Description:

This error code indicates a malfunction within the engine speed control module, specifically involving the ECO push button. The problem is characterized by both the ON and OFF contacts of the button showing the same value, which typically suggests that the switch might be stuck or that there is a defect in the circuit that manages these contacts.

Reaction:

Due to this detected conflict, the control unit has disabled the function associated with the ECO push button to prevent potential issues that could arise from incorrect or unpredictable engine performance settings.

Recommendations:

• Inspect the ECO Push Button: Check the button for any physical blockages, wear, or damage that could cause it to remain in a single state. Ensure that it can freely move between ON and OFF positions.
• Evaluate Electrical Circuitry: Assess the electrical circuitry associated with the ECO push button for any anomalies such as shorts, faulty wiring, or damaged components that could result in both contacts showing the same value.
• Rectify or Replace Faulty Components: If any part of the button mechanism or circuitry is found to be faulty, repair or replace these components to ensure the button functions as intended.
• Functionality Testing of the Button: Once repairs have been made, test the ECO push button thoroughly to confirm that it can accurately switch between ON and OFF without any conflicts.
• Reset the System and Verify Operations: After resolving the issue, reset the control system to clear any error statuses. Conduct a comprehensive test to verify that the button’s functionality is fully restored and that it correctly influences the engine’s operation settings.

Note:

Regular inspections and maintenance of control module switches and circuits are essential for preventing malfunctions that could affect the operational efficiency and safety of machinery. Addressing such issues promptly ensures that equipment remains reliable and performs optimally under various working conditions.
