DSM 523533.10 — Transport Lock Button (EICVs), Fault

DSM 523533.10 (DSM )

Code: 523533.10



This diagnostic trouble code is triggered if the transport lock button for Electrohydraulic Integrated Control Valves (EICVs) remains continuously actuated for more than 60 seconds during initialization (after the ignition has been switched on), or if the button is registered as “actuated” for more than 10 minutes during operation. The transport lock is essential for securing equipment during transport to prevent accidental activation.


If the transport lock button remains actuated beyond the specified durations, the control unit may disable the functionality associated with the transport lock to prevent unintended or unsafe operations, potentially affecting the secure transport of equipment.


  • Inspect Button Mechanism: Examine the physical condition of the transport lock button for signs of sticking, damage, or wear that could cause it to remain actuated.
  • Test Button Functionality: Use diagnostic tools to verify the proper operation of the transport lock button. Ensure it accurately registers presses and releases.
  • Check Electrical Connections: Ensure that the electrical connections to the transport lock button are secure and free from corrosion or damage.
  • Update Control Software: Confirm that the control unit software is up-to-date, as updates may include fixes or improvements for button management.
  • Replace Faulty Components: If the button or its associated wiring and connectors are faulty, replace them with new or known-good parts.
  • Perform System Reset: After resolving the issue, reset the control unit to clear the fault code and verify normal button operation through comprehensive testing.


Maintaining the proper functionality of the transport lock button is essential for safe equipment transport. Regular inspection and timely maintenance of the button mechanisms can prevent faults and ensure reliable control inputs.
