B10D7:87

Anti-Theft - Without Intelligent Access (IA)

Pinpoint Test B: DTC B10D7:87

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 B10D7:87 (PATS (Passive Anti-Theft System) Key: Missing Message)- a continuous and on-demand DTC that sets when no PATS (Passive Anti-Theft System) key has been read by the IPC (Instrument Panel Cluster).

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 B : DTC B10D7:87

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 key 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.)

B1 RETRIEVE THE DTCs

- Ignition ON.

- Clear the DTCs.

- Ignition OFF.

- Ignition ON.

- Retrieve the DTCs.

Is DTC B10D7:87 retrieved?

Yes
GO to B2.

No
If DTCs other than PATS (Passive Anti-Theft System) IPC (Instrument Panel Cluster) DTCs are retrieved, REFER to Body Control Systems.

If no PATS (Passive Anti-Theft System) IPC (Instrument Panel Cluster) DTCs are retrieved, the system is OK.

B2 CHECK 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, program the new PATS (Passive Anti-Theft System) key. 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.

- 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.

Using all existing keys, then the newly programmed key, is DTC B10D7:87 present?

Yes
If DTC B10D7:87 was present for both keys or the new key, GO to B3.

If DTC B10D7:87 was not present for the new key, the original key may be damaged and should be replaced. CUT a new key to replace the damaged key. REFER to Key Programming Using Diagnostic Equipment - Without Intelligent Access (IA) . CLEAR the DTCs. CYCLE the ignition. REPEAT the self-test. TEST the system for normal operation.

No
If DTCs other than PATS (Passive Anti-Theft System) IPC (Instrument Panel Cluster) DTCs are retrieved, REFER to Body Control Systems.

If no PATS (Passive Anti-Theft System) IPC (Instrument Panel Cluster) DTCs are retrieved, the system is OK.

B3 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.

NOTE: Do not use the PATS (Passive Anti-Theft System) key that may have been programmed in Step B2.

- Ignition OFF.

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

- Ignition ON.

- Clear the DTCs.

- Ignition OFF.

- Turn the key to the ON position using an existing customer PATS (Passive Anti-Theft System) key.

- Retrieve the DTCs.

Is DTC B10D7:87 retrieved?

Yes
GO to B4.

No
The system is OK.

B4 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.
