Removal and Installation

REMOVAL





1. Remove center console.
2. Disconnect G sensor harness connector.
3. Remove G sensor mounting bolts. Then remove G sensor from vehicle.

CAUTION:
^ Do not drop or strike G sensor, because it has little endurance to impact.

Calibration of Decel G Sensor (AWD Models)

NOTE:
After removing/installing or replacing yaw rate/side/decel G sensor, ABS actuator and electric unit (control unit), suspension components, or after adjusting wheel alignment, make sure to calibration of decel G sensor before running vehicle.

CAUTION:
To calibrate decel G sensor, make sure to use CONSULT-III.) (Adjustment can not be done without CONSULT-III.)

1. Stop vehicle with front wheels in straight-ahead position.

CAUTION:
^ The work should be done at a horizontal place when vehicle is in the unloaded vehicle condition.
^ Keep all tires inflated to correct pressures. Adjust the tire pressure to the specified pressure value.

2. Touch "WORK SUPPORT" and "DECEL G-SEN CALIBRATION" on CONSULT-III screen in this order.
3. Touch "START".

CAUTION:
Set vehicle as shown in the display.
