Pinpoint Test D: DTC B10D7:8F

Anti-Theft - Without Intelligent Access (IA)

Pinpoint Test D: DTC B10D7:8F

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 B10D7:8F (PATS (Passive Anti-Theft System) Key Erratic)- a continuous and on-demand DTC that sets when only a partial PATS (Passive Anti-Theft System) key was read. Remote starter equipment can also cause this DTC.

This pinpoint test is intended to diagnose the following:

- PATS (Passive Anti-Theft System) key

- PATS (Passive Anti-Theft System) transceiver

- IPC (Instrument Panel Cluster)

PINPOINT TEST D : DTC B10D7:8F

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 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 keys from Ford, Rotunda, Strattec or Huf are approved Ford PATS (Passive Anti-Theft System) keys.)

D1 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) .

- 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 B10D7:8F retrieved for one or both PATS (Passive Anti-Theft System) keys?

Yes
If DTC B10D7:8F is retrieved for one 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 B10D7:8F is retrieved for both PATS (Passive Anti-Theft System) keys, GO to D2.

No
The system is OK. CHECK all the 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.

D2 INSTALL A NEW PATS (Passive Anti-Theft System) TRANSCEIVER

NOTE: Replacement of the PATS (Passive Anti-Theft System) transceiver does not require the PATS (Passive Anti-Theft System) keys to be programmed into the IPC (Instrument Panel Cluster) again.

- Ignition OFF.

- Install a new PATS (Passive Anti-Theft System) transceiver. Refer to Passive Anti-Theft System (PATS) Transceiver .

- Ignition ON.

- Clear the IPC (Instrument Panel Cluster) DTCs.

- Ignition OFF.

- Ignition ON.

- Retrieve the IPC (Instrument Panel Cluster) DTCs.

Are any PATS (Passive Anti-Theft System) DTCs retrieved?

Yes
GO to D3.

No
The system is OK. CHECK all the 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.

D3 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.
