312001019 - E4010 INSTRUMENT PANEL - DESCRIPTION

DESCRIPTION

The control panel is fitted behind the steering wheel; its position guarantees maximum visibility/legibility of the information for the driver in all vehicle usage conditions (day/night) without reflections, distortions or double images.The control panel circular display is available in two versions depending on the vehicle''s on-board technological features:

  • COMFORT multifunctional display - LOW trim levels;
  • MATRIX reconfigurable multifunctional display - HIGH trim levels.
Both versions allow the display of the functions offered by the Bluetooth system.    See E3570 INTEGRATED RADIO PHONEThe MATRIX reconfigurable display also allows the display of a navigation map with the Blue&Me system.    See E4090 NAVIGATORThe panel includes 4 gauges, 2 of which employ step motors and 2 of which are digital gauges on the display.In both configurations a single instrument contains:

  • Electronic speedometer;
  • Electronic rev counter;
  • Digital fuel level gauge;
  • Digital engine coolant temperature gauge;
  • Display;
  • Warning lights.
The available control panel versions (COMFORT and MATRIX) therefore differ according to the technology of the display.The display includes the display of several useful information icons, such as:

  • engagement of CITY function;
  • service due (spanner symbol);
  • headlamp alignment position;
  • outdoor temperature and ice hazard (snowflake symbol);
  • date and time.
A buzzer inside the instrument can produce signals of different intensities to perform the following functions:

  • alarm/warning/danger signalling;
  • parking sensor signalling;
  • set vehicle speed exceeded;
  • doors open signalling;
  • handbrake applied with the vehicle moving signalling;
  • Seat Belt Reminder;
  • direction indicators / hazard warning lights acoustic signals;
  • Pushbutton Roger Beep.
The instrument panel is a CAN node through which information is exchanged with the Body Computer and with the other electronic units.Speedometer: its function allows the vehicle speed to be displayed on the instrument panel. This information is obtained from the braking system control unit via the Body Computer.Rev counter: this function involves the display on the instrument panel of the engine rotation speed by means of the data sent via the CAN from the engine management control unit.Mileometer: this function involves 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 to the instrument panel via the CAN. The trip counter that forms part of the Trip Computer can be reset using the special TRIP button on the right-hand steering wheel interface lever.    See E4080 TRIP COMPUTER Engine coolant temperature: this function involves the display of the engine coolant temperature level 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.Fuel level: the Body Computer receives the signal from the sensor built into the pump assembly inside the fuel tank and processes it to guarantee suitable filtering/damping for the instrument panel digital gauge; it also controls the lighting of the reserve warning light.The instrument panel also has various warning lights.Brake pad wear status: 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 applied status from the dedicated switch and communicates this information to the instrument panel via the CAN; also, if this signal is associated with a determined speed threshold being exceeded, an acoustic warning is activated.Insufficient brake fluid: this function involves the insufficient brake fluid level warning light in the instrument panel coming on; the signal sent by the Body Computer via the CAN.The general failure warning light summarises the faults detected by a series of systems and components, such as:

  • engine oil pressure sensor fault;
  • parking sensor fault;
  • intervention of the fuel cut off function - FPS (Fire Prevention System) signal - which cuts off the fuel;
  • fuel cut off function not available;
  • exterior lighting failure.
The signalling of exterior lights failure via the general failure warning light is managed by the Body Computer; it contains a check function that checks the operation of the exterior lights, lighting the warning light if a fault is detected with the lights or their connection:

  • side lights;
  • daylight lights (DRL);
  • number plate;
  • rear fog light;
  • direction indicator;
  • vehicle stop (excluding 3rd stop).
The operation of the warning lights which do not come under any other functions is illustrated below: the other warning lights are described and illustrated in the diagrams for the components to which they refer.
Together with the activation of the warning lights, there are several messages (subdivided by priority) which allow the specific identification of the fault.The use of the various settings in the instrument panel SET UP menu takes place via the MENU/ESC, + and - buttons to the right of the instrument panel. For example, settings relating to the following can be adjusted:

  • Vehicle internal lighting adjustment;
  • Speed limit;
  • Trip B enablement;
  • Time adjustment;
  • Date adjustment;
  • Repetition of audio information;
  • Auto close function (automatic central locking with vehicle moving);
  • Units of measurement (distances in Km or miles; fuel consumption in Km/l or l/100Km or mpg; temperature in °C or °F);
  • Language selection;
  • Volume of acoustic warnings / failure signals;
  • Button press volume;
  • Activation / deactivation of S.B.R. buzzer;
  • Planned maintenance indications;
  • Passenger Air Bag activation/deactivation;
  • Daylight lights (DRL) activation/deactivation.
In both trim levels the control panel is equipped with a brightness sensor that discriminates between night (night time) and day (daylight) conditions in order to suitably manage the lighting of the vehicle controls and displays.    See E2530 INSTRUMENT LIGHTING For further details,    See descriptions 5560 INSTRUMENTS The instrument panel receives a direct battery power supply and an ignition-operated power supply via two lines protected by two dedicated fuses in the Body Computer.
