Normal Operation

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 a bad 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 is a failure during the key programming procedure.

This pinpoint test is intended to diagnose the following: 

• PATS key programming concern
• PATS key concern (transponder)
