Note | Alternator on vehicles with start/stop system: |
| Until now the alternator and the voltage regulator were connected together via their own wires to the engine and onboard supply control unit. For vehicles with start/stop system, the information transmission occurs via a LIN data bus to the diagnostic interface for data bus. Via the CAN data bus, it supplies information to other control units such as the engine control unit. |
