Anti-Theft - Passive Anti-Theft System (PATS)
Anti-Theft
Passive Anti-Theft System (PATS) consists of the following components:
- Integrated Keyhead Transmitter (IKT)
- PATS transceiver
- Body Control Module (BCM)
- PCM
PATS protects the vehicle from theft by preventing the engine from starting unless a programmed IKT is used.
Passive Anti-Theft System (PATS) Operation
PATS prevents the engine from starting by disabling the starter relay and fuel injector operation. If an unprogrammed key is used or if there is a PATS system concern, "STARTING SYSTEM FAULT" is displayed in the message center and the engine will not start. PATS cannot disable an already running engine.
Passive Anti-Theft System (PATS) Keys
NOTE: The keys must have "HA" or "SA" stamped on the key blade.
IKT Without Remote Start
IKT With Remote Start
The vehicle comes equipped from the factory with two programmed IKTs. The IKT incorporates both the PATS functions and the Remote Keyless Entry (RKE) transmitter functions in a single device. During key programming procedures, the PATS and RKE transmitter of an IKT are both programmed into the BCM. In addition to the IKTs, conventional PATS keys can also be programmed to the vehicle if requested by the customer. The BCM accepts the programming of up to 8 keys. Of those 8 keys a maximum of 4 IKTs can be programmed. If more than 4 IKTs are programmed, "INT KEY COULD NOT PROGRAM" is displayed in the message center during the key programming procedure and the RKE function of that IKT is non-functional.
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 programmed spare key(s). 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 BCM 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 (excluding vehicles equipped with base AM/FM radio) 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.
- The audio system does not mute or limit the volume when a MyKey(TM) restricted key is used when equipped with the base AM/FM radio.
- 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 (excluding vehicles equipped with base AM/FM radio) can be programmed to limit the volume to 45% of the maximum volume.
- The audio system does not mute or limit the volume when a MyKey(TM) restricted key is used when equipped with the base AM/FM radio.
- 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, the traction control cannot be disabled by the MyKey(TM) driver.
Refer to Information and Message Center in the Description and Operation portion of Instrumentation, Message Center, and Warning Chimes Testing and Inspection for all of the MyKey(TM) system checks and system warning displays.
Refer to MyKey(TM) Programming Mykey 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 disabling 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(TM) Programming Mykey.
