Frequently Asked Questions
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to load the exact software and calibrations your specific vehicle requires. This includes information about your engine, transmission, tire size, and other factory options. Programming the ECM to your VIN is critical for proper function and avoids compatibility issues.
Is this part difficult to install?
The physical installation is typically straightforward, involving disconnecting the battery and swapping the old module with the new one. However, most GM vehicles will require a security relearn procedure after installation to allow the vehicle to start. This procedure can often be done without special tools and instructions are readily available online.
Will this ECM fix my check engine light?
If the check engine light is caused by a faulty ECM, then yes, this part will resolve the issue. It’s crucial to have a proper diagnosis to confirm the ECM is the root cause and not another sensor or component.
What is a security relearn procedure?
This is a process that syncs the new ECM with your vehicle’s anti-theft system and ignition keys. For many GM vehicles, it involves a simple sequence of turning the key to the ‘ON’ position for 10-15 minutes, then off, and repeating this two more times.
Is this a new or used part?
This is a high-quality, tested, and verified original equipment part that has been professionally prepared and programmed for your vehicle, ensuring reliable performance and compatibility.
