- Ignition in position I so that the steering wheel lock is disengaged.
Adjust the steering column to a comfortable and accessible working position.
- Undo screws (2 x Torx 30) in countersunk holes on back of steering wheel. The screws should not be removed, they should remain in the countersunk holes on the steering wheel.
Turn the steering wheel (90° in both directions) to access the screws.
If, due to damaged Torx slots or threads, the screws cannot be removed normally as above, they must be drilled out.

Technician Safety Information
- Under no circumstances use an ohmmeter or other live measuring instrument to take readings on a disconnected non-deployed airbag module. This could deploy the airbag.
CAUTION: When removing a non-deployed steering wheel module (when replacing the steering wheel or contact reel for example) the module should be placed with its metal side (rear) downwards somewhere where it will not be handled carelessly (in the luggage compartment for example).
Connecting Special Tool 998 8695
- Install special tool 998 8695 to SRS ignition cable igniter connector
This is so the car can be driven without the SRS on-board diagnostic (OBD) system posting a DTC.
If the ignition is switched on when neither steering wheel module nor special tool are connected, an open circuit diagnostic trouble code (DTC) will be posted. (Diagnostic trouble codes (DTC)s must be cleared.)
Undo But Do Not Remove The Steering Wheel Center Bolt
- Undo the steering wheel center bolt (with an 18 mm socket wrench), but do not remove it
It should be possible to unscrew the bolt by hand in the next operation,
Center Front Wheels
Align the front wheels to point straight ahead.
- Connect battery negative lead.
- Drive the car on a level surface so that the front wheels point straight ahead.
NOTE: Work that requires the removal of the steering wheel/contact reel should be carried out with the front wheels pointing straight ahead.
WARNING: Do not drive the car further than necessary to align the front wheels. The steering wheel is not properly tightened and the steering wheel module has been removed.
