Description:

This diagnostic trouble code (DTC) UIC 000598.31 is generated if the switch position of clutch pedal switch S72 (transmitted as a CAN message by the TCU) does not match the position of the clutch pedal (ascertained via the signal from clutch pedal potentiometer B65).

Reaction:

When this error occurs, the control unit may limit the functionality of the clutch system, potentially affecting the vehicle’s drivability and safety.

Recommendations:

• Inspect Clutch Pedal Switch and Potentiometer:
  • Check the wiring and connections of the clutch pedal switch (S72) and the clutch pedal potentiometer (B65) for any loose, damaged, or corroded connectors.
  • Measure the signals from both the switch and potentiometer to ensure they match the actual position of the clutch pedal.
• Verify CAN BUS Communication:
  • Ensure that the CAN BUS network is functioning correctly and that there are no communication issues between the TCU and other control units.
  • Inspect the CAN BUS wiring for any signs of damage or interference.
• Replace Faulty Components:
  • If discrepancies are found between the switch and potentiometer signals, replace the faulty clutch pedal switch (S72) or clutch pedal potentiometer (B65).
• Consult Technical Support:
  • If the issue persists after checking and replacing components, contact John Deere technical support for further assistance and potential software updates.

Note:

Intermittent faults in the wiring or connectors can cause signal discrepancies. Ensure a thorough inspection to avoid repeat occurrences. Regular maintenance of the clutch system and its components can help prevent such issues.
