- The ET diagnostic tool cannot communicate with the ECM, or it displays a "Module Not Responding" error. This is a critical sign of internal hardware failure.
- Active fault codes related to internal memory (EEPROM) or voltage reference issues that persist after checking the wiring harness often indicate ECM failure.
- Sudden engine stalling, severe power loss (Limp Mode), or persistent misfiring (missing injector driver signals) after sensors and harnesses have been ruled out.
- Visible signs of overheating (burning smell), water ingress, corrosion, or broken pins on the connector headers.
- Prepare: Ensure the excavator is turned off and safely secured. Disconnect the battery to avoid electrical accidents.
- Inspect: Check the ECU for physical damage or loose connections.
- Connect Diagnostic Tool: Use a diagnostic tool recommended by the excavator's manufacturer. Connect it to the ECU according to the tool's instructions.
- 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.
- Check Live Data: View live data parameters such as sensor readings and system voltages. Ensure they are within normal ranges.
- Functional Tests: If possible, perform tests to activate components or simulate sensor inputs. Verify that the ECU responds correctly without delays or errors.
- Reset (if needed): Reset the ECU if recommended by the manufacturer, especially after repairs or replacements.
- Document: Keep a record of all tests, codes, and results for future reference.
