INSTRUMENT PANEL - DESCRIPTION
Description
The gauges and warning lights which form the instrument panel are grouped in a single instrument containing:
- electronic speedometer
- electronic rev counter
- coolant temperature gauge, with overheating warning light
- fuel gauge, with reserve warning light
- warning lights.
The instrument panel is a node on the CAN through which it exchanges information with the Body Computer and the other electronic units.
- Speedometer: the function displays the vehicle speed on the instrument panel: this information comes from the ABS control unit, via the Body Computer.
- Engine rpm: the function displays the engine rpm on the instrument panel, via the message sent on the CAN network from the engine management control unit.
- Odometer: this function displays and memorises the total mileage counter and trip recorder: the distance travelled information is processed by the Body Computer via a counter; the specific button located on the panel beside the steering wheel resets the trip recorder.
- Fuel gauge: the Body Computer receives the signal from the sensor integrated in the pump unit in the fuel tank and processes it so as to ensure appropriate filtering / damping to the instrument panel gauge, and also controls the lighting up of the ''reserve'' warning light.
- Engine water temperature: the function displays the water temperature on the instrument panel and lights up the water overheating warning light by means of the messages sent via the CAN network from the engine management control unit.
- Minimum engine oil pressure: the function lights up the minimum oil pressure warning light on the instrument panel via the message sent on the CAN network from the engine management control unit.
- Brake pad wear: the function lights up the specific warning light: the Body Computer detects the state of the brake pad wear associated with the presence of braking (signal from the brake pedal) which is prolonged (intermittent indications are ignored).
- Inertial switch state: the instrument panel receives a signal from the switch, lights up the relevant warning light and communicates the activation to the other nodes via the CAN network.
- Driver''s seat belt not fastened: the instrument panel receives a signal from the seat belt unfastened switch and lights up the relevant warning light.
- Handbrake on: the warning light relating to the handbrake state is controlled by the specific switch; in addition, if this signal is associated with a particular speed threshold being surpassed, an acoustic signal is activated: the signal is sent via the CAN from the Body Computer.
- Low brake fluid: the function lights up the ''low brake fluid level'' warning light on the instrument panel: the signal is sent via the CAN from the Body Computer.
Other warning lights are located on the instrument panel, but managed directly by other electronic units:
- Air Bag failure warning light;
- passenger Air Bag disablement warning light;
- i.e. failure warning light (EOBD)
The active matrix LCD also shows some commands or messages relating to the use of the radio, telephone

The gauges and warning lights which form the instrument panel are grouped in a single instrument containing:
- electronic speedometer
- electronic rev counter
- coolant temperature gauge, with overheating warning light
- fuel gauge, with reserve warning light
- warning lights.
- LCD for milometer, headlamp alignment correction, etc.
- LCD with information relating to the clock, date, trip computer, fault display, etc.

- Minimum engine oil pressure: the function lights up the minimum oil pressure warning light on the instrument panel via the message sent on the CAN network from the engine management control unit.
- Engine oil temperature: this function involves the display of the engine oil temperature, acquired directly from the instrument by means of a special sensor as well as the display of an overheating warning;
- Brake pad wear: the function lights up the specific warning light: the Body Computer detects the state of the brake pad wear associated with the presence of braking (signal from the brake pedal) which is prolonged (intermittent indications are ignored).
- Inertial switch state: the instrument panel receives a signal from the switch, lights up the relevant warning light and communicates the activation to the other nodes via the CAN network.

- Minimum engine oil pressure: the function lights up the minimum oil pressure warning light on the instrument panel via the message sent on the CAN network from the engine management control unit.
- Engine oil level: this function signals the engine oil level during starting (for about 10 seconds) on the display. It is the instrument panel which actually operates a hot wire oil level sensor. If the level of the oil is too low in relation to the minimum level, the ''minimum oil level'' message is sent.
- Water in diesel filter: the instrument panel receives information concerning the presence of water in the diesel filter via the CAN from the engine management control unit. in these circumstances, the warning light comes on.
- Brake pad wear: the function lights up the specific warning light: the Body Computer detects the state of the brake pad wear associated with the presence of braking (signal from the brake pedal) which is prolonged (intermittent indications are ignored).
- Inertial switch state: the instrument panel receives a signal from the switch, lights up the relevant warning light and communicates the activation to the other nodes via the CAN network.
