Replacing Parts After Deployment

REPLACING PARTS AFTER DEPLOYMENT

The following components must be replaced after a collision in which the bag assembly has been deployed:
- Bag assembly
- Steering wheel
- Contact reel
- Crash sensor




Note that the bag assembly has a ten digit identification number which must be quoted when ordering new parts.

Note: It is only necessary to replace the crash sensor if:
- The fault code(s), (does not apply to fault code 1), can be cleared during the repair i e there are no faults left, or
- There is mechanical damage to crash sensor, bracket, mounting bracket or wiring connected to it or
- The floor section next to the crash sensor is damaged in any way.

This does not apply to fault code 1.
If fault code 1 is displayed the crash sensor must be replaced.





Preliminary procedure

Turn ignition switch to off.

Disconnect battery ground lead.

Remove knee bolster to provide access to connectors behind instrument panel.




Remove bag assembly

Remove bag assembly by undoing the two Torx bolts at the rear. (Turn steering wheel slightly to reach the bolts.) Open the connector and lift out bag assembly. Loosen retaining nut in wheel hub, but do not remove it.

Connect battery ground cable

Drive car forward on smooth surface to ensure that front wheels are pointing straight ahead.




Remove steering wheel

Disconnect battery ground cable.

Remove retaining nut in wheel hub.

Remove locking screw in end of plastic ribbon from "parking hole" in wheel (leaving screw in ribbon). Lift off wheel and pull wiring, plastic ribbon and locking screw through opening in wheel.




Remove covers around steering column

Remove turn signal and wiper stalks.

Disconnect wiring harness upper connector behind instrument panel.

Loosen mounting plate and pull out as far as possible to reach retaining screws for contact reel.




Remove contact reel

Remove three retaining screws.




Install new contact reel

Do not forget to reconnect connector behind instrument panel.

Ensure that lead is not pinched.




Install mounting plate, turn signal and wiper stalks.

Install covers around steering column.




Zero new contact reel

Turn contact reel to right end position. Turn approx. three (3) turns to left. The screw hole shall be placed at "six o'clock", as shown in the illustration. Lock with locking screw.

Caution! Do not turn the steering wheel or the contact reel locking screw will shear.




Install new steering wheel

Ensure that front wheels are pointing straight ahead. Carefully pull contact reel lead through hole in steering wheel. Place wheel in position with contact reel locking screw in center hole. Insert and finger tighten retaining nut.

Remove locking screw from locking position (leave attached to ribbon) and place it in its "parking hole" in steering wheel

Check steering wheel position

Reconnect battery ground lead. Drive car forward on smooth surface to ensure that front wheels are pointing straight ahead.

Steering wheel position incorrect:

Disconnect battery ground lead.

Remove locking screw at end of plastic ribbon from its "parking hole" in steering wheel. Remove steering wheel and pull wiring, plastic ribbon and locking screw through opening in wheel.

Zero contact reel.

When steering wheel position is correct:

Tighten wheel retaining nut to 60 Nm (44 ft.lb).




Install knee bolster

Tightening torque: M8 bolt: 20 Nm (15 ft.lb)

Fig. 8 Connecting Test Resistor:




Connect test resistor 998 8695 in place of bag assembly

Connect battery ground cable, then turn ignition switch to position II (ignition ON).

Note: An ohmmeter is permitted to perform the resistance check of special tool 998 8695.

Warning! Under no circumstance may an ohmmeter or other current generating device be used to test resistance of the inflator module, or harness continuity with the inflator module connected.

Fig. 4 Connecting Test Terminal:




Clearing fault codes

Note: Do not turn ignition off between request and clearance of fault code.

Failure of the SRS warning lamp to go out after 10 seconds indicates presence of one or more fault codes due to removal of bag assembly with ignition switched on. Additional fault codes will probably be displayed if assembly was deployed in a collision. This is quite normal.

Proceed as follows:

Repeat code display procedure by grounding test terminal for 2-5 seconds.

Then ground test terminal three times within 1.5 to 5 seconds, for at least 0.25 seconds on each occasion.

Note: Ground lead must be fitted with spade connectors at both ends. Grounding action must be firm and must not be too brief.

Warning lamp will be extinguished for 4 seconds and relight for 3 seconds to confirm clearance of fault code(s). Final extinction of lamp indicates restoration of normal function.




If lamp does not go out

Uncorrected fault is still present. Repeat display procedure, correct fault and repeat clearance procedure.

Fig. 8 Connecting Test Resistor:




Turn off Ignition

Disconnect battery ground lead.

Remove test resistor 998 8695.




Install bag assembly

Rest bottom of assembly on steering wheel (1). Reconnect connector (2). Place assembly in position and retighten

Torx bolts from rear (3). Tightening torque: 8 Nm (5.8 ft.lb).

Note: Tighten right side screw first.

Ensure that lead is clear and is not pinched.

Check operation

Check that steering wheel turns easily and that steering wheel lock operates correctly.

Double check that bag assembly is mounted securely.

Connect battery ground cable, then turn ignition switch to position II (ignition ON).

Connect battery ground lead.

Check it warning lamp goes off.

If not, there is a fault in system. Correct fault(s) as required and clear fault code(s).
