Outside temperature sensor
The temperature sensor sends information on the current outside temperature to the SID unit.
Steering wheel controls
There are 7 control buttons on the steering wheel. One is used to activate the horn, the others to control the audio system. When a button is pressed, the
SID reads a voltage level.
On cars without an audio system, only the horn button is filled.
Coolant level sensor
The sensor detects a low coolant level and informs the SID unit.
Washer fluid level sensor
The sensor detects a low washer fluid level and informs the SID unit.
Filament monitor
The filament monitor tests the front headlamp function and passes information to the SID unit.
Rheostat
The SID unit uses the current rheostat setting to control the button and display lighting on the SID unit.
The rheostat value is output to the bus for use in adjusting the control and instrument lighting.
Interior light sensor
The light sensor is integral with the SID unit and used to measure the light intensity in the vehicle. The SID unit uses the current light reading and
rheostat value to determine the intensity of the display lighting.

The display lighting value is output to the bus to control the light intensity of the displays.
