For a complete Wipers/Washers Circuit Diagram, (Refer to 8 - ELECTRICAL/WIPERS/WASHERS - SCHEMATICS
AND DIAGRAMS).
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

BODY VERIFICATION TEST
BODY VERIFICATION TEST
1.
Turn the ignition off.
Disconnect all jumper wires and reconnect all previously disconnected components and connectors.
Note: If the SKREEM or the PCM was replaced, refer to the service information for proper programming
procedures.
If the Body Control Module was replaced, turn the ignition on for 15 seconds (to allow the new BCM to learn VIN)
or engine may not start.
Program all RKE transmitters and other options as necessary.
With the DRB III
T
, erase all Diagnostic Trouble Codes (DTCs) from ALL modules. Start the engine and allow it to
run for 2 minutes. Operate all functions of the system that caused the original complaint.
Ensure that all accessories are turned off and the battery is fully charged.
Turn the ignition off and wait 5 seconds. Turn the ignition on and using the DRB III
T
, read DTCs from ALL modules.
Are any DTCs present or is the original complaint still present?
Are any DTCs present?
YES
>> Repair is not complete, refer to appropriate symptom.
NO
>> Repair is complete.
