Task
After engine start speed is reached, interrupt the circuit (circuit 50) M1to the solenoid switch of the starter.




  Design
The solenoid switch of the starter is operated not through the ignition/start switch S2/1, but in drive position P or N 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 operated in the start position, the engine control unit activates an automatic start control. Once the 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 engine start operation.
 
Once the engine start operation is initiated, shutting off circuit 50 at the ignition/start switch has no effect. The starter rotates until the specified start speed is reached, or for about 5 seconds at an engine temperature of +80 °C, for a maximum of 10 seconds if the engine is cold.
