Keyless Entry: Description and Operation

The Remote Keyless Entry feature allows the doors to be locked and unlocked and the Luggage Compartment Lid to be released from up to 30 feet away from the vehicle. To unlock the driver's door, press the UNLOCK button on the Transmitter once. To unlock all of the doors, press the UNLOCK button on the Transmitter twice within 5 seconds. To lock all the doors, press the DOOR button on the Transmitter. The Luggage Compartment Lid can be opened by pressing the Trunk button. Pressing any button on the Transmitter will automatically trigger the Illuminated Entry feature.

Remote Accessory Control (RAC) Module

The RAC Module performs the Illuminated Entry, Retained Accessory Power, and Remote Keyless Entry features. The RAC Module can communicate on the Serial Data Line (SDL). The RAC Module SDL can transmit all input and output states and control every output. The SDL can place the RAC Module in the program mode.

Luggage Compartment Lid Release Relay

The Relay is energized whenever the Trunk button is pushed by having its output grounded through the RAC Module via terminal C2/J. With the Relay energized, its contacts close to apply voltage to the Luggage Compartment Lid Release Actuator: the Luggage Compartment Lid Latch releases.

Assembly Line Diagnostic Link (ALDL) Connector

The Assembly Line Diagnostic Link (ALDL) provides a program line to the RAC Module. When ALDL terminal G is grounded, all doors will lock then unlock. When a Transmitter button is pushed, the receiver will be programmed to that Transmitter. All doors lock then unlock as a feedback.

LH Front Door Isolation Relay

The Relay, when energized, isolates the driver's door lock motor from the other three motors. When the UNLOCK button on the Transmitter is pressed, the RAC Module turns on its output at C2/G. This grounds the coil of the Relay. With the Relay energized, the normally closed contacts open, breaking the circuit to the RH Front and Rear Door Lock Motors.

Door Lock Relay Assembly

This Relay, when energized on terminal A, will lock the vehicle doors. When energized on terminal F, the vehicle doors unlock. The Relay Assembly can be energized by either of the Front Door Lock Switches or the Door Lock/ Unlock Outputs of the RAC Module.
