Keyless Entry System Description and Operation - Passive Passive keyless entry allows entry to a locked vehicle without pressing any buttons on the keyless entry transmitter. You must only have the transmitter with you. This passive system is also part of the vehicle starting system. It allows you to start and run the vehicle having only the transmitter as your key. The passive entry and starting system use low frequency antennas in 4 different areas on the vehicle to determine the location of the transmitter. When passively opening a locked door or the rear compartment lid, you must have a programmed transmitter with you in your pocket, purse, or briefcase. As a customer opens the door handle or presses rear compartment touch pad, the low frequency antenna sends out a challenge to the keyless entry transmitter. The transmitter must be in a one meter range of the door or rear compartment lid in order to receive the challenge. If the challenge is met, the transmitter will respond, allowing the door to be unlocked and opened. Passive entry allows you to operate the following features: • Passive door unlock/unlatch • Passive rear compartment lid release • Illuminated entry lamps • Vehicle starting The keyless entry system has the following components: • Keyless entry transmitters • LH and RH door antennas (part of the door handle assembly) • Rear compartment antenna • Console passive antenna • Console active antenna • Instrument Panel Module (IPM) • Rear Integration Module (RIM) • Remote Control Door Lock Receiver (RCDLR) • External RF Antenna (includes coax from RCDLR to back glass)
Remote Control Door Lock Receiver (RCDLR) The RCDLR is a multi-function module which controls all the vehicles antennas for passive keyless entry functions. The RCDLR also acts as the receiver for active keyless entry and tire pressure monitoring (TPM) functions, as well as controlling all immobilizer functions. The RCDLR's RF antenna is located in the back glass, and there is a coax cable connecting the glass antenna to the module located in the trunk.
Your best bet , take it to a qualified repair shop that has the factory Tech 2 scan tool or someother professional type scanner that can read • Rear Integration Module (RIM) DTC'S - diagnostic trouble codes .
