Keyless Entry: Description and Operation

RKE/VTSS
The highline CTM provides for Remote Keyless Entry (RKE). The base CTM is not able to provide these functions. The presence of this option dictates that the vehicle is equipped with a high line CTM. The VTSS system monitors the doorjamb switches and ignition switch to detect unauthorized entry into the vehicle. Once the vehicle is "armed", any one of these inputs can cause the VTSS system to be tripped. Once tripped, the horn and lights will pulse for 3 minutes and if an attempt is made to start the engine, it will start and stall. If the trigger condition is still present, the lights will continue to flash and return to the "armed" state. The cause of the last 4 alarm triggers is stored by the CTM and may be retrieved by the DRB. The system may be disarmed by either an unlock command from a valid RKE key fob or by using a key in either door. Both front door key cylinders and equipped with disarm switches. There is also a VTSS lamp on the dash that provides information to the driver about the state of the vehicle theft system.

The RKE system is placed in the programming model by the DRB. The system will store up to four key fob codes. Through the DRB, programming of one key fob without deleting the others is possible. If the key fob is stolen, all the fob codes stored previously may be erased to provide the owner of the vehicle with an extra sense of security.
