DescriptionThe trip computer on the instrument panel displays the following information:General Trip:Distance travelled [Km] or [mi]Instant fuel consumption [l/100km] or [mpg]Average consumption [l/100km] or [mpg]Range [Km] or [mi]Average speed [km/h] or [mph]Journey time [hh:mm]Trip B (partial):Journey distance B Km or miAverage consumption B l/100 km or mpgAverage speed B km/h or mphJourney time B hh:mmThe values (B) are calculated from the last resest (pressing the SET button on the stalk unit right lever) or automatically after a stop of 2 h with the ignition off.23When the calculated range value is equal to that of the fuel reserve, the display shows a 'Limited Range' message and a buzzer sounds.The control panel to the left of the steering wheel in the dashboard contains the buttons for the set up and for switching from one TRIP set of measurements to another:the 'Mode' button confirms the settings (pressed briefly); memorizing the settings and returning to the standard screen (pressed for longer).the '+' and '-' buttons select, set and adjust the functions in the menuThere is also the possibility of showing that the speed limit has been exceeded on the instrument panel. This option can be activated/deactivated using the special setup in the instrument panel.If activated, the instrument panel receives the vehicle speed figure from the network and compares it with the level set; if the current speed exceeds the level set, the instrument panel warns the driver by means of the buzzer. For more details 2398709Characteristic of working principle5560INSTRUMENT PANELThe Trip Computer data are calculated within the instrument panel. The instrument panel is a node on the CAN network through which it exchanges information with the Body Computer and the other electronic units. 2399312SeeE4010INSTRUMENT PANELThis diagram shows the operation of those functions relating to the instrument panel which also affect the Trip Computer.
Functional description The ignition-operated power supply (INT) of the instrument panel E50 reaches pin 3 of connector A through the line of fuse F37 of the unit under the dashboard B2; the direct supply reaches pin 2 of connector A through the line of fuse F53 of the unit under the dashboard B2; pin 1 of connector A is earthed (earth controlled by the Body Computer M1 pin 36 of connector G). The instrument panel E50 is connected from pins 5 and 6 of connector A to the Body Computer M1 and via the latter to the whole CAN network: via CAN the signal for the electronic speedometer arrives (coming from the ABS control unit M50): this signal is replicated from pin 16 of M50 to pin 7 of connector A of the Body Computer M1. The electronic rev counter receives the rpm signal coming via CAN from the engine management control unit M10 . The fuel gauge is controlled in accordance with the signals coming from the fuel gauge sender unit located in the fuel pump assembly N40 - at pins 4 (positive) and 15 (negative) of connector D of the Body Computer M1, and from here via CAN to the instrument panel E50.The TRIP electronic module uses these signals to process instantaneous and average fuel consumption information, range, average speed, mileage, duration etc. The Trip Computer 'SET' button, located on the stalk unit H5, sends an earth signal to pin 9 of connector A of E50. The'MODE' '+' and '-' controls for unit H91 send analogue signals to the instrument panel E50 to pins 13 and 16 of connector B.
