The CPP switches indicate the state of the clutch pedal. The CPP switch A is a normally open switch that indicates clutch disengagement (bottom of travel). The CPP switch B is a normally closed switch that indicates clutch engagement (top of travel). The application and release of the clutch pedal disables the speed control system, the cold idle kicker, or the power take-off (PTO) system, if enabled.
