DESCRIPTION - INSTRUMENT PANEL - Fiat BRAVO 1.4 16v TJet

The control panel is installed behind the steering wheel. It is connected to the CAN network and includes 4 gauges built using step motors.the control panel display is available in two versions depending on the vehicle''s on-board features:- Multifunction display - LOW specifications- Reconfigurable multifunction display - HIGH specificationsIn both configurations a single instrument contains:- electronic speedometer- Fuel level gauge (with insufficient fuel level warning light)- engine coolant temperature gauge (with overheating warning light)- electronic rev counter- display (available in two different versions)- warning lightsA buzzer inside the instrument can produce signals of different intensities to perform the following functions:- alarm/warning/danger signals- direction indicators / hazard warning lights activation- Pushbutton roger beep- Sealt Belt Reminder signal- doors open signal- handbrake signal- tyre pressure signalThe instrument panel is a CAN node through which information is exchanged with the Body Computer and with the other electronic units.- Speedometer: the function of the speedometer includes displaying the vehicle speed in the instrument panel: this information comes from the ABS and engine control units, via the Body Computer.- Engine rpm: this function involves the display on the instrument panel of the engine rotation speed by means of the message sent via the CAN from the engine management control unit.- Milometer: the mileometer function includes the display and memorising of the total and trip mileage: Mileage information is processed by the Body Computer by means of a counter that is sent via the CAN network to the instrument panel. The trip counter that forms part of the Trip Computer can be reset using a TRIP button on the right steering wheel stalk.- Fuel level: the Body Computer receives the signal from the sensor integrated in the pump assembly inside the fuel tank and processes it to guarantee suitable filtering/damping for the panel gauge, also managing the reserve warning light. The circuit is capable of detecting a fault in the wiring or in the sensor and providing the instrument panel with a suitable reading: if there is a system malfunction, the pointer is at the start of the scale and the reserve warning light flashes.- Engine coolant temperature this function involves the display of the engine coolant temperature in the instrument panel and the overheating warning light coming on by means of messages sent via the CAN from the engine management control unit. The temperature reading is always guaranteed, even in extreme operating conditions.- Minimum engine oil pressure: this function involves the display on the instrument panel of the engine oil pressure warning light by means of the message sent via the CAN from the engine management control unit.- Brake pad wear state: this function involves the specific warning light coming on: the Body Computer detects the brake pad wear status when braking (signal from the brake pedal) in a prolonged manner (occasional signals are ignored).- Handbrake applied: the Body Computer acquires the handbrake status from a special switch and notifies the instrument panel of activation via the CAN network. The function turns on the low brake fluid level warning light on the instrument panel. A buzzer is also activated if this signal is associated with the exeeding of a set speed threshold.- Insufficient brake fluid: this function involves the "insufficient brake fluid level" warning light in the instrument panel coming on with the signal sent by the Body Computer via the CAN.For more detailsThe general fault signal summarises the faults detected by a set of systems and components:- Inertia switch operation- Engine oil pressure sensor failure- Rain / dusk sensor failure- Parking sensor failure- Tyre inflation pressure monitoring failureExterior lights failure: The Body Computer contains a check function that specifically monitors exterior light operation and turns on a warning light if a fault is detected: side light, number plate, rear fog, turn signal and brake light faults (including brake light fuse failure).The instrument panel setup menu can be used to activate or adjust a series of functions using the MODE + and - buttons located in the control panel in the middle of the dashboard, left side; these functions are:- seat belt buzzer adjustment- dusk sensor setting adjustment- date and time adjustment- TRIP setting (trip B, unit of measurement, language)- horn and button volume adjustment- brightness adjustment- central locking autoclose function- Service zeroing- passenger Air Bag exclusion767The operation of the warning lights and adjustment which do not come under any other functions is illustrated below: the other warning lights and displays are described and illustrated in the diagrams for the components to which they refer.

FUNCTIONAL DESCRIPTION - INSTRUMENT PANEL - 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 insufficient brake fluid level/handbrake warning light is lit up by a signal from the handbrake switch I40 that reaches pin 20 of connector D of the Body Computer M1 or from the signal from the brake fluid level sensor K25 that reaches pin 24 of connector A of M1. The brake pad wear warning light is controlled on the basis of the signal that reaches pin 32 of connector B of the Body Computer M1 from the sensor K20.All these signals are transferred via the CAN to the instrument panel E50.The MODE + and - controls are located in the control unit in the centre of the dashboard, left 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 E50 to pins 13 and 16 of the instrument panel E50.767There is only one direct instrument panel connection to turn on a warning light: this is the EOBD warning light: pin 18 of E50 receives a direct earth signal generated by the diagnostic systemof engine control unit M10.orThe internal logic for E50, which also manages the headlamp adjustment function, sends a control signal to the motors in the lamps from pin 7 of E50, whilst the enablement signal reaches pin 8 (dipped headlamps on).The Trip Computer zeroing button, located in the steering column switch unit H5, sends an earth signal to pin 9 of connector A of E50.
