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 can be equipped with either conventional PATS (standard equipment) or Intelligent Access (IA) with push button start (optional equipment). The conventional PATS vehicle uses an Integrated Keyhead Transmitter (IKT) key and the IA with push button start vehicle uses an IA key. The IA key uses radio frequency signals to be recognized by PATS as a valid, programmed key before PATS allows the vehicle to be started using the push button start.
MyKey(TM) Feature
NOTE: The MyKey(TM) feature is applicable to both key types, the IKT key and the IA key.
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) to promote good driving habits. The MyKey(TM) is a restricted key for all consecutive key cycles until the MyKey(TM) restricted key is disabled. The remaining key(s) is referred to as an "administrator key" or admin key. There must always be at least one admin key. The Instrument Panel Cluster (IPC) 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 ignition lock cylinder, 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) 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, at this time the traction control cannot be disabled by the MyKey(TM) driver.
If the vehicle is equipped with a Ford approved remote start system and the remote start system was used to start the vehicle, the remote start system causes the vehicle to stall if a door is opened or the vehicle is shifted into gear. At this time, an ignition key must be inserted into the ignition lock cylinder and cycled to the ON position. For IA vehicles, an IA key must be inside the vehicle for the vehicle to be started using the push button start. The vehicle cannot be driven unless a key is inserted into the ignition lock cylinder and turned to the ON position for IKT vehicles or an IA key must be present inside the vehicle for IA vehicles.
A remote start system (if equipped) must be a Ford approved remote start system or issues with the MyKey(TM) feature may occur.
The remote start system decreases the number of keys that can be programmed to the vehicle by one keycode.
The MyKey(TM) feature does not function if the unlimited key mode is turned on. This is applicable to IKT vehicles only. IA vehicles do not have the unlimited mode.
Refer to Information and Message Center in the Description and Operation portion of Instrument Panel, Gauges and Warning Indicators 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.
Factory Invoiced Accessory (FIA) Remote Starter
Vehicles can be equipped with a factory-invoiced dealer-installed remote start system that is a Factory Invoiced Accessory (FIA). The remote start fob for this system uses a small device that is about half the size of a conventional Remote Keyless Entry (RKE) fob, but only has one button on it. If the remote start system is installed on the vehicle and the unlimited mode is not enabled, the PATS allows up to 7 PATS keys to be programmed into the Instrument Panel Cluster (IPC). The remote start system uses up one of the 8 total PATS keys that can be programmed into the IPC. The number of keys that are programmed into PATS can be determined by viewing the IPC PID N_KEYCODE.
Passive Anti-Theft System (PATS) Function
Vehicles Equipped With Integrated Keyhead Transmitter (IKT) Key
NOTE: This vehicle uses a Strattec IKT key. If replacing an IKT key, it is recommended that the original Strattec IKT key be replaced with another Strattec IKT key. There are minor visual differences both externally and internally between the Strattec IKT key and IKT keys used on other Ford, Lincoln, and Mercury vehicles that may be noticed by the customer. These visual differences does not affect the IKT key functionality in any way. Rotunda should supply a Strattec IKT key when ordering replacement/new keys for this vehicle. Refer to the Owner's Literature for information concerning these differences. If replacing an IKT key (or adding another key) with a standard PATS key (not an IKT key), any of the brands (Ford, Rotunda, Strattec or Huf) operates the PATS, but not the RKE system.
Vehicles with IKT keys were originally equipped with IKT keys manufactured by Strattec. Replacement IKT keys made by Huf work correctly, but can look and feel different. It is recommended that IKT keys be replaced with the same manufacturer's keys. Rotunda supplies matching keys by the same manufacturer if they are ordered by vehicle.
This vehicle is equipped with 2 IKT PATS keys. The IKTs operate as a standard PATS key with a 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 (the IPC sets DTC B109E:42) sets DTC B1138 (Memory Full). 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, the PATS portion of the IKT key is referred to as a PATS key.
The IKT key PATS consists of the following components:
- Anti-theft indicator (located in the IPC and depicts a vehicle with a padlock covering part of it)
- IKT key(s) (the key contains a PATS transponder and an RKE transmitter)
- PATS transceiver
- IPC
- PCM
PATS is active only for a few seconds when the vehicle is starting. It is not a PATS concern if the vehicle stalls after it has been running for a minimum of 3 seconds. PATS cannot disable a running vehicle.
The PATS function uses the IPC and the PCM to enable or disable the engine. All elements of PATS must be functional before the engine is allowed to start. If any of the components are not working correctly, the vehicle cannot start. If there is a PATS concern present, the IPC sends a message to the PCM to not allow fuel injector or starter operation. If the vehicle starts and stalls, or the engine does not start at all, check the anti-theft indicator operation in the IPC and if flashing or glowing, retrieve the DTCs from the IPC and the PCM and follow the PATS diagnostics.
PATS disables the vehicle from starting if there is:
- a damaged IKT key.
- an unprogrammed IKT key.
- a non-encoded (non-PATS) key (a conventional key or one that does not have any electronics).
- damaged wiring.
- a damaged transceiver.
- a damaged IPC.
- a damaged PCM.
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.
Unlimited Key Mode
PATS contains a feature called unlimited key mode (available only on vehicles with IKT keys, vehicles with IA keys do not have this feature). This feature allows a customer to program more than 8 vehicle keys, if requested. Each vehicle in unlimited key mode is set up with a special unlimited transponder security keycode. This allows all the customer vehicles to share the same mechanically cut keys. For an individual customer, any randomly selected security key that has been previously mechanically cut and electronically programmed to the vehicle is acceptable. Refer to Spare Key Programming - Unlimited Key Mode Unlimited Key Mode.
If unlimited key mode is enabled, a maximum of 4 IKT keys can be programmed to the vehicle for RKE functionality. If more keys are required, they should be standard PATS keys. If more than 4 IKT keys are programmed to the vehicle, the SJB sets DTC B1138 (Memory Full) and the IPC sets DTC B109E:42 (Remote Keyless Entry: General Memory Failure) and only 4 IKT keys have RKE functionality, however, all of them start the vehicle, if programmed correctly. Refer to Spare Key Programming - Unlimited Key Mode Unlimited Key Mode.
Vehicles Equipped With Intelligent Access (IA) Key
NOTE: The IA key must be outside the vehicle for entry purposes, and inside the vehicle for starting purposes. The IA key cannot operate the system if used in the opposite manner. In other words, the IA key cannot be used for entry if it is inside of the vehicle and it cannot be used for starting if it is outside of the vehicle. This is done for security purposes. If an IA key is inside the vehicle, and the operator is carrying another programmed IA key, IA entry is still allowed.
The vehicle is equipped with 2 IA PATS keys (Rotunda numbers are 164-R7030 for the mechanical key blade and 164-R7028 for the IA key, less the mechanical key blade). The IA key and mechanical key blade cannot be purchased together as a single unit. The IA keys operate as an electronic PATS key (there is no conventional key shank) and contain a transponder that allows the customer to access and start the vehicle without using a standard key. The IA key must be located somewhere in the vehicle for vehicle starting. A maximum of 4 IA keys can be programmed to operate the vehicle. If more than 4 IA keys are attempted to be programmed, the additional IA key(s) cannot function in any way.
The IA key requires a battery to operate the RKE functions. If the IA key battery fails or is low on charge, the IA key cannot be used to start the vehicle unless it is placed in the backup transceiver slot.
NOTE: The list below does not include the door handle antenna and the rear fascia antenna as they are not used for starting the vehicle. Refer to Doors, Hood and Trunk &/or Locks for information on these components.
PATS consists of the following components:
- Anti-theft indicator (located in the IPC and depicts a vehicle with a padlock covering part of it)
- IA key
- Front console passive start antenna (located in the front of the floor console)
- Rear console passive start antenna (located in the rear/bottom of the floor console)
- Rear seat passive start antenna (located under the middle of the rear seat cushion, attached to the floor pan)
- Backup transceiver (located in the rear of the floor console, bolted to the rear of the console under the rear console finish panel)
- Remote Functions Receiver (RFR) module (located above the headliner, near the driver side sun visor area)
- Remote Function Actuator (RFA) module (located behind the glove compartment)
- PCM (located in the engine compartment, under the RH cowl)
The PATS function is controlled by the RFA module. PATS uses the RFA module to carry out all of the PATS functions such as receiving the identification code from the IA key, sending a signal to the PCM to control the starter and fuel injectors enable, and initiating the key interrogation sequence when the ignition state is changed to ON or START.
PATS is active only for a few seconds when the vehicle is starting. It is not a PATS concern if the vehicle stalls after it has been running for a minimum of 3 seconds. PATS cannot disable a running vehicle.
The PATS function uses the RFA module and the PCM to enable or disable the engine. All elements of PATS must be functional before the engine is allowed to start. If any of the components are not working correctly, the vehicle cannot start.
PATS disables the vehicle from starting if there is:
- a damaged IA key.
- a damaged IA passive start antenna (of the 3 used for starting the vehicle).
- an unprogrammed IA key.
- a non-encoded (non-IA) key (a conventional PATS key or one that does not have any electronics).
- damaged wiring.
- a damaged backup transceiver (only if the IA key is in the backup transceiver slot).
- a dead battery in the IA key (backup transceiver slot may be used to start the vehicle in this case).
- a damaged RFR module.
- a damaged RFA module.
- a damaged PCM.
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 can cause no-start concerns. Remote start systems must be removed from the vehicle before any PATS-related no-start concerns are investigated.
Backup Transceiver
The backup transceiver is located in the rear of the floor console and its associated backup transceiver slot is located in the floor console storage compartment. This slot allows the IA key to be placed in close proximity to the backup transceiver for starting purposes. If the vehicle does not start normally, place the IA key in the backup transceiver slot and attempt to start the vehicle. If the vehicle does not start normally at this time, refer to Anti-Theft - Intelligent Access (IA) Testing and Inspection and follow the appropriate diagnostic direction. Make sure the transmitter buttons are facing forward and the key ring is up for the most efficient backup transceiver operation.
It is not recommended to leave the IA key in the backup transceiver slot, as this decreases the security of the system.
Intelligent Access (IA) with Push Button Start Ignition Modes
The IA 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.
