Anti-Theft - Passive Anti-Theft System (PATS)
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 (Integrated Keyhead Transmitter) PATS (Passive Anti-Theft System) keys. The IKTs (Integrated Keyhead Transmitters) operate as a standard PATS (Passive Anti-Theft System) key with a Remote Keyless Entry (RKE) transmitter incorporated into the keyhead. The IKTs (Integrated Keyhead Transmitters) require batteries for the RKE (Remote Keyless Entry) transmitter to operate. The IKT (Integrated Keyhead Transmitter) battery is not necessary for PATS (Passive Anti-Theft System) operation. A maximum of 4 IKT (Integrated Keyhead Transmitter) keys can be programmed to operate the vehicle. If more than 4 IKT (Integrated Keyhead Transmitter) keys are programmed, the RKE (Remote Keyless Entry) portion of the additional keys do not operate and the SJB (Smart Junction Box) (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 (Remote Keyless Entry) system. If additional PATS (Passive Anti-Theft System) keys are desired, a standard PATS (Passive Anti-Theft System) key (a non-IKT (Integrated Keyhead Transmitter) key) can be used. For the purposes, the PATS (Passive Anti-Theft System) portion of the IKT (Integrated Keyhead Transmitter) key is referred to as a PATS (Passive Anti-Theft System) key.
PATS (Passive Anti-Theft System) consists of the following components:
- Anti-theft indicator (located in the IPC (Instrument Panel Cluster) and depicts a vehicle with a padlock covering part of it)
- IKT (Integrated Keyhead Transmitter) key(s) (the key contains a PATS (Passive Anti-Theft System) transponder and an RKE (Remote Keyless Entry) transmitter)
- PATS (Passive Anti-Theft System) transceiver (located around the ignition lock cylinder)
- IPC (Instrument Panel Cluster)
- PCM
PATS (Passive Anti-Theft System) 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 (Passive Anti-Theft System) -related no-start concerns are investigated.
PATS (Passive Anti-Theft System) disables the vehicle from starting if there is:
- a damaged IKT (Integrated Keyhead Transmitter) key.
- an unprogrammed IKT (Integrated Keyhead Transmitter) key.
- a non-encoded (non-PATS (Passive Anti-Theft System)) key (a conventional key or one that does not have any electronics).
- damaged wiring.
- a damaged transceiver.
- a damaged IPC (Instrument Panel Cluster).
- a damaged PCM.
The vehicle is originally equipped with IKTs (Integrated Keyhead Transmitters) manufactured by Huf. Replacement IKTs (Integrated Keyhead Transmitters) made by Strattec works correctly, but may look and feel different. It is recommended that IKTs (Integrated Keyhead Transmitters) be replaced with the same manufacturer's keys. Rotunda supplies matching keys by the same manufacturer if they are ordered by vehicle.
MyKey(TM) Feature
The MyKey(TM) feature allows a restricted driving mode to be programmed into one (or more) key(s) supplied with the vehicle or into any (PATS (Passive Anti-Theft System)) programmed spare key(s) to promote good driving habits. The MyKey(TM) is a restricted key for all consecutive key cycles until the MyKey(TM) 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 (Instrument Panel Cluster) does not allow the last admin key to be programmed into a MyKey(TM) restricted key. Both the admin key and the MyKey(TM) can be used to see how many admin keys and MyKey(TM) restricted keys are programmed to the vehicle, and how many total miles have been driven with the MyKey(TM) restricted key active.
When the MyKey(TM) feature is programmed, several features are modified including:
Standard Restricted Features
- NOTE: The standard restricted features below cannot be configured in any way.
Belt-Minder(R) chimes periodically with the audio system muted until the driver safety belt is buckled. If Belt-Minder(R) has been disabled when the admin key is in the vehicle, Belt-Minder(R) still functions for the MyKey(TM) driver. Belt-Minder(R) cannot be disabled by the MyKey(TM) driver.
- Audible and visual low fuel warnings are issued when the programmed Distance To Empty (DTE) value is reached (typically 75 miles).
- The parking aid system (if equipped) cannot be turned off.
Optional Restricted Features
- NOTE: The optional restricted features below can be configured to the customer preferences.
The volume of the audio system can be programmed to limit the volume to 45% of the maximum volume.
- Vehicle speed can be programmed to be limited to 130 km/h (80 mph). Audible and visual warnings are issued when the vehicle speed of 130 km/h (80 mph) is attained.
- Audible and visual warnings are issued when the preselected vehicle speed of 75, 90 or 105 km/h (45, 55 or 65 mph) is attained.
- The AdvanceTrac(R) always on feature can be configured on or off. If configured to always on, at this time the traction control cannot be disabled by the MyKey(TM) driver.
Refer to Information and Message Center in the Description and Operation of Instrument Panel, Gauges and Warning Indicators for all of the MyKey(TM) system checks and system warning displays.
Refer to MyKey(R) Programming or to the Owner's Literature for MyKey(TM) programming information.
Check MyKey(TM) System Status
The vehicle system check provides the status of the following MyKey(TM) parameters:
- MYKEY DISTANCE- This odometer only tracks mileage when a MyKey(TM) is used. If mileage does not accumulate, the intended MyKey(TM) is not being used. The only way to reset this odometer to zero is by clearing the MyKey(TM). If this odometer is lower than the last time it was checked, the MyKey(TM) system has been cleared.
- MYKEY(S) PROGRAMMED- Indicates how many MyKeys(TM) are programmed to the vehicle. It can also be used to determine if a MyKey(TM) has been cleared.
- ADMIN KEYS PROGRAMMED- Indicates how many admin keys are programmed to the vehicle. It can also be used to determine if an additional spare key has been programmed to the vehicle.
Refer to the Owner's Literature for information on accessing the MyKey system status in the message center.
Using MyKey(TM) 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(TM) and the driver is a MyKey(TM) driver, the driver could drive the vehicle using the remote start system as an admin key with no MyKey(TM) restrictions. If requested by the customer to resolve this concern, the aftermarket remote start system needs to be programmed as a MyKey(TM). For information on programming the aftermarket remote start system as a MyKey(TM), refer to MyKey(R) Programming .
