The direct supply for the instrument panel E050 reaches pin 2 of connector A via the line protected by fuse F53 of the junction unit under the dashboard B002. The supply controlled by the ignition (INT), on the other hand, reaches pin 1 of connector A via the line protected by fuse F37 of the junction unit under the dashboard B002.The manual command for zeroing the trip mileage displayed on the trip computer is transmitted from the left control panel H091 (pin 3) and is received by the instrument panel at pin 5 of connector A. The signal from the potentiometer to increase or decrease the intensity of the trip computer light arrives at pin 11 of connector B. See E2530 INSTRUMENT LIGHTINGThe instrument panel E050 is connected from pins 3 and 4 of connector A with the Body Computer M001 and, through the latter, to the entire CAN, from which it acquires information for the function from the other electronic units present on the vehicle.The instrument panel E050 communicates, via the B-CAN, with the info-telematic control unit M065 (pins A1 and A3 of connector B) for the repetition of the navigation parameters. The info-telematic control unit M065 is supplied directly by the battery at pin A7 of connector B via the line protected by fuse F39 of the junction unit under the dashboard B002.The braking control unit M051 is involved in calculating the vehicle speed and sending the speedometer signal both via the C-CAN (pins 1 and 2) and via a signal (from pin 16 to pin 7, connector A of the Body Computer M001). The braking control unit M051 is supplied directly by the battery (pin 12) via the line protected by fuse F02 of the engine compartment junction unit B001.The fuel level gauge N040 signal also reaches pins 4 and 15 of connector F of the Body Compuer M001. This signal is then repeated to the trip computer for calculating the average and instant fuel consumption and the vehicle range.The body computer M001 is also connected, via the C-CAN (pins 32 and 33 of connector B), with the engine management control unit M010 (pins 45 and 61 of connector A for the 3.0 petrol and 2.4 petrol versions and pins 83 and 84 for the 2.4 JTD 20 V version) which calculates the engine rpm on the basis of the signal arriving from the engine rpm sensor K046 at pins 10 and 59 of connector B for the petrol versions and 27 and 12 for the diesel versions. The result is then transmitted to the system via the C-CAN and displayed on the instrument panel < R1 > and used by the trip computer for its internal strategies. See E4010 INSTRUMENT PANELThe signals coming from the normally open switches for signalling that one of the 4 doors is open reach pins 8 and 16 (connector F) and 25 and 26 (connector G) of the Body Computer M001. See E3040 CENTRAL LOCKINGThis signal is transmitted via the CAN to the trip computer in order to zero the trip mileage display when the doors are opened.On this version, with automatic transmission, the trip computer is equipped with a gear engaged display. The information displayed arrives, via the CAN, from the automatic transmission control unit M055.The automatic transmission control unit M055 is supplied at pin 7 of connector A directly by the battery via the line protected by fuse F64 of the luggage compartment junction unit B045; it interfaces with the CAN, by means of pins 12 and 13, sending the gear engaged input to be displayed to the trip computer.
