Test I: The Remote Keyless Entry (RKE) Transmitter Is Inoperative

PINPOINT TEST I: THE REMOTE KEYLESS ENTRY (RKE) TRANSMITTER IS INOPERATIVE

Normal Operation
Remote locking and unlocking of the doors, releasing the luggage compartment lid, and activation of the panic alarm is accomplished by the driver door module (DDM) receiving a command message from the remote keyless entry (RKE) transmitter. The DDM processes the command and energizes the appropriate relays to lock or unlock the doors, open/close the luggage compartment lid, or sends a message over the standard corporate protocol (SCP) network to the lighting control module (LCM) to activate the parking lamps and horn for the panic alarm.

The RKE transmitters and DDM also utilize a rolling code to prevent the code from being "captured" by a code grabber. The system advances the counter in the RKE transmitter and DDM every time an RKE transmitter button is pressed.












This pinpoint test is intended to diagnose the following:
- RKE transmitter battery
- RKE transmitter button pressed a substantial amount of times while outside the range of the vehicle
- RKE transmitter programming
- RKE transmitter
- Tire pressure monitoring system (TPMS)/RKE antenna
- DDM
