Passive Anti-Theft System (PATS) - Diagnostic Trouble Codes (DTC) Descriptions

WARNING: This page is about a different car, the 2006 Mercury Milan, 2006 Lincoln Zephyr, and 2006 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.

EXPANDED DIAGNOSTIC TROUBLE CODE (DTC) DESCRIPTIONS

DTC	Expanded Description
B1213	Less than 2 keys programmed to the PATS control. Use the diagnostic card to run the self-test on the PATS functions in the instrument cluster. If DTC B1600, B1601, B1602 or B1681 are present, they must be repaired first. If DTC B1213 is the only self-test DTC, then cycle the second PATS key in the ignition to program.
B1600	No PATS key read by the PATS control. This can be caused by the PATS key, PATS transceiver, circuits between the PATS transceiver and the PATS control and/or the PATS control.
B1601	Unprogrammed PATS key. There is no issue with the PATS key itself, but the key must be programmed into the PATS memory (unless the maximum number of keys are already programmed). Refer to SPARE KEY PROGRAMMING . No parts need to be replaced for this DTC.
B1602	Partial PATS key was read. Make sure that approved PATS key (Ford, Rotunda or Strattec) is being used. Large metal objects, additional PATS keys, or devices used to purchase gasoline located on the customer's key ring 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 ring. Remote starter equipment can also cause this DTC. Remove any remote starter equipment close to the transceiver before conducting further diagnosis. This DTC can be caused by the PATS key or the PATS transceiver.
B1681	PATS transceiver module signal is not received by the PATS control. This DTC can be caused by circuits between the PATS transceiver and the PATS control, the PATS transceiver or the PATS control. Follow the pinpoint test for diagnosis. This can also be caused by using the incorrect transceiver part number. Make sure that the correct transceiver part number is being used.
B2103	Transceiver module antenna failure. Incorrect or nonexistent diagnostic data from the transceiver.
B2141	NVM configuration failure. PATS does not have a stored PCM_ID in memory (PATS PID PCM_ID=not STORED). If a DTC U2511 is also present, it must be repaired first.
B2431	The key is not programmed. Make sure a correct PATS key is used. Program a new ignition key.
P1260	This DTC is stored any time the PCM disables the vehicle because of a PATS issue. Whenever the PCM stores DTC P1260, there should be PATS DTC(s) stored in the instrument cluster that require diagnosis.
