UIC 524019.31 – S80 Reverse Drive Lever, PowerZero Switch, Tractor Movement Switch and either the Forward or Reverse Switch are Activated Simultaneously for Too Long a Period

UIC 524019.31 (UIC )

Code: 524019.31

Shortcode:

Description:

This diagnostic trouble code (DTC) UIC 524019.31 is generated when the control unit receives a switch combination from an undefined position of the reverse drive lever (intermediate position) over a longer period of time. The signal of one direction switch (forward travel or reverse travel) is received together with the signal of the tractor movement switch or the power zero switch for too long. This code can also be generated if the reverse drive lever is held in an intermediate position for too long.

Reaction:

When this error occurs, the control unit may prevent the tractor from moving or may limit its functionality to ensure safe operation and prevent potential damage.

Recommendations:

  • Inspect Reverse Drive Lever:
    • Check the reverse drive lever (S80) to ensure it moves smoothly and does not get stuck in an intermediate position.
  • Verify Switch Signals:
    • Confirm that the power zero switch, tractor movement switch, and direction switches are functioning correctly and providing accurate signals.
  • Check Wiring and Connections:
    • Ensure all wiring and connectors related to the reverse drive lever and its switches are secure and free from damage or corrosion.
  • Avoid Intermediate Position:
    • Inform the operator to avoid holding the reverse drive lever in an intermediate position for prolonged periods.
  • Replace Faulty Components:
    • If any switches are found to be faulty, replace them as necessary.
  • Consult Technical Support:
    • If the issue persists and is accompanied by other related faults, contact John Deere technical support for further diagnostics and potential solutions.

Note:

This code is informational and may not indicate a serious issue unless accompanied by related faults.
