DIAGNOSTIC TROUBLE CODE DESCRIPTIONS
DTC B1213
Description
Less than 2 (or 3 if equipped w/Valet key) keys programmed to the system.
Transceiver internal antenna damaged. Replace transceiver.
ECU is defective (EEPROM in PCM is not working - replace PCM). PATS related when stored in PCM only.
Non-PATS Key or damaged key.
Unprogrammed encoded ignition key detected (leave ignition on for 20 seconds before trying a programmed key, in Anti-Scan Mode).
Partial detection of encoded ignition key. Transceiver signal not detected.
Non-Volatile Memory (NVM) configuration failure - No PCM ID stored in PATS.
PCM ID does not match between the PCM and PATS control (PATS/ICM/VIC/HEC/SCIL).
Key program failure (defective key or transceiver).
Communications issue, SCP (J1850), between PCM and PATS control (PATS/ICM/ VIC/HEC/SCIL).
Communications issue, CAN (J2284), between PCM and PATS control (ICM).
PCM disabled the vehicle because of a PATS concern. Retrieve DTCs from applicable PATS control function (PATS/ICM/VIC/HEC/SCIL).

The following are NOT Passive Anti-Theft System issues: : ? The "Service Engine Soon" light is illuminated. (Investigate PCM system).
? There is no communication with PCM: PCM will always communicate on the diagnostic link regardless of theft status. (Investigate PCM system).
? Engine stalls on road: Once the engine runs for one second, PATS CANNOT disable the engine. Running stalls are not PATS related issues.
? Remote Entry/Keyless Entry problems: PATS is completely separate from the Remote Entry/Keyless Entry systems.
? There is a no-crank problem on vehicles without PATS Starter disable. Check chart, on reverse side, for presence of Starter Interrupt.
? PATS Theft Indicator flashes every 2 seconds at Ignition OFF. This is normal operation for PATS to act as a visual theft deterrent. See PASSIVE ANTI-THEFT SYSTEM (PATS)
SPECIFICATIONS for applicable system.
? PATS Theft Indicator stays on for 2 or 3 seconds (depending on system type) at Ignition RUN or START and then off: This is normal operation for PATS proveout on all vehicles except LS
and Thunderbird.
THINGS TO DO: ? Review Service Procedures and Technical Service Bulletins (TSBs) for latest information.
? Disconnect the diagnostic tool for 20 seconds before cycling ignition to OFF, ACC, or RUN. ? When replacing ignition keys, make sure the owner throws out ALL old keys.
? Disconnect battery cables when replacing PATS module, ICM, VIC, HEC, SCIL, PCM, or EEC.
? Look for fault codes in PATS. The PATS function will store fault codes when the PCM records a P1260.
? Be certain of the vehicle model year. Use only parts and keys specified for the appropriate model year.
? Check to make sure the issue is not with multiple PATS keys, small electronic devices that can be used to purchase gasoline, or other items on same key ring.
? Check to ensure vehicle does not have an aftermarket remote starter. Disable any Remote Starter equipment, especially anything nearby the PATS Transceiver. Ford FCSD Dealer
installed Remote Starter systems are approved for use in Ford vehicles.
? Check to ensure vehicle does not have an aftermarket engine immobilizer. The Ford FCSD aftermarket remote entry system comes with a starter interrupt that should be disabled on
PATS equipped vehicles.
? If the Alarm sounds when the ignition is turned to RUN or START, refer to the appropriate PERIMETER ALARM article.

THINGS NOT TO DO: ? Do not use aftermarket keys that are NOT Ford qualified.
? Do not reprogram keys unless a defective key or control function has been replaced. Reprogramming keys does not fix any known problem by itself.
? Do not perform more Security Access functions than required: Perform only the functions specified in the appropriate service information for this repair. Selection of extra functions may
continue the no-crank condition.
