MODEL IDENTIFICATION
DESCRIPTION
The Remote Keyless Entry (RKE) system locks and unlocks the doors and releases the endgate by means of remote control. A receiver module is located in the left hand instrument panel, attached to the steering column support bracket. It is clipped in place and retained by 2 plastic retainers. The transmitter is hand held and may be attached to a key ring. (Scheme 33)
Three buttons control system operation. The transmitter emits a coded UHF radio signal, that is received by keyless entry control module, if the transmitter is within approximately 33 feet (10 meters) of the vehicle. The system has no effect on the normal operation of the locks or rear window release. The transmitter is battery powered, water resistant, and supplied in pairs to each vehicle.
The control module is only capable of recognizing 2 transmitters per vehicle. Replacement transmitters may be obtained but must be matched to the control module. See PROGRAMMING .

OPERATION

(Scheme 33) When the button marked REAR is depressed, the rear window unlocks from the endgate.
