■ CAUTION ■

- Sudden turns (such as spin turns, accelerated turns), drifting, etc., when VDC function is off (VDC OFF indicator “ON”) may cause yaw rate/side/decel G sensor system to indicate a malfunction. However, this is not a malfunction, if normal operation can be resumed after restarting engine. Then erase memory of self-diagnosis for “ABS” with CONSULT-III.
- If vehicle is on turn-table at entrance to parking garage, or on another moving surface, VDC OFF indicator lamp may illuminate and CONSULT-III self-diagnosis may indicate yaw rate sensor system malfunction. However, in this case there is no malfunction in yaw rate sensor system. Take vehicle off of turn-table or the other moving surface, and start the engine. Results will return to normal. Then erase memory of self-diagnosis for “ABS” with CONSULT-III.

1.CHECK CONNECTOR

1. Turn the ignition switch OFF.
2. Disconnect ABS actuator and electric unit (control unit) harness connector.
3. Disconnect yaw rate/side/decel G sensor harness connector.
4. Check terminal for deformation, disconnection, looseness, etc.

Is the inspection result normal?
YES>>GO TO 2.
NO>>Repair or replace error-detected parts.
2.CHECK YAW RATE/SIDE/DECEL G SENSOR POWER SUPPLY CIRCUIT

1. Turn the ignition switch ON.
   ■ CAUTION ■
   Never start the engine.
2. Check the voltage between yaw rate/side/decel G sensor harness connector and ground.

   Yaw rate/side/decel G sensor | — | Voltage
   Connector | Terminal
   B36 | 3 | Ground | Battery voltage

3. Turn the ignition switch OFF.
4. Check the voltage between yaw rate/side/decel G sensor harness connector and ground.

   Yaw rate/side/decel G sensor | — | Voltage
   Connector | Terminal
   B36 | 3 | Ground | Approx. 0 V

Is the inspection result normal?
YES>>GO TO 3.
NO>>Repair or replace error-detected parts.
3.CHECK YAW RATE/SIDE/DECEL G SENSOR GROUND CIRCUIT
Check the continuity between yaw rate/side/decel G sensor harness connector and ground.

Yaw rate/side/decel G sensor | — | Continuity
Connector | Terminal
B36 | 5 | Ground | Existed

Is the inspection result normal?
YES>>GO TO 4.
NO>>Repair or replace error-detected parts.
4.CHECK YAW RATE/SIDE/DECEL G SENSOR HARNESS
Check the continuity between yaw rate/side/decel G sensor harness connector and ABS actuator and electric unit (control unit) harness connector.

ABS actuator and electric unit (control unit) | Yaw rate/side/decel G sensor | Continuity
Connector | Terminal | Connector | Terminal
E41 | 26 | B36 | 1 | Existed
11 | 2
39 | 3
27 | 5

Is the inspection result normal?
YES>>GO TO 5.
NO>>Repair or replace error-detected parts. Refer to Precautions for Harness Repair.
5.REPLACE YAW RATE/SIDE/DECEL G SENSOR

1. Replace yaw rate/side/decel G sensor. Refer to Exploded View (GT-R certified NISSAN dealer).
2. Erase self-diagnosis results for “ABS” with CONSULT-III.
3. Turn the ignition switch OFF.
4. Turn the ignition switch ON.
   ■ CAUTION ■
   Never start the engine.
5. Perform self-diagnosis for “ABS” with CONSULT-III.

Is DTC “C1113”, “C1145” or “C1146” detected?
YES>>Replace ABS actuator and electric unit (control unit). Refer to Exploded View (GT-R certified NISSAN dealer).
NO>>INSPECTION END
