Diagnosis And Testing - Left MULTIFUNCTION Switch

Refer to SYSTEM WIRING DIAGRAMS .

1. Disconnect and isolate the battery negative cable. Disconnect the instrument panel wire harness connector from the multi-function switch connector.
2. Using an ohmmeter, perform the continuity and resistance tests at the terminals in the left multi-function switch connector (refer to MULTI-FUNCTION SWITCH - BLACK 12 WAY ) as shown in the LEFT MULTI-FUNCTION SWITCH CONTINUITY/RESISTANCE TEST table.
