This TSB article is being republished in its entirety to update the model year vehicles and the diagnostic procedures.

ISSUE:

A vehicle equipped with Passive Anti-Theft System (PATS) may not start or crank. This may be caused by several different items.

ACTION:

Refer to the following PATS Diagnostic Charts and text for tips on servicing customer PATS concerns.

Glossary Of Terms

  • PATS – Passive Anti-Theft System
  • HEC – Hybrid Electronic Cluster
  • VIC – Virtual Image Cluster
  • ICM – Instrument Cluster Module
  • SCIL – Steering Column Ignition Lighting
  • CJB – Central Junction Box

NOTE:ERASING AND REPROGRAMMING THE CUSTOMER’S IGNITION KEYS DOES NOT CURE ANY KNOWN INTERMITTENT PATS NO START ISSUE. DO NOT SIMPLY REPROGRAM THE IGNITION KEYS IF A FAULT CANNOT BE IDENTIFIED.

NOTE:THE ONLY FORD QUALIFIED PATS KEYS ARE THOSE MANUFACTURED BY: FORD ROTUNDA, ILCO, STRATTEC, HUF, AND VALEO.

ONLY FORD ROTUNDA KEYS ARE QUALIFIED FOR THE FOLLOWING PROGRAMS:

  • 2000 AND 2001 TAURUS/SABLE
  • 2001 WINDSTAR
  • 2001 EXPLORER SPORT (BUILT AFTER JULY 24, 2000)
  • 2001 EXPLORER SPORT TRAC (BUILT AFTER JULY 24, 2000)
  • 2001 RANGER (3.0L AND 4.0L)
  • 2001 ESCAPE
  • 2002 EXPLORER
OTHER AFTERMARKET KEYS ARE NOT FORD QUALIFIED AND CAN CAUSE PATS ISSUES.

NOTE:DIAGNOSTIC TROUBLE CODE (DTC) P1260 IN THE POWERTRAIN CONTROL MODULE (PCM) IS A DIRECTION TO RETRIEVE FAULT CODES FROM PATS. RETRIEVE FAULT CODES FROM THE APPROPRIATE PATS FUNCTION (PATS/HEC/VIC/ICM/SCIL) AND FOLLOW THOSE PINPOINT PROCEDURES BEFORE ANY FURTHER PCM DIAGNOSIS.

NOTE:VEHICLES WITH PATS TYPE A, B, OR C SEND AN ENABLE MESSAGE TO THE PCM IF THE PROPER CONDITIONS ARE MET. THE PCM THEN ALLOWS FUEL INJECTOR AND FUEL PUMP OPERATION. THE PROPER CONDITIONS ARE: 1) A VALID KEY READ FOR PATS TYPES A, B, AND C, AND 2) PROPER PATS-PCM INITIALIZATION FOR PATS TYPES B AND C. REFER TO CHART FOR DETAILS ON THE REQUIRED INITIALIZATION.

NOTE:SOME VEHICLES WITH PATS TYPE B OR C MAY INCLUDE A STARTER INTERRUPT (SI). THESE VEHICLES DO NOT NECESSARILY HAVE TO EXHIBIT A NO CRANK SITUATION TO CONSTITUTE A PATS RELATED NO START.

NOTE:CHECK FOR A REMOTE VEHICLE STARTER AND REMOVE ANY SUCH EQUIPMENT FROM THE VEHICLE BEFORE CONTINUING DIAGNOSIS.

NOTE:SOME AFTERMARKET AUDIO EQUIPMENT HAS BEEN FOUND TO KEEP THE RUN/START CIRCUIT ACTIVE FOR OVER 5 SECONDS PAST IGNITION OFF. THIS CAN PREVENT PATS FROM PROPERLY READING IGNITION KEYS DURING KEY PROGRAMMING. REMOVE OR DISABLE THIS AFTERMARKET EQUIPMENT IF PROBLEMS WITH ANY KEY PROGRAMMING SEQUENCE OCCUR.

NOTE:WHEN USING THE SERVICE CARD, SELECT ONLY THE FUNCTIONS MENTIONED WITH THE PROCEDURE. SELECTING INCORRECT FUNCTIONS (OR ADDITIONAL UNCALLED FOR FUNCTIONS) MAY RESULT IN A NO START CONDITION AND THE NEED FOR FURTHER DIAGNOSIS AND REPAIR.

NOTE:REPROGRAMMING OF THE PCM DOES NOT HAVE ANY IMPACT ON PATS IF THE PROCEDURE FUNCTIONS AS INTENDED.

NOTE:IF THE VEHICLE DOES NOT START AND THERE IS NORMAL PROVE-OUT OF THE THEFT INDICATOR AND DTC P1260 IS NOT STORED IN THE PCM, THEN THE VEHICLE HAS A NON-PATS RELATED ISSUE PREVENTING THE VEHICLE FROM STARTING.

NOTE:IF THE VEHICLE (SYSTEM TYPES A, B, C, D ONLY) IS A NO START WITH THE THEFT LIGHT FLASHING AT IGNITION ON, AND WITH NO DTC P1260 STORED IN THE PCM, CHECK PCM POWER, GROUND, AND VREF CIRCUITS FOR OPENS OR SHORTS. THE PCM MAY NOT BE OPERATING PROPERLY.

NOTE:IF THE ENGINE DOES NOT CRANK ON VEHICLES THAT HAVE PATS OPERATING THE STARTER RELAY, VERIFY PATS (PATS/ICM/SCIL) OUTPUT TO THE STARTER RELAY. ALSO VERIFY THE PATS POWER AND GROUND CIRCUITS.

NOTE:BE AWARE THAT THE NEW PATS SYSTEM TYPES B, C, AND E (ON THE FOLLOWING CHART) OFFER AN ANTI-SCAN FEATURE. IF YOU ARE TRYING TO START A VEHICLE WITH AN UNPROGRAMMED PATS KEY, THE THEFT LIGHT EMITTING DIODE (LED) WILL FLASH RAPIDLY AND THE VEHICLE WILL NOT BE ABLE TO START. IN THIS CASE, LEAVE THE KEY IN THE RUN/START POSITION FOR 30 SECONDS FOR THE ANTI-SCAN FEATURE TO TIME OUT. IF THIS TIME-OUT IS NOT COMPLETED, THE VEHICLE WILL CONTINUE TO NOT START WITH EVEN A PROGRAMMED KEY.

NOTE:AFTER PERFORMING A KEY ERASE PROCEDURE ON A TYPE “E” SYSTEM, DISCONNECT THE DIAGNOSTIC TOOL AND LEAVE IGNITION IN RUN FOR 10 SECONDS. THEN TURN IGNITION OFF AND ADD KEYS.

NOTE:FORD CUSTOMER SERVICE DIVISION (FCSD) DEALER INSTALLED REMOTE STARTER SYSTEMS ARE APPROVED FOR USE ON FORD VEHICLES.

NOTE:WHEN REPLACING THE PCM ON A 2000 OR 2001 LINCOLN LS V6 MANUAL TRANSMISSION VEHICLE, ALSO PERFORM A PARAMETER RESET TO THE STEERING COLUMN LOCK MODULE PER THE WORKSHOP MANUAL, SECTION 211-05.

NOTE:WHEN REPLACING AN INSTRUMENT CLUSTER ON A 2000 OR 2001 LINCOLN LS BE SURE TO DISCONNECT THE VEHICLE BATTERY. FAILURE TO DISCONNECT THE BATTERY MAY RESULT IN SHORTING THE PATS TRANSCEIVER UPON REPLACING THE INSTRUMENT CLUSTER. THIS WILL RESULT IN BLOWING FUSE #224 IN THE CJB. WHEN THIS FUSE IS BLOWN, A NO START SITUATION WILL OCCUR AND A B1681 PATS CODE STORED.
