DescriptionThe trip computer on the instrument panel displays the followinginformation:General Trip:Range [km]Distance travelled [Km]Average consumption [km/l]Instantaneous consumption [km/l]Average speed [km/h]Journey time [hh:mm]Trip B (partial):Distance travelled B [Km]Average consumpterion B [Km/l]Average speed B [Km/h]Journey time B [hh:mm]The values (B) are calculated from the lastresest (pressing the SET button on the stalk unit right lever) orautomatically after a stop of 2 h with the ignition off. For more details 2427445Characteristic of working principle5560INSTRUMENT PANEL . The Trip Computer data are calculated withinthe instrument panel. The instrument panel is a node on the CANnetwork through which it exchanges information with the Body Computerand the other electronic units. 2428027SeeE4010INSTRUMENT PANELThis diagram shows the operation of thosefunctions relating to the instrument panel which also affect theTrip Computer.There is the possibility of showing thatthe speed limit has been exceeded on the instrument panel. Thisoption can be activated/deactivated using the special setup in theinstrument panel.If activated, the instrument panel receivesthe vehicle speed figure from the network and compares it with thelevel set; if the current speed exceeds the level set, the instrument panelwarns the driver by means of the buzzer.
Functional description The ignition-operated power supply (INT) of the instrument panel E50 reachespin 1 of connector A through the line of fuse F37 of the unit underthe dashboard B2 ; the direct supply reaches pin 2 of connectorA through the line of fuse F53 of the unit under the dashboard B2 ;pin 7 of connector A is earthed (earth controlled by the Body Computer M1 ). The instrument panel E50 is connectedfrom pins 3 and 4 of connector A to the Body Computer M1 and viathe latter to the whole CAN network: via CAN the signal for the electronicspeedometer arrives (coming from the ABS control unit M50): thissignal is replicated from pin 16 of M50 to pin 7 of connector Aof the Body Computer M1. The electronic rev counter receives therpm signal coming via CAN from the engine management control unit M10 . The fuel gauge is controlled in accordancewith the signals coming from the fuel gauge sender unit locatedin the fuel pump assembly N40 - at pins 4 and 15 of connectorD of the Body Computer M1, and from here via CAN to the instrumentpanel E50.The TRIP electronic module uses these signalsto process instantaneous and average fuel consumption information,range, average speed, mileage, duration etc. The Trip Computer zeroing 'SET' button,located on the steering column switch unit H5, sends an earthsignal to pin 16 of connector B of E50.
