Fuel Enable Control

When the content theft deterrent system is armed, the Body Control Module (BCM) sends a fuel disable signal to the Powertrain Control Module (PCM). The PCM then disables the fuel injectors. This prevents engine start attempts.

When the system is disarmed, the BCM sends a fuel enable signal to the PCM. The PCM then enables fuel delivery to the engine, allowing the engine to start.
