Expanded Passive DTCS Descriptions
EXPANDED PASSIVE - DIAGNOSTIC TROUBLE CODE (DTC) LIST
| DTC | Expanded Description |
|---|---|
| B1213 | Less than two keys programmed to the PATS control. Erase the continuous codes, cycle the ignition, then carry out the self test again. If DTC B1232, B1600, B1601, B1602 or B1681 are present, they must be serviced first. If DTC B1213 is the only self test DTC, then cycle the second PATS key in the ignition to program. |
| B1232 | Transceiver module antenna failure. Memory failure in the PCM. |
| B1600 | No PATS key read by the PCM. This can be caused by the PATS key, PATS transceiver, circuits between the PATS transceiver and the PCM and/or the PCM. |
| 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, ILCO, Strattec, HUF or Valeo) 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 PCM. This DTC can be caused by circuits between the PATS transceiver and the PCM, the PATS transceiver or the PCM. 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. Replace the transceiver module. |
| B2431 | The ignition key was not programmed. Make sure that the correct key is being used. |
