PINPOINT TEST J : An Individual Button/Feature Is Inoperative from the RKE Transmitter: Notes
Normal Operations and Fault Conditions
The RKE feature is controlled by the TPM module and the BCM. When a button is pressed on an IKT the TIC and RKE command is received by the internal TPM module antenna. If the TPM module determines that it is a valid and programmed TIC, it sends the RKE command and TIC to the BCM over the MS-CAN. When the BCM receives the RKE command, it carries out the command by controlling the door locks or activating the horn and turn signals for the panic alarm.
The BCM disables the panic feature if the ignition key is in any position other than OFF or LOCK.
When using a key fob or a IKT to release the liftgate on vehicles with the police package option, the BCM uses a separate output to provide voltage directly to the liftgate latch. This allows the liftgate to be opened regardless of the ignition state.
