DTC C0200/31 RIGHT FRONT SPEED SENSOR

DTC C0205/32 LEFT FRONT SPEED SENSOR

DTC C1330/35 RIGHT FRONT SPEED SENSOR CIRCUIT

DTC C1331/36 LEFT FRONT SPEED SENSOR CIRCUIT

CIRCUIT DESCRIPTIONThe speed sensor detects wheel speed and transmits the ap-propriate signals to the ECU. These signals are used for controlof the ABS and VSC control systems. Each of the front and rearrotors has 48 serrations.When the rotors rotate, the magnetic field generated by the per-manent magnet in the speed sensor induces an AC voltage.Since the frequency of this AC voltage changes in direct propor-tion to the speed of the rotor, the frequency is used by the ECUto detect the speed of each wheel.


C0200/31C0205/32

When any of the following 1 to 3 is detected :1. Vehicle speed is more than 40 km/h (25 mph), pulses

are not input for 0.01 second.2. After the initial start or restart and when the vehicle

speed has reached 12 km/h (7 mph), the wheel speed of0 km/h (0 mph) is detected.

3. After the initial start or restart and when the vehiclespeed has reached 18 km/h (11 mph), the front wheelspeed of 0 km/h (0 mph) is detected.

the signal waveform.HINT: As the vehicle speed (wheel revolution speed) increases,

a cycle of the waveform becomes shorter and the fluctua-tion in the output voltage becomes greater.

When noise is identified in the waveform on the oscillo-scope, error signals are generated due to the speed sen-sor rotors scratches, looseness or foreign matter depos-ited on it.

DIAGNOSTIC TROUBLE CODE CHARTHINT: Using SST 0984318040, connect the terminal Tc and CG of the DLC3. If malfunction is not found when inspecting parts, inspect the ECU and ground points for poor contact. If a malfunction code is displayed during the DTC check, check the circuit listed for that code. For de-

tails of each code, refer to the See page for respective DTC No. in the DTC chart. When 2 or more DTCs are detected, perform circuit inspection one by one until the problem is identi-

fied.DTC chart of ABS system:

PRECHECK1. DIAGNOSIS SYSTEM(a) Check the warning lights.

(1) Release the parking brake lever.(2) When the ignition switch is turned ON, check that

the ABS warning light, Brake warning light, VSCwarning light, TRC OFF indicator light and SLIP in-dicator light come on for approx. 3 seconds.

HINT: When the parking brake is applied or brake fluid level is

low, the Brake warning light comes on. If the ECU stores DTC, the ABS warning light , VSC warn-

ing light and TRC OFF indicator light come on. If the indicator check result is not normal, proceed to trou-

bleshooting for the light circuit.Trouble Area See page

ABS warning light circuit 05827Brake warning light circuit 05840VSC warning light circuit 05831TRC OFF indicator light circuit 05844SLIP indicator light circuit 05848

(b) Without using handheld tester:Check the DTC.(1) Using SST, connect terminal Tc and CG of the

DLC3.SST 0984318040(2) Turn the ignition switch ON.(3) Read the DTC from the ABS warning light or VSC

warning light on the combination meter.HINT: If no code appears, inspect the diagnostic circuit, ABS

warning light circuit or VSC warning light circuit.Trouble Area See page

As an example, the blinking patterns for the normal codeand codes 11 and 21 are shown on the left.(4) Codes are explained in the code table on page

05766.(5) After completing the check, disconnect terminal Tc

and CG of the DLC3, and turn off the display.If 2 or more DTCs are detected at the same time, the lowestnumbered DTC is displayed first.(c) With using the handheld tester:

Check the DTC.(1) Hook up the handheld tester to the DLC3.(2) Turn the ignition switch ON.(3) Read the DTC by following the prompts on the tes-

ter screen.HINT:Please refer to the handheld tester operators manual for fur-ther details.

(d) Without using handheld tester:Clear the DTCs.(1) Using SST, connect the terminal Tc and CG of the

DLC3.SST 0984318040(2) Turn the ignition switch ON.(3) Clear the DTCs stored in the ECU by depressing the

brake pedal 8 or more times within 5 seconds.(4) Check that the ABS warning light and VSC warning

light indicates the normal code blinking pattern.(5) Remove the SST from the DLC3.SST 0984318040

HINT:Disconnecting the battery cable during repairs will not erase theDTCs in the ECU.(e) With using handheld tester:

Clear the DTCs.(1) Turn the ignition switch ON.(2) Operate the handheld tester to erase the codes.

HINT:Please refer to the handheld tester operators manual for fur-ther details.



2. DATA LISTHINT:According to the DATA LIST displayed on the Handheld tester, you can read the value and status of theswitch, sensor, actuator and so on without parts removal. Reading the DATA LIST as a first step of trouble-shooting is one of the methods to shorten the labor time.(a) Connect the Handheld tester to the DLC3.(b) Turn the ignition switch ON.(c) From the display on the tester, read the DATA LIST.
