Cabin light intensity: Notes
When the light intensity in the cabin exceeds a certain level, the SID unit sends out Rheostat value 0% on the bus.
To increase bulb life, the main instrument unit's control module then turns off the following instrument lighting:
- Speedometer
- Turbo pressure gauge
- Tachometer
- Coolant temperature gauge
- Fuel gauge
- Selector lever indicator (automatic transmission)
For better visibility, the brightness of the indicator and warning lamps is set to two different levels. Low brightness at night and high brightness during the day.
The SID unit sends information on cabin light intensity, unit Lux, to the bus and at a predetermined level the main instrument unit's control module changes the brightness of the following lamps.
Common to all these lamps is that they are supplied with current (+15 circuit) from the main instrument unit and grounded through its control module.
- Fuel reserve indicator lamp
- INFO DISPL lamp
- Central warning lamp
- Rear fog light
- LH direction indicators
- RH direction indicators
- Selector lever indicator (segment)
The following lamps are supplied with current from the component concerned and grounded via the main instrument unit. The brightness of the lamps changes in the same way as the other warning and indicator lamps.
- Main beam
- Lights on
- CRUISE
The following lamps are supplied with PWM current and grounded in via the TCM control module. The brightness of the lamps changes in the same way as the other warning and indicator lamps.
- SPORT
- WINTER
