Frequently Asked Questions
Is this ECU plug-and-play, or does it need programming?
This ECU is a used OEM unit and will require VIN programming and immobilizer synchronization by a qualified technician or dealership before it will start and run your vehicle. It is not a simple plug-and-play install.
How do I confirm this is the correct part for my vehicle?
You must match the part number on your original ECU. The number listed in our specifications is an example. Locate the label on your current ECU (usually a white sticker with a barcode) and compare the main part number (e.g., 89661-XXXXX) to ensure compatibility. Providing your VIN during checkout helps us double-check.
What is your testing process for ECUs?
We bench-test our ECUs for power and communication. They are pulled from running vehicles. However, a final functional test can only be performed after proper installation and programming in the intended vehicle, which is why we offer a 30-day return policy.
