DESCRIPTION
The control panel is installed behind the steering wheel.It is connected to the CAN and includes 4 gauges produced using stepper motors.
The control panel display is available in two versions depending on the vehicle's on-board technological specifications:
- Multifunction display - LOW specifications
- Reconfigurable multifunction display - HIGH specifications
In both configurations a single instrument contains:
- electronic speedometer
- fuel level gauge (with insufficient fuel level warning light)
- engine coolant temperature gauge (with overheating warning light)
- electronic rev counter
- display (available in two different versions)
- warning lights
A buzzer inside the instrument can produce signals of different intensities to perform the following functions:
- alarm/warning/danger signals
- parking sensor signalling
- Seat Belt Reminder
- direction indicators/hazard warning lights acoustic signals
- push button roger beep
The instrument panel is a CAN node through which information is exchanged with the Body Computer and with the other electronic units.
- Speedometer: the function of the speedometer includes displaying the vehicle speed in the instrument panel: this information comes from the ABS control unit and Powertrain Control Module, via the Body Computer.
- Engine rpm: this function involves the display on the instrument panel of the engine rotation speed by means of the message sent via the CAN from the Powertrain Control Module.
- Milometer: this function involves the display and memorising of the total and trip mileage: mileage information is processed by the Body Computer by means of a counter that is sent to the instrument panel via the CAN.The trip counter that forms part of the Trip Computer can be reset using the special TRIP button for the right steering column switch unit lever.
- Fuel level: the Body Computer receives the signal from the sensor built into the pump assembly inside the fuel tank and processes it to guarantee suitable filtering/damping for the instrument panel gauge; it also controls the lighting of the reserve warning light. The circuit is capable of detecting a fault in the wiring or in the sensor and providing the instrument panel with a suitable reading: if there is a system malfunction, the pointer is at the start of the scale and the reserve warning light flashes.
- 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 Powertrain Control Module. The temperature reading is always guaranteed, even in extreme operating conditions.
- Minimum engine oil pressure: this function involves the display in the instrument panel of the engine oil pressure warning light by means of the message sent via the CAN from the Powertrain Control Module.
- Brake pad wear status: this function involves the dedicated warning light coming on: the Body Computer detects the brake pad wear status when braking (signal from the brake pedal) in a prolonged manner (occasional signals are ignored).
- Handbrake applied: the Body Computer acquires the handbrake status from a special switch and notifies the instrument panel of activation via the CAN.The function turns on the low brake fluid level warning light in the instrument panel.A buzzer is also activated if this signal is associated with the exceeding of a set speed threshold.
- Insufficient brake fluid: this function involves the insufficient brake fluid level warning light in the instrument panel coming on; the signal sent by the Body Computer via the CAN.
- Inertia switch status: the Body Computer receives a signal from the switch and communicates activation via the CAN to the instrument panel, which emits a signal (warning light + message).

The general fault signal summarises the faults detected by a set of systems and components:
- Fuel cut off function intervention
- Engine oil pressure sensor failure
- Parking sensor failure
- Rain sensor failure
- Dusk sensor failure
- Anti-crush safety function failure
- Exterior lights failure
Exterior lights failure: The Body Computer contains a check function that specifically monitors exterior light operation and turns on a warning light if a fault is detected: side lights, number plate, rear fog, direction indicator and brake light faults (including brake light fuse failure).
