NIGHT PANEL

NIGHT PANEL

The SID incorporates a NIGHT PANEL function which turns off the instrument and display lighting when activated.

When the NIGHT PANEL button on the SID unit is pressed, the SID unit sends a "NIGHT PANEL ON" signal to the bus.

The main instrument unit then switches off the instrument and display lighting.

The tachometer, fuel gauge and temperature gauge needles go to their zero positions when the lighting has been turned off.

Only the speedometer (up to 140 km/h (90 mph)), indicator lamps and warning lamps stay on.

The following gauges/displays return to their normal state under the following circumstances:




• The speedometer's high-speed part of the scale if the speed of the car exceeds 134 km/h (86 mph).

• The tachometer if engine speed exceeds 4000 rpm.

• The fuel gauge and temperature gauge if the fuel level in the tank is below 15 litres.

• The fuel gauge and temperature gauge if engine temperature exceeds 112°C (234°F).


If the NIGHT PANEL button is pressed a second time, the SID unit sends out a "NIGHT PANEL OFF" signal on the bus. Acting on this information, the main instrument unit first resets all the gauges to normal display and then turns on the lighting.

Diagnosis

The function has its own diagnostics in the sending system.
