169002266 - E1050 CAN CONNECTION LINES - FUNCTIONAL DESCRIPTION (Smart gearbox)
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 CANFrom 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 6, 14.
Operational description
The nodes which communicate with one another via the C CAN are:
- body computer node M001, from pin 11, 12 connector D;
- from the electric steering control unit M086, pin 2, 3, 7, 8 of connector B;
- brake system control unit M051 , from pins 45, 25, 35, 14.
Operational description
The nodes which communicate with one another via the C CAN are:
- the engine management control unit M010, from pin 52, 36 connector B;
- "selespeed" transmission control unit M054 , from pins 19, 7, 45, 33 connector A;
