323000420 - 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 display is available in three versions depending on the vehicle''s on-board features:- MODAL type digital display;- COMFORT type multifunction display;- MATRIX type reconfigurable multifunction display;The last two versions allow the Blue&Me system functions to be displayed. See E3570 INTEGRATED RADIO PHONEThe panel includes 4 gauges which have stepping motors.In all configurations a single instrument contains:- Electronic speedometer;- Electronic rev counter;- Fuel level gauge (with insufficient fuel level warning light);- Engine coolant temperature gauge (with overheating warning light);- Display;- Warning lights.The available control panel versions (MODAL, COMFORT and MATRIX) therefore differ according to the technology of the display.The display includes the display of several useful information icons, such as:- service due (spanner symbol - excluding the MODAL version - ;- headlamp alignment position;- outdoor temperature and ice hazard (snowflake symbol) - excluding the MODAL version - ;- robotized gearbox gear selection indicator and AUTO and ECO operating mode (where present) - excluding MODAL version - ;- date and time.On the MODAL version, the service expiry is signalled by a dedicated warning light.A buzzer inside the instrument can produce signals of different intensities to perform the following functions:- alarm/warning/danger signalling;- parking sensor signalling;- the trip computer readings;- set vehicle speed exceeded;- doors open warning light;- robotized gearbox signals (where present);- handbrake applied with the vehicle moving signalling;- Seat Belt Reminder;- direction indicators / hazard warning lights activation;- push button 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: the function allows the display of the vehicle speed in the instrument panel; this information comes from the ABS/ESP control unit or, on versions without these devices, via the dedicated speedometer sensor (LOW trim level).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 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 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 with 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;- speed limit exceeded;- inertia switch operated;- diesel filter sensor failure (diesel versions);- rain sensor failure (versions with electrochromic mirrors);- robotized gearbox failure. | The operation of the warning lights 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. |
