Pinpoint Test I: DTC B10D7:05

Anti-Theft - Integrated Keyhead Transmitter (IKT)

Pinpoint Tests

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).

- DTC B10D7:05 (PATS Key: System Programming Failures) - a continuous DTC that sets when there was a failure during the key programming procedure. A bad transponder (in the PATS key) may also cause this DTC.

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 (using one at a time).

- 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 (does not have to be an IKT 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 - Integrated Keyhead Transmitter (IKT) Integrated Keyhead Transmitter (IKT).
- Insert the first PATS key.
- Ignition ON.
- Clear the IPC DTCs.
- Ignition OFF.
- Ignition ON.
- Retrieve and record the IPC DTCs.
- Ignition OFF.
- Remove the first PATS key.
- 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
CUT a new key to replace the damaged key (the key that DTC B10D7:05 is still present with). DISCARD the damaged key. PROGRAM the new key. REFER to Spare 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 DTCs other than PATS IPC DTCs are retrieved, REFER to Body Control Systems.

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