■ 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.
- 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.
 1.CHECK CONNECTOR
- Turn the ignition switch OFF.
- Disconnect ABS actuator and electric unit (control unit) connector.
- Disconnect yaw rate/side/decel G sensor connector.
- 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
- Turn the ignition switch ON.
■ CAUTION ■ Never start the engine.
- Check the voltage between yaw rate/side/decel G sensor harness connector and ground.

 5.REPLACE YAW RATE/SIDE/DECEL G SENSOR
- Replace yaw rate/side/decel G sensor. Refer to Exploded View (GT-R certified NISSAN dealer).
- Erase ABS actuator and electric unit (control unit) self-diagnosis results.
- Turn the ignition switch OFF.
- Turn the ignition switch ON.
■ CAUTION ■ Never start the engine.
- Perform ABS actuator and electric unit (control unit) self-diagnosis.
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
