Keyless Entry Module: Description and Operation
On models with the optional Remote Keyless Entry (RKE) system, an RKE module is mounted in the mini-dome lamp housing, or in the overhead console housing on the vehicle headliner. The RKE module contains a radio frequency receiver and the RKE system program logic. The RKE module also serves as a smart relay to control the illuminated entry feature included with the RKE system.The RKE module has a memory function to retain the vehicle access codes of at least one, but no more than four RKE transmitters. The module is designed to retain these transmitter codes in its memory, even if the battery is disconnected.
The RKE system for this vehicle also features a customer programmable horn chirp feature. This feature allows the customer the option of enabling or disabling the horn chirp request that the RKE module issues as an audible indication that a valid Lock signal has been received from the RKE transmitter. (Refer to POWER LOCKS/RE- MOTE KEYLESS ENTRY MODULE - STANDARD PROCEDURE - MODULE PROGRAMMING).
The Remote Keyless Entry (RKE) module receives inputs from the battery, the driver door ajar switch, and the Chrysler Collision Detection (CCD) data bus. It also receives the radio frequency inputs from the RKE transmitter. In response to those inputs, it is programmed to control outputs to the power lock motors, the courtesy lamp circuits, and the horn relay.
The RKE module cannot be repaired and, if faulty or damaged, it must be replaced.
