Theory of Operation
The Anti-Theft feature is fully integrated with the software of the Engine Control Module (ECM) and communicates directly with the RoadRelay unit. This provides for the most secure engine immobilizer available as it cannot be bypassed, hot wired, electronically scanned or interrogated. When activated with the engine shutdown, the Anti-Theft feature completely disables the ECM controlled fuel system, thereby preventing unauthorized startup. When activated with the engine idling, the Anti-Theft feature will electronically lock the throttle, ensuring that the vehicle remains fully protected even when the engine has not been shutdown.
