coil spring (contact roller)

 To remove

 Warning

Read the Safety and handling directions before starting work. See “Safety and handling directions”

 Warning

If the work calls for the removal of the coil spring (contact roller) it is important to ensure that it is in its middle position when the steering wheel is replaced.


1.Ignition switch in the OFF position.
2.Set the steering wheel in the position at which the road wheels are straight ahead.
3.Remove the airbag from the steering wheel, 2 screws and plugs.
4.Lift out the steering-wheel airbag and undo the connections on the back of it.

Important

Since the steering wheel separates very suddenly from the taper there is a risk that the coil spring and leads may get caught on the steering wheel and suffer damage.
5.Undo the steering wheel centre nut but leave the nut on the outer threads and pull off the steering wheel to that point. Then remove the nut and carefully lift off the steering wheel.
6.Slip the leads of the coil spring out and lift the steering wheel clear.
7.Remove the upper and lower steering column covers, 3 screws.
8.Undo the 2 screws securing the coil spring.
9.Detach the leads from the hook and unplug connectors.
10.Lift out the coil spring.
 To fit


1.Put the coil spring in place.
2.Tighten the screws securing the coil spring, 2 pcs. Plug in the connector.

 Warning

Make sure the cables are not pinched when fitting the bottom cover.

3.Refit the upper and lower steering column covers, 3 screws.
4.Adjust the centre position of the coil spring, as follows:

4.a.Check that the road wheels are set straight ahead.
4.b.Turn the coil spring clockwise until you feel stiff resistance.
4.c.Turn the coil spring back two complete turns, plus the distance that remains until the electric leads are standing straight up.

Note

If a new coil spring is being fitted, no adjustment to the central position is needed. The coil comes ready-set to the central position, being held there by a transport arrester.
5.Check that the leads connected to the coil spring are not twisted.

6.Fit the steering wheel and tighten the steering wheel centre nut.

Tightening torque: 38 Nm (28.1 lbf ft)

Plug in the connector for the horn and also for the audio system, if fitted.

7.Plug in the airbag's electrical connector at the rear.
8.Fit the airbag in the steering wheel, 2 screws and plugs.
9.Switch the ignition on and check the SRS system and control module with the diagnostic tool as follows:

Connect the diagnostic tool to the diagnostic socket under the dashboard. Clear any diagnostic trouble codes that may be present.

Turn the ignition off and on again. Wait at least 10 seconds with the ignition on.

Check whether a diagnostic trouble code is shown:

If a diagnostic trouble code is shown:

Carry out the relevant fault diagnosis as described under the respective DTC.

If no diagnostic trouble code is shown:
