Remote Switch: Description and Operation
SYSTEM OPERATION
Remote Radio Switch Operational View
A remote radio control switch option is available on LXI models sold in North America with the AM/FM/ cassette/S-band graphic equalizer with
CD changer control feature (RBN sales code), or the AM/FM/CD/ cassette/3-band graphic equalizer (RAZ sales code) radio receivers. Two
rocker-type switches are mounted on the back (instrument panel side) of the steering wheel spokes. The switch on the left spoke is the seek switch
and has seek up, seek down, and preset station advance functions. The switch on the right spoke is the volume control switch and has volume up,
and volume down functions.
These switches are resistor multiplexed units that are hard-wired to the Body Control Module (BCM) through the clockspring. The BCM sends
the proper messages on the Chrysler Collision Detection (CCD) data bus network to the radio receiver. For diagnosis of the BCM or the CCD data
bus, the use of a DRB scan tool and the proper Diagnostic Procedures manual are recommended. For more information on the operation of the
remote radio switch controls, refer to the owner's manual in the vehicle glove box.
