C1113, C1145, C1146 YAW RATE/SIDE/DECEL G SENSOR
Description
The yaw rate/side/decel G sensor detects the yaw rate/side/decel G affecting the vehicle, and transmits the data to the ABS actuator and electric

DTC CONFIRMATION PROCEDURE
1.CHECK SELF-DIAGNOSIS RESULTS
Check the self-diagnosis results.
Is above displayed on the self-diagnosis display?
YES - Proceed to diagnosis procedure. See: C1113.
NO - Inspection End
Diagnosis Procedure
Regarding Wiring Diagram information, See: Brakes and Traction Control/Antilock Brakes / Traction Control Systems/Diagrams/Electrical
Diagrams.
CAUTION:
- Sudden turns (such as spin turns, acceleration turns), drifting, etc. when VDC function is OFF may cause the yaw rate/side/decel G
sensor system to indicate a malfunction. This is not a malfunction if normal operation can be resumed after restarting the engine.
- If vehicle is on turn table at entrance to parking garage, or on other 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 other moving surface, and start engine. Results will return to normal.
1.CONNECTOR INSPECTION
1. Disconnect the ABS actuator and electric unit (control unit) connector and yaw rate/side/decel G sensor connector.
2. Check the terminals for deformation, disconnection, looseness or damage.
Is the inspection result normal?
YES - GO TO 2
NO - Repair or replace as necessary.
2.YAW RATE/SIDE/DECEL G SENSOR HARNESS INSPECTION
Check continuity between the ABS actuator and electric unit (control unit) connector E125 (A) and the yaw rate/side/decel G sensor connector
M108 (B).

Is the inspection result normal?
YES - GO TO 3
NO - Repair or replace as necessary.
3.YAW RATE/SIDE/DECEL G SENSOR INSPECTION
1. Connect the yaw rate/side/decel G sensor connector and ABS actuator and electric unit (control unit) connector.
2. Perform the yaw rate/side/decel G sensor component inspection. See: C1113.
Is the inspection result normal?
YES - Replace the ABS actuator and electric unit (control unit). See: Brakes and Traction Control/Antilock Brakes / Traction Control
Systems/Hydraulic Control Assembly - Antilock Brakes/Service and Repair.
NO - Replace the yaw rate/side/decel G sensor. See: Brakes and Traction Control/Antilock Brakes / Traction Control Systems/Yaw Rate
Sensor/Service and Repair.
Component Inspection
1.CHECK DATA MONITOR
Select "YAW RATE SEN", "SIDE G-SENSOR", "DECEL G-SEN" in "DATA MONITOR" and check yaw rate/side/decel G sensor signal.
Is the inspection result normal?
YES - Inspection End
NO - Go to diagnosis procedure. See: C1113.
Special Repair Requirement
1.ADJUSTMENT OF STEERING ANGLE SENSOR NEUTRAL POSITION
Always perform neutral position adjustment for the steering angle sensor when replacing the ABS actuator and electric unit (control unit). See:
Brakes and Traction Control/Antilock Brakes / Traction Control Systems/Steering Angle Sensor/Testing and Inspection/Description.
- GO TO 2
2.CALIBRATION OF DECEL G SENSOR
Always perform calibration of decel G sensor when replacing the ABS actuator and electric unit (control unit). See: Brakes and Traction
Control/Antilock Brakes / Traction Control Systems/Yaw Rate Sensor/Testing and Inspection/Description.
