Frequently Asked Questions
What do I need to do after I purchase?
After you complete your purchase, you must send us your vehicle’s 17-digit VIN (Vehicle Identification Number). We cannot ship your part until we receive the VIN, as we use it to program the module specifically for your van.
Is this a difficult part to install?
The physical installation is straightforward for anyone with basic mechanical skills. However, after installation, you will likely need to perform a security relearn procedure (also known as a key relearn or anti-theft relearn). This procedure syncs the new ECM with your vehicle’s keys and can often be done without any special scan tools. Instructions are widely available online for your specific model.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the original ECM, then yes, this part will resolve the issue. It’s crucial to ensure a proper diagnosis was performed to confirm the ECM is the root cause of your problems before ordering.
Where can I find my VIN?
Your VIN can be found on a metal plate on the driver’s side dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Does this part fit other vehicles besides the Express van?
Yes, this versatile ECM is compatible with a wide range of GM trucks, vans, and cars from roughly 2011-2016, including the Silverado/Sierra 2500/3500 with the 6.0L engine, Cruze, Sonic, and Volt. Please carefully review the compatibility list provided in the product details to ensure it matches your specific vehicle and options.
