Expert Technician’s Insight: As a veteran technician, I’ve seen countless drivers chase down phantom issues caused by a failing ECM.

Frequently Asked Questions
Do I need to do any programming myself?
No. This ECM is a plug-and-play solution. We handle all the programming for you before we ship the part. All you need to do is provide your vehicle’s VIN at checkout, and it will arrive ready to be installed.
Where do I find my vehicle’s VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found in several places: on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Is this the correct part for my vehicle?
This module, service number 12630457, is interchangeable with several other part numbers listed in the description. The best way to ensure a perfect match is to provide your VIN. Our programming process guarantees that the module we send is 100% compatible with your specific vehicle’s configuration.
What about my vehicle’s anti-theft system (VATS/Passlock)?
In many cases, after installation, you may need to perform a simple security relearn procedure. This can typically be done without any special tools and involves a sequence of key turns. This process syncs the new ECM with your vehicle’s existing anti-theft system.
Will this fix my check engine light?
If the check engine light was caused by a faulty ECM (e.g., internal processor failure codes), then this part will resolve the issue. However, if the light is on due to other problems like a bad sensor or an exhaust leak, those issues will still need to be addressed separately.
What happens after I place my order?
After you purchase the ECM, please send us your vehicle’s VIN. We cannot ship your part until we receive the VIN, as the programming is a critical part of your order. Once programmed and tested, we will ship it directly to you.
