Description And Operation: Anti-Theft: Notes

NOTE: The Smart Junction Box (SJB) is also known as the Generic Electronic Module (GEM).

The perimeter alarm system is controlled by the SJB on vehicles equipped with Integrated Keyhead Transmitter (IKT) keys. On vehicles equipped with Intelligent Access (IA) keys, the perimeter alarm system is controlled by the Remote Function Actuator (RFA) module.

The vehicle can be equipped with a conventional PATS (standard) or with IA with push button start (option). The conventional PATS vehicle uses an IKT key and the vehicle equipped with IA with push button start uses an IA key. The IA key does not use a typical key blade found on most conventional-type keys, although the IA key does contain a backup mechanical key blade that can be used in the driver door lock cylinder to unlock the driver door in an emergency. This action (using the backup mechanical key blade in the door lock cylinder) is monitored by the Driver Door Module (DDM) and this information is sent to the RFA module (with IA key) over the Medium Speed Controller Area Network (MS-CAN).
