169002271 - E1050 CAN CONNECTION LINES - FUNCTIONAL DESCRIPTION (4x4, POWERED THROTTLE)
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.
From connector C, the body computer node receives/sends signals coming:
- from the electric steering control unit M086, pin 5, 10 connector B;
The nodes which communicate with one another via the C CAN are:
- body computer node M001, from pin 11, 12 connector D;
- the engine management control unit M010, from pin 52, 36 connector B;
- ABS control unit M050 from pins 14, 15, 25, 26;
