Frequently Asked Questions
What do I need to do after installing this ECM?
Upon installation, the vehicle may not start until a security or theft deterrent relearn is performed. This procedure syncs the new ECM with your vehicle’s anti-theft system. Additional procedures, such as a crankshaft variation relearn, may also be necessary. These are the responsibility of the installer and require a compatible professional scan tool or GM’s programming software.
How do I provide my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your module without it. Please double-check it for accuracy to ensure a perfect match.
Is this a brand new part?
This is a quality-inspected, genuine GM component that has been professionally programmed by our technicians to be ready for installation in your vehicle. It is guaranteed to function to original equipment specifications.
Will this fix my check engine light?
If your vehicle’s check engine light is on due to an internal ECM failure (often indicated by codes like P0601 through P0606), this part is the correct solution. However, a check engine light can be caused by many other issues. We always recommend a proper diagnosis by a qualified technician before ordering.
