Description - INSTRUMENT PANEL - Fiat STILO 2.4 20v Fino a 04/2005

The gauges and warning lights which form the instrument panel are grouped in a single instrument containing:electronic speedometerelectronic rev countercoolant temperature gauge, with overheating warning lightfuel gauge, with reserve warning lightengine oil pressure gauge ( 2.0 24V only)engine oil temperature gauge ( 2.0 24V only)engine oil level gauge ( 1.9 JTD and 1.9 JTD 16V only)warning lights.The instrument panel is a node on the CAN network 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.

The ignition-operated power supply (INT) of the instrument panel E50 reaches pin 1 of connector A through the line of fuse F37 of the unit under the dashboard B2 ; the direct supply reaches pin 2 of connector A through the line of fuse F53 of the unit under the dashboard B2 ; pin 7 of connector A is earthed (earth controlled by the Body Computer M1 ).The instrument panel E50 is connected from pins 3 and 4 of connector A to the Body Computer M1 and via the latter to the whole CAN network: via CAN the signal for the electronic speedometer arrives (coming from the ABS control unit M50 ): this signal is replicated from pin 37 of M50 to pin 7 of connector A of the Body Computer M1 .The electronic rev counter receives the rpm signal coming via CAN from the engine management control unit M10 .The fuel gauge is controlled in accordance with the signals coming from the fuel gauge sender unit located in the fuel pump assembly N40 - at pins 4 and 15 of the Body Computer M1 , and from here via CAN to the instrument panel E50 .The brake pad wear warning light is controlled by a signal sent to pin 23 of connector B of body computer M1 from the approriate sensor K20 .The low brake fluid/handbrake applied warning light comes on through a signal from the handbrake switch I40 , which reaches pin 24 of connector E of the Body Computer M1 , or from the signal from the low brake fluid level sensor K25 , which reaches pin 18 of connector A of M1 .All these signals are transferred via CAN to the instrument panel E50 .
