Pinpoint Test A: DTC B10D7:05

Normal Operation

When the Body Control Module (BCM) enters a key programming state, it activates the transceiver to read the key in the ignition. If a valid Passive Anti-Theft System (PATS) key is used and there are no concerns with the PATS (Passive Anti-Theft System) the key is programed into the BCM (Body Control Module) memory.

- DTC B10D7:05 (PATS (Passive Anti-Theft System) Key: System Programming Failure)- sets when a Passive Anti-Theft System (PATS) key is unsuccessfully programmed into the BCM (Body Control Module).

This pinpoint test is intended to diagnose the following:

- PATS (Passive Anti-Theft System) key

PINPOINT TEST A : DTC B10D7:05

A1 CHECK THE BCM (Body Control Module) DTCs FROM THE SELF-TEST

- Check the recorded results from the BCM (Body Control Module) self-test.

Is DTC B10D5: 13, B10D7: 87, B10D7: 8F, or B10D9:87 retrieved?

Yes
REFER to the BCM (Body Control Module) DTC Chart. RESOLVE these DTCs first.

No
GO to A2.

A2 CHECK THE PATS (Passive Anti-Theft System) KEY

- NOTE: The keys must have "HA" or "SA" stamped on the key blade.
Check that the correct PATS (Passive Anti-Theft System) keys are used with the vehicle. Compare the Integrated Keyhead Transmitters (IKTs) with the one shown in Anti-Theft Anti-Theft - Perimeter in the Description and Operation.

Are the correct keys being used?

Yes
ATTEMPT to program the key again. If key programming fails, DISCARD the damaged key and PROGRAM a new key. REFER to Key Programming - Program a Key Using Two Programmed Keys or Key Programming Using Diagnostic Equipment Programming and Relearning. CLEAR the DTCs. REPEAT the self-test.

No
OBTAIN the correct key(s) for the vehicle. PROGRAM the new key(s). REFER to Key Programming - Program a Key Using Two Programmed Keys or Key Programming Using Diagnostic Equipment Programming and Relearning. CLEAR the DTCs. REPEAT the self-test.
