Diagnostic Test
1.
MEASURE WIPER SWITCH MUX CIRCUIT VOLTAGE
Note: If any BCM DTCs are set, diagnose them first before continuing.
Disconnect the BCM harness connector.
Note: Check connectors - Clean/repair as necessary.
Turn the ignition on.
Measure the voltage of the Wiper Switch Mux circuit at cavity 65 of the
BCM harness connector.
Is voltage present?
Yes >> Go to 2
No >> Replace the Body Control Module. (Refer to 8 - ELECTRI-
CAL/ELECTRONIC CONTROL MODULES/BODY CON-
TROL/CENTRAL TIMER MODUL - REMOVAL).
Perform BODY VERIFICATION TEST.
2.
MEASURE MULTI-FUNCTION SWITCH VOLTAGE
Turn the ignition off.
Disconnect the Multi-Function Switch harness connector.
Note: Check connectors - Clean/repair as necessary.
Turn the ignition on.
Measure the voltage of the Wiper Switch Mux circuit at cavity 7 of the
Multi-Function Switch harness connector.
Is voltage present?
Yes >> Repair the Wiper Switch Mux circuit for a short to voltage.
Perform BODY VERIFICATION TEST.
No >> Replace the Multi-Function Switch. (Refer to 8 - ELECTRI-
CAL/LAMPS/LIGHTING - EXTERIOR/MULTI-FUNCTION
