DSM 523523.10 — Hotkey 13, Fault

DSM 523523.10 (DSM )

Code: 523523.10



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.


If the hotkey remains actuated beyond the specified durations, the control unit may interpret this as a fault condition. This could lead to disabling the hotkey functionality or other related features to prevent unintended operations.


  • Inspect Hotkey Mechanism: Check the physical condition of Hotkey 13 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 Hotkey 13. Ensure it is correctly registering presses and releases.
  • Check Electrical Connections: Ensure that the electrical connections to Hotkey 13 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.


Regular maintenance of control interfaces like hotkeys is essential for preventing operational faults. Timely inspection and repair of hotkey mechanisms can ensure reliable and accurate control input recognition.
