Pinpoint Test C: DTC B10D7:51

Anti-Theft - Without Intelligent Access (IA)

Pinpoint Test C: DTC B10D7:51

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).

- DTC B10D7:51 (PATS (Passive Anti-Theft System) Key Not Programmed)- a continuous and on-demand DTC that sets when there is an unprogrammed PATS (Passive Anti-Theft System) key. There is no issue with the PATS (Passive Anti-Theft System) key itself, but the key must be programmed into the PATS (Passive Anti-Theft System) memory (unless the maximum number of keys are already programmed).

This pinpoint test is intended to diagnose the following:

- PATS (Passive Anti-Theft System) key

- IPC (Instrument Panel Cluster)

PINPOINT TEST C : DTC B10D7:51

NOTE: Large metallic objects, electronic devices on the key ring that can be used to purchase gasoline or similar items, or a second key on the same key ring as the PATS (Passive Anti-Theft System) key may cause vehicle starting concerns and record DTCs under certain conditions. If a fault cannot be identified, examine the customer key ring for such objects or devices. If present, inform the customer that they need to keep these objects from touching the PATS (Passive Anti-Theft System) key while starting the engine. These objects and devices cannot damage the PATS (Passive Anti-Theft System) key, but can cause a momentary concern if they are too close to the key during engine start. If a concern occurs, turn the ignition switch off and restart the engine with all other objects on the key ring held away from the ignition key. Check to make sure the PATS (Passive Anti-Theft System) key used by the customer is an approved Ford PATS (Passive Anti-Theft System) key. (PATS (Passive Anti-Theft System) keys from Ford, Rotunda, Strattec or Huf are approved Ford PATS (Passive Anti-Theft System) keys.)

NOTE: Only 8 PATS (Passive Anti-Theft System) keys can be programmed into the IPC (Instrument Panel Cluster) during normal programming procedures (with the unlimited key mode being the exception). If the N_KEYCODE (number of keys programmed) PID reads more than 2 and less than 8, the concern may be the PATS (Passive Anti-Theft System) key being used is an unprogrammed key. Verify this by also viewing the MASTERKEY (verifies if the key is programmed) PID. It must read Present for the key to be valid.

C1 RETRIEVE THE DTCs

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

If only one key is available, cut a new key and program the keys. Refer to Key Programming Using Diagnostic Equipment- Without Intelligent Access (IA) .

- If both keys are available, program the keys. Refer to Key Programming Using Diagnostic Equipment- Without Intelligent Access (IA) .

- 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.

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

- 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 B10D7:51 retrieved for both PATS (Passive Anti-Theft System) keys?

Yes
GO to C2.

No
If DTC B10D7:51 is retrieved for one PATS (Passive Anti-Theft System) key, REPLACE that key and PROGRAM the new key. REFER to Spare Key Programming - Using Diagnostic Equipment . CLEAR the DTCs. CYCLE the ignition. REPEAT the self-test.

If DTC B10D7:51 is not retrieved for either key, the system is OK. CHECK all customer PATS (Passive Anti-Theft System) keys by attempting to start the vehicle with each key to verify all other PATS (Passive Anti-Theft System) keys are programmed.

C2 CHECK FOR CORRECT IPC (Instrument Panel Cluster) OPERATION

NOTE: When a new IPC (Instrument Panel Cluster) is installed, the PATS (Passive Anti-Theft System) keys must be programmed into the new IPC (Instrument Panel Cluster).

NOTE: When a new IPC (Instrument Panel Cluster) is installed, the parameters must be reset in the IPC (Instrument Panel Cluster) and the PCM.

- Disconnect the IPC (Instrument Panel Cluster) connector.

- Check for:
- corrosion

- damaged pins

- pushed-out pins


- Connect the IPC (Instrument Panel Cluster) connector and make sure it seats correctly.

- Operate the system and verify the concern is still present.

Is the concern still present?

Yes
INSTALL a new IPC (Instrument Panel Cluster). TEST the system for normal operation.

No
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
