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 depressed, the SID unit sends Night panel ON information out on the bus.

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

The tachometer, fuel gauge, turbo pressure gauge and temperature gauge needles return 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 is above 5500 rpm (manual gearbox) or 5900 rpm (automatic transmission).

Fuel gauge, turbo pressure gauge and temperature gauge if there is less than 15 litres of fuel in the tank.

Fuel gauge, turbo pressure gauge and temperature gauge if engine temperature is above 120°C (248°F).

Fuel gauge, turbo pressure gauge and temperature gauge if intake manifold pressure is above 210 kPa (automatic transmission) or 216 kPa (manual gearbox).

The selector lever display lights up if the selector lever is NOT in position D.


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.

Diagnostics

The function has its own diagnostics in the sending system.
