Keyless Entry Module: Description and Operation
SYSTEM OPERATION
On models with the Remote Keyless Entry (RKE) option, a power lock and RKE module is mounted on the defrost duct beneath the instrument
panel, behind the heater-A/C control assembly This module contains the RKE receiver and the RKE system program logic. The module also
performs as a smart relay for the power door locks and RKE systems, including the lock inhibit and illuminated entry features.
The RKE receiver has a memory function to retain the vehicle access code of at least one, but no more than two transmitters. The receiver is
designed to retain the transmitter codes in memory, even if the battery is disconnected.
The power lock and RKE module receives inputs from the ignition switch, the power door lock switches, the driver door jamb switch, the key-in
ignition switch, and the headlamp switch. It also receives the radio signal input from the RKE transmitter. In response to those inputs, it is
programmed to control outputs to the power lock motors and the courtesy lamp circuits.
The power lock and remote keyless entry module cannot be repaired and, if faulty or damaged, it must be replaced.
