PRECAUTIONPRECAUTIONS

Precautions for Trouble Diagnosis INFOID:0000000005170205

CAUTION:• Never apply 7.0 V or more to the measurement terminal.• Use a tester with open terminal voltage of 7.0 V or less.• Turn the ignition switch OFF and disconnect the battery cable from the negative terminal when

checking the harness.

Precautions for Harness Repair INFOID:0000000005170206

• Solder the repaired area and wrap tape around the soldered area.NOTE:A fray of twisted lines must be within 110 mm (4.33 in).

• Bypass connection is never allowed at the repaired area.NOTE:Bypass connection may cause CAN communication and ITS com-munication error. The spliced wire becomes separated and thecharacteristics of twisted line are lost.

• Replace the applicable harness as an assembly if error is detected on the shield lines of CAN communica-tion line and ITS communication line.

[CAN FUNDAMENTAL]CAN COMMUNICATION SYSTEM

< SYSTEM DESCRIPTION >

SYSTEM DESCRIPTIONCAN COMMUNICATION SYSTEM

System Description INFOID:0000000005170207

• CAN communication is a multiplex communication system. This enables the system to transmit and receivelarge quantities of data at high speed by connecting control units with two communication lines (CAN-H andCAN-L).

• Control units on the CAN network transmit signals using the CAN communication control circuit. Theyreceive only necessary signals from other control units to operate various functions.

• CAN communication lines adopt twisted-pair line style (two lines twisted) for noise immunity.

System Diagram INFOID:0000000005170208

Each control unit passes an electric current to the termination circuits when transmitting CAN communicationsignal. The termination circuits produce an electrical potential difference between CAN-H and CAN-L. CANcommunication system transmits and receives CAN communication signals by the potential difference.

SKIB8887E

Component Description

Main line CAN communication line between splices

Branch line CAN communication line between splice and a control unit

Splice A point connecting a branch line with a main line

Termination circuit Refer to LAN-9, "CAN Communication Control Circuit".

TROUBLE DIAGNOSIS

Condition of Error Detection INFOID:0000000005528867

DTC of CAN communication is indicated on SELF-DIAG RESULTS on CONSULT-III if a CAN communicationsignal is not transmitted or received between units for 2 seconds or more.NOTE:DTCs of CAN communication are as follows:• U0101• U0140• U0164• U1000• U1001

CAN COMMUNICATION SYSTEM ERROR• CAN communication line open (CAN-H, CAN-L, or both)• CAN communication line short (ground, between CAN communication lines, other harnesses)• Error of CAN communication control circuit of the unit connected to CAN communication line

WHEN DTC OF CAN COMMUNICATION IS INDICATED EVEN THOUGH CAN COMMUNICATIONSYSTEM IS NORMAL• Removal/installation of parts: Error may be detected when removing and installing CAN communication unit

and related parts while turning the ignition switch ON. (A DTC except for CAN communication may bedetected.)

• Fuse blown out (removed): CAN communication of the unit may cease.• Voltage drop: Error may be detected if voltage drops due to discharged battery when turning the ignition

switch ON (Depending on the control unit which carries out CAN communication).• Error may be detected if the power supply circuit of the control unit, which carries out CAN communication,

malfunctions (Depending on the control unit which carries out CAN communication).• Error may be detected if reprogramming is not completed normally.CAUTION:CAN communication system is normal if DTC of CAN communication is indicated on SELF-DIAGRESULTS of CONSULT-III under the above conditions. Erase the memory of the self-diagnosis of eachunit.

Symptom When Error Occurs in CAN Communication System INFOID:0000000005528868

In CAN communication system, multiple units mutually transmit and receive signals. Each unit cannot transmitand receive signals if any error occurs on CAN communication line. Under this condition, multiple control unitsrelated to the root cause malfunction or go into fail-safe mode.

< BASIC INSPECTION >• Indication of the combination meter is important to detect the root cause because it is the most obvious to

the customer, and it performs CAN communication with many units.

INSPECTION OF VEHICLE CONDITIONCheck whether the symptom is reproduced or not.NOTE:Do not turn the ignition switch OFF or disconnect the battery cable while reproducing the error. The error maytemporarily correct itself, making it difficult to determine the root cause.

CHECK OF CAN SYSTEM TYPE (HOW TO USE CAN SYSTEM TYPE SPECIFICATION CHART)Determine CAN system type based on vehicle equipment.NOTE:• This chart is used if CONSULT-III does not automatically recognize CAN system type.• There are two styles for CAN system type specification charts. Depending on the number of available sys-

tem types, either style A or style B may be used.

[CAN]PRECAUTIONS

< PRECAUTION >

PRECAUTIONPRECAUTIONS

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER" INFOID:0000000005170222

The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used alongwith a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certaintypes of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRSsystem uses the seat belt switches to determine the front air bag deployment, and may only deploy one frontair bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.Information necessary to service the system safely is included in the “SRS AIR BAG” and “SEAT BELT” of thisService Manual.WARNING:• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in

the event of a collision which would result in air bag inflation, all maintenance must be performed byan authorized NISSAN/INFINITI dealer.

• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personalinjury caused by unintentional activation of the system. For removal of Spiral Cable and Air BagModule, see the “SRS AIR BAG”.

• Do not use electrical test equipment on any circuit related to the SRS unless instructed to in thisService Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or har-ness connectors.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERSWARNING:• When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the

ignition ON or engine running, DO NOT use air or electric power tools or strike near the sensor(s)with a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possiblycausing serious injury.

• When using air or electric power tools or hammers, always switch the ignition OFF, disconnect thebattery, and wait at least 3 minutes before performing any service.

Precautions for Trouble Diagnosis INFOID:0000000005170223

CAUTION:• Never apply 7.0 V or more to the measurement terminal.• Use a tester with open terminal voltage of 7.0 V or less.• Turn the ignition switch OFF and disconnect the battery cable from the negative terminal when

checking the harness.

Precautions for Harness Repair INFOID:0000000005170224

• Solder the repaired area and wrap tape around the soldered area.NOTE:A fray of twisted lines must be within 110 mm (4.33 in).
