Starting the engine is only possible if the selector lever is switched to position "P" or "N". The CDI control unit (N3/9) receives the message about selector lever position "P" or "N" over the Controller Area Network-Bus Class C (engine compartment) (CAN-C) from the electronic selector lever module control unit (N15/5).
The CDI control unit also receives the message "terminal 50 ON" from the EIS [EZS] control unit (N73) (except model 461).
For model 461 the CDI control unit receives the signal "terminal 50 ON" via the ignition/starter switch (S2/1).

Model 203, 209
The CDI control unit actuates the starter (M1) over the integral starter relay (N10/1kS) in the front SAM control unit with fuse and relay module (N10/1).

Model 211, 219
The CDI control unit actuates the starter (M1) over the integral starter relay (N10/1kL) in the driver-side SAM control unit with fuse and relay module (N10/1).

Model 463
The CDI control unit actuates the starter (M1) via the relay starter integrated into the front SAM signal acquisition and actuation module (N10/1). N10/1kS

Model 461
The CDI control unit actuates the starter (M1) via the starter relay (K6).

The CDI control unit detects engine running via the crankshaft Hall sensor (B70) and via the "Circuit 61 ON" message and the end of the starting procedure via the "Circuit 50 OFF" message. The CDI control unit reacts by interrupting actuation of the starter.

If there is a repeat start after the end of starting procedure, a cutoff period of about 1.5 to 3 s is applied. This occurs so that the rotating pinion of the starter is prevented from meshing with the toothing on the engine clutch plate (ring gear protection).
