No where in the DTC - description does it say anything about replacing any modules . An does not have anything to do with a communication problem ! You need a professional grade scan tool to communicate with the PATS system ! An if you don't know these thing's you better take it to pro !!!!!!!
P1260 - Theft Detected - Vehicle Immobilized Indicates that the passive anti-theft system (PATS) has determined a theft condition existed and the engine is disabled. This DTC is a good indicator to check the PATS for DTCs.

  • Previous theft condition
  • Anti-Theft System failure
Theft indicator flashing rapidly or on solid when ignition switch is in the ON position. Check anti-theft system for DTCs. Typical vehicle symptoms are: Start/Stall or Crank/No Start. NOTE: No crank symptom only on vehicles equipped with PATS starter disable feature

Where is the PATS module on 2008 Ford F350?


Passive Anti-Theft System (PATS) Transceiver Is behind the steering column shroud . It's around where the ignition lock cylinder is ! There is no PATS module ! The PATS function is controlled by the instrument cluster. The PATS uses the instrument cluster 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 initiates the key interrogation sequence when the ignition key is turned to the ON or START position. Because of the interaction between the instrument cluster and the PCM, there are parameters that must be reset if the instrument cluster or the PCM (or both) is replaced. For additional information, refer to Passive Anti-Theft System (PATS) Parameter Reset in this section. If the instrument cluster must be replaced for any reason (PATS concerns or instrument cluster concerns), the PATS keys also must be programmed into the new instrument cluster. For additional information, refer to Key Programming Using Diagnostic Equipment in this section. All elements of PATS must be functional before the vehicle will start. If any of the components are not working correctly, the vehicle will not start. Your best bet , take it to the dealer !

What will cause a 1999 Pontiac Sunfire to not go into the extended learn mode when replacing the ign lock assembly .


Did you clear codes ? . All codes in the theft deterrent module must be cleared for a relearn.
PASSLOCK Changing - Components Description
Important: Due to component variability, the vehicle theft deterrent (VTD) system must have the learn procedure performed regardless, if the vehicle starts on the first ignition cycle after a VTD repair.
All codes in the theft deterrent module must be cleared for a relearn.
Engineers design the Passlock™ system in order to prevent theft even if the various theft deterrent parts change. The Tamper mode will engage if any of the following components change:
• The Passlock™ lock cylinder
• The instrument cluster
• The powertrain control module (PCM)
If you replace any of the above components, the system will enter the long tamper mode. If the system enters the long tamper mode, ensure that the system completes a long tamper mode cycle. During the long tamper mode cycle, the THEFT indicator will flash for the full 10 minutes. The instrument cluster and the PCM require the full 10 minutes in order to complete the learn cycle. Ensure that the ignition switch remains in RUN until the indicator stops flashing. If you turn the ignition switch before the indicator stops flashing, repeat the long tamper cycle from the beginning.
Are there any codes ?
Problem
Action
The THEFT SYSTEM indicator will not light under any circumstances.

SECTION 419-01: Anti-Theft - PATS 2002 F-150 Workshop Manual
DESCRIPTION AND OPERATION Anti-Theft -PATS The passive anti-theft system (PATS) contains the following components:
  • theft indicator
  • encoded ignition key
  • transceiver module
  • instrument cluster
  • powertrain control module (PCM)
  • standard corporate protocol (SCP) communication network
The PATS uses radio frequency identification technology to deter a driveaway theft. Passive means that it does not require any activity from the user. This system is known as SecuriLock® in North America, Safeguard® in the U.K. and PATS in continental Europe. This information can be found in owners literature.
The PATS uses a specially encoded ignition key. Each encoded ignition key contains a permanently installed electronic device called a transponder. Each transponder contains a unique electronic identification code, with over 72 million billion combinations.
Each encoded ignition key must be programmed into the vehicle's instrument cluster (the instrument cluster is also known as a hybrid electronic cluster [HEC]), before it can be used to start the engine. There are special diagnostic procedures outlined in the workshop manual that must be carried out if new encoded ignition keys are to be installed.
The encoded key is larger than a traditional ignition key. The key does not require batteries and should last the life of the vehicle.
The transceiver module communicates with the encoded ignition key. This module is located behind the steering column shroud and contains an antenna connected to a small electronics module. During each vehicle start sequence, the transceiver module reads the encoded ignition key identification code and sends the data to the instrument cluster.
The control functions are contained in the instrument cluster. This module carries out all of the PATS functions such as receiving the identification code from the encoded ignition key and controlling engine enable. The instrument cluster initiates the key interrogation sequence when the vehicle ignition switch is turned to RUN or START.
The PATS uses the PCM to enable or disable the engine. The instrument cluster communicates with the PCM over the SCP network in order to enable engine operation. The instrument cluster and the PCM use sophisticated messages in order to prevent a theft. The instrument cluster and the PCM share security data (when first installed together) that makes them a matched pair. After this security data sharing, these modules will not function in other vehicles. The shared PCM ID is remembered even if the battery is disconnected. The instrument cluster also stores the vehicle's key identification code even if the battery is disconnected. There are special diagnostic procedures outlined in this workshop manual that may be carried out if either a new instrument cluster or PCM needs to be installed.
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 will not start.
PATS uses a visual theft indicator. This indicator will prove out for three seconds when the ignition switch is turned to RUN or START under normal operation. If there is a PATS problem, this indicator will either flash rapidly or glow steadily (for more than three seconds) when the ignition switch is turned to RUN or START. PATS also "blips" the theft indicator every two seconds at ignition OFF to act as a visual theft deterrent.
The PATS is not compatible with aftermarket remote start systems, which allow the vehicle to be started from outside the vehicle. These systems may reduce the vehicle security level, and also may cause no-start issues. Remote start systems must be removed before investigation of PATS-related no-start issues.

Your key has to be able to communicate with the receiver in the ignition area. Does your other key work ok?

Anti-Theft The passive anti-theft system (PATS) uses radio frequency identification technology to deter a driveaway theft. Passive means that it does not require any activity from the user.
  • During each vehicle start sequence, the ignition key identification code is requested by the PATS module.
  • If the key's ID code has been programmed into the system, the vehicle powertrain control module (PCM) (12A650) is allowed to operate; this allows the vehicle to start.
  • If the key's ID code is not programmed into the PATS module, or if no encoded key is detected, then the vehicle PCM is disabled.
The PATS module, located under the driver side instrument panel, communicates the state of the security system to the PCM via the module communications network. The PCM, based on the communications from the PATS module, will determine if the vehicle's engine will be enabled to start. If the PCM prevents the vehicle from starting because of PATS, the PCM will store a DTC in memory.
-------------------------------------------------------------------------
The anti-theft vehicle protection system utilizes the THEFT indicator, located in the instrument cluster (10849), when the ignition switch is turned to the RUN/START position. The indicator provides system prove out and operating status to the customer or technician.
Each PATS ignition key holds electronics that give each key a unique ID code.
The PATS will activate the indicator signal when the ignition switch is turned to the RUN/START position. The THEFT indicator will turn ON for two seconds, then turn OFF.
If the THEFT indicator flashes for one minute or more, this indicates that there was no key code received.
When the vehicle ignition switch is placed in either RUN or START, the PATS module requests the ignition key ID code. The PATS module requests the ignition key ID code by supplying power, ground, and the carrier signal to the transceiver to energize the ignition key. After the energize period, the key transmits its ID code to the transceiver module, which sends it to the PATS module.
The PATS module then compares the received KEY ID code to those stored in memory (16 maximum). If the ID matches, the PATS module sends an enable signal to the PCM over the module communication network.
The passive vehicle protection system utilizes the engine management capabilities of the PCM to enable or disable the vehicle engine. The module communication network is used to send and receive messages to and from the PCM.
Within one second after engine start, the PCM must receive an enable signal from the PATS module through the module communication network or the engine is disabled before the vehicle can be moved.
If the PATS module recognizes a stored ignition key code but there is a module communication network concern preventing the PCM from recognizing the start enable signal from the PATS module, the vehicle engine will be disabled. If this happens, the PATS module will flash the THEFT indicator for one minute, then flash diagnostic trouble code 16 ten times to indicate there is a problem with the module communication network circuits or the PCM is not responding properly.
The passive vehicle protection system will disable the vehicle from starting if there is a:
  • Damaged encoded key.
  • Unprogrammed key.
  • Non-encoded key (key has no electronics).
  • Wiring concern.
  • Transceiver concern.
  • Control module concern.
  • Module communications network concern.

98 lincoln town car wont start, the theft protection is activated


theft protection rsets itself. I have never seen a PCM go bad. Some just need a reflash which costs much, much less. You can get a used PCM if you really think you need one, at car-part.com. Page with asterisk is lowest price.

here's some info on antitheft. What's your red light doing on the dash when you turn on the key or try to start the car?

The passive anti-theft system (PATS) also contains the following components:
  • Theft indicator.
  • Encoded ignition key.
  • Passive anti-theft transceiver module.
  • Hybrid electronic cluster (HEC).
  • Powertrain control module.
  • J1850 communication network.
  • Lighting control module (LCM).
The passive anti-theft system (PATS) uses radio frequency identification technology to deter a driveaway theft. Passive means that it does not require any activity from the user. This system is known as SecuriLock® in North America, Safeguard® in the U.K., and PATS in Continental Europe. This information can be found in customer literature such as the Owner's Manual.
PATS uses a specially encoded ignition key. Each encoded ignition key contains a permanently installed electronic device called a transponder. Each transponder contains a unique electronic identification code out of over 72 million billion combinations.
Each encoded ignition key must be programmed into a vehicle's hybrid electronic cluster (HEC) before it can be used to start the engine. There are special diagnostic service procedures outlined in the workshop manual that must be performed if the encoded ignition keys need to be replaced.

The HEC also stores the vehicle's key identification code even if the battery is disconnected. There are special diagnostic workshop procedures outlined in this service manual that may be performed if either the HEC or the PCM needs replacement.
All elements of PATS must be functional before the engine is allowed to start. If any of the components are not working properly, the vehicle will not start.

If there is a PATS problem, this indictor will either flash rapidly or glow steadily (more than three seconds) when the ignition switch is turned to RUN or START. PATS also "blips" the theft indicator every two seconds at ignition OFF to act as a visual theft deterrent.
PATS differs from the perimeter anti-theft system in that PATS enables and disables the engine from starting. If equipped, the perimeter anti-theft system protects the perimeter of the vehicle (doors, hood, and trunk) and sounds an alarm.

The PATS uses the PCM to enable or disable the engine. The instrument cluster communicates with the PCM over the SCP network in order to enable engine operation. The instrument cluster and the PCM use sophisticated messages in order to prevent a theft. The instrument cluster and the PCM share security data (when first installed together) that makes them a matched pair. After this security data sharing, these modules will not function in other vehicles. The shared PCM ID is remembered even if the battery is disconnected. The instrument cluster also stores the vehicle's key identification code even if the battery is disconnected. There are special diagnostic procedures outlined in this workshop manual that may be carried out if either a new instrument cluster or PCM needs to be installed.
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 will not start.
PATS uses a visual theft indicator. This indicator will prove out for three seconds when the ignition switch is turned to RUN or START under normal operation. If there is a PATS problem, this indicator will either flash rapidly or glow steadily (for more than three seconds) when the ignition switch is turned to RUN or START. PATS also "blips" the theft indicator every two seconds at ignition OFF to act as a visual theft deterrent.
The PATS is not compatible with aftermarket remote start systems, which allow the vehicle to be started from outside the vehicle. These systems may reduce the vehicle security level, and also may cause no-start issues. Remote start systems must be removed before investigation of PATS-related no-start issues.

  • Instrument cluster.
  • Theft indicator.
  • GO to Pinpoint Test B .
  • The vehicle does not start — theft indicator proves out for three seconds as normal
  • Less than two keys programmed to the system.
  • Transceiver not connected/defective.
  • Circuitry.
  • Transceiver internal antenna damaged.
  • NON-PATS key, damaged key or no code received.
  • Partial key read of PATS key.
  • Unprogrammed PATS key.
  • PERFORM instrument cluster on-demand self-test. RETRIEVE DTCs. If DTCs are present, GO to Instrument Cluster Diagnostics Trouble Code (DTC) Index. If no DTCs are retrieved, CHECK for other possible no-start causes.
  • No PCM ID stored in PATS.
  • PATS/PCM ID do not match.
  • Problem with SCP link.
  • CLEAR the stored DTCs. CYCLE the ignition key from off to run. RETRIEVE continuous DTCs. If DTCs are present, GO to Instrument Cluster Diagnostics Trouble Code (DTC) Index. If no DTCs are retrieved, CHECK for other possible causes.
  • The alarm system does not operate properly — the vehicle starts but flashes a fault code on theft indicator at key on
  • Incorrect PCM calibration.
  • GO to Pinpoint Test C .

--- Key Programming —Program a Key Using Two Programmed Keys NOTE: This procedure only works if two or more programmed ignition keys are available and it is desired to program additional key(s). If two keys are not available, follow the procedure in Key Programming—Erase All Key Codes and Program Two Keys .
NOTE: PID SPARE_KY must be enabled for this procedure to operate. If this Parameter Identification (PID) Index is not enabled, follow the security access procedure and select Spare Key Programming Switch: Enabled.
NOTE: If the programming procedure is successful, the new key(s) will start the vehicle and the THEFT INDICATOR will illuminate for approximately three seconds.
NOTE: If the programming procedure is not successful, the new key(s) will not start the vehicle and the THEFT INDICATOR will flash. If the programming procedure was not successful, repeat the key programming procedure from Step 1. If the failure repeats, check Circuit 729 (RD/WH) (hot at all times) in instrument cluster for proper battery voltage. Repair the circuit if voltage is not present. For additional information, refer to Diagnosis and Testing to review diagnostic trouble codes (DTCs) and perform pinpoint tests as required.
NOTE: A maximum of eight ignition keys can be programmed to a passive anti-theft system (PATS) equipped vehicle. Use PID NUMKEYS to determine how many keys are programmed to the vehicle.
NOTE: If the steps are not performed as outlined, the programming procedure will end.
NOTE: Ignition keys must have correct mechanical key cut for the vehicle and must be a PATS encoded key.
  1. Insert the first programmed ignition key into the ignition lock cylinder and turn the ignition switch from OFF to RUN (maintain the ignition switch in RUN for one second).
  1. Turn the ignition switch to OFF and remove the first key from the ignition lock cylinder.
  1. Within five seconds of turning the ignition switch to OFF, insert the second programmed ignition key into the ignition lock cylinder and turn the ignition switch from OFF to RUN (maintain the ignition switch in RUN for one second).
  1. Turn the ignition switch to OFF and remove the second key from the ignition lock cylinder.
  1. Within 10 seconds of turning the ignition lock cylinder to OFF, insert the unprogrammed ignition key (new key) into the ignition lock cylinder and turn the ignition switch from OFF to RUN (maintain the ignition switch in RUN for 1 seconds

Is there any way eliminate the anti-theft system on my 1999 windstar cause mine is malfunctioning and not allowing it to run (start). How many parts and connectors make up the system,anyways?


Anti-Theft —Passive The passive anti-theft system (PATS) contains the following components:

  • theft indicator
  • encoded ignition key
  • transceiver module
  • instrument cluster
  • powertrain control module (PCM)
  • standard corporate protocol (SCP) communication network
  • starter relay
The PATS uses radio frequency identification technology to deter a driveaway theft. Passive means that it does not require any activity from the user. This system is known as SecuriLock® in North America, Safeguard® in the U.K. and PATS in continental Europe. This information can be found in customer literature such as the Owners Guide.
The PATS uses a specially encoded ignition key. Each encoded ignition key contains a permanently installed electronic device called a transponder. Each transponder contains a unique electronic identification code, with over 72 million billion combinations.
Each encoded ignition key must be programmed into the vehicle's instrument cluster before it can be used to start the engine. There are special diagnostic procedures outlined in the manual that must be performed if the encoded ignition keys need to be replaced.
The encoded key is larger than a traditional ignition key. The key does not require batteries and should last the life of the vehicle.
The transceiver module communicates with the encoded ignition key. This module is located behind the steering column shroud and contains an antenna connected to a small electronics module. During each vehicle start sequence, the transceiver module reads the encoded ignition key identification code and sends the data to the instrument cluster.
The control functions are contained in the instrument cluster. This module performs all of the PATS functions such as receiving the identification code from the encoded ignition key and controlling the engine enable. The instrument cluster initiates the key interrogation sequence when the vehicle ignition switch is turned to RUN or START.
The PATS uses the PCM to enable or disable the engine. The instrument cluster communicates with the PCM over the SCP communication network in order to enable engine operation. The instrument cluster and the PCM use sophisticated messages in order to prevent a theft. The instrument cluster and the PCM share security data when first installed together that makes them a matched pair. After this security data sharing, these modules will not function in other vehicles. The shared PCM ID is remembered even if the battery is disconnected. The instrument cluster also stores the vehicle's key identification code even if the battery is disconnected. There are special diagnostic procedures outlined in this workshop manual that may be performed if either the instrument cluster or the PCM needs replacement.
All elements of PATS must be functional before the engine is allowed to start. If any of the components are not working properly, the vehicle will not start.
PATS uses a visual theft indicator. This indicator will prove out for three seconds when the ignition switch is turned to RUN or START under normal operation. If there is a PATS problem, this indicator will either flash rapidly or glow steadily (for more than three seconds) when the ignition switch is turned to RUN or START. PATS also "blips" the theft indicator every two seconds at ignition OFF to act as a visual theft deterrent.
PATS differs from perimeter anti-theft systems in that PATS enables and disables the engine from starting. If equipped, the perimeter anti-theft system protects the perimeter of the vehicle (doors, hood and trunk) and sounds an alarm.
PATS also disables the starter motor in addition to the PCM disabling the engine. When PATS disables the vehicle, it will neither crank nor start. If the instrument cluster is removed from the vehicle, the engine will not crank.
The starter relay is used as an additional means of disabling the vehicle engine. The starter relay is disabled when the PATS cannot read a valid encoded ignition key at ignition ON. The PATS will not store a diagnostic trouble code (DTC) or flash the theft indicator if a valid encoded ignition key is read but a fault occurs in the starter relay circuit.
The PATS is not compatible with after market remote start system, which allow the vehicle to be started from outside the vehicle. These systems may reduce the vehicle security level, and also may cause no-start issues. Remote start systems must be removed before investigation of PATS-related no start issues.
