Keyless Entry Module: Description and Operation
POWER LOCK/REMOTE KEYLESS ENTRY MODULEThe power lock/remote keyless entry module is mounted on the dash panel beneath the instrument panel, above the heater-A/C air distribution duct and between the two defroster outlets. This module contains the remote keyless entry receiver, program logic, and functions as a smart relay for the power door lock, remote keyless entry and illuminated entry systems.
The remote keyless entry 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 module receives inputs from the ignition switch, power door lock switches, and the side/rear cargo door jamb switches. It also receives input from the remote keyless entry transmitter. In response to those inputs, it is programmed to control outputs to the lock motor and courtesy lamp circuits. The power lock/remote keyless entry module cannot be repaired and, if faulty, must be replaced.
