Anti-Theft
Passive Anti-Theft System (PATS) Without Intelligent Access (IA)
Passive Anti-Theft System (PATS) consists of the following components:
- Integrated Keyhead Transmitter (IKT)
- PATS (Passive Anti-Theft System) transceiver
- Body Control Module (BCM)
- PCM
PATS (Passive Anti-Theft System) protects the vehicle from theft by preventing the engine from starting unless a programmed IKT (Integrated Keyhead Transmitter) is used.
Passive Anti-Theft System (PATS) Operation
PATS (Passive Anti-Theft System) 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 (Passive Anti-Theft System) system concern, STARTING SYSTEM FAULT is displayed in the message center and the engine will not start. PATS (Passive Anti-Theft System) cannot disable an already running engine.
Passive Anti-Theft System (PATS) Keys
NOTE: The IKTs (Integrated Keyhead Transmitters) must have SA stamped on the keyblade. Conventional PATS (Passive Anti-Theft System) keys must have HA or SA stamped on the keyblade.
IKT (Integrated Keyhead Transmitter) Without Remote Start and Power Liftgate
The vehicle comes equipped from the factory with 2 programmed IKTs (Integrated Keyhead Transmitters). The IKT (Integrated Keyhead Transmitter) incorporates both the PATS (Passive Anti-Theft System) and the Remote Keyless Entry (RKE) transmitter functions in a single device. During key programming procedures, the PATS (Passive Anti-Theft System) and RKE (Remote Keyless Entry) transmitter of an IKT (Integrated Keyhead Transmitter) are both programmed into the BCM (Body Control Module). In addition to the IKTs (Integrated Keyhead Transmitters), conventional PATS (Passive Anti-Theft System) keys can also be programmed to the vehicle if requested by the customer. The BCM (Body Control Module) accepts the programming of up to 8 keys. Of those 8 keys a maximum of 4 IKTs (Integrated Keyhead Transmitters) can be programmed. If more than 4 IKTs (Integrated Keyhead Transmitters) are programmed, INT KEY COULD NOT PROGRAM is displayed in the message center during the key programming procedure and the RKE (Remote Keyless Entry) function of that IKT (Integrated Keyhead Transmitter) is non-functional. Refer to Key Programming Using Diagnostic Equipment Key Programming Using Diagnostic Equipment or Key Programming - Program a Key Using Two Programmed Keys Key Programming - Program a Key Using Two Programmed Keys for the key programming procedures.
Passive Anti-Theft System (PATS) With Intelligent Access (IA)
The Passive Anti-Theft System (PATS) consists of the following components:
- Intelligent Access (IA) key
- Front passive start antenna (located on the bottom of the front of the floor console)
- Center passive start antenna (located in the rear of the floor console)
- Rear passive start antenna (located under the liftgate scuff trim panel, beneath the liftgate striker)
- Backup transceiver (located in the floor console, below the audio jacks)
- Tire Pressure Monitor (TPM) module
- Remote Function Actuator (RFA) module (located behind the glove compartment)
- Body Control Module (BCM)
- PCM
Intelligent Access (IA) Passive Anti-Theft System (PATS) Operation
NOTE: The IA (Intelligent Access) feature is a programmable parameter and can be enabled/disabled with a scan tool. If the feature is disabled, the Intelligent Access (IA) feature to enter the vehicle and passive starting will be inoperative. To start the vehicle, the IA (Intelligent Access) key has to be placed in the backup slot. for information on enabling/disabling the IA (Intelligent Access) feature.
The IA (Intelligent Access) PATS (Passive Anti-Theft System) prevents the ignition from transitioning out of the OFF mode unless a programmed IA (Intelligent Access) key is detected inside the vehicle. If no programmed key is detected inside the vehicle when the start/stop switch is pressed, NO KEY DETECTED is displayed in the message center. PATS (Passive Anti-Theft System) cannot disable an already running engine.
Intelligent Access (IA) Keys
The vehicle is equipped with 2 IA (Intelligent Access) keys. The IA (Intelligent Access) key incorporates both the PATS (Passive Anti-Theft System) and the Remote Keyless Entry (RKE) transmitter functions in a single device. The IA (Intelligent Access) key must be located inside the vehicle for engine starting. During key programming procedures, the PATS (Passive Anti-Theft System) and RKE (Remote Keyless Entry) transmitter of an IA (Intelligent Access) key are both programmed into the RFA (Remote Function Actuator) module. The RFA (Remote Function Actuator) module accepts programming of up to 4 IA (Intelligent Access) keys. When the 4th IA (Intelligent Access) key is programmed KEY PROGRAMMED 4 KEYS TOTAL is displayed in the message center. If an attempt is made to program more than 4 IA (Intelligent Access) keys, MAX NUMBER OF KEYS PROGRAMMED is displayed in the message center during the key programming procedure and that IA (Intelligent Access) does not program. Refer to Key Programming Using Diagnostic Equipment Key Programming Using Diagnostic Equipment or Key Programming - Program a Key Using Two Programmed Keys Key Programming - Program a Key Using Two Programmed Keys for the key programming procedures.
Backup Transceiver
NOTE: Edge shown, MKX similar.
The backup transceiver slot is located in the floor console storage bin. This slot allows the IA (Intelligent Access) key to be placed in close proximity to the backup transceiver for engine starting purposes. If the battery in the IA (Intelligent Access) key is low or if there is excessive radio frequency interference, the NO KEY DETECTED message displays in the message center when the start/stop switch is pressed. To start the engine in the event of either of these 2 concerns, place the IA (Intelligent Access) key in the backup transceiver slot and attempt to start the engine.
Intelligent Access (IA) with Push Button Start Ignition Modes
The IA (Intelligent Access) feature does not require a conventional key to enter or start the vehicle. Once inside the vehicle, the operator activates one of the ignition modes using the brake pedal and the push button start (start/stop) switch, as follows:
Intelligent Access (IA) with Push Button Start Ignition Modes
MyKey(R) Feature
The MyKey(R) 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). The MyKey(R) is a restricted key for all consecutive key cycles until the MyKey(R) 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 (Body Control Module) does not allow the last admin key to be programmed into a MyKey(R) restricted key. Both the admin key and the MyKey(R) can be used to see how many admin keys and MyKey(R) restricted keys are programmed to the vehicle, and how many total miles have been driven with the MyKey(R) restricted key active.
When the MyKey(R) 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(R) driver. Belt-Minder(R) cannot be disabled by the MyKey(R) 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), Blind Spot Information System (BLIS(R)) with cross traffic alert (if equipped), and forward collision warning (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, the traction control cannot be disabled by the MyKey(R) driver.
Refer to Information and Message Center in the Description and Operation portion of Instrument Panel, Gauges and Warning Indicators for all of the MyKey(R) system checks and system warning displays.
Refer to MyKey(R) Programming MyKey(R) Programming or to the Owner's Literature for MyKey(R) programming information.
Check MyKey(R) System Status
The vehicle system check provides the status of the following MyKey(R) parameters:
- MYKEY DISTANCE- This odometer only tracks mileage when a MyKey(R) is used. If mileage does not accumulate, the intended MyKey(R) is not being used. The only way to reset this odometer to zero is by clearing the MyKey(R). If this odometer is lower than the last time it was checked, the MyKey(R) system has been cleared.
- MYKEY(S) PROGRAMMED- Indicates how many MyKey(R) are programmed to the vehicle. It can also be used to determine if a MyKey(R) 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(R) system status in the message center.
Using MyKey(R) 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(R) and the driver is a MyKey(R) driver, the driver could drive the vehicle using the remote start system as an admin key with no MyKey(R) restrictions. If requested by the customer to resolve this concern, the aftermarket remote start system needs to be programmed as a MyKey(R). For information on programming the aftermarket remote start system as a MyKey(R), refer to MyKey(R) Programming MyKey(R) Programming.
