DSM 523525.10 — Hotkey for Load/Depth Adjustment, Fault

DSM 523525.10 (DSM )

Code: 523525.10



This diagnostic trouble code is triggered if the key remains continuously actuated for more than 60 seconds during initialization (after the ignition has been switched on), or if the key is registered as “actuated” for more than 10 minutes during operation.


When the hotkey for load/depth adjustment remains actuated beyond the specified durations, the control unit may disable the functionality associated with load/depth adjustment to prevent unintended or unsafe operations.


  • Inspect Hotkey Mechanism: Check the physical condition of the load/depth adjustment hotkey for signs of sticking, damage, or wear that could cause it to remain actuated.
  • Test Hotkey Functionality: Use diagnostic tools to verify the proper operation of the load/depth adjustment hotkey. Ensure it is correctly registering presses and releases.
  • Check Electrical Connections: Ensure that the electrical connections to the load/depth adjustment hotkey are secure and free from corrosion or damage.
  • Update Control Software: Ensure that the control unit software is up-to-date to include any fixes or improvements for hotkey management.
  • Replace Faulty Components: If the hotkey or its associated wiring and connectors are found to be 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 hotkey operation through comprehensive testing.


Maintaining proper functionality of control hotkeys is essential for accurate equipment operation. Regular inspection and maintenance of hotkey mechanisms can prevent faults and ensure reliable control inputs.
