Normal Operation
During each vehicle start sequence, the transceiver module reads the encoded ignition key identification code and sends the data to the powertrain control module (PCM). The PCM then compares this data with stored values to determine start enable.

Possible Causes
- PATS transceiver
- PCM
- electronic encoded ignition key
