PTR 524173.16 – Both Clutch Pedals Voltage High

PTR 524173.16 (PTR )

Code: 524173.16



This error code, PTR 524173.16, indicates that the Power Train Reverser (PTR) control unit has detected that the clutch pedal position sensor circuit A voltage is above 4.7 V and circuit B voltage is above 2.35 V for one second, with the sensor reference voltage within range. This can occur due to sensor faults, wiring issues, or control unit problems.


When this error is detected, the PTR control unit may disable the clutch functionality to prevent potential damage or unsafe operation. The system may also display a warning message to alert the operator.
