Principles of Operation

Starting System - Anti-Theft Intervention 

The starting system is electronically controlled by the Passive Anti-Theft System (PATS). PATS is controlled by the instrument cluster. PATS recognizes the correct electronically coded ignition key and the instrument cluster will send a message to the PCM to provide a ground for the starter relay. The energized relay provides voltage to the starter solenoid allowing the starter motor to activate.
