Remote Switch: Testing and Inspection
.
REMOTE SWITCHES
WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, REFER TO ELECTRICAL, RESTRAINTS BEFORE ATTEMPTING ANY
STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE.
FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND
POSSIBLE PERSONAL INJURY.
Any diagnosis of the Audio system should begin with the use of the Scan Tool tool. For information on the use of the Scan Tool, refer to the
appropriate Diagnostic.
Refer to the appropriate wiring information.
1. Disconnect and isolate the battery negative cable.
2. Remove the remote radio switch(es) from the steering wheel. See: Service and Repair/Remote Radio Switches - Removal.
3. Use an ohmmeter to check the switch resistance as shown in the Remote Radio Switch Test table.
REMOTE RADIO SWITCH TEST
NOTE: The right remote radio switch back is white in color. The left switch back is black in color. The right/left remote radio switch
orientation is with the steering wheel installed, and driver in drivers seat.
4. If the switch resistance checks OK, go to 5. If not OK, replace the faulty switch.
5. Check for continuity between the ground circuit cavity of the switch wire harness connector and a good ground. There should be continuity. If OK,
go to 6. If not OK, repair the open circuit as required.
6. Unplug the 24-way white wire harness connector from the Body Control Module (BCM). Check for continuity between the radio control circuit
cavity of the remote radio switch wire harness connector and a good ground. There should be no continuity. If OK, go to 7. If not OK, repair the
short circuit as required.
7. Check for continuity between the radio control circuit cavities of the remote radio switch wire harness connector and the BCM wire harness
connector. There should be continuity. If OK, refer to the proper Diagnostic Procedures manual to test the BCM and the PCI data bus. If not OK,
repair the open circuit as required.
