Clutch pedal normal sensor open circuit, or short circuit to ground.
• Check wiring (to clutch pedal normal sensor) • Check connectors (to clutch pedal normal sensor) • Check clutch pedal normal sensor • Measure the sensor voltage between signal and ground • Check clutch pedal mechanism
What you'll see
• Changing split gear is inhibited • Activation of clutch dependent PTO (e.g. PTO-EG) is inhibited, when engine is running • Some engine speed control modes ("PTO-modes") are inhibited • Cruise control is disabled (if the vehicle is not equipped with clutch by wire) • Adaptive Cruise control is disabled (if the vehicle is not equipped with clutch by wire)
System reaction
Amber Cruise Control malfunc.
Diagnostic depth
Impermissible signal from the clutch pedal normal sensor. The sensor voltage level is too low. The clutch sensor has an open circuit, or is short circuit to ground.
• Defect wiring - open circuit on clutch signal (pin C14) - open circuit on clutch supply (pin C32) - short circuit to ground • Defect connectors • Defect clutch pedal normal sensor (potentiometer) • Mechanically defect clutch pedal mechanism (causing clutch pedal sensor to reach an impermissible position)
