Steering Angle Sensor: Service and Repair




Steering Wheel Module, Steering Wheel And Contact Reel, Replacement

Special tools: 998 8695

NOTE: During work that involves removing the steering wheel and/or contact reel, it is important that the steering wheel be installed such that it is located correctly with regard to the front wheels and that the contact reel is set in the middle position. The contact reel is supplied in the middle position with a locking screw installed. If this locking screw is unfastened the contact reel has to be zeroed again.

CAUTION: The battery must not be connected when the steering wheel module is removed or replaced.

WARNING: Under no circumstances use an ohmmeter or other live measuring instrument to measure the resistance in the steering wheel module. The cabling may not be tested with a connected steering wheel module because this could be deployed.

Adjusting steering wheel position

- The steering wheel position is adjusted in accordance with (B1), (B2), (B4), (B8) and (B9).

Preparations







- Make a note of radio code if anti-theft coded radio installed.
- Turn ignition off.
- Disconnect battery negative lead.

Removing steering wheel module

Connecting special tool 998 8695 to the steering wheel module connector







- Connect special tool 998 8695 to the steering wheel module connector. This is so the car can be driven without the SRS on-board diagnostic (OBD) system storing a diagnostic trouble code (DTC).
