PTH 523590.13 – Machine Drive Forward Pedal Out of Calibration

PTH 523590.13 (PTH )

Code: 523590.13



This fault code indicates that the forward pedal sensor is out of calibration, which can affect the accuracy of the pedal response and overall performance.


When this error is detected, the equipment may experience improper or erratic forward pedal response, affecting driving behavior. The system logs the fault and may take corrective actions to prevent unsafe conditions.


System Calibration (Power Train Hydrostatic Control Unit – PTH):

  • Perform a system calibration for the PTH control unit to ensure accurate sensor readings.
  • Follow the manufacturer’s guidelines for calibration procedures.

Inspect Forward Pedal Sensor (B11):

  • Check the forward pedal sensor for proper operation.
  • Ensure the sensor is not damaged and is functioning correctly.
  • Verify all electrical connections are secure and free from corrosion.

Test Power Train Hydrostatic Control Unit (PTH):

  • Perform diagnostic tests on the control unit to identify any faults.
  • Ensure all electrical connections to the control unit are secure and free from corrosion.

Update Control Software:

  • Ensure the control unit software is up-to-date with the latest calibration data and improvements.

Consult Technical Support:

  • If the fault persists, contact technical support for further diagnostics and possible re-calibration or replacement of the sensor.

Monitor System Performance:

  • After addressing the issue, monitor the forward pedal system to ensure normal operation and that the fault does not reappear.


Regular calibration of the forward pedal sensor and maintenance of the associated wiring can help prevent this fault. Ensuring proper calibration procedures are followed during setup and routine maintenance is crucial for reliable operation.
