This vehicle is equipped with a CAN (Controller Area Network) system of electrical connections.

The different electronic units that make up the system, known as network Nodes, are connected to the CAN; the main element of the network is the Body Computer.

The various electronic units process the various signals coming from the corresponding sensors both for their own management and for other control units to which they are sent via the CAN.

The structure consists of two CAN communication networks which connect nodes belonging to two different areas:

- C-CAN for dynamic vehicle control (high speed): bus CAN-H and CAN-L;

- B-CAN for the management of standard body functions (low speed): bus CAN-A and CAN-B;

the two CAN communication networks are connected to one another by a gateway for transferring joint information, located in the Body Computer Node

  See E1050 CAN CONNECTION LINES 

A dedicated A-BUS ISO 5 serial line manages the connection with the rain and dusk sensor, located near the interior rear view mirror.

A special A-BUS ISO 5 serial line manages the connection with

- automatic wiping (rain sensor);

- automatic lighting (dusk sensor);

- alarm (siren and volumetric/anti-tilt sensors);

- Start&Stop system (battery charge sensor).

Another LIN serial line manages the connection with the "seat belt fastened display", also located near the interior rear view mirror

The Body Computer M001 - connector A - receives a direct power supply from the battery through the line protected by maxi fuse F01 of the engine compartment junction unit B001.

The Body Computer M001 receives an ignition-operated power supply (INT) at pin 11 of connector E.

Pin 9 of connector E of M001 provides the Body Computer with a reference earth.

The rain and dusk sensor, located near the interior rear view mirror P065 - pin 3 - is connected via the A-BUS serial line to pin 48 of connector F of M001 and sends automatic operation signals to the windscreen wiper and the side lights and dipped headlamps.

The same A-BUS serial line is also connected to the alarm volumetric/tilt sensors K62 - pin 4.

The A-BUS serial line is connected from pin 56 of connector B of the Body Computer M1 with the alarm siren P90 - pin 2 - and with the battery charge sensor K059, pin 1 of connector A.

The LIN serial line leaves pin 4 of the instrument panel E050 connecting with the seat belts not fastened display located in the interior rear view mirror P065 - pin 4.
