TRANSMITTER REPROGRAMMING
If the transmitter and/or receiver are replaced, perform the following programming procedure:
Turn the ignition to ON.
Turn the radio to OFF.
Press the RESET button on the driver information center (DIC) in order to clear any IPC warning messages.
Press and release the OPTIONS button on the DIC to scroll through the display options until the IPC display is blank.
Press and hold the RESET button for 3 seconds.
Press the OPTIONS button until FOB TRAINING message is displayed.
Important: If the FOB TRAINING message cannot be displayed, check if the BCM is configured with the correct RPO codes.
Press the RESET button in order to begin the programming sequence. The message HOLD LK + UNLK 1ST FOB will be displayed.
Simultaneously press and hold the LOCK and UNLOCK buttons on the first transmitter for 15 seconds. The IPC will indicate when that transmitter is programmed and when to proceed to the next. Repeat this procedure for each additional transmitter or press the OPTIONS button to exit.
Up to three transmitters may be programmed.
Note: The receiver will cancel the programming sequence if either three transmitters have been programmed or no transmitters have been programmed for 2 minutes.
