Steering Wheel Switches
WARNING: This page is about a different variant/trim than selected.
The RH steering wheel switch consists of a series of resistors. Each steering wheel switch function corresponds with a specific resistance value within the switch. The SCCM sends out a 5-volt reference voltage to the RH steering wheel switch on the input circuits and monitors the voltage drop when a button is pressed. The voltage drop varies depending upon the resistance of the specific button pressed, providing indication to the SCCM which switch is pressed.
