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.

CLARIFICATION ON SELECTED DTCs

Utilize the pinpoint testing found in the appropriate Workshop Manual for proper troubleshooting. Refer to the following for supplemental pinpoint details.

DTCs Stored in PATS Control (PATS/VIC/HEC/SCIL/ICM)

B1213: Less than two (2) keys programmed to the PATS control. Use Diagnostic Card to run self test on PATS (or VIC/HEC/SCIL). If DTCs B1232, B1600, B1601, B1602, or B1681 are present, they must be serviced first. If B1213 is the only self test DTC, then cycle second PATS key in ignition to program.
B1232/B2103: Transceiver module antenna failure. Replace transceiver module.
B1600: No PATS key read by the PATS control. This can be caused by the PATS key, PATS transceiver, circuits between the PATS transceiver/PATS control, and/or the PATS control. For 1996-1997 Taurus Sable, 1996-1997 Mustang, and 1997-1998 Expedition/Navigator, overlay all wires from transceiver pigtail harness to control module if an intermittent failure cannot be corrected by replacing transceiver module.

B1601: Unprogrammed PATS key. There is no issue with the PATS key itself, but must be programmed into the PATS memory (unless maximum number of keys already programmed). Follow Spare Key Programming Procedure from the chart. No parts should need to be replaced for this code.
B1602: Partial PATS key was read. Verify that approved PATS key (Ford Rotunda, ILCO, Strattec, HUF, or Valeo) is being used. Large metal objects, additional PATS keys, or devices to purchase gasoline located on the customer's key chain can cause interference. Instruct the customer to keep such items from touching the ignition key during engine start. It is not necessary to remove the objects from the customer's key chain. Remote starter equipment can also cause this fault code. Remove any remote starter equipment close to the transceiver before conducting further diagnosis. This DTC can be caused by the PATS key or PATS transceiver.
B1681: PATS transceiver module signal is not received by the PATS control. This code can be caused by circuits between PATS transceiver and PATS control, PATS transceiver, or possibly the PATS control. Follow pinpoint test for troubleshooting. This can also be caused by using the wrong transceiver part number. Verify the correct transceiver part number is being used.
B2139: The PCM_ID does not match between the PCM and PATS (VIC/HEC/ICM). Using Service Card, select Service Bay Functions, PATS (VIC/HEC/ICM), enter Security Access (10 minute delay), Parameter Reset. Then using the Diagnostic Card, select: PCM, Active Commands, Keep Alive Memory Reset. Cancel back to the previous NGS screen. Turn ignition OFF. Then disconnect the DLC. Cycle ignition 3 times slowly (3 seconds ON, 3 seconds OFF) to re-initialize the system.

B2141: NVM configuration failure. This means PATS does not have a stored PCM_ID in memory (PATS PID PCM_ID = not STORED). If DTC U1147 is also present, it must be fixed first. Attempt to fix a U1262 first as well, but it may not be required to fix this fault prior to the B2141. If B2141 is the only DTC, then using Diagnostic Card, select: PCM, Active Commands, Keep Alive Memory Reset. Cancel back to the previous NGS screen. Turn ignition off. Then disconnect the DLC. Cycle ignition 3 times slowly (3 seconds on, 3 seconds off) to re-initialize the system.
U1147: This code indicates a communication issue (Bus+, Bus-) between the PCM and PATS (VIC/HEC/SCIL). This code CANNOT be caused by PATS key, PATS transceiver, or the circuits between PATS transceiver and PATS control. Whenever PATS has U1147 as a stored DTC, there should be a "P1260 Theft Detected - Engine Disabled" in the PCM stored codes. Verify that P1260 is stored in PCM. If not, there is a possible power-up issue of the PCM (i.e., PATS is powering up at key to RUN/START but the PCM is not, therefore when PATS tries to communicate over Circuits 914 and 915 to the PCM, there is no response); verify power and ground circuits to the PCM; verify the tester can communicate with the PCM.
U1262: This code indicates a communication issue (Bus+, Bus-) between the PATS/HEC/ICM and some other module. Do not perform PATS diagnostics if a no start is not reported of if theft indicator is not flashing rapidly at ignition RUN position. If the indicator is flashing, check to make sure the PCM is powered up and operating. If it's not, continue with PCM diagnostics.
B2431: The ignition key (used on 2000 LS) was not programmed. Note that this vehicle has a special ignition key. Replace ignition key, using the correct style. If the fault persists, replace the transceiver module.

DTCs Stored in PCM (that are related to PATS)

System Types A, B, C, and D only

P1260: This code will be stored any time the PCM disables the vehicle because of the PATS system. Whenever the PCM has a stored P1260, there should be stored DTCs in PATS that require troubleshooting.

System Type E only

B1213: Less than two (2) keys programmed to the PATS control. Erase continuous codes, cycle ignition, then retrieve continuous fault codes again. If DTCs B1232, B1600, B1601, B1602, or B1681 are present, they must be serviced first. If B1213 is the only PATS related code stored, then cycle second PATS key in ignition to program.
B1342: Electronic Control Unit (ECU) defective. Memory failure in PCM. Replace PCM.
B1600: No PATS key read by the PCM. This can be caused by the PATS key, PATS transceiver, circuits between the PATS transceiver/PCM, and/or the PCM.
B1601: Unprogrammed PATS key. There is no issue with the PATS key itself, but must be programmed into the PATS memory (unless maximum number of keys already programmed). Follow Spare Key Programming Procedure from the chart. No parts should need to be replaced for this code.
B1602: Partial PATS key was read. Verify that approved PATS key (Ford Rotunda, ILCO, Strattec, HUF, or Valeo) is being used. Large metal objects, additional PATS keys, or devices to purchase gasoline located on the customer's key chain can cause interference. Instruct the customer to keep such items from touching the ignition key during engine start. It is not necessary to remove the objects from the customer's key chain. Remote starter equipment can also cause this fault code. Remove any remote starter equipment close to the transceiver before conducting further diagnosis. This DTC can be caused by the PATS key or PATS transceiver.
B1681: PATS transceiver module signal is not received by the PCM. This code can be caused by circuits between PATS transceiver and PCM, PATS transceiver, or possibly the PCM. Follow pinpoint test for troubleshooting. This can also be caused by using the wrong transceiver part number. Verify the correct transceiver part number is being used.
B2103: Transceiver module antenna failure. Replace transceiver module.
B2431: The ignition key was not programmed. Reference the ROTUNDA KEY SELECTION CHART WITH PART NUMBERS elsewhere in this TSB to verify that you are using the correct key.
