Anti-Theft
Pinpoint Test C: DTC B10D7:51
Normal Operation
- DTC B10D7:51 (PATS (Passive Anti-Theft System) Key: Not Programmed)- a continuous and on-demand DTC that sets when there is an unprogrammed Passive Anti-Theft System (PATS) key. There may not be a concern with the PATS (Passive Anti-Theft System) key itself, but the key must be programmed into the PATS (Passive Anti-Theft System) memory (unless the maximum number of keys are already programmed).
This pinpoint test is intended to diagnose the following:
- PATS (Passive Anti-Theft System) key
- Instrument Panel Cluster (IPC)
PINPOINT TEST C : DTC B10D7:51
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 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 (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 switch 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.)
NOTE: Only 8 PATS (Passive Anti-Theft System) keys can be programmed into the IPC (Instrument Panel Cluster) during normal programming procedures (with the unlimited key mode being the exception). If the N_KEYCODE (number of keys programmed) PID reads more than 2 and less than 8, the concern may be the PATS (Passive Anti-Theft System) key being used is an unprogrammed key. Verify this by also viewing the MASTERKEY (verifies if the key is programmed) PID. It must read Present for the key to be valid.
NOTE: This vehicle uses a Huf Integrated Keyhead Transmitter (IKT) key. If replacing an IKT (Integrated Keyhead Transmitter) key for any of these vehicles, it is recommended that the original Huf IKT (Integrated Keyhead Transmitter) key be replaced with another Huf IKT (Integrated Keyhead Transmitter) key. There are minor visual differences both externally and internally between the Huf IKT (Integrated Keyhead Transmitter) key and IKT (Integrated Keyhead Transmitter) keys used on other Ford and Lincoln vehicles that may be noticed by the customer. These visual differences do not affect the IKT (Integrated Keyhead Transmitter) key functionality in any way. Rotunda should supply a Huf IKT (Integrated Keyhead Transmitter) key when ordering replacement/new keys for this vehicle. The Owner's Literature can provide additional information concerning these differences. If replacing an IKT (Integrated Keyhead Transmitter) key (or adding another key) with a standard PATS (Passive Anti-Theft System) key (not an IKT (Integrated Keyhead Transmitter) key), any of the brands (Ford, Rotunda, Strattec or Huf) can operate the system.
C1 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 Integrated Keyhead Transmitter (IKT) Key Programming Using Diagnostic Equipment .
- If both keys are available, program the keys. Refer to Integrated Keyhead Transmitter (IKT) Key Programming Using Diagnostic Equipment .
- Ignition ON.
- Clear the IPC (Instrument Panel Cluster) DTCs.
- Ignition OFF.
- Ignition ON.
- Retrieve the IPC (Instrument Panel Cluster) DTCs.
Is DTC B10D7:51 retrieved for both PATS (Passive Anti-Theft System) keys?
Yes
GO to C2.
No
If DTC B10D7:51 is retrieved for one PATS (Passive Anti-Theft System) key, REPLACE that key and PROGRAM all the keys. REFER to Integrated Keyhead Transmitter (IKT) Key Programming Using Diagnostic Equipment . CLEAR the DTCs. CYCLE the ignition. REPEAT the self-test.
If DTC B10D7:51 is not retrieved for either key, the system is OK. CHECK all 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.
C2 CHECK FOR CORRECT IPC (Instrument Panel Cluster) OPERATION
- 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). RESET the parameters in both the IPC (Instrument Panel Cluster) and the PCM. REFER to Passive Anti-Theft System (PATS) Parameter Reset . PROGRAM the PATS (Passive Anti-Theft System) keys into the new IPC (Instrument Panel Cluster). REFER to Integrated Keyhead Transmitter (IKT) Key Programming 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.
