Anti-Theft

Pinpoint Test D: DTC B10D7:8F

Normal Operation

- DTC B10D7:8F (PATS (Passive Anti-Theft System) 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 (Passive Anti-Theft System) key

- PATS (Passive Anti-Theft System) 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 Integrated Keyhead Transmitter (IKT) Key Programming Using Diagnostic Equipment .

- Insert the first PATS (Passive Anti-Theft System) key.

- Ignition ON.

- Clear the IPC (Instrument Panel Cluster) DTCs.

- Ignition OFF.

- Ignition ON.

- Retrieve and record the IPC (Instrument Panel Cluster) DTCs.

- Ignition OFF.

- Insert the second PATS (Passive Anti-Theft System) key.

- Ignition ON.

- Clear the IPC (Instrument Panel Cluster) DTCs.

- Ignition OFF.

- Ignition ON.

- Retrieve and record the IPC (Instrument Panel Cluster) DTCs.

Is DTC B10D7:8F retrieved for one or both PATS (Passive Anti-Theft System) 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 . CLEAR the DTCs. CYCLE the ignition.
REPEAT the self-test.

If DTC B10D7:8F is retrieved for both PATS (Passive Anti-Theft System) keys, GO to D2.

No
The system is OK. CHECK all the 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.

D2 INSTALL A NEW PATS (Passive Anti-Theft System) TRANSCEIVER

NOTE: Replacement of the PATS (Passive Anti-Theft System) transceiver does not require the PATS (Passive Anti-Theft System) keys to be programmed into the IPC (Instrument Panel Cluster) again.

- Ignition OFF.

- Install a new PATS (Passive Anti-Theft System) transceiver. Refer to Passive Anti-Theft System (PATS) Transceiver .

- Ignition ON.

- Clear the IPC (Instrument Panel Cluster) DTCs.

- Ignition OFF.

- Ignition ON.

- Retrieve the IPC (Instrument Panel Cluster) DTCs.

Are any PATS (Passive Anti-Theft System) DTCs retrieved?

Yes
GO to D3.

No
The system is OK. CHECK all the 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.

D3 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. 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.
