The Body Computer M001 receives a direct battery supply at pin A of connector A.

This direct battery power supply is protected upstream by fuse F71 (CPL1) of the B099 maxifuse control unit on the battery (connector D). On the Minibus versions, the above power supply is protected by fuse F73 (CPL1) of the maxifuse box B099 (connector D).

The Body Computer M001 also receives an ignition-operated supply (INT) at pin 2 of connector G.

It is connected to the earth of the central dashboard C022 (connector A) via pins 1 and 11 of connector G.

The rain and dusk sensor K125 (pin 2) is connected via the A-BUS serial line to the Body Computer M001 (pin 14 of connector F) and sends automatic operation signals to the windscreen wiper and the side lights and dipped beam headlights.

The same A-BUS serial line is connected from pin 50 of connector D of the Body Computer M001 with the alarm sensor P090 (pin 2).
