Ignition Switch (Via Can)
The engine control module (ECM) calculates the status of the signal from the central electronic module (CEM) via CAN communication.
Position 2 = Ignition switch position in position 2 (ignition on).
Position 3 = Ignition switch position in position 3 (start).
Engine running = Ignition switch position in position 2 (ignition on) and the engine running.
