Product testing steps
1. **Prepare**: Ensure the excavator is turned off and safely secured. Disconnect the battery to avoid

electrical accidents.

2. **Inspect**: Check the ECU for physical damage or loose connections.

3. **Connect Diagnostic Tool**: Use a diagnostic tool recommended by the excavator's manufacturer.

Connect it to the ECU according to the tool's instructions.

4. **Read Codes**: Use the diagnostic tool to read any error codes (DTCs) stored in the ECU. These

codes indicate potential problems with the ECU or connected systems.

5. **Check Live Data**: View live data parameters such as sensor readings and system voltages. Ensure

they are within normal ranges.

6. **Functional Tests**: If possible, perform tests to activate components or simulate sensor inputs.

Verify that the ECU responds correctly without delays or errors.

7. **Reset (if needed)**: Reset the ECU if recommended by the manufacturer, especially after repairs

or replacements.

8. **Document**: Keep a record of all tests, codes, and results for future reference.

9. **Consultation**: If issues persist, consult with the manufacturer's technical support or a qualified

technician for further assistance.

By following these steps, you can effectively test the ECU of an excavator to ensure it's working properly

and diagnose any potential problems.
