Description:

This diagnostic trouble code is triggered if the key for engaging/disengaging front-wheel drive automatic mode 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. This key plays a vital role in switching the vehicle’s front-wheel drive between manual and automatic modes for optimal traction and control.

Reaction:

If the front-wheel drive automatic mode key remains actuated beyond the specified durations, the control unit may disable the functionality associated with automatic mode to prevent unintended or unsafe operations, potentially affecting vehicle traction control.

Recommendations:

• Inspect Hotkey Mechanism: Check the physical condition of the front-wheel drive automatic mode key 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 automatic mode key. Ensure it accurately registers presses and releases.
• Check Electrical Connections: Ensure that the electrical connections to the automatic mode key are secure and free from corrosion or damage.
• Update Control Software: Make sure the control unit software is current, as updates may resolve issues related to hotkey management.
• Replace Faulty Components: If the key 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 key operation through comprehensive testing.

Note:

Ensuring the functionality of the front-wheel drive automatic mode key is crucial for maintaining optimal vehicle control. Regular inspection and maintenance of the key mechanisms can prevent faults and ensure reliable control input recognition.
