Description:

This diagnostic trouble code (DTC) indicates a fault with Hotkey 5 on the control unit. The error is triggered if Hotkey 5 remains continuously actuated for more than 60 seconds during initialization or if it is registered as “actuated” for more than 10 minutes during operation. This could be due to a stuck button, sensor errors, or software malfunctions that misinterpret the key’s status.

Reaction:

The system may disable the function of Hotkey 5 or issue alerts to notify the operator of the fault, potentially affecting user interface efficiency and control accessibility.

Recommendations:

• Inspect Hotkey for Physical Sticking: Check if the hotkey is physically stuck and address any mechanical issues.
• Calibrate or Replace Faulty Sensors: If the key is not stuck, test the sensors responsible for detecting key actuation and recalibrate or replace if necessary.
• Software Diagnostic and Correction: Run diagnostics to identify any software issues that may be incorrectly registering key actuation and apply software updates or patches if available.

Note:

Ensuring all control unit keys are functioning correctly is essential for effective machine operation. Regular maintenance and prompt attention to faults can prevent operational disruptions.
