Steering Wheel Switch - Raptor
The message center switch is part of the RH steering wheel switch. The switch is comprised of 5 buttons (up, down, OK, back and menu), and 3 buttons (steering, suspension and exhaust) for the optional modes equipped on the Raptor. The message center switch uses different resistance values associated with each button. The SCCM (without adaptive steering) or SASM (with adaptive steering) sends out a reference voltage to the RH steering wheel switch on the input circuit and monitors the voltage drops. The voltage drop varies depending on the resistance of the specific button pressed, providing indication to the SCCM or SASM which button is pressed.
