During each vehicle start sequence, when the key is turned to the START or ON position, the Passive Anti-Theft System (PATS) transceiver reads the PATS key identification code and sends the data to the Instrument Panel Cluster (IPC). If there is an inoperative transponder in the Integrated Keyhead Transmitter (IKT) key that is in the ignition lock cylinder, or if there was a concern during the programming of the IKT key, DTC B10D7:05 can set, and the vehicle experiences a PATS no-start.
- DTC B10D7:05 (PATS Key: System Programming Failures) - a continuous DTC that sets when there was a failure during the key programming procedure.
This pinpoint test is intended to diagnose the following:
- PATS key programming concern
- PATS key concern (transponder)
