Starting System: Description and Operation

GF15.30-P-3000BK Starter Control - Function







Starter control actuates the starter and interrupts the circuit (terminal 50) to the starter solenoid switch (starter disconnection) when the engine speed is achieved.

By operating the ignition start switch on the EIS control unit, from position "2" (ignition ON) to position "3" (START), the ME control unit detects the start

The solenoid switch of the starter is actuated by the ME control unit via the starter relay.

The voltage for the starter relay (coil) is supplied through circuit 15. The starter relay is actuated by the ME control unit by 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 control unit interrupts the negative activation to the starter relay and therefore ends the starting procedure.
