Below 2.5 Ω | If the result is not as specified, replace the steering pad switch assembly.
(b) Check the illumination. (1)
Connect the battery positive (+) lead to terminal A5 (IL+2) and the
negative (-) lead to terminal A8 (IL-2) of the steering pad switch
assembly connector. (2) Check that the switch illumination comes on.
OK: Steering pad switch illumination comes on. If the result is not as specified, replace the steering pad switch assembly. |
