Description - CAN CONNECTION LINES - Fiat PANDA 1.3 JTD 16v
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 uses a low speed CAN serial network (B CAN) and a high speed network (C 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.The C-CAN (high speed) network comprises 2 electrical wires, one Green shown in the wiring diagram as the CAN-H cable and one Brown shown in the wiring diagram as the CAN-L 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 C CAN-H cable and the C CAN-L cable respectively.Shared information for the dynamic control of the vehicle is transferred via the C CAN whilst the B CAN manages the standard bodywork functions.The gateway for communication between the C CAN and B CAN is located in the body computer node.For more details on the operating principle of the B CAN and C CAN networks, consult the DESCRIPTION and OPERATION section..
Operational description - CAN CONNECTION LINES - Fiat PANDA 1.3 JTD 16v
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 signalsto the diagnostic socket R010, pin 6, 14.
Connection via C CAN
Operational description - CAN CONNECTION LINES - Fiat PANDA 1.3 JTD 16v
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.
