Remote Radio Switches - Installation5 steps
⚠ WARNING
Disable the airbag system before attempting any steering wheel, steering column, seat belt tensioner, side airbag or instrument panel component diagnosis or service. 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.
  1. Install remote radio switch to the steering wheel.
  2. Connect the wire harness to the remote radio switch.
  3. Install the speed control switches.
  4. Install the driver side airbag Driver Air Bag - Installation.
  5. Connect the battery negative cable.

  1. Disconnect and isolate the battery negative cable. Remove the remote radio switch(es) from the steering wheel Remote Radio Switches - Removal.
  2. Use an ohmmeter to check the switch resistances as shown in the Remote Radio Switch Test chart. If the remote radio switch resistances check OK, go to 3. If not OK, replace the faulty switch. REMOTE RADIO SWITCH TEST
  3. Reconnect the battery negative cable. Turn the ignition switch to the On position. Check for 5 volts at the radio control mux circuit cavities of the steering wheel wire harness connectors for both remote radio switches. If OK, go to 4. If not OK, repair the open or shorted radio control mux circuit as required.
  4. Disconnect and isolate the battery negative cable. Disconnect the 22-way instrument panel wire harness connector from the CCN. Check for continuity between the remote radio switch ground circuit cavities of the steering wheel wire harness connectors for both remote radio switches and a good ground. There should be no continuity. If not OK, repair the shorted remote radio switch ground circuit as required.

REMOTE SWITCHES
Radio controls are mounted on the back of the steering wheel. The controls provide convenient no-look operation and operate the following functions:
Right side A rocker switch that increases or decreases the volume A push button that selects modes. Repeatedly pressing the button selects from among AM radio, FM radio and CD changer. If the vehicle is equipped with Satellite Digital Audio Radio (SDAR) or the Video Entertainment System™, these are also included in the selection.
Left side A rocker switch with functions that vary depending on the mode: in a radio mode, the frequency increases or decreases; if a CD is playing, the player skips to the next or previous track; if SDAR is playing the tuner skips to the next or previous channel. A push button that steps through preset selections: if the radio is playing, pressing the button selects the next preset frequency; if a CD is playing, the changer selects the next disc; if SDAR is playing the next preset channel is selected.
REMOTE SWITCHES
The six switches in the two remote radio switch units are normally open, resistor multiplexed momentary switches that are hard wired to the Cab Compartment Node (CCN) through the clockspring. The CCN sends a five volt reference signal to both switch units on one circuit, and senses the status of all of the switches by reading the voltage drop on a second circuit.
When the CCN senses an input (voltage drop) from any one of the remote radio switches, it sends the proper switch status messages on the Controlled Area Network (CAN) to the radio receiver. The electronic circuitry within the radio receiver is programmed to respond to these remote radio switch status messages by adjusting the radio settings as requested. For diagnosis of the CCN or the CAN data bus, the use of a scan tool and the proper Diagnostic article are recommended.
REMOTE SWITCHES
Any diagnosis of the Audio system should begin with the use of scan tool. For information on the use of the scan tool, refer to the appropriate Diagnostic information.
