Keyless Entry Module: Description and Operation
The power lock and Remote Keyless Entry (RKE) module is used on models that are not equipped with the optional Vehicle Theft Security System
(VTSS). This module is mounted on the inboard side of the left center instrument panel support. The module contains the RKE receiver and the RKE
system program logic. The relays for the power door locks, the RKE system, and the illuminated entry system are also integral to this module.
The RKE receiver has a memory function to retain the vehicle access code of at least one, but no more than two transmitters. The RKE receiver is
designed to retain the transmitter codes in memory, even if the battery is disconnected.
This RKE system includes an illuminated entry feature, which turns on the courtesy lamps for a timed interval (about 35 seconds), when the power locks
are unlocked using the RKE transmitter. This power lock system includes a delay lock feature. With the delay lock feature, if a side or rear door is still
open when a lock request is received by the power lock module, the module will automatically cycle all of the power lock motors to lock five seconds
after the doors are closed.
The power lock and RKE module receives inputs from the ignition switch, the power door lock switches, and both the side and rear cargo door jamb
switches. 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.
