WARNING: This page is about a different car, the 2011 RAM Pickup and 2011 RAM Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
Any diagnosis of the Audio system should begin with the use of a scan tool. For information on the use of the scan tool, refer to the appropriate Diagnostic Service information.
Refer to the appropriate wiring information.
WARNING:
Disable the airbag system before attempting any steering wheel, steering column, seat belt tensioner, side airbag or instrument panel component diagnosis or service. Refer to RESTRAINTS - SERVICE INFORMATION article. Disconnect and isolate the negative battery (ground) cable. Wait two minutes for the airbag system capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the airbag system. Failure to follow these instructions may result in accidental airbag deployment and possible serious or fatal injury.
