DESCRIPTION AND OPERATION

Anti-Theft

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

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

The vehicle is equipped with Integrated Keyhead Transmitter (IKT) keys.

Passive Anti-Theft System (PATS) Function

This vehicle is equipped with 2 IKT PATS keys. The IKTs operate as a standard PATS key with a Remote Keyless Entry (RKE) transmitter incorporated into the keyhead. The IKTs require batteries for the RKE transmitter to operate. The IKT battery is not necessary for PATS operation. A maximum of 4 IKT keys can be programmed to operate the vehicle. If more than 4 IKT keys are programmed, the RKE portion of the additional keys do not operate and the SJB (and the Instrument Panel Cluster (IPC)) sets a DTC and INT KEY COULD NOT PROGRAM is displayed in the message center. 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 section, the PATS portion of the IKT key is referred to as a PATS key.

PATS consists of the following components:

PATS is not compatible with aftermarket remote start systems, which allow the vehicle to be started from the exterior of the vehicle. These systems can reduce the security of the vehicle, and also can cause no-start concerns. Remote start systems must be removed from the vehicle before any PATS -related no-start concerns are investigated.

PATS disables the vehicle from starting if there is:

The vehicle is originally equipped with IKTs manufactured by Huf. Replacement IKTs made by Strattec works correctly, but may look and feel different. It is recommended that IKTs be replaced with the same manufacturer's keys. Rotunda supplies matching keys by the same manufacturer if they are ordered by vehicle.

 

MyKey™ Feature

The MyKey™ feature allows a restricted driving mode to be programmed into one (or more) key(s) supplied with the vehicle or into any ( PATS ) programmed spare key(s) to promote good driving habits. The MyKey™ is a restricted key for all consecutive key cycles until the MyKey™ restricted key is cleared. The remaining key(s) is referred to as an "administrator key" or admin key. There must always be at least one admin key. The IPC does not allow the last admin key to be programmed into a MyKey™ restricted key. Both the admin key and the MyKey™ can be used to see how many admin keys and MyKey™ restricted keys are programmed to the vehicle, and how many total miles have been driven with the MyKey™ restricted key active.

When the MyKey™ feature is programmed, several features are modified including:

Refer to Information and Message Center in the Description and Operation portion of Section 413-01 for all of the MyKey™ system checks and system warning displays.

Refer to MyKey® Programming in this section or to the Owner's Literature for MyKey™ programming information.

Check MyKey™ System Status

The vehicle system check provides the status of the following MyKey™ parameters:

Refer to the Owner's Literature for information on accessing the MyKey system status in the message center.

Using MyKey™ with Aftermarket Remote Start System

When using an aftermarket remote start system, the default settings recognize the remote start system as an additional admin key. If the remote start system has not been programmed as a MyKey™ and the driver is a MyKey™ driver, the driver could drive the vehicle using the remote start system as an admin key with no MyKey™ restrictions. If requested by the customer to resolve this concern, the aftermarket remote start system needs to be programmed as a MyKey™. For information on programming the aftermarket remote start system as a MyKey™, refer to MyKey® Programming in this section.
