HINT:
If the result is not as specified, replace the steering pad switch assembly.
(b) Check the illumination.
(1) 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.
(2) 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.
