Pinpoint Test D: DTC B10D7:8F

Anti-Theft - Integrated Keyhead Transmitter (IKT)

Pinpoint Test D: DTC B10D7:8F

Normal Operation
- DTC B10D7:8F ( PATS Key: Erratic) - a continuous and on-demand DTC that sets when only a partial Passive Anti-Theft System (PATS) key was read. Remote starter equipment can also cause this DTC.

This pinpoint test is intended to diagnose the following:

- PATS key
- PATS transceiver
- Instrument Panel Cluster (IPC)



PINPOINT TEST D: DTC B10D7:8F

-------------------------------------------------
D1 RETRIEVE THE DTCs


- If only one key is available, cut a new key and program the keys. Refer to Key Programming Using Diagnostic Equipment - Integrated Keyhead Transmitter (IKT) Integrated Keyhead Transmitter (IKT).
- 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.
- Is DTC B10D7:8F retrieved for one or both PATS keys?

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 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.

-------------------------------------------------
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 Passive Anti-Theft System (PATS) Transceiver [1][2]Anti-Theft - Passive Anti-Theft System (PATS) - Backup Transceiver.
- 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.

-------------------------------------------------
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?

Yes
INSTALL a new IPC. REFER to Instrument Panel, Gauges and Warning Indicators. RESET the parameters in both the IPC and the PCM. REFER to Passive Anti-Theft System (PATS) Parameter Reset - Integrated Keyhead Transmitter (IKT) With Integrated Keyhead Transmitter (IKT). PROGRAM the PATS keys into the new IPC. REFER to Key Programming Using Diagnostic Equipment - Integrated Keyhead Transmitter (IKT) Integrated Keyhead Transmitter (IKT). 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.
