Keyless Entry: Description and Operation
ILLUMINATED ENTRYThe Illuminated Entry System is available on vehicles equipped with the Remote Keyless Entry system. The Illuminated Entry System turns ON the courtesy lamps when the remote keyless entry system is activated.
The Remote Keyless Entry Module and the Body Control Module (BCM) are used to control the system. Courtesy lamps will turn on for 30 seconds (± 1 second) and "fade-to-OFF" over a five second period.
The Illuminated Entry System also turns ON the courtesy lamps when a door is opened. The courtesy lamps will remain ON while the door is open, then "fade-to-OFF" 30 seconds (± 1 second) after the last door is closed.
The courtesy lamps will "fade-to-OFF" immediately when the ignition is switched to ON.
The Illuminated Entry System cannot be activated during the 30 second (± 1 second) period after the ignition switch is turned OFF except by using the RKE transmitter. If a door is opened and closed during this 30 second period, the system will function as previously described.
The courtesy lamps will fade to OFF immediately, if the Remote Keyless Entry lock function is actuated with all doors closed.
REMOTE KEYLESS ENTRY (RKE) SYSTEM
Key Fob Transmitter:
The key fob transmitter has three buttons to actuate and program the Remote Keyless Entry (RKE) system.
- UNLOCK: Pressing the UNLOCK button once will unlock the driver door and activate the illuminated entry system and disarm Vehicle Theft Security System, if equipped. Pressing the UNLOCK button twice within five seconds will unlock all doors and activate the illuminated entry system.
- LOCK : Pressing the LOCK button locks all doors and sounds horn (chirp) and arm the Vehicle Theft Security System. The chirp verifies the door lock operation.
- PANIC : Pressing the PANIC button sounds the horns at half second intervals, flashes the exterior lamps, and turns ON the interior lamps. The panic alarm will remain on for three minutes, or until the PANIC button is actuated again or the ignition switch is turned to the RUN position.
The Remote Keyless Entry Module is capable of retaining the transmitter Vehicle Access Code(s) (VAC) in its memory even after vehicle power has been interrupted.
The RKE system activates the optional memory seat and mirror system, if equipped. Two primary key fob transmitters can be programmed to actuate memory seat and mirror setting 1 or 2. Two additional key fob transmitters can be added, but they will not be able to operate the memory seat and mirror system.
VEHICLE ACCESS CODE (VAC)
The RKE module is capable of retaining up to four different Vehicle Access Codes.
Whenever the vehicle battery power is interrupted the RKE Module will retain all vehicle access codes in its memory. When replacing or adding a key fob transmitter (maximum 4) a DRB III scan tool is required to program the RKE Module to accept the new Vehicle Access Code. Refer to Programming RKE Module or the Proper Body Diagnostic Procedures.
