WARNING LIGHTS

The warning lights on the instrument panel may be:

  • directly connected to the input functions/signals in which case the instrument panel does not need to process the signal
  • connected to the input functions/signals through an electronic logic in the instrument panel.
The 'A.B.S.' and 'Air Bag' warning lights are the 'intelligent' type, in other words, they also signal a connection failure with the control unit to which they are connected.

Lights failure summary

The failure signal comes from the integrated services control unit which recognizes:

  • a blown bulb or fuse
  • a break in the electrical wiring or short circuit of a bulb with active control
and sends information on the status of the bulbs to the control panel.The detection of a failure by the control panel is activated with the ignition switch in the ON position and is only recgonized if it persists for longer than 700 ms.The anomaly is stored by the control panel. Once the bulb has been replaced, the anomaly is reset only when the engine is subsequently started.

CONTROL PANEL FUNCTIONS

All control panel functions are handled by a microprocessor and activated when the key is turned to the ON position.The main logical controls carried out by the control panel are as follows.

Control panel check functions

It allows the efficiency of the control panel warning lights to be checked.

The check stage can be activated:

  • automatically, with the ignition in the ON position
  • by means of the appropriate button with the ignition in the ON position and the engine off/started up.
The warning lights come on for six seconds during the check stage.
Any irregularities are signalled by the warning lights staying on for a further fifteen seconds.

Electronic speedometer

It is the analogue type and receives a signal from the A.B.S. 5.3 control unit via the active sensors.The processing of this signal (wheel rpm) depends on the circumference of a conventional tyre and allows the speed to be calculated. is possible to vary the circumference memorized if different sized tyres are used (standard version) via the diagnostic line.

There are four 'repeat' outputs of the signal from the speedometer for other systems:

  • two are used by the air conditioning control unit and he injection/ignition control unit
  • one is for the self-levelling suspension (not available on this model)
  • one is spare.

Boot opening go ahead

The opening of the boot is enabled when:

  • the appropriate button is pressed
  • the vehicle speed is below 2 kph.
The control operates at all times, even with the ignition in the ON position.The panel detects the moment the button is pressed. If the button continues to be pressed, the panel no longer recognizes this condition until the button is next released/pressed.

Milometer

This consists of an LCD which simultaneously displays the total and trip mileage.It processes the signal coming from the A.B.S. control unit and, depending on the tyre circumference, it calculates the mileage.A button is used to zero the trip meter.If the battery is disconnected, the trip meter is zeroed.

Electronic rev counter

It processes the rpm signal coming from the injection/ignition control unit through the electronics in the instrument.

Heated rear windscreen enablement

The control panel processes the rpm signal coming from the injection/ignition control unit.If the speed exceeds 1000 rpm, it sends the integrated services electronic control unit a heated rear windscreen enablement signal.

Fuel gauge

Fuel level is displayed via electronic circuitry inside the panel, which governs the gauge and the reserve warning light.The internal logic 'dampens' the signal preventing fluctuations due to fuel slopping about in the tank.If the fuel gauge sensor wiring is broken, the control panel indicator moves to the start of the scale without the reserve warning light coming on.

The reserve warning light is turned on by the control panel:

  • for 6 seconds (check stage) after the ignition is turned to the ON position.

After the check stage, the warning light should:

  • go out after 30 seconds if the fuel level is higher than the reserve level
  • come on again after 45 seconds if the level is at the reserve level.

Courtesy light timer

This function is activated even with the ignition switched OFF.The courtesy lights are activated when one or more doors are opened and the lights stay on as long as the doors are open, but for no longer than 3 minutes.When the doors are no longer open, provided the 3 minutes have not elapsed, the courtesy light stays on for a further 8 seconds.

If, during these 8 seconds:

  • the ignition key is turned to the ON position
  • the door lock is recognized
the courtesy light is immediately switched off.

Detection of engine running.

The engine is detected as running:

  • when the ignition key is turned from the START to the ON position with the oil pressure sensor already open
  • when the oil pressure sensor opens if the ignition key has already been turned from the START to the ON position
If the oil pressure sensor is faulty, the check system detects that the engine is running 60 seconds after the ignition key has been turned from the START to the ON position.If the vehicle is push started, the check detects that the engine is running 60 seconds after the oil pressure sensor opens.

This is in order to:

  • inhibit the measurement of the oil level with the engine started up
  • time the engine oil pressure warning light.

Engine oil level

The insufficient engine oil level can only be detected once during each engine starting/switching off stage and only using the check button with the engine switched off. This is to avoid incorrect fault signals if the vehicle is not on a level surface or if the engine is switched on/off rapidly.Irregularities detected with the engine switched off are stored so that they can be displayed next time a check request is made in any engine conditions.
The oil level is checked when the engine is cold and with the vehicle level.
To turn off the warning light once the oil has been topped up, a check operation must be carried out.

To measure the oil level again after topping up, it is necessary to:

  • turn the ignition key to the ON position
  • press the check button.

Minimum engine oil pressure

The control panel operating logic switches on the minimum engine oil pressure warning light through the signal coming from the minimum engine oil pressure sensor:

  • key in ON position
  • with the engine running status detected and a fault lasting longer than 10 ms.
The warning light is kept on for a length of time equal to the duration of the fault plus 4 seconds.If the fault lasts less than 10 ms, the warning light only stays on for this time.

Engine coolant temperature gauge

The control panel processes the signal from the engine coolant temperature sensor and operates the gauge and the warning light.

To avoid false readings due to heat fluctuations:

  • the warning light activation is inhibited for 2 minutes from the end of the check stage (6 seconds after the ignition key is turned to the ON position)
  • when the temperature of the engine coolant is within a range from 80° C to 100° C, the gauge always indicates 90° C.
If the coolant temperature sensor is faulty, the coolant temperature gauge pointer is positioned at the beginning of the scale without the warning light coming on. This fault is stored in the control panel and can be identified using the diagnostic equipment.

Brake pad wear

The brake pad wear sensor is always activated from the moment the ignition is switched ON.

A brake pad wear fault is detected:

  • with a wear signal lasting longer than 5 seconds and the brake pedal depressed for the same period
  • with a wear signal lasting longer than 2 seconds, ten consecutive times for the period the ignition is switched ON.
The anomaly is not stored by the control panel but zeroed whenever the car is started up.

Automatic transmission (where fitted)

The automatic transmission control unit notifies the control panel of:

  • the gear lever position
  • the programme setting (SPORT or AUTO)
  • the state of the automatic transmission failure warning light

The following appears on the LCD:

  • the speed engaged, by means of an alternative alphanumerical character (P, R, N, D with the AUTO programme and 1, 2, 3, 4 with the SPORT programme)
  • the programme setting with the two words 'Sport' or 'Auto'.

A warning light in the instrument panel signals:

  • gearbox oil overheating with the warning light on constantly.
  • automatic transmission failure with the warning light flashing.
