223002502 - E4010 INSTRUMENT PANEL - DESCRIPTION (DPF, MY 2005)

The indicators and the warning lights that make up the on board instrumentation are grouped together in a single instrument which contains:- fuel level gauge with reserve warning light;- engine coolant temperature gauge with overheating warning light;- rev counter;- speedometer;- warning lights;- reconfigurable multifunction display.The instrument panel is a CAN node through which information is exchanged with the body computer and with the other electronic units.A series of data is shown on the instrument panel digital display, which includes:- milometer/trip meter;- clock;- headlamp alignment corrector reading;- trip computer.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 fuel level is displayed by means of an electronic circuit inside the actual module that operates the gauge and the reserve warning light as well (when the guage is at 15% of the tank capacity).The internal logic also "dampens" the signal preventing fluctuations.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.Vehicle speed: the speedometer signal is supplied by the speedometer sensor.This signal is processed by the body computer and sent to the instrument panel to display the vehicle speed.For more details on the multifunction display,    See E4080 TRIP COMPUTERRev counter: this function involves the display on the instrument panel of the engine rotation speed by means of the signal from the special sensor sent via the CAN from the engine management control unit.The light beam for the front light clusters can be adjusted using the headlamp alignment corrector buttons to the left of the dashboard.    See E3080 HEADLAMP AGLINMENT CORRECTOREngine oil pressure sensor: 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.Other information is acquired directly by the body computer which sends it to the instrument panel which manages the switching on of the appropriate warning lights:- handbrake applied: the warning light for the handbrake status is controlled by the specific switch;- insufficient brake fluid pressure: the body computer receives the insufficient brake fluid pressure signal and sends it to the instrument panel.Lastly, there are other warning lights located inside the instrument panel but they are managed directly by the respective electronic units:- Air Bag failure warning light;- passenger Air Bag disabled warning light;- seat belt not fastened warning light.    See E7030 AIRBAGOther information, described in the various wiring diagrams, is acquired via the CAN from the instrument panel which lights up the relevant warning lights:- side lights activation;    See E2010 SIDE LIGHTS / NO. PLATE LIGHTS- direction indicators / hazard warning lights activation;    See E2020 DIRECTION INDICATORS / HAZARD WARNING LIGHTS- rear fog lamps activation;    See E2031 REAR FOG LAMPS- activation of exterior side lights/no. plate lights, direction indicators/hazard warning lights, brake lights, rear fog lamp failure;    See E2021 BRAKE LIGHTS- main beam headlamps activation;    See E2012 MAIN BEAM HEADLAMPS- fog lights activation;    See E2030 FOG LIGHTS- activation of rear windscreen and exterior rear view mirrors defrosting;    See E3030 HEATED REAR WINDSCREEN AND DOOR MIRROR DEFROSTING- doors open warning light;    See E3040 CENTRAL LOCKING- insufficient battery recharging;    See E5010 STARTING AND RECHARING- i.e. system/EOBD failure;- activation of heater plugs;- presence of water in diesel filter;- insufficient engine oil pressure;- activation of general failure warning light for: failure of engine oil pressure sensor, exceeding of speed limit, presence of water in the diesel filter and diesel filter sensor failure.    See E5050 DIESEL ENGINES ELECTRONIC MANAGEMENT- particle filter blocked;    See E5070 FAP PARTICLE FILTER SYSTEM- activation of vehicle protection system;    See E7010 CODE- activation of ABS failure;- EBD braking system failure (insufficient brake fluid pressure warning light);    See E7020 ABSWhen the ignition is turned ON and during normal operation if there are any failure signals, the instrument panel carries out a fault diagnosis of the "handbrake applied/insufficient brake fluid" and "ABS/EBD failure" warning lights.At the end of this warning lights check, the display will signal any failure (in one or more of the warning lights).Through the multifunction display the instrument panel will provide the driver with the outside temperature reading and notify them, if it is less than 3 degrees centigrade, of the possibility of finding ice on the road surface.For further details,    See descriptions 5560 INSTRUMENTS
