Normal Operation and Fault Conditions
When the ignition transitions to RUN or START, the BCM activates the PATS transceiver to read the key in the ignition lock cylinder. If the BCM does not receive a PATS key code or if the code is invalid, the PATS prevents the engine from starting.
REFER to: Passive Anti-Theft System (PATS) - Overview .
