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 key that is in the ignition lock cylinder, or if there was a concern during the programming of the PATS (Passive Anti-Theft System) key, DTC B10D7:05 may 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 was 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.

- 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.

- 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 Key Programming Using Diagnostic Equipment Passive Anti-Theft System (PATS) Key Programming Using Diagnostic Equipment.

- Insert the first PATS (Passive Anti-Theft System) key.

- Ignition ON.

- Clear the IPC (Instrument Panel Cluster) DTCs.

- Ignition OFF.

- Ignition ON.

- Retrieve and record the IPC (Instrument Panel Cluster) DTCs.

- Ignition OFF.

- Insert the second PATS (Passive Anti-Theft System) key.

- Ignition ON.

- Clear the IPC (Instrument Panel Cluster) DTCs.

- Ignition OFF.

- Ignition ON.

- Retrieve and record 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 Key Programming Using Diagnostic Equipment Passive Anti-Theft System (PATS) 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 Body Control Systems.

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