i.

Connect a positive (+) lead from the auxiliary battery to terminal z1-1 (IL+2) and a negative (-) lead to terminal z1-6 (ILL-) 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.
