Diagnosis And Testing - Right MULTIFUNCTION Switch

Disconnect and isolate the battery negative cable.
Remove the right multi-function switch from the steering column and disconnect the instrument panel wire harness connector for the switch from the switch connector (Refer to REMOVAL ).

Using an ohmmeter, check the right multi-function switch continuity and resistances at the switch terminals as shown in the RIGHT (WIPER) MULTIFUNCTION SWITCH CONTINUITY/RESISTANCE.

If the right multi-function switch fails any of the continuity or resistance tests, replace the faulty right multi-function switch as required.
