Preparations
- make a note of the anti-theft radio code.
- ignition off.
- disconnect the battery negative lead.
Warning! During assembly, the ignition must be in position II. Then reconnect the battery negative lead, according to Conclusion. Ensure that nobody is in the car when the battery is being connected.
Ignition in position I
Warning! The battery must not be connected when the SRS ignition cable connector is being removed or installed.
Ignition switch to position I so that the steering wheel lock is disengaged.
Slacken off steering wheel screws
Slacken off the two screws (Torx 30) on the reverse of the steering wheel. The screws must not be removed, but remain in the counter sunk holes in the steering wheel. Turn the steering wheel to access the screws.
Removing airbag steering wheel module
Disconnect the connector and lift off the steering wheel module.
Warning! 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!
Warning! The steering wheel module must never be taken apart, repaired or moved to another vehicle. For handling of a replaced module, see Handling replaced SRS airbags / seat belt tensioners Handling Replaced SRS Airbags/Seat Belt Tensioners.
Positioning the steering wheel module
Caution! If a non-deployed steering wheel module is removed temporarily, it must be placed with the metal side (rear) downwards in a protected place.
Connecting special tool
Connect special tool 998 8695 TEST DEVICE 998 8695 Test Device to steering wheel module connector.
This makes it possible to drive the car without the SRS on-board diagnostic (OBD) system registering a diagnostic trouble code (DTC).
Hint: If the ignition is switched on when neither the steering wheel module nor special tool are connected, a diagnostic trouble code (DTC) will be stored indicating an open-circuit in the cable. Any diagnostic trouble codes (DTC) must be erased.
Slacken off center screw
Slacken off the screw but leave it in place. The screw should be loose enough that it can be unscrewed by hand.
Reconnect the battery negative lead
Align the front wheels
- Drive the car straight forwards or backwards on a level surface so that the wheels point straight ahead.
Caution! It is always important to point the wheels straight ahead when carrying out work that requires the removal of the steering wheel and/or contact reel.
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.
Disconnect the battery negative lead
Ignition off.

Reassembly
Resetting contact reel
If the locking screw is not in the lock position as illustrated, the contact reel must be reset. For resetting see Resetting SRS contact reel Reset Procedure.
Note! A new contact reel is zeroed at the factory and supplied with the locking screw installed. Zeroed means that the steering wheel can be turned to full lock in either direction without damaging the contact reel.
Installing contact reel / SRS
Install:
- the contact reel / SRS.
- 3 contact reel / SRS screws. Tighten the contact reel screw to 2.5 Nm and ensure that no cable is pinched.
- the connector.
- apply contact grease on the slide rail for better contact.
Install switch, steering wheel covers and steering wheel
Install:
- 2 Torx 20 screws on the switch.
- 3 Torx 20 screws in steering wheel cover.
Caution! Do not turn the steering wheel when the contact reel is locked as the contact reel pin will shear off.
Allow cable and tie straps to pass through the hole in the steering wheel, then install the steering wheel without turning it.
Caution! The steering wheel must be installed in the correct position in relation to front wheel alignment.
If the steering wheel was not installed straight, it must not be turned on the steering column. Carefully remove the steering wheel and try again.
Installing center screw
Caution! Finger tighten the screw. Do not use a tool.
Unlocking the contact reel
Remove the screw from lock position (B) and install it in the parking position (A). Do not detach the screw from the plastic strip.
The contact reel is now unlocked (unsecured) and the steering wheel can be turned.

Adjusting the front wheels
Drive the car straight forwards or backwards on a level surface so that the wheels point straight ahead.
Carefully turn the steering wheel. Check that it can be turned to full lock in each direction.
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.
If the steering wheel is not straight:
See, Disconnect the battery negative lead, Resetting contact reel.
If the steering wheel will not turn to full lock:
See, Disconnect the battery negative lead, Resetting contact reel.
