The starter-alternator has the following further tasks:

Reading in of sensors and signals 

The input factors are read in via the following connections:

Direct line 

The circuit 30c signal (crash signal) is read in via a direct line.

Hybrid CAN 

Among others, the starter-alternator reads in the following signals via the hybrid CAN:

Evaluation of input factors 

The integrated microprocessor evaluates the input factors read in.

Sending signals 

Among others, the starter-alternator transmits the following signals via the hybrid CAN:

The functions that use these signals are described in the individual function descriptions (see block diagram or function schematic).
