When the anti-theft system is preparing to set, the circuit lights up the indicator light. When the system has been set, it continually turns the indicator light on for one second and turns it off for one second, thus blinking the indicator light. This anti-theft indicator is connected to the Engine Control Module (ECM) and outputs the key judgment of the immobilizer system.
