Functional Description (F55 & F56): 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.
NOTE:
With intelligent generator control, the alternator voltage is correspondingly more frequently in the low voltage range in order to achieve a better battery charge.
