diagram to see the functional layout of the system.

Intake Air Bypass Control System (Fuel Air (FIA) Control System) When the engine is running, the Intake Air Bypass control valve sends air to the fuel injectors.

EVAP Canister The EVAP canister temporarily stores fuel vapor from the fuel tank until it can be purged back into the engine and burned (Refer to System Diagram to see the functional layout of the system).

EVAP Canister Purge Valve When the engine coolant temperature is above 167°F (75°C), the PCM controls the EVAP canister purge valve which provides vacuum to the EVAP canister.

Fuel Tank Pressure (FTP) Sensor The FTP sensor converts fuel tank absolute pressure into an electrical input to the PCM.

Idle Control System Diagram

The idle speed of the engine is controlled by the IAC (Idle Air Control) valve:

• After the engine starts, the IAC valve opens for a certain amount of t ime. The amount of air is increased to raise the idle speed by about 150^-300 rpm.

• When the engine coolant temperature is low, the IAC valve is opened to obtain the proper fast idle speed. The amount of bypassed air is thus controlled in relation to engine coolant temperature.

Exhaust Gas Recirculation (EGR) System Diagram

The EGR system reduces oxides of nitrogen (NOx) emissions by recirculating exhaust gas through the EGR valve and the intake manifold into the combust ion chambers. The PCM memory includes the ideal EGR valve position for varying operating condit ions. The EGR valve position sensor detects the amount of EGR valve posit ion and sends it to the PCM. The PCM then compares it wi th the ideal lift in its memory (based on signals sent f rom other sensors). If there is any difference between the two, the PCM cuts current to the EGR valve.

Evaporative Emission (EVAP) Control Diagram

The EVAP controls minimize the amount of fuel vapor escaping to the atmosphere. Vapor f rom the fuel tank is temporari ly stored in the EVAP canister until it can be purged f rom the canister into the engine and burned.

• The EVAP canister is purged by drawing fresh air through it and into a port on the intake manifold. The purging vacuum is controlled by the EVAP canister purge valve, which is open whenever engine coolant temperature is above 147°F (64°C).

• When vapor pressure in the fuel tank is higher than the set value of the EVAP two way valve, the valve opens and regulates the f low of fuel vapor to the EVAP control canister.

• During refueling, the fuel tank vapor control valve opens wi th the pressure in the fuel tank, and feeds the fuel vapor to the EVAP canister.

How to Check for DTCs with the PGM Tester/Scan Tool

When the PCM senses an abnormali ty in the input or output systems, the (H indicator l ight in the gauge assembly wi l l blink. When the 16P Data Link Connector (DLC) (located next to the driver's side kick panel) is connected to the OBD II Scan Tool or Honda PGM Tester as shown, the scan tool or tester wi l l indicate the Diagnostic Trouble Code (DTC) when the ignition switch is turned ON(II).

HONDA PGM T E S T E R or OBD II S C A N T O O L

If the E indicator l ight or the MIL has been reported on, or if a driveabil ity problem is suspected, fo l low this procedure:

1. Connect the OBD II Scan Tool (conforming to SAE J1978) or Honda PGM Tester to the 16P DLC. (See the OBD II Scan Tool or Honda PGM Tester user's manual for specific instructions. If you are using the Honda PGM Tester, make sure it is set to the SAE DTC type.)

2. Turn the ignit ion switch ON (II), and observe the DTC on the screen.

3. Record all fuel and emission DTCs, A/T DTCs, and freeze data.

4. If there is a fuel and emissions DTC, first check the fuel and emissions system as indicated by the DTC (except for DTC P0700). DTC P0700 means there is one or more A/T DTC, and no problems were detected in the fuel and emissions circuit of the PCM.

5. Get the anti-theft code for the radio, then wri te down the radio station presets.

6. Reset the memory wi th the PGM Tester or by removing the BACK UP fuse in the passenger's under-dash fuse/ relay box for more than 10 seconds.

7. Drive the vehicle for several minuites in the freeze data conditions or at speeds over 30mph (50 km/hr), and then recheck for DTCs. If the A/T DTC returns, go to the DTC Troubleshooting Index on page 14-7. If the DTC does not return, there was an intermittent problem wi th in the circuit. Make sure all pins and terminals in the circuit are tight, and then go to step 8.

8. Enter the radio code, reset the radio preset stations, and set the clock.

Symptom Troubleshooting Index

These symptoms DO NOT trigger Diagnostic Trouble Codes (DTCs) or cause the E indicator light to blink. If the Malfunction Indicator Lamp (MIL) was reported ON or the S indicator l ight has been blinking, check for DTCs. But if the vehicle has one of the symptoms in the fo l lowing chart, check the probable causes(s) for it, in the sequence listed, until you f ind the problem.

Symptom Probable cause(s) Notes

When you turn the ignit ion switch ON (II), the B indicator light comes on and stays on or never comes on at all

A problem in the B indicator l ight circuit

Check the B indicator light circuit (see page 14-93).

Shift lever cannot be moved f rom B position whi le you're pushing on the brake pedal

A problem in shift lock system of interlock system

Check interlock system — shift lock system circuit (see page 14-96).

Ignition key cannot be moved f rom ACC (1) posit ion to LOCK (0) posit ion whi le you're pushing the ignit ion key wi th the shift lever in I B position

A problem in key interlock system of interlock system

Check interlock system — key interlock system circuit (see page 14-99).

14-8

Page 359: 1998-2001 Honda Accord v-6 b7xa

Symptom Probable cause(s) Notes

Engine runs, but vehicle does not move in any gear

1. Low ATF level 2. Shift cable broken or out of

adjustment 3. Joint in shift cable and

transmission or body worn 4. ATF pump worn or binding 5. Regulator valve stuck or

spring worn 6. ATF strainer clogged 7. Mainshaft worn or

damaged 8. Final gears worn or

damaged 9. Transmission-to-engine

assembly error 10. Axle disengaged

• Check ATF level and check ATF cooler lines for leakage and loose connections. If necessary, f lush ATF cooler lines.

• Check for a loose shift cable on the shift lever and the transmission control shaft.

• Improper al ignment of ATF pump and torque converter housing may cause ATF pump seizure. The symptoms are mostly an rpm-related ticking noise or a high pitched squeak.

• Measure line pressure. • If the strainer is clogged, f ind the damaged

components that caused debris. • Inspect the differential pinion shaft for wear under the

pinion gears. If the differential pinion shaft is worn , overhaul the differential assembly, replace the ATF strainer, thoroughly clean the transmission, and flush the torque converter, cooler, and lines.

• Be careful not to damage the torque converter housing when replacing the main ball bearing. You may also damage the ATF pump when you torque down the main valve body. This wi l l result in ATF pump seizure if not detected. Use the proper tools.

• Install the main seal f lush wi th the torque converter housing. If you push it into the torque converter housing until it bottoms out, it wi l l block the f luid return passage and result in damage.

Vehicle moves in \2\ and ID, but not in H , IE, or HI position

1. 1st accumulator defective 2. 1st gears worn or damaged 3. 1st clutch defective

• Inspect 1st clutch pressure. • Inspect the secondary shaft and 1st/2nd clutch

assembly for wear and damage. • Inspect the clutch piston and O-rings. Check the

Automatic Transmission

System Description

General Operation The automatic transmission is a combinat ion of a 3-element torque converter and triple-shaft electronically controlled automatic transmission which provides 4 speeds forward and 1 reverse. The entire unit is positioned in line wi th the engine.

Torque Converter, Gears, and Clutches The torque converter consists of a pump, turbine, and stator assembly in a single unit. They are connected to the engine crankshaft so they turn together as a unit as the engine turns. Around the outside of the torque converter is a ring gear which meshes wi th the starter pinion when the engine is being started. The entire torque converter assembly serves as a f lywheel t ransmit t ing power to the transmission mainshaft. The transmission has three parallel shafts: the mainshaft, the countershaft, and the secondary shaft. The mainshaft is in line wi th the engine crankshaft. The mainshaft includes the 3rd and 4th clutches, and gears for 3rd, 4th, reverse, and idler (reverse gear is integral wi th the 4th gear). The countershaft includes the final drive, 1st, 3rd, 4th, reverse, 2nd, park, and idler gears (the final drive gear is integral wi th the countershaft). The secondary shaft includes the 1st and 2nd clutches, and gears for 1st, 2nd and idler. The countershaft 4th gear and the countershaft reverse gear can be locked to the countershaft at its center, providing 4th gear or reverse, depending wi th which way the selector moved. The gears on the mainshaft and the secondary shaft are in constant mesh wi th those on the countershaft. When certain combinations of gears in the transmission are engaged by the clutches, power is transmitted f rom the mainshaft and the secondary shaft to the countershaft to provide H, 33, HI, LE and El positions.

Electronic Control The electronic control system consists of the Powertrain Control Module (PCM), sensors, and six solenoid valves. Shift ing and lock-up are electronically control led for comfortable driving under all conditions. The PCM is located below the dashboard, under the f ront lower panel behind the center console.

Hydraulic Control The valve bodies include the main valve body, the regulator valve body, the servo body, and the accumulator body. They are bolted to the torque converter housing. The main valve body contains the manual valve, the modulator valve, the shift valve C, the shift valve D, the shift valve E, the servo control valve, the torque converter check valve, the reverse CPC valve, the lock-up shift valve, the relief valve, the cooler check valve, and the ATF pump gears. The regulator valve body contains the regulator valve, the lock-up t iming valve, and the lock-up control valve. The servo body contains the servo valve, the shift valve A, the shift valve B, the CPC valves A and B, and 3rd and 4th accumulators. The accumulator body contains the 1st and 2nd accumulators and lubrication check valve. Fluid f rom the regulator passes through the manual valve to the various control valves. The 1st, 3rd, and 4th clutches receive f lu id f rom their respective feed pipes, and the 2nd clutch receives f luid f rom the internal hydraulic circuit.

Shift Control Mechanism The PCM controls shift solenoid valves A, B, and C, and A/T clutch pressure control solenoid valves A and B whi le receiving input signal f rom various sensors located throughout the vehicle. The shift solenoid valves shift the positions of the shift valves to switch the port leading hydraulic pressure to the clutch. The A/T clutch pressure control solenoid valves A and B control the CPC valves A and B to shift smoothly between lower gear and higher gear. This pressurizes a line to one of the clutches, engaging the clutch and its corresponding gear.

Lock-up Mechanism In H position (3rd and 4th), and S3 posit ion (3rd), pressurized f luid is drained f rom the back of the torque converter through a f luid passage, causing the lock-up piston to be held against the torque converter cover. As this takes place, the mainshaft rotates at the same speed as the engine crankshaft. Together wi th hydraulic control, the PCM optimizes the t iming of the lock-up mechanism. When the torque converter clutch solenoid valve activates, modulator pressure changes to switch lock-up on and off. The lock-up control valve and the lock-up t iming valve control the range of lock-up according to A/T clutch pressure control solenoid valves A and B. The torque converter clutch solenoid valve is mounted on the torque converter housing, and A/T clutch pressure control solenoid valves A and B are mounted on the transmission housing. They are all control led by the PCM.

Automatic Transmission

System Description (cont'd)

Clutches

The four-speed automatic transmission uses hydraulically-actuated clutches to engage or disengage the transmission gears. When hydraulic pressure is introduced into the clutch drum, the clutch piston moves. This presses the friction discs and steel plates together, locking them so they don't slip. Power is then transmitted through the engaged clutch pack to its hub-mounted gear. Likewise, when the hydraulic pressure is bled from the clutch pack, the piston releases the friction discs and the steel plates, and they are free to slide past each other. This allows the gear to spin independently on its shaft, transmitting no power.

1st Clutch The 1st clutch engages/disengages 1st gear, and is located at the middle of the secondary shaft. The 1st clutch is joined back-to-back to the 2nd clutch. The 1st clutch is supplied hydraulic pressure by its ATF feed pipe within the secondary shaft.

2nd Clutch The 2nd clutch engages/disengages 2nd gear, and is located at the middle of the secondary shaft. The 2nd clutch is joined back-to-back to the 1st clutch. The 2nd clutch is supplied hydraulic pressure through the secondary shaft by a circuit connected to the internal hydraulic circuit.

3rd Clutch The 3rd clutch engages/disengages 3rd gear, and is located at the middle of the mainshaft. The 3rd clutch is joined back-to-back to the 4th clutch. The 3rd clutch is supplied hydraulic pressure by its ATF feed pipe within the mainshaft.

4th Clutch The 4th clutch engages/disengages 4th gear, as well as reverse gear, and is located at the middle of the mainshaft. The 4th clutch is joined back-to-back to the 3rd clutch. The 4th clutch is supplied hydraulic pressure by its ATF feed pipe within the mainshaft.

Shift Control Shifting is related to engine torque through the solenoid valves, which are controlled by the PCM. The PCM instantly determines which gear should be selected by various signals sent f rom sensors, and actuates the shift solenoid valves A, B, and C to control shifting. Also, a Grade Logic Control System to controls shift ing in E and B positions whi le the vehicle is ascending or descending a slope, or reducing speed. The combination of driving signals to shift solenoid valves A, B, and C is shown in the table below.

Lock-up Control The torque converter clutch solenoid valve controls modulator pressure to switch the lock-up shift valve and lock-up ON and OFF. The PCM controls the torque converter clutch solenoid valve and the A/T clutch pressure control solenoid valves A and B. When the torque converter clutch solenoid valve is turned ON, the condit ion of lock-up starts. The A/T clutch pressure control solenoid valves A and B regulate A/T clutch pressure control solenoid pressure, and apply the pressure to the lock-up control valve and the lock-up t iming valve. The lock-up control mechanism operates in 3rd, and 4th gear in B and in 3rd gear in B positions.

Ascending Control

When the PCM determines that the vehicle is cl imbing a hill in B and E positions, the system extends the engagement area of 2nd gear and 3rd gear to prevent the transmission f rom frequently shift ing between 2nd and 3rd gears, and between 3rd and 4th gears, so the vehicle can run smooth and have more power when needed.

NOTE: • Shift schedules stored in the PCM between 2nd and 3rd gears, and between 3rd and 4th gears, enable the PCM's

fuzzy logic to automatically select the most suitable gear according to the magnitude of a gradient. • Fuzzy logic is a form of artificial intelligence that lets computers respond to changing conditions much like a human

mind would.

Vehicle speed

Descending Control

When the PCM determines that the vehicle is going down a hill in B and B positions, the shift-up speed f rom 3rd to 4th gear and f rom 2nd to 3rd (when the thrott le is closed) becomes faster than the set speed for flat road driving to widen the 3rd gear and 2nd gear dr iving areas. This, in combination wi th engine braking f rom the deceleration lock-up, achieves smooth driving when the vehicle is descending. There are two descending modes wi th different 3rd gear driving areas and 2nd gear driving areas according to the magnitude of a gradient stored in the PCM. When the vehicle is in 4th gear, and you are decelerating when you are applying the brakes on a steep hil l, the transmission wi l l downshift to 3rd gear. When you accelerate, the transmission wi l l then return to higher gear.

Deceleration Control

When the vehicle goes around a corner and needs to decelerate first and then accelerate, the PCM sets the data for deceleration control to reduce the number of t imes the transmission shifts. When the vehicle is decelerating f rom speeds above 27 mph (43 km/h), the PCM shifts the transmission f rom 4th to 2nd earlier than normal to cope wi th upcoming acceleration.

Regulator Valve The regulator valve maintains constant hydraulic pressure f rom the ATF pump to the hydraulic control system, whi le also furnishing f lu id to the lubricating system and torque converter. Fluid f rom the ATF pump f lows through B and B\ Fluid entering f rom B f lows through the valve orifice to the A cavity. This pressure of the A cavity pushes the regulator valve to the right side, and this movement of the regulator valve uncovers the f luid port to the torque converter and the relief valve. The f luid f lows out to the torque converter and the relief valve, and the regulator valve moves to the left side. According to the level of the hydraulic pressure through B, the position of the regulator valve changes, and the amount of f luid f rom B' through torque converter changes. This operation is continued, maintaining the line pressure.

Increases in hydraulic pressure according to torque are performed by the regulator valve using stator torque reaction. The stator shaft is splined to the stator in the torque converter, and its arm end contacts the regulator spring cap. When the vehicle is accelerating or cl imbing (Torque Converter Range), stator torque reaction acts on the stator shaft, and the stator arm pushes the regulator spring cap in the direction of the arrow in proportion to the reaction. The stator reaction spring compresses, and the regulator valve moves to increase the line pressure which is regulated by the regulator valve. The line pressure reaches its max imum when the stator torque reaction reaches its max imum.

Hydraulic Flow

Distribution of Hydraulic Pressure As the engine turns, the ATF pump starts to operate. Automatic transmission f luid (ATF) is drawn through the ATF strainer (filter) and discharged into the hydraulic circuit. Then, ATF f lowing f rom the ATF pump becomes line pressure that's regulated by the regulator valve. Torque converter pressure f rom the regulator valve enters the torque converter through the lock-up shift valve and it is discharged f rom the torque converter. The torque converter check valve prevents torque converter pressure f rom rising. The PCM controls the shift solenoid valves ON and OFF, and the shift solenoid valves control shift solenoid pressure to the shift valves. Apply ing shift solenoid pressure to the shift valves moves the position of the shift valve, and switches the port of hydraulic pressure. The PCM also controls A/T clutch pressure control solenoid valves A and B. The A/T clutch pressure control solenoid valves regulated the A/T clutch pressure control solenoid pressure and apply the A/T clutch pressure control solenoid pressure to CPC valves A and B. When shifting between upper gear and lower gear, the clutch is engaged by pressure f rom the CPC pressure mode. The PCM controls one of the shift solenoid valves to move the position of the shift valve. This movement switches the port of the CPC and line pressure. Line pressure is then applied to the clutch, and the CPC pressure is intercepted. Engaging the clutch wi th line pressure happens when shifting is completed.

Hydraulic pressure at the parts is as fol lows:

Lock-up System

In H position (3rd and 4th), and S position (3rd), pressurized f luid is drained f rom the back of the torque converter through a f luid passage, causing the lock-up piston to be held against the torque converter cover. As this takes place, the mainshaft rotates at the same speed as the engine crankshaft. Together wi th hydraulic control, the PCM optimizes the t iming of the lock-up mechanism. When the torque converter clutch solenoid valve activates, modulator pressure changes to switch lock-up ON and OFF. The lock-up control valve and the lock-up t iming valve control the range of lock-up according to A/T clutch pressure control solenoid valves A and B. The torque converter clutch solenoid valve is mounted on the torque converter housing, and A/T clutch pressure control solenoid valves A and B are mounted on the transmission housing. They are controlled by the PCM.

General Operation

1. Operation (clutch on) Wi th the lock-up clutch on, f luid in the chamber between the torque converter cover and the lock-up piston is drained off, and the converter f luid exerts pressure through the piston against the torque converter cover. As a result, the converter turbine is locked to the converter cover. The effect is to bypass the converter, placing the vehicle in direct drive.

M A I N S H A F T

2. Operation (clutch off) With the lock-up clutch off, f lu id f lows in the reverse of CLUTCH ON. As a result, the lock-up piston moves away f rom the converter cover, and torque converter lock-up is released.

No Lock-up

The torque converter clutch solenoid valve is turned OFF by the PCM. The lock-up shift valve receives LC pressure (LA) on the left side, and modulator pressure (6) on the right side. The lock-up shift valve is in the right side to uncover the port leading torque converter pressure (92) to the left side of the torque converter. Torque converter pressure (92) becomes torque converter pressure (94), and enters into the left side of the torque converter to disengage the lock-up clutch. The lock-up clutch is OFF.

Partial Lock-up

As the speed of the vehicle reaches the prescribed value, the torque converter clutch solenoid valve is turned ON by the PCM to release LC pressure (LA) in the left side of the lock-up shift valve. The lock-up shift valve is moved to the left side to switch the port leading torque converter pressure to the left side and right side of the torque converter. Torque converter pressure (92) f lows to the right side of the torque converter to engage the lock-up clutch. The PCM also controls A/T clutch pressure control solenoid valves A and B, and LS A or LS B pressure is applied to the lock-up control valve and the lock-up t iming valve. The posit ion of the lock-up control valve depends on torque converter pressure and LS A or LS B pressure. When LS A or LS B pressure (58) is lower, torque converter pressure (91) f rom the lock-up t iming valve is lower. The lock-up clutch is engaged partially. LS A or LS B (58) increases, and the lock-up t iming valve is moved to the left side to uncover the port leading torque converter pressure to high. The lock-up clutch is then engaged securely. Under this condit ion, the lock-up clutch is engaged by pressure f rom the right side of the torque converter; this condit ion is partial lock-up.

The LS A or LS B pressure (58) is applied to the lock-up control valve and the lock-up t iming valve, and moves them to the left side. Under this condit ion, torque converter back pressure is released fully, causing the lock-up clutch to be ful ly engaged.

Valve Body Repair

NOTE: This repair is only necessary if one or more of the valves in a valve body do not slide smoothly in their bores. Use this procedure to free the valves.

1. Soak a sheet of # 600 abrasive paper in ATF for about 30 minutes.

2. Carefully tap the valve body so the sticking valve drops out of its bore. It may be necessary to use a small screwdriver to pry the valve free. Be careful not to scratch the bore wi th the screwdriver.

3. Inspect the valve for any scuff marks. Use the ATF-soaked # 600 paper to polish off any burrs that are on the valve, then wash the valve in solvent and dry it wi th compressed air.

4. Roll up half a sheet of ATF-soaked # 600 paper and insert it in the valve bore of the sticking valve. Twist the paper slightly, so that it unrolls and fits the bore t ightly, then polish the bore by twist ing the paper as you push it in and out.

NOTE: The valve body is a luminum and doesn't require much polishing to remove any burrs.

5. Remove the # 600 paper. Thoroughly wash the entire valve body in solvent, then dry it wi th compressed air.

6. Coat the valve wi th ATF, then drop it into its bore. It should drop to the bottom of the bore under its own weight. If not, repeat step 4, then retest. If the valve still sticks, replace the valve body.

7. Remove the valve, and thoroughly clean it and the valve body with solvent. Dry all parts wi th compressed air, then reassemble using ATF as a lubricant.

General Troubleshooting Information

ABS/TCS Indicators

• If the system is OK, the ABS indicator goes off once after turning the ignition switch ON(II) wi thout starting the engine, and then comes on again and goes off several seconds later after starting the engine. This occurs because the ABS/TCS control unit is turned on by the IG2 power source.

• The TCS or ABS indicator comes on when the ABS/ TCS control unit detects a problem in the system. However, even though the system is operating properly, the TCS or ABS indicator wil l come on, under the fol lowing conditions:

• For ABS or TCS Indicator: - Only drive wheels rotate - One drive wheel is stuck - The vehicle goes into a spin. - The ABS continues to operate for a long t ime. - The vehicle is subjected to an electrical signal

disturbance. • For TCS Indicator:

- The TCS operated when the front brake pad temperature rises excessively.

- The TCS switch is OFF. - One or more of these components are faulty:

Heated oxygen sensor, Manifold absolute pressure sensor, Crankshaft position sensor, Engine coolant temperature sensor, Throttle position sensor, Top dead center sensor, Top dead center sensor 2, Intake air temperature sensor, Exhaust gas recirculation, Barometric pressure sensor, Idle air control valve, VTEC pressure switch, Knock sensor, Fuel supply system, Automatic transaxle, Misfire detection system of the PGM-FI system.

To determine the actual cause of the problem, question the customer about the problem, taking these conditions into consideration:

• When a problem is detected and the ABS or TCS indicator comes on, there are cases when the indicator stays on until the ignition switch is turned OFF, and cases when the indicator goes off automatically when the system returns to normal. For ABS DTCs 61 and 62, the indicator goes off automatically when the system returns to normal. For all other codes, the indicator stays on until the ignition switch is turned OFF.

• For ABS DTCs 12, 14, 16, 18, 21, 22, 23, 24, 51 , 52 and 53, the ABS indicator goes off when the vehicle is driven again and the system is OK after the ignit ion switch is turned f rom OFF to ON (II). However, if the DTC is cleared, the CPU resets and the indicator goes off right after the engine is started if the system is OK.

• The ABS is not operational when the ABS indicator is ON; the TCS is not operational when the TCS indicator is ON.

• When the ABS and TCS indicators are both ON, troubleshoot the ABS first.

• When the TCS indicator and MIL are both ON, troubleshoot the PGM-FI system first.

Diagnostic Trouble Code (DTC)

• The memory can hold any number of DTCs. However, when the same DTC is detected more than once, the more recent DTC is wri t ten over the earlier one . Therefore, when the same problem is detected repeatedly, it is memorized as a single DTC.

• The DTCs are indicated in ascending number order, not in the order they occur.

• The DTCs are memorized in the EEPROM (non­volatile memory). Therefore, the memorized DTCs cannot be canceled by disconnecting the battery. Perform the specified procedures to clear the DTCs.

Self-diagnosis

• Self-diagnosis can be classified into 2 categories: - Initial diagnosis: Performed right after the engine

starts and until the ABS or TCS indicator goes off. - Regular diagnosis: Performed right after the initial

diagnosis until the ignition switch is turned OFF. • When a problem is detected by self-diagnosis/the

ABS/TCS control unit shifts to fail-safe mode.

Kickback

The pump motor operates when the ABS is funct ioning, and the f luid in the reservoir is forced out to the master cylinder, causing kickback at the brake pedal.

Pump Motor

• The pump motor operates when the ABS is functioning.

• The ABS/TCS control unit checks the pump motor operation during initial diagnosis when the vehicle is started. You may hear the motor operate at this t ime, but it is normal.

Brake Fluid Replacement/Air Bleeding

Brake fluid replacement and air bleeding procedures are identical to the procedures used on vehicles not equipped with ABS/TCS. To ease bleeding, start wi th the front wheels.

How to Troubleshoot ABS and TCS DTCs

The troubleshooting f lowchart procedures assume that the cause of the problem is still present and the ABS and/or TCS indicator is still on. Following the f lowchart when the ABS and/or TCS indicator does not come on can result in incorrect diagnosis. The connector i l lustrations show the female terminal connectors wi th a single outline and the male terminal connectors wi th a double outl ine.

1. Question the customer about the condit ions when the problem occured, and try to reproduce the same condit ions for troubleshooting. Find out when the ABS and/or TCS indicator came on, such as during ABS control , after ABS control, when vehicle speed was at a certain speed, etc.

2. When the ABS or TCS indicator does not come on during the test drive, but t roubleshoot ing is performed based on the DTC, check for loose connectors, poor contact of the terminals, etc. before you start troubleshooting.

3. After troubleshoot ing, clear the DTCs, and test-drive the vehicle. Make sure the ABS and TCS indicators do not come on.

How to Retrieve ABS or TCS DTCs

Using the Honda PGM Tester:

1. With the ignit ion switch OFF, connect the Honda PGM Tester (A) to the 16P Data Link Connector (DLC) (B) behind the driver's side kick panel.

2. Turn the ignition switch ON (II), and fo l low the prompts on the Honda PGM Tester to display the DTC(s) on the screen. After determining the DTC, refer to the DTC Troubleshooting Index.

NOTE: See the Honda PGM Tester user's manual for specific instructions.

Shorting the Service Check Signal Circuit with the Honda PGM Tester:

1. With the ignition switch OFF, connect the Honda PGM Tester (A) to the 16P Data Link Connector (DLC) (B) behind the driver's side kick panel.

2. Short the SCS circuit to body ground using the Honda PGM Tester.

3. Turn the ignition switch ON i brake pedal.

4. The blinking frequency indicates the DTC.

NOTE: If the DTC is not memorized, the ABS or TCS indicator wi l l go off for 3.6 seconds, and then come back on.

The system wi l l not indicate the DTC unless these condit ions are met: • The TCS switch is not pushed. • The brake pedal is not pressed. • The ignition switch is turned ON (II). • The engine is stopped. • The SCS circuit is shorted to body ground before

the ignition switch is turned ON (II).

ABS Self-Diagnosis

• The ABS/TCS control unit is equipped with a main CPU and a sub CPU. Each CPU checks the other for problems.

• The CPUs check the circuit of the system.

9 Self-diagnosis can be classified into 2 categories; - Initial diagnosis: Performed right after the engine starts and until the ABS or TCS indicator goes off. - Regular diagnosis: Performed right after the initial diagnosis until the ignition switch is turned OFF.

• When a problem is detected by self-diagnosis, the ABS/TCS control unit shifts to fail-safe mode.

Regular operation Operation in normal condi t ion OFF OFF

Fail-safe mode-S1 The ABS/TCS control unit turns the system off (ABS fail-safe relay off) when the

control unit detects a prob lem.

ON ON

Fail-safe mode-AO If the ABS/TCS control unit detects a mal funct ion whi le the ABS or TCS is

operat ing, it w i l l tu rn off the mal funct ioning component , and cont inue to

modulate the rest of the ABS system until complet ing the ABS or TCS operat ion.

At that t ime, the entire system wi l l be turned off unti l the problem goes away.

ON ON

Fail-safe mode-LO The ABS/TCS control unit stores a DTC in back-up memory when it detects a

prob lem. If a prob lem is detected when the igni t ion switch is turned ON (II), the

ABS/TCS control unit wi l l turn the system off. If the problem goes away, the

ABS/TCS control unit wi l l turn the system on again.

ON ON

Fail-safe mode-BO The ABS/TCS control unit wi l l turn the system off if ignit ion voltage drops, and

wi l l turn it on again when ignit ion vol tage returns to normal.

System Description (cont'd)

Wheel S e n s o r

The wheel s e n s o r s are the magnetic contactless type. A s the gear pulser teeth rotate past the wheel sensor 's magnetic coil, A C current is generated. The A C frequency changes in accordance with the whee l s p e e d . The A B S / T C S control unit detects the wheel sensor signal f requency and thereby detects the wheel speed.

Battery

Battery Test

A battery can explode if you do not fo l low the proper procedure, causing serious injury to anyone nearby. Follow all procedures carefully and keep sparks and open flames away f rom the battery.

Use either a JCI or Bear ARBST tester, and fo l low the manufacturer's procedures. If you don't have one of these computerized tester, fo l low this conventional test procedure:

1. Be sure the temperature of the electrolyte is between 70°F (21°C) and 100°F (38°C).

2. Inspect the battery case for cracks or leaks.

• If the case is damaged, replace the battery. • • If the case looks OK, go to step 3.

3. Check the indicator EYE.

• If the EYE indicates the battery is charged, go to step 4.

• If the EYE indicates a low charge, go to step 7.

4. Apply a 300 amp load for 15 seconds to remove the surface charge.

5. Wait 15 seconds, then apply a test load of 280 amps for 15 seconds.

6. Record battery voltage.

• If voltage is above 9.6 volts, the battery is OK. • • If voltage is below 9.6 volts, go to step 7.

7. Charge the battery on High (40 amps) until the EYE shows the battery is charged, plus an additional 30 minutes. If the battery charge is very low, it may be necessary to bypass the charger's polarity protection circuitry.

• If the EYE indicates the battery is charged wi th in 3 hours, the battery is OK.B

• If the EYE indicates the battery is not charged wi th in 3 hours, replace the battery. •

Power Relay Test

Identify the relay, then do the test listed for i t

NOTE: Refer to the '98-01 Accord Service Manual for the relay input test except that it is mentioned in this manual (see page 22-52)

Relay Test TCS relay Normally-open type A

Normally-open type A:

Check for continuity between the terminals.

• There should be continuity between the No. 1 and No. 2 terminals when power and ground are connected to the No. 3 and No. 4 terminals.

• There should be no continuity between the No. 1 and No. 2 terminals when power is disconnected. - TCS relay ('01 model)
