REMOVAL AND INSTALLATION


caution
  • Be sure to remove the clock spring from the column switch and centre the clock spring to prevent the damage of steering wheel sensor.
  • If the centre of the clock spring is not correctly aligned, the steering wheel may not be turned fully or the cable inside the clock spring may be broken, causing the SRS air bag to be inoperative or operated incorrectly.
  • Before removing the steering wheel/air bag module assembly, refer to GROUP 52B - Service Precautions and Air Bag Module Clock Spring .
  • When the steering wheel sensor is replaced or installed, always carry out calibration to make ASC-ECU learn the neutral point (Refer to ).
  • After adjusting the wheel alignment, always carry out calibration of the steering wheel sensor to make ASC-ECU learn the neutral point. (Refer to .)
Pre-removal operation
  • Position the front wheels in a straight ahead direction.

 Post-installation operation
  • Perform steering wheel sensor calibration (Refer to ).

INSTALLATION SERVICE POINT

>>A<< STEERING WHEEL SENSOR INSTALLATION
caution
    Install the steering wheel sensor with its rotating part removed. If the rotating part is rotated 360°, a failure occurs in calibration and ASC system.
Insert the protrusion of the clock spring into the hole of the steering wheel sensor. Securely fit the protrusion of the steering wheel sensor into the groove of the clock spring to install the steering sensor.
note A new steering wheel sensor has a pin for preventing the rotation of (fixing) the steering wheel sensor. After installing the column switch assembly, remove this pin.
