DescriptionThis vehicle features a CAN network(Controller Area Network) system of electrical connections: it involvesa software and hardware solution which is designed to manage theresources on the vehicle in an increasingly efficient way, allowing:data to be shared between the various electronic units;the integration of several electronic units in one network;a high data exchange speed in the network;cost-effective solutions, since the number of wiring harnessesand connectors are considerably reduced in the vehicle;a higher standard in terms of quality and reliability.The advantage of using a CAN system stemsfrom the fact that the communication involves numerous control unitsand consequently the number of signals managed is very high.For this reason the signals 'travel' onCAN type (double) serial Bus, where one wire is associated withthe high level (H) and the other the low level (L); These CAN Bussignals are differential, i.e. the value assigned to each bit isrepresented by the different voltge of CAN-H and CAN-L.The various electronic units which makeup the system, known as network 'Nodes', are connected to the CANby means of communication interfaces known as transreceivers; Theseconnection interfaces, integrated in the actual electronic units,form the gates for sending/reading information at the CAN or atthe serial lines.A 'transmission protocol', i.e. the setof rules allowing the communication between two or more ECUs (calledNodes) by means of data or data package exchanges, is required for CANserial line data circulation.The main element in the network is the BodyComputer.The Body Computer node 'wakes the systemup' when the ignition key is turned to the ON position (if thereis a Body Computer failure, the task of waking the system up isentrusted to the instrument panel).The Body Computer also carries outthe functions of controlling the network, which makes it possibleto supply information on:the network activity status;the functional failure status of the individual electronicunits (nodes);the possible CAN failure.The various electronic units process thevarious signals coming from their sensors both for their own managementand for the other control units, to which they are sent via the CANThe specific structure adopted onthis vehicle consists of two CANs which connect nodes belongingto two different areas:C-CAN for 'dynamic control' of the vehicle (high speed):bus CAN-H and CAN-L;B-CAN for the management of 'bodywork functions' (lowspeed): bus CAN-A and CAN-B;te two CAN communication networks are connected to oneanother by means of a gateway for transferring joint information,located in the Body Computer Node. The diagnosis of the nodes connected tothe bodywork network is achieved via the CAN, whilst the vehicledynamic control network is diagnosed using the special K lines 2428143SeeE8010DIAGNOSTIC MULTIPLE CONNECTOR . The system also uses additionional 'traditional'serial lines for the various connections; for example, in the connectionbetween the Body Computer and the alarm / volumetric sensors . The distribution of power takes place viathe junction units and/or fuse boxes, connected to the control elements(relays and static actuators) in order to ensure the maximum level ofelectrical protection and the minimum degree of wiring complexity 2427886SeeE1010SUPPLY .
Functional description The Body Computer M1 is supplied directly by the battery fromthe line protected by the maxifuse F1 of the engine compartmentjunctio unit B1 at pin 18 of connector F of the interface with theunderdashboard control unit B2. The Body Computer M1 receives a supplycontrolled by the ignition (INT) at pin 9 of connector F of theinterface with the underdashboard control unit B2 : this signalis designed to 'wake up the network'. The pins 9 and 8 of connector M1 areearthed. The nodes connected to the Body ComputerM1 via the C-CAN high-speed link are:electric steering control unit M86engine management control unit M10 ;ABS control unit M50 ;robotized gearbox control unit M54;yaw sensor K074The following nodes are connectedto the Body Computer M1 via the B-CAN low speed network:underfacia control unit B2 ;instrument panel E50driver door control unit M66 , passenger door M67 ;radio controls on the steering wheel D47 ;radio P20;climate control system control unit M70.
