Description - CAN CONNECTION LINES - Fiat PANDA 1.1

This vehicle is equipped with a CAN (Controller Area Network) system of electrical connections: it involves a software and hardware solution which is designed to manage the resources on the vehicle efficiently allowing:the sharing of information between the various electronic units;the intergration of several electronic units through one network;a high network information exchange speed;advantages in economic terms because there is a considerable reduction in the wiring/connectors inside the vehicle;superior standards in terms of quality and reliability.The advantage of using a CAN system stems from the fact that communication takes place between numerous control units and consequently the number of signals to be managed is very high.The system on the standard versions uses a low speed CAN serial line (B CAN) for communication between Nodes.767NODES are all the electrical/electronic devices and control units that contain a specific interface (NETWORK INTERFACE) that allow data, information and signals travelling via the CANs to be transmitted and received.The B-CAN (low speed) network comprises 2 electrical wires, one White/Pink shown in the wiring diagram as the B CAN-A cable and one Black/Pink one shown in the wiring diagram as the B CAN-B cable.The transmission of information on this pair of wires takes place by means of 2 voltage levels, one High and one Low, associated with the B CAN-A cable and the B CAN-B cable respectively.For more details on the operating principle of the B CAN, consult the DESCRIPTION and OPERATION section..

Operational description - CAN CONNECTION LINES - Fiat PANDA 1.1

The electronic control units that communicate via the 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.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 O, the body computer node receives/sends signals coming:from the electric steering control unit M086, pin 5, 10 connector B;from the engine management control unit M010, pin 6 and 32 connector B.From connector I the body computer node receives/sends the signals coming from the instrument panel E050, pin 8,9 connector A.From connector H the body computer node receives/sends the signals to the diagnostic socket R010, pin 6, 14.
