Normal Operation
During each vehicle start sequence, the powertrain control module (PCM) queries the passive anti-theft system (PATS) key and compares the information with the PATS key information stored in the PCM memory. The PCM then enables the starting functions of the engine. The PATS transceiver provides the interface between the PATS key and the PCM.

Possible Causes
- PATS transceiver
- PATS key
- PCM
