Charging System - Functional Description: Alternator: Notes

The alternator exchanges data with the engine control unit using a serial data interface. The alternator provides the engine control unit with information, e.g. type and manufacturer. This enables alternator-specific information to be processed inside the engine control unit and adapts the control of the alternator to the installed alternator type.

Notice! Observe intelligent generator control! 

With intelligent generator control, the alternator voltage is correspondingly more frequently in the low voltage range in order to achieve a better battery charge.
