Remote Keyless Entry
REMOTE KEYLESS ENTRY MODULEThe Remote Keyless Entry module controls the Power Door Locks and the Vehicle Theft Security System (VTSS). It also wakes up the Instrument Cluster to turn on the illuminated entry when it senses a signal from the RKE transmitter. The module communicates with other modules via the PCI bus circuit.
The RKE module monitors the Occupant Restraint Controller messages for the purpose of monitoring the deployment of the airbag. Upon receiving that message along with the verification that the ignition is on and the vehicle speed is zero, it will provide the "enhanced accident response feature". This feature will cause the module to unlock-all doors immediately and the instrument cluster to turn the courtesy lamps on when the vehicle reaches 0 mph.
The RKE module communicates with the Powertrain Control Module to receive vehicle speed information to activate the rolling door lock feature, receive the "okay to lock" message, and receive body style information. Two transmitters are supplied with the vehicle but a total of 4 can be programmed to the module. The horn chirp on vehicle lock command is customer programmable.
To limit the amount of battery drain during storage, the IOD fuse may be removed.
VEHICLE THEFT SECURITY SYSTEM
When the VTSS is armed, it will monitor the ignition switch status, ajar switches for the vehicle doors and decklid. Also monitored is a decklid security switch (knockout) for the cylinder lock. If the alarm is tripped, it will sound the vehicles horn, flash the exterior lamps and the VTSS indicator located in the instrument cluster.
Arming the system is accomplished by locking the doors with the door lock switch following a normal exit sequence of opening the door pressing the power lock button and closing the door, by using the driver door cylinder lock switch or by pressing the RKE lock button. After all the doors are closed, the VTSS indicator will flash quickly for sixteen-seconds indicating the pre-arm process, after which it will flash at a slower rate indicating the system is armed. If during the pre-arm process a door is opened, the ignition is turned to the Run/Start position or if the RKE module receives an unlock request the system will automatically be disarmed. If the VTSS indicator stays on steady during prearm, it is an indication of an open decklid security switch sense circuit.
Disarming can be accomplished with a RKE unlock, turning the ignition on with a valid Sentry key or unlocking the vehicle with the driver door cylinder lock. All of the switches for the VTSS system can be monitored using the DRB III. The DRB III is also useful to determine the cause of a customer complaint of the alarm going off with no apparent reason.
VEHICLE THEFT SECURITY SYSTEM (Export Only)
When the VTSS is armed, it Will monitor the interior of the vehicle for movement via an intrusion sensor (if equipped), the ignition switch status, ajar switches for the vehicle doors, decklid and hood. Vehicles without an intrusion sensor will have a decklid security switch (knockout) which will also be monitored. If the alarm is tripped, it will sound the vehicles horn or a battery backed siren for vehicles equipped with the intrusion sensor, flash the exterior lamps and the VTSS indicator located in the instrument cluster.
Arming the system is accomplished by locking the doors with the door lock switch following a normal exit sequence of opening the door pressing the power lock button and closing the door, or by using either door cylinder lock switch or by pressing the RKE lock button. After all the doors are closed, the VTSS indicator will flash quickly for sixteen-seconds indicating the pre-arm process, after which it will flash at a slower rate indicating the system is armed. If during the pre-arm process a door is opened, the ignition is turned to the Run/Start position or if the RKE module receives an unlock request the system will automatically be disarmed. If the VTSS indicator stays on steady during prearm, it is an indication of the hood ajar circuit being shorted (hood opened) or the decklid security switch circuit being open (if equipped). Defeating the intrusion sensor feature for vehicles so equipped can be done by three additional lock request to the RKE module within 5 seconds.
Disarming is done by either a RKE unlock or turning the ignition on with a valid Sentry key. All of the switches for the VTSS system can be monitored using the DRB III. The DRB III is also useful to determine the cause of a customer complaint of the alarm going off with no apparent reason.
