SIDC is available in different variants, depending on the car's equipment level.
The buttons are instant and the INFO knob has 18 distinct positions with spring-return pushbutton function.
SIDC has limited electronics and communicates on a wired link to ICM using PWM signals (square wave).
On certain markets, there are LEDs in the SIDC used by the PPS control module to indicate passenger airbag ON/OFF.
SIDC has a 12-pin connector.
