Pinpoint Test B: DTC B10D7:87

Anti-Theft - Without Intelligent Access (IA)

Pinpoint Tests

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 key identification code and sends the data to the Instrument Panel Cluster (IPC).

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

This pinpoint test is intended to diagnose the following:

- PATS key
- PATS transceiver
- IPC

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 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 key while starting the engine. These objects and devices cannot damage the PATS 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 key used by the customer is an approved Ford PATS key. (PATS keys from Ford, Rotunda, Strattec or Huf are approved Ford PATS 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 IPC DTCs are retrieved, REFER to Multifunction Electronic Modules Testing and Inspection.

If no PATS IPC DTCs are retrieved, the system is OK.

-------------------------------------------------
B2 CHECK BOTH PATS KEYS

- Obtain both PATS keys from the customer and follow the procedure using one PATS key, then the other. If the customer only has one PATS key, it is necessary to cut a new PATS key.
- If it is necessary to cut a new PATS key, program the new PATS key. Refer to Key Programming Using Diagnostic Equipment - Without Intelligent Access (IA) Without Intelligent Access (IA).
- Insert the first PATS key.
- Ignition ON.
- Clear the IPC DTCs.
- Ignition OFF.
- Ignition ON.
- Retrieve and record the IPC DTCs.
- Ignition OFF.
- Insert the second PATS key.
- Ignition ON.
- Clear the IPC DTCs.
- Ignition OFF.
- Ignition ON.
- Retrieve and record the IPC 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) 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 IPC DTCs are retrieved, REFER to Multifunction Electronic Modules Testing and Inspection.

If no PATS IPC DTCs are retrieved, the system is OK.

-------------------------------------------------
B3 INSTALL A NEW PATS TRANSCEIVER

NOTE: Replacement of the PATS transceiver does not require the PATS keys to be programmed into the IPC again.

NOTE: Do not use the PATS key that may have been programmed in Step B2.

- Ignition OFF.
- Install a new PATS transceiver. Refer to Passive Anti-Theft System (PATS) Transceiver [1][2]Anti-Theft - Passive Anti-Theft System (PATS) - Backup Transceiver.
- Ignition ON.
- Clear the DTCs.
- Ignition OFF.
- Turn the key to the ON position using an existing customer PATS key.
- Retrieve the DTCs.
- Is DTC B10D7:87 retrieved?

Yes
GO to B4.

No
The system is OK.

-------------------------------------------------
B4 CHECK FOR CORRECT IPC OPERATION

NOTE: When a new IPC is installed, the PATS keys must be programmed into the new IPC.

NOTE: When a new IPC is installed, the parameters must be reset in the IPC and the PCM.

- Disconnect the IPC connector.
- Check for:
- corrosion
- damaged pins
- pushed-out pins
- Connect the IPC 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. REFER to Instrumentation, Message Center, and Warning Chimes Instrument Panel Cluster (IPC). 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.
