Starter control takes over actuation of the starter (M1) and interrupts the circuit (circuit 50) to the starter solenoid switch (starter deactivation) after reaching the engine start speed. By actuating the ignition starter switch at the electronic ignition switch control unit (N73), from position "2" (ignition ON) to position "3" (START), starter detection is performed by the ME-SFI control unit (N3/10). The solenoid switch of the starter is actuated via the starter relay by the ME-SFI control unit. The voltage supply to the starter relay (coil) is supplied through circuit 87. The starter relay is actuated by the ME-SFI control unit with a ground signal.

If the starting procedure has started, the actuation of the ignition starter switch from position "3" back into position "2" no longer has any influence (touch start). When reaching the engine start speed of 400 up to 700 rpm or a starting time of approx. 5 to 40 seconds (dependent on the engine temperature), the ME-SFI control unit interrupts the negative activation to the starter relay and therefore ends the starting procedure.
