Anti-Theft - Passive Anti-Theft System (PATS)
Anti-Theft
Passive Anti-Theft System (PATS) Without Intelligent Access (IA)
Passive Anti-Theft System (PATS) consists of the following components:
- Anti-theft indicator
- Integrated Keyhead Transmitter (IKT)
- PATS (Passive Anti-Theft System) transceiver (located next to the ignition lock cylinder)
- Instrument Panel Cluster (IPC)
- 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, the anti-theft indicator in the IPC (Instrument Panel Cluster) flashes rapidly and the engine will not start. PATS (Passive Anti-Theft System) cannot disable an already running engine.
Passive Anti-Theft System (PATS) Keys
The vehicle comes equipped from the factory with two programmed IKTs (Integrated Keyhead Transmitters). The IKT (Integrated Keyhead Transmitter) incorporates both the PATS (Passive Anti-Theft System) and Remote Keyless Entry (RKE) transmitter functions in a single device. The key programming is a two step procedure. PATS (Passive Anti-Theft System) information is programmed into the IPC (Instrument Panel Cluster) and then the RKE (Remote Keyless Entry) transmitter is programmed into the BCM (Body Control Module). The IPC (Instrument Panel Cluster) accepts the programming of an unlimited number of keys, and the BCM (Body Control Module) accepts the programming of up to 8 keys. Refer to Key Programming Using Diagnostic Equipment Key Programming Using Diagnostic Equipment for PATS (Passive Anti-Theft System) programming, and then refer to Remote Keyless Entry (RKE) Transmitter Programming in Doors, Hood and Trunk &/or Locks to program the RKE (Remote Keyless Entry) transmitter.
Passive Anti-Theft System (PATS) With Intelligent Access (IA)
The Passive Anti-Theft System (PATS) consists of the following components:
- IA (Intelligent Access) key
- Front passive start antenna (located in the front of the floor console just below the HVAC controls)
- Center passive start antenna (located on the bottom of the rear of the floor console)
- Rear passive start antenna (located behind the rear seat bottom cushion)
- PATS (Passive Anti-Theft System) /backup transceiver (located in the steering column)
- Remote Functions Receiver (RFR) module (located on the top of the headliner in the front)
- Remote Function Actuator (RFA) module
- PCM
Intelligent Access (IA) Passive Anti-Theft System (PATS) Operation
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 button is pressed, KEY NOT DETECTED is displayed in the Front Control/Display Interface Module (FCDIM). PATS (Passive Anti-Theft System) cannot turn the ignition off or 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 RKE (Remote Keyless Entry) transmitter functions in a single device. The IA (Intelligent Access) key must be located inside the vehicle for vehicle 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 8 IA (Intelligent Access) keys. Refer to Key Programming Using Diagnostic Equipment Key Programming Using Diagnostic Equipment for key programming information.
PATS (Passive Anti-Theft System) /Backup Transceiver
The PATS (Passive Anti-Theft System) /backup transceiver is located in the steering column in the same location as a vehicle equipped without IA (Intelligent Access). If the vehicle does not start normally, place the IA (Intelligent Access) key next to the steering column shroud and attempt to start the vehicle.
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 (automatic transaxle) or clutch pedal (manual transaxle) and the push button start (START/STOP) switch, as follows:
