Pinpoint Test I: DTC B10D7:05

Normal Operation

During each vehicle start sequence, when the key is turned to the START or ON position, the Passive Anti-Theft System (PATS) transceiver reads the PATS key identification code and sends the data to the Instrument Panel Cluster (IPC). If there is a bad transponder in the key that is in the ignition lock cylinder, or if there was a concern during the programming of the PATS key, DTC B10D7:05 may set, and the vehicle experiences a PATS no-start.

- DTC B10D7:05 ( PATS Key: System Programming Failures) - a continuous DTC that sets when there was a failure during the key programming procedure.

This pinpoint test is intended to diagnose the following:

- PATS key programming concern
- PATS key concern (transponder)


PINPOINT TEST I: DTC B10D7:05

-------------------------------------------------
I1 CHECK BOTH PATS KEYS


NOTE: Check to make sure the new PATS keys are approved Ford encoded PATS keys. Unapproved PATS keys do not always operate correctly over various temperature ranges. (PATS keys from Ford, Rotunda, Strattec or Huf are approved Ford PATS keys.)

NOTE: Follow this procedure using both PATS keys.

- Obtain both PATS keys from the customer and follow the procedure using one PATS key, then the other. If the customer only has one PATS key, it is necessary to cut a new PATS key.
- If it is necessary to cut a new PATS key, cut the new key to match the original key. Program the PATS keys. Refer to Key Programming Using Diagnostic Equipment Using Diagnostic Equipment.
- Insert the first PATS key.
- Ignition ON.
- Clear the IPC DTCs.
- Ignition OFF.
- Ignition ON.
- Retrieve and record the IPC DTCs.
- Ignition OFF.
- Insert the second PATS key.
- Ignition ON.
- Clear the IPC DTCs.
- Ignition OFF.
- Ignition ON.
- Retrieve and record the IPC DTCs.
- Is DTC B10D7:05 present with either key?

Yes
REPLACE the damaged key with the new key that was cut (if present), or CUT a new key to replace the damaged key. DISCARD the damaged key. PROGRAM the keys. REFER to Key Programming Using Diagnostic Equipment Using Diagnostic Equipment. CLEAR the DTCs. CYCLE the ignition. REPEAT the self-test. TEST the system for normal operation.

No
If other IPC DTCs are retrieved, REFER to Multifunction Electronic Modules Testing and Inspection.

If no IPC DTCs are retrieved, the system is OK.
