Principles of Operation (How Does It Work?)

The electronic door lock control system has two main components: the Remote Keyless Entry (RKE) module with integral receiver, located behind the B-pillar on the driver side, and a three-button (hand-held) RKE transmitters.

The RKE module controls the following functions:
^ Unlocks the driver front door.
^ Unlocks all doors.
^ Locks all doors.
^ Turns on the interior lamps when using a remote transmitter.
^ Activates and deactivates a personal security panic alarm feature that sounds the horn and flashes the parking lamps.
^ Activates the lock verify feature that sounds the horn when the lock button is pressed on the remote transmitter twice within three seconds.
^ Remembers to lock the sliding door if the door locks are activated when the sliding door is open.

The electronic door lock control system receives input from the following:
^ Ignition switch.
^ Door lock switch.
^ Program connector.
^ Lamp switch.
^ Remote transmitter.

The system distributes output to the following:
^ Interior lamps.
^ Power door lock actuators.
^ Horn relay.
^ Parking lamps.

The electronic door lock control system is supplied with two three-button, hand-held remote transmitters.

The remote transmitters have three different shaped buttons, with icons used to identify the lock, unlock, and panic features.

NOTE: The electronic door lock control features will not function when the key is in run or accessory.

To unlock the driver front door, press the unlock button once on a remote transmitter that has been programmed into the RKE module.

To unlock all doors, press the unlock button on a remote transmitter twice. The second press must be within three seconds of the first. If more than five seconds have elapsed since the first press of the unlock button, pressing the unlock button again will only unlock the driver front door.

To turn on the interior lamps, press the unlock button.

To lock all doors, press the lock button on a remote transmitter once. If the sliding door was open during the lock operation, the memory lock feature will activate to lock the sliding door after it is closed again. Pressing the lock button a second time within three seconds will lock the locks again and activate the lock verify feature which will provide a "chirp" from the horn.

To activate the personal security alarm, press the panic button on a transmitter. The horn will sound and the parking lamps will flash for a maximum of three minutes. Activating the panic alarm also illuminates the interior lamps.

To deactivate the personal security alarm, press the panic button on the same remote transmitter that was used to activate the alarm, or turn the key on.

The RKE module will erase all previous remote transmitters from memory when the remote transmitters are programmed or reprogrammed.

NOTE: The RKE module can store up to four remote transmitters in memory.

When troubleshooting the electronic door lock control system, it is essential that the customer leaves at least one remote transmitter with the vehicle.

If the customer has purchased additional remote transmitters, lost one, or if one must be reprogrammed into the RKE module, all remote transmitters must be available for reprogramming at the same time.
