DescriptionThe gauges and warning lights which form the instrument panel are grouped in a single instrument containing:electronic speedometer - milometer/trip meterdigital clockfuel gauge, with reserve warning lightwarning lightsThe speedometer signal comes from the sensor on the gearbox, this signal is 'repeated' for other functions which require the information.The milometer consists of an LCD which alternately shows the total and trip mileage or the outside temperature.The clock is digital and is adjusted through the two buttons in the centre/lower part of the actual instrument marked 'h' and 'min'.The fuel level is displayed by means of electronic circuitry inside the module which operates the gauge and the reserve warning light (when the gauge is at 1/8 of its travel). The internal logic 'damps' the signal avoiding fluctuations.The warning lights consist of LEDs built into the electronic circuit, and so cannot be replaced.The operation of the warning lights which are not included in other functions are illustrated in depth:insufficient brake fluid level/handbrake;minimum oil pressure;brake pad wear warning lightseat belt not fastened warning lightThe others are described and illustrated in the diagrams dealing with the components to which they refer:direction indicators (2888857SeeE2020DIRECTION INDICATORS / HAZARD WARNING LIGHTS)side lights (2888812SeeE2010SIDE LIGHTS / NO.

Functional description The supply controlled by the ignition (INT) for the instrument E50 reaches pin 2 of connector A from the line protected by fuse F1 of the junction unit B1 . Pins 3 and 4 of connector A are earthed. The instrument E50 is also supplied directly by the battery - pin 1 of connector A - via the line for the maxifuse J/B1 of B5 protected by fuse F10 of the junction unit B1 (supply for internal clock). Pins 4 and 5 of connector B receive signals coming from the fuel gauge, located in the electric pump unit N40 : these signals, processed by the internal electronic device, operate the fuel gauge and the reserve warning light. Insufficient engine oil pressure is signalled to pin 2 of connector C from the earth signal coming from the sensor K30 . The signal from the sensor K20 reaches pin 5 of connector C and lights up the brake pad wear warning light. Switch I45 signals the failed insertion of the seat belt in the special housing and lights up the appropriate warning light (function only present on some right hand drive markets). Signals from handbrake switch I40 and brake fluid level sensor K25 . reach pin 8 of connector B and pin 13 of connector C for E50 , respectively and light up the insufficient brake fluid level/handbrake warning light. The same warning light is on - together with the ABS failure warning light - if the ABS control unit detects problems involving the EBD function ( 2889551SeeE7020ABS ). The speedometer sensor K84 , located on the gearbox, sends signals to the instrument panel E50 to pins 8 and 9 of connector C: these signals, processed by the internal electronic device, operate the vehicle speed indicator and the milometer and the output is available: from pin 10 of connector C for the engine management control unit ( 2889373SeeE5030PETROL ENGINE ELECTRONIC MANAGEMENT or 2889410SeeE5050DIESEL ENGINES ELECTRONIC MANAGEMENT ), from pin 3 of connector B for the navigation system control unit ( 2889304SeeE4090NAVIGATOR ).
