Pinpoint Test D: DTC B10D7:8F

WARNING: This page is about a different car, the 2010 Mercury Milan, 2010 Lincoln MKZ, and 2010 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
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 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  key used by the customer is an approved Ford PATS  key. (PATS keys from Ford, Rotunda, Strattec or Huf are approved Ford PATS  keys.)
NOTE: This vehicle uses a Huf Integrated Keyhead Transmitter (IKT) key. If replacing an IKT  key for any of these vehicles, it is recommended that the original Huf IKT  key be replaced with another Huf IKT  key. There are minor visual differences both externally and internally between the Huf IKT  key and IKT  keys used on other Ford, Lincoln, and Mercury vehicles that may be noticed by the customer. These visual differences do not affect the IKT  key functionality in any way. Rotunda should supply a Huf IKT  key when ordering replacement/new keys for this vehicle. The Owner's Literature can provide additional information concerning these differences. If replacing an IKT  key (or adding another key) with a standard PATS  key (not an IKT  key), any of the brands mentioned above (Ford, Rotunda, Strattec or Huf) can operate the system.
  1. D1 RETRIEVE THE DTCs 
    • 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  keys, GO to  D2.

    • No:  The system is OK. CHECK all the customer PATS  keys by attempting to start the vehicle with each key to verify all other PATS  keys are programmed.
  2. D2 INSTALL A NEW PATS TRANSCEIVER 
    NOTE: Replacement of the PATS  transceiver does not require the PATS  keys to be programmed into the IPC  again.
    • Ignition OFF.
    • Install a new PATS  transceiver. Refer to Removal and Installation .
    • Ignition ON.
    • Clear the IPC  DTCs.
    • Ignition OFF.
    • Ignition ON.
    • Retrieve the IPC  DTCs.
    • Are any PATS DTCs retrieved? 
    • Yes:  GO to  D3.
    • No:  The system is OK. CHECK all the customer PATS  keys by attempting to start the vehicle with each key to verify all other PATS  keys are programmed.
  3. D3 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?
