Description:

This diagnostic trouble code (DTC) is issued when Hotkey 3 remains continuously actuated for more than 60 seconds during initialization or is registered as “actuated” for more than 10 minutes during operation. The issue may arise from a mechanically stuck button, sensor faults, or software issues that misread the key’s status.

Reaction:

To prevent unintended operations, the system may disable Hotkey 3 and issue alerts to notify the operator of the malfunction, which can impact user interface functionality.

Recommendations:

• Check for Mechanical Issues: Inspect Hotkey 3 for any signs of sticking and resolve any physical obstructions.
• Sensor Evaluation and Repair: Test sensors involved in detecting actuation and recalibrate or replace faulty sensors.
• Software Diagnostics and Update: Conduct software diagnostics to detect any anomalies affecting key recognition and update or correct software as required.

Note:

Reliable function of control unit keys is essential for smooth operation. Regular maintenance and immediate repair of any detected issues are crucial for maintaining equipment functionality.
