3. Use an ohmmeter to check the switch resistance as shown in the Remote Radio Switch Test table.
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 Step 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 Step 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 Step 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 Powertrain Management/Computer and Control Systems/proper Diagnostic Procedures
