B10D7:05

Anti-Theft

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 (Passive Anti-Theft System) key identification code and sends the data to the Instrument Panel Cluster (IPC). If there is a bad transponder in the Integrated Keyhead Transmitter (IKT) key that is in the ignition lock cylinder, or if there was a concern during the programming of the IKT (Integrated Keyhead Transmitter) key, DTC B10D7:05 can set, and the vehicle experiences a PATS (Passive Anti-Theft System) no-start.

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

This pinpoint test is intended to diagnose the following:

- PATS (Passive Anti-Theft System) key programming concern

- PATS (Passive Anti-Theft System) key concern (transponder)

PINPOINT TEST I : DTC B10D7:05

I1 CHECK BOTH PATS (Passive Anti-Theft System) KEYS

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

NOTE: Follow this procedure using both PATS (Passive Anti-Theft System) keys (using one at a time).

- Obtain both PATS (Passive Anti-Theft System) keys from the customer and follow the procedure using one PATS (Passive Anti-Theft System) key, then the other. If the customer only has one PATS (Passive Anti-Theft System) key, it is necessary to cut a new PATS (Passive Anti-Theft System) key (does not have to be an IKT (Integrated Keyhead Transmitter) key).

- If it is necessary to cut a new PATS (Passive Anti-Theft System) key, cut the new key to match the original key. Program the PATS (Passive Anti-Theft System) keys. Refer to Integrated Keyhead Transmitter (IKT) Key Programming Using Diagnostic Equipment .

- Ignition ON.

- Clear the IPC (Instrument Panel Cluster) DTCs.

- Ignition OFF.

- Ignition ON.

- Retrieve the IPC (Instrument Panel Cluster) 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 Integrated Keyhead Transmitter (IKT) Key Programming Using Diagnostic Equipment . CLEAR the DTCs. CYCLE the ignition. REPEAT the self-test. TEST the system for normal operation.

No
If other IPC (Instrument Panel Cluster) DTCs are retrieved, REFER to the Diagnostic Trouble Code (DTC) Chart in Body Control Systems. Body Control Systems

If no IPC (Instrument Panel Cluster) DTCs are retrieved, the system is OK.
