Description And Operation: Anti-Theft: Notes

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

The Passive Anti-Theft System (PATS) consists of the following components:

Anti-theft indicator (located in the Instrument Cluster (IC))
Integrated Keyhead Transmitter (IKT) PATS key(s) (the key contains a transponder and a Remote Keyless Entry (RKE) transmitter)
PATS transceiver
IC
PCM

PATS uses radio frequency identification technology to deter a drive-away theft. Passive means that it does not require any activity by the user.

NOTE: This vehicle uses a Huf IKT key. If replacing an IKT key, it is recommended that the original Huf IKT key be replaced with another Huf IKT key. There are minor visual differences both externally and internally between the Huf IKT key and IKT keys used on other vehicles that may be noticed by the customer. These visual differences does not affect the IKT key functionality in any way. Rotunda should supply a Huf IKT key when ordering replacement/new keys for this vehicle. The Owner's Literature may provide additional information concerning these differences. If replacing an IKT key (or adding another key) with a standard PATS key (not an IKT key), any of the brands (Ford, Rotunda, Strattec or Huf) operates the PATS, but not the RKE system.

The vehicle is equipped with 2 IKT PATS keys. The IKTs operate as a standard PATS key with an RKE transmitter incorporated into the keyhead. The IKTs require batteries for the RKE transmitter to operate. A maximum of 4 IKT keys can be programmed to operate the vehicle. If more than 4 IKT keys are programmed, the Remote Keyless Entry (RKE) portion of the additional keys do not operate and the SJB (and the IC) sets a memory full DTC B1138. These additional keys start the vehicle, but cannot operate the RKE system. If additional PATS keys are desired, a standard PATS key (a non-IKT key) can be used. For the purposes of this information, the PATS portion of the IKT key is referred to as a PATS key.
