Disassembly

Special tools: 998 8695







CDA1. Preparation
Make a note of any radio code.
Ignition off.
Disconnect the battery negative lead.


WARNING! When assembling turn the ignition key to position II, then connect the battery negative lead. Make sure that nobody is inside the car when connecting the battery.


CDA2. Turning The Ignition Key To Position I






WARNING! Make sure the battery is disconnected before disconnecting or connecting the ignition wire.


Turn the ignition key to position I to unlock the steering lock.



CDA3. Loosen The Steering Wheel Screws






Loosen the two screws (Torx 30) at the back of the steering wheel. Do not remove the screws, leave them in the recesses of the steering wheel. Turn the steering wheel to get to the screws.



CDA4. Removal of steering wheel airbag module






Disconnect the connector and lift the steering wheel air bag module out.


WARNING! Never use an ohmmeter or any other charged measuring instrument on a disconnected, unreleased airbag module. There is a risk that the module could be released! Also,do not disassemble or repair the steering wheel airbag module or install it in another vehicle.



CDA5. Positioning the steering wheel airbag module






CAUTION! When the unreleased steering wheel airbag module is removed, position the module metal-side down (i.e. the back) in a place where it will be protected from careless handling.


CDA6. Connecting the special tools






Connect special tool 998 8695 to the steering wheel airbag module connector. This enables the car to be driven without the SRS diagnosis system registering a diagnostic trouble code.


HINT: If the ignition is switched on when neither the steering wheel airbag module nor the special tool is connected, a diagnostic trouble code registering an open circuit will appear. Erase any diagnostic trouble code.


CDA7. Loosening the retaining screw in the centre of the steering wheel






Loosen the screw but do not remove it. The screw should be loose enough to turn with your fingers.


CDA8. Connecting the battery negative lead






CDA9. Aligning the front wheels






Drive the car slowly in a straight line forwards or backwards on a level surface so that the wheels are directly in line with the car lengthways.


CAUTION! It is imperative that the front wheels are directly in line with the car lengthways if the steering wheel and/or the contact reel need to be removed to do work.


WARNING! Do not drive the car further than necessary when aligning the front wheels. The steering wheel is not secured and the steering wheel air bag module is removed.



CDA10. Disconnecting the battery negative lead






Ignition off.



CDA11. Removal of the special tools






Remove the special tool 998 8695.



CDA12. Securing the contact reel

Remove:
the steering column cover and selector according to CDA14
3 screws on the contact reel/SRS
the connector from the contact reel.

Assembly






CDA16. Resetting the contact reel to zero
If the locking screw is not in the lock position as shown in the figure, reset the contact reel to zero. For resetting to zero Clockspring Assembly / Spiral Cable

NOTE: The new contact reel is reset to zero when locking screws are positioned in the lock position. Resetting to zero ensures that all electrical functions on the steering column operate and damage to the contact reel does not occur.



CDA17. Installation of contact reel/SRS






Install:
The contact reel/SRS
3 screws on the contact reel/SRS. Tighten the screws on the contact reel to 2.5 Nm (1.9 ft-lb). Make sure that no wires are trapped

Install:
2 screws, Torx 20, on each selector
3 screws, Torx 20, on the steering column cover.


CAUTION! Do not turn the steering wheel when the contact reel is locked or the pin on the contact reel will break.


Put the wires and the plastic tape through the opening in the steering wheel and then install the steering wheel without turning it.


CAUTION! When installing the steering wheel put it in the correct position in relation to the direction the wheels are facing.


If the steering wheel is not in the correct position, do not turn it when it is on the steering column. Carefully remove the steering wheel and try again.



CDA19. Installing the retaining screw in the centre of the steering wheel.






CAUTION! Tighten the screw finger tight only. Do not use any tools.
