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

Possible Causes
- passive anti-theft system (PATS) transceiver
- PCM
- PATS key
- circuit 1203 (BK/LB) open
- circuit 1215 (WH/LG) open or short to power
- circuit 1216 (GY/OG) open or short to power
- circuit 1266 (RD/YE) open or short to ground
