Abstract:
The present invention relates to a method for feedback of states of an electric component to an engine control device of an internal combustion engine using a control unit for the electric component including a detection device configured to detect faults. The method includes configuring the control unit, connecting the control unit to the engine control device via a signal line, receiving a PWM signal generated in the engine control device, tying the signal line to ground for a feedback of data of the electric component to the engine control device; and identifying a fault based on a duration of the connection to ground.
