DESCRIPTION - TRIP COMPUTER - Fiat BRAVO 1.4 16v TJet
The Trip Computer shows vehicle trip, consumption and mileage details on the control panel display.There are two types of fully independent Trip Computer modes (A and B); the displays can be activated by pressing the TRIP button on the right steering wheel stalk switch.The data display mode follows a preset order:TRIP A:- Range- Distance travelled - Average fuel consumption - Instantaneous fuel consumption - Average speed - Trip timeTRIP B:- Distance travelled - Average fuel consumption - Average speed - Trip timeBoth functions can be zeroed (rest - start of a new journey).The Trip B is a function that can be excluded using the setup menu in the instrument panel.For more detailsTrip Computer data is calculated inside the instrument panel.The instrument panel is a CAN node through which information is exchanged with the Body Computer and with the other electronic units.This diagram shows the operation of instrument panel functions that also affect the Trip Counter.
FUNCTIONAL DESCRIPTION - TRIP COMPUTER - Fiat BRAVO 1.4 16v TJet
The ignition-controlled supply (INT) for the instrument panel E50 reaches pin 3 of the Body Computer M1 via the line for fuse F37 of the junction unit under the dashboard B2.The direct power supply reaches pin 2 from the Body Computer M1 via the line for fuse F53 of the junction unit under the dashboard B2Pin 1 is earthed.The Body Computer M1 receives a direct supply from the battery via the line protected by maxifuse B99 at pin 18 of connector F of the interface with the junction unit under the dashboard B2; the ignition-controlled supply (INT) reaches pin 9 of connector F of the interface with the junction unit B2.The instrument panel E50 is connected from pins 5 and 6 with the Body Computer M1 and via the latter to the entire CAN: the signal reaches the electronic speedometer (from the ABS control unit M50) via the CAN:The ABS control unit M50 also sends a discreet speedometer signal (VSO) to pin 10 of connector A of M1The electronic rev counter, on the other hand, receives the engine rpm signal received from the engine management control unit M10 via the CAN.The fuel level gauge is controlled by means of signals coming from the level gauge located in the fuel pump assembly N40 - at pins 7 (signal) and 21 (earth) of connector D of the Body Computer M1 and from there via the CAN to the instrument panel E50.The TRIP electronic module uses these signals to process information on instantaneous and average fuel consumption, range, average speed, Km travelled, duration etc.The Trip Computer zeroing button, located in the steering column switch unit H5, sends an earth signal to pin 9 of E50.The MODE + and - controls are located in the control panel in the middle of the dashboard, left hand side H90B.The reference earth reaches pin 1 of H90B from pin 36 of connector G of M1; analogue signals are sent to the instrument panel to pins 13 and 16 of E50.
