Anti-Theft - Passive Anti-Theft System (PATS)
Anti-Theft
The Passive Anti-Theft System (PATS) consists of the following components:
- Anti-theft indicator (located in the Instrument Cluster (IC))
- Encoded ignition Integrated Keyhead Transmitter (IKT) PATS key(s) (the key contains a transponder and a Remote Keyless Entry (RKE) transmitter)
- PATS transceiver (located at the ignition lock cylinder under the steering column shroud)
- IC
- PCM (located in the bulkhead)
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 2 IKT PATS keys. The IKTs operate as a standard PATS key with an RKE transmitter incorporated into the keyhead. The IKTs require batteries for the RKE transmitter to operate. 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 does not operate. These additional keys start the vehicle, but do not 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.
Passive Anti-Theft System (PATS) Function
The PATS function is controlled by the IC. PATS uses the IC to carry out all of the PATS functions such as receiving the identification code from the PATS key, issuing a signal to the PCM to control the starter and fuel injectors enable, and initiating the key interrogation sequence when the ignition key is turned to the ON or START position. Because of the interaction between the IC and the PCM, there are parameters that must be set if the IC or the PCM (or both) are replaced. Refer to Passive Anti-Theft System (PATS) Parameter Reset Passive Anti-Theft System (PATS) Parameter Reset. If the IC must be replaced for any reason (PATS concerns or IC concerns), the PATS keys also must be programmed into the new IC. Refer to Integrated Keyhead Transmitter (IKT) Key Programming Using Diagnostic Equipment Integrated Keyhead Transmitter (IKT) Key Programming Using Diagnostic Equipment. All elements of PATS must be functional before the vehicle starts. If any of the components are not working correctly, the vehicle does not 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 does not disable a running vehicle.
The PATS may cause a vehicle no start due to either the fuel injectors not operating or the starter not operating (starter relay does not close) or both.
PATS is not compatible with aftermarket remote start systems, which allow the vehicle to be started from the exterior of the vehicle. These systems may reduce the security of the vehicle, and also may be the cause of no-start concerns. Remote start systems must be removed from the vehicle before any PATS-related no-start concerns are investigated. If the remote start system is a Power Code(TM) system, make certain it is not the cause of the no-start. Removal of the system may be necessary.
Factory Invoiced Accessory (FIA) Remote Starter
Vehicles may be equipped with a dealer-installed factory-invoiced 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 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 IC. The remote start system uses up 1 of the 8 total PATS keys that can be programmed into the IC. The number of keys that are programmed into the PATS can be determined by viewing the IC PID N_KEYCODE.
Unlimited Key Mode
PATS contains a feature called unlimited key mode. 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 key code. This allows all the customer vehicles to share the same mechanically cut keys. For an individual customer, any security key that has been previously mechanically cut and electronically programmed to the vehicle is acceptable.
If unlimited key mode is enabled or disabled, 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, 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 Spare Key Programming - Unlimited Key Mode.
If the unlimited key mode is turned on, the MyKey(TM) feature does not function.
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) 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 IC does not allow the last admin key to be programmed into a MyKey(TM) restricted key. The admin key can be used to see how many MyKeys(TM) and admin 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 Settings
- NOTE: The standard settings below cannot be configured in any way, they can only be programmed on or disabled.
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 cannot be turned off.
Optional Settings
- NOTE: The optional settings below can be configured to the customer preferences.
The audio system volume can be programmed to limit the maximum volume to a pre-determined level (45%).
- 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.
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.
