E1050 CAN CONNECTION LINES - FUNCTIONAL DESCRIPTION (Euro 5)

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 following nodes are connected to the Body Computer M001 via the C-CAN high speed network:

  • the diagnostic socket R010

  • the steering angle control unit M092 (only versions with ESP);

  • the ABS/ESP braking system control unit M051;

  • the engine management control unit M010.

In detail, the Body computer M001 is connected:

  • from pins 28 and 29 of connector H with the diagnosis socket R010 (pins 6 and 14);

  • for the versions with ESP, from pins 38 and 37 of connector D, with the steering angle control unit M092 (pins 4 and 2 of connector B);

  • for the versions without ESP, from pins 38 and 37 of connector D, with the ABS/ESP braking system control unit M051 (pins 26 and 14).

For the versions with ESP, the steering angle control unit M092 is connected to pins 26 and 14 of the braking system control unit M051 through pins 3 and 1.

The ABS/ESP braking system control unit M051 is then connected, via pins 15 and 27, to the engine management control unit M010 (pins 83 and 84 of connector B for the 3.0 JTD version, pins 70 and 69 of connector B for the 2.3 JTD version, pin 25 and 24 of connector B for the 2.0 JTD version).

The following nodes are connected to the M001 Body Computer via the low speed B-CAN:

  • from pins 10 and 25 of connector H, the radio P020 (pins A3 and A1 of connector A) and the Bluetooth control unit M162 (pins 14 and 30);

  • from pins 11 and 26 of connector H, the instrument panel E050 (pins 5 and 6);

  • from pins 12 and 27 of connector H, the Air Bag control unit M060 (pins 7 and 8 connector A);

  • from pins 9 and 24 of connector H, the diagnosis socket R010 (pins 9 and 1);

  • from pins 41 and 40 of connector D, the climate control system control unit M070 (pins 1 and 2);

  • from pins 45 and 60 of connector F, the parking sensor control unit M084 (pins 12 and 6 of connector A), the controlled suspension control unit M046 (pins M and L of connector B) and the transformer socket P125 (pins 9 and 10 of connector A) – where provided -.

On versions with optional radio preparation, there is no B-CAN for the radio.
