Pinpoint Test B: DTC B10D7:87

Anti-Theft

Pinpoint Test B: DTC B10D7:87

Normal Operation

- DTC B10D7:87 (PATS (Passive Anti-Theft System) Key: Missing Message)- a continuous and on-demand DTC that sets if the Instrument Panel Cluster (IPC) does not receive a key read. When this occurs, the vehicle experiences a Passive Anti-Theft System (PATS) no-start.

This pinpoint test is intended to diagnose the following:

- PATS (Passive Anti-Theft System) key

- PATS (Passive Anti-Theft System) transceiver

- IPC (Instrument Panel Cluster)

PINPOINT TEST B : DTC B10D7:87

B1 RETRIEVE THE DTCs

- Ignition ON.

- Clear the IPC (Instrument Panel Cluster) DTCs.

- Ignition OFF.

- Ignition ON.

- Retrieve the IPC (Instrument Panel Cluster) DTCs.

Is DTC B10D7:87 retrieved?

Yes
GO to B2.

No
If any other IPC (Instrument Panel Cluster) DTCs are retrieved, REFER to Body Control Systems.

If no DTCs are retrieved, the system is OK. The concern may have been caused by an intermittent concern with the key, the transceiver or the IPC (Instrument Panel Cluster).

B2 CHECK BOTH PATS (Passive Anti-Theft System) KEYS

- Obtain both PATS (Passive Anti-Theft System) keys from the customer and follow the procedure using one PATS (Passive Anti-Theft System) key, then the other. If the customer only has one PATS (Passive Anti-Theft System) key, it is necessary to cut a new PATS (Passive Anti-Theft System) key.

- If it is necessary to cut a new PATS (Passive Anti-Theft System) key, program the new PATS (Passive Anti-Theft System) key. 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.

Using all existing keys, then the newly programmed key (if applicable), is DTC B10D7:87 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 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 Integrated Keyhead Transmitter (IKT) Key Programming Using Diagnostic Equipment . CLEAR the DTCs. CYCLE the ignition. REPEAT the self-test. TEST the system for normal operation.

No
If any other IPC (Instrument Panel Cluster) DTCs are retrieved, REFER to Body Control Systems.

If no IPC (Instrument Panel Cluster) DTCs are retrieved, the system is OK. The concern may have been caused by an intermittent concern with the key, the transceiver or the IPC (Instrument Panel Cluster).

B3 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.

NOTE: Do not use the PATS (Passive Anti-Theft System) key that may have been programmed in Step B2.

- 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.

- Turn the key to the ON position using an existing customer PATS (Passive Anti-Theft System) key.

- Retrieve the IPC (Instrument Panel Cluster) DTCs.

Is DTC B10D7:87 retrieved?

Yes
GO to B4.

No
The system is OK.

B4 CHECK FOR CORRECT IPC (Instrument Panel Cluster) OPERATION

- Ignition OFF.

- 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.
