169002280 - E1050 CAN CONNECTION LINES - FUNCTIONAL DESCRIPTION

Operational description

The electronic control units that communicate via the CAN (B CAN and C CAN) exchange information by means of the body computer node M001.The body computer node receives a direct battery supply at pin 1 connector A and an ignition-operated supply at pin 1 connector L.The body computer node M001 assumes the role of "information collector" for the information coming from the various nodes, thereby allowing the exchange of data between the B CAN and C CAN.Connection via B CAN

From connector O, the body computer node receives/sends signals coming:

  • from the radio receiver node M094, pin 1, 3 connector A;
  • from the climate control system control unit M070, pin 9, 10 connector B.

From connector I, the body computer node receives/sends signals coming:

  • from the instrument panel E050, pin 8, 9 connector A.

From connector H, the body computer node receives/sends signals:

  • to the diagnostic socket R010, pin 11, 20.

From connector C, the body computer node receives/sends signals:

  • to the electric steering control unit M086, pin 5, 10 connector B;
  • to the engine management control unit M010, pin 58, 59 connector B.
For vehicles equipped with the ELD system the braking system control unit M051 converses via the C-CAN with the body computer M001 from pins 25 and 45 and with the engine management control unit M010 from pins 14 and 35.
