Description:

This diagnostic trouble code (DTC) is triggered for Hotkey 1 when it remains continuously actuated for more than 60 seconds during initialization or is registered as “actuated” for more than 10 minutes during operation. Issues may stem from a stuck key, faulty sensors, or software problems misinterpreting the key’s status.

Reaction:

The system may limit the functionality of Hotkey 1 to prevent unintended actions and alert the operator to the issue, impacting user control capabilities.

Recommendations:

• Mechanical and Sensor Inspection: Investigate Hotkey 1 for physical and sensor-related issues and correct any detected faults.
• Software Troubleshooting: Address any software-related issues that may be incorrectly registering the key’s actuation and perform necessary updates.
• Ensure Key Functionality: Regularly check all hotkeys for responsiveness and correct functionality as part of routine maintenance.

Note:

The effective operation of control unit hotkeys is vital for accurate and efficient machine use. Regular maintenance and swift resolution of any faults are essential to maintain control unit effectiveness.
