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 oft) 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 it 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.
