Remote Switches

WARNING: This page is about a different car, the 2009 Dodge Caliber. However, it is still accessible from the selected car via links, so may be relevant.

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. For information on the use of the scan tool, refer to the appropriate Diagnostic Service information.

For complete circuit diagrams, refer to SYSTEM WIRING DIAGRAMS .

Disconnect and isolate the battery negative cable.
Remove the remote radio switch(es) from the steering wheel. See Electrical/Audio and Video/SWITCH, Remote Radio - Removal .

Use an ohmmeter to check the switch resistance as shown in the Remote Radio Switch Test table below.

REMOTE RADIO SWITCH TEST

Switch	Switch Position	Resistance
Right (White)	Volume Up	1.210 Kilohms
Right (White)	Volume Down	3.010 Kilohms
Right (White)	Mode Advance	0.0511 Kilohms
Left (Black)	Seek Up	0.261 Kilohms
Left (Black)	Seek Down	0.681 Kilohms
Left (Black)	Pre-Set Station Advance	0.162 Kilohms

If the switch resistance checks OK, go to 5. If not OK, replace the faulty switch.
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.
Unplug the connector from the Cab Compartment Node (CCN). 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.
Check for continuity between the radio control circuit cavities of the remote radio switch wire harness connector and the CCN wire harness connector. There should be continuity. If OK, refer to the proper Diagnostic information to test the CCN and the CAN data bus. If not OK, repair the open circuit as required.
