i.

Connect a positive (+) lead from the auxiliary battery to terminal 1 (IL+2) and a negative (-) lead to terminal 6 (IL-2) of the steering pad switch assembly connector.


ii.

Check that the steering pad switch assembly illumination illuminates.

OK:

The steering pad switch assembly illumination illuminates.


HINT:

If the result is not as specified, replace the steering pad switch assembly.
