Task Interrupting the circuit (circuit 50) to the starter solenoid switch after engine start speed is reached (switching off starter).

Design The starter solenoid switch is actuated not through the ignition/starter switch, but through the starter relay by the engine control unit. The voltage for the starter relay (coil) is supplied through circuit 87. The starter relay is actuated by the engine control unit through GND.

Function When the ignition/start switch is turned from position 2 into the start position, start recognition is activated by the engine control unit through circuit 50. As soon as an engine start speed of 400 to 700 rpm is reached, the engine control unit interrupts the ground actuation to the starter relay and thus the start operation.

with manual transmission The starter control is only enabled when the clutch pedal is operated. When the clutch pedal is depressed, the clutch pedal switch is operated for start enable (S40/5).
