184002182 - E4010 INSTRUMENT PANEL - DESCRIPTION

Description

The control panel is located in the middle of the dashboard. Its position ensures maximum visibility/legibility of the information in all conditions (day/night) for the driver without reflection, distortion or double images.The control panel comes in two versionsCOMFORT type control panel - LOW trim levelsMODAL type control panel - HIGH trim level

In both configurations a single instrument contains:

• 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 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 SET button for the right steering column switch unit lever zeros the trip meter.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.The circuit is capable of detecting any fault in the wiring or the sensor and providing a suitable reading for the instrument panel: if there is a system malfunction, the pointer is positioned at the start of the scale and the reserve warning light flashes. The ''fuel reserve'' reading is also signalled by a buzzer.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. The temperature reading is always guaranteed, even in limit operating conditions.From the key on, the coolant overheating is controlled by a continuous control signal through the dedicated red warning light.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.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.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.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.The switch is normally closed (N.C.) with the brake fluid at the maximum level (on right hand versions, on the other hand, it is normally open (N.A.).The ON/OFF type switchs is only monitored with the ignition on: if the brake fluid level is too low, the contact closes or opens sending an earth signal to the Body Computer.

General warning signal (check): the Body Computer contains a check function which controls a series of systems and components and lights up the appropriate warning light if a fault is detected; the following systems and/or components are controlled:

• Operation of inertia switch    See E3040 CENTRAL LOCKING,    See E5030 PETROL ENGINE ELECTRONIC MANAGEMENT,    See E5050 DIESEL ENGINES ELECTRONIC MANAGEMENT
• Exceeding of speed limit    See E4080 TRIP COMPUTER
• Engine oil pressure sensor failure    See E5030 PETROL ENGINE ELECTRONIC MANAGEMENT,    See E5050 DIESEL ENGINES ELECTRONIC MANAGEMENT
• Engine coolant temperature sensor failure    See E5030 PETROL ENGINE ELECTRONIC MANAGEMENT,    See E5050 DIESEL ENGINES ELECTRONIC MANAGEMENT
• Rain sensor failure    See E3020 WINDSCREEN WASH/WIPE
• Dusk sensor failure    See E2010 SIDE LIGHTS / NO. PLATE LIGHTS
• Window safety system failure    See E3050 ELECTRIC FRONT WINDOWS E3051 ELECTRIC REAR WINDOWS
• ABS warning light failure    See E7020 ABS
• Electric steering fault    See E7045 ELECTRIC STEERING

Lights failure warning signal (check): the Body Computer contains a check function which, in particular, controls the operation of the exterior lights and lights up the appropriate warning light if a fault is detected; the following systems and/or components are controlled:

• Lights failure: side lights, no. plate, rear fog, direction indicator, brake    See E2010 SIDE LIGHTS / NO. PLATE LIGHTS,    See E2020 DIRECTION INDICATORS / HAZARD WARNING LIGHTS,    See E2021 BRAKE LIGHTS,    See E2031 REAR FOG LAMPS
• Brake lights fuse failure    See E2021 BRAKE LIGHTS
