Frequently Asked Questions
Q1: How long does it take to install the ECM on machine?
  • Physical Installation: 15-30 minutes. The unit is typically secured by 4 bolts on the cool side of the engine.
  • Programming & Testing: 30-60 minutes.
  • Pro Tip: If the ECM is pre-programmed by us based on your machine's serial number, it is essentially "Plug & Play." If not, you will need a ET (Electronic Technician) tool to flash the software, which takes additional time. We recommend professional installation to ensure correct parameter synchronization.
Q2: How to determine if the ECM is faulty and needs replacement?
  • 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.
Q3: What's your payment method?

Our payment methods include T/T, L/C, PayPal, etc.

Q4: Do you have stock?

Step-by-Step Testing Guide
Pro-Tip: HEUI (Hydraulic Electronic Unit Injection) systems are extremely sensitive to contamination. A single speck of dust can cause premature failure.
  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.

Before replacing the ECM, always check the fuses, main relays, and ground connections. In many cases, a faulty ground wire or low battery voltage mimics an ECM failure.
