Steering wheel member

Important

The optic cables must be handled carefully so as not to distort the signal.

• It is extremely important that the two leads in the connector are not mixed up.

• The cables cannot be spliced.

• The lead must not be bent to form a curve with a radius of less than 25 mm.

• The lead must not be subjected to temperatures greater than 185°F (85°C).

• The lead ends should be kept free from dirt.

• The lead must not be subjected to blows that could cause the transparent plastic to whiten, thereby reducing light intensity. This could cause disruptions in communication.

• The lead should not be stretched across a sharp edge, which would cause increased damping of the signal.


To remove


1. Remove the instrument panel .

2. Remove steering column assembly .

3. Remove the bolts holding the pedal bracket to the steering wheel member.

Undo the pedal wiring connector.


4. Undo the clip which holds the wiring harness.
