Pinpoint Test B: DTC B10D7:87
Normal Operation
- DTC B10D7:87 (PATS Key: Missing Message) - a continuous and on-demand DTC that sets when no
Passive Anti-Theft System (PATS) key has been read by the Instrument Panel Cluster (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 can 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 IPC DTCs.
- Ignition OFF.
- Ignition ON.
- Retrieve the IPC DTCs.
- Is DTC B10D7:87 retrieved?
Yes
GO to B2.
No
If any other IPC DTCs are retrieved, REFER to Body Control Systems.
If no DTCs are retrieved, the system is OK at this time.
-------------------------------------------------
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 Using Diagnostic Equipment.
- Ignition ON.
- Clear the IPC DTCs.
- Ignition OFF.
- Ignition ON.
- Retrieve the IPC DTCs.
- Using all existing keys, then the newly programmed key (if applicable), is DTC B1600 present?
Yes
If DTC B10D7:87 was present for both keys or the new key (if present), GO to B3.
If DTC B10D7:87 was not present for the new key, the original key may be damaged and should be replaced. REPLACE the damaged key with a new key. REFER to Key Programming Using Diagnostic Equipment Using Diagnostic Equipment. CLEAR the DTCs. CYCLE the ignition. REPEAT the self-test. TEST the system for normal operation.
No
If any other IPC DTCs are retrieved, REFER to Body Control Systems.
If no 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 Service and Repair.
- Ignition ON.
- Clear the IPC DTCs.
- Ignition OFF.
- Turn the key to the ON position using an existing customer PATS key.
- Retrieve the IPC DTCs.
- Is DTC B10D7:87 retrieved?
Yes
GO to B4.
No
The system is OK at this time.
-------------------------------------------------
B4 CHECK FOR CORRECT IPC OPERATION
- 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 Instrument Panel, Gauges and Warning Indicators. RESET the parameters. REFER to Passive Anti-Theft System (PATS) Parameter Reset Passive Anti-Theft System (PATS). PROGRAM the PATS keys into the new IPC. REFER to Key Programming Using Diagnostic Equipment Using Diagnostic Equipment. CYCLE the ignition. REPEAT the self-test.
No
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CLEAR the DTCs. CYCLE the ignition. REPEAT the self-test.
