An Expert’s Note on Programming
Many ECMs sold online are ‘blank,’ which means they require expensive, specialized dealer tools to be programmed *after* they are installed. This creates a hidden cost and a major roadblock for both DIY installers and professional shops. We eliminate this critical hurdle by performing the programming for you. By using your VIN, we ensure all factory-specific calibrations are correctly loaded. This isn’t just about making the engine start; it’s about restoring the precise performance and fuel efficiency engineered by GM for your premium vehicle. This programmed 12674052 engine control module is a complete solution, not just a part.
Frequently Asked Questions
What do I need to do after placing my order?
After your purchase is complete, you must provide us with your vehicle’s 17-digit VIN. We cannot program or ship your module without this information. It is essential for loading the correct software for your specific vehicle.
Will I need to do anything after installation?
In many cases, a ‘Vehicle Anti-Theft System’ (VATS) relearn is required. This is a standard security procedure that syncs the new ECM to your vehicle’s keys and anti-theft system. This may require a professional scan tool with GM programming capabilities. Other procedures, like a crankshaft variation relearn, may also be necessary depending on your specific model.
Is this a brand new part?
This is a high-quality, fully tested engine control module that has been meticulously inspected and prepared to meet or exceed original equipment specifications. The critical step is the fresh, VIN-specific programming we perform before shipping.
How can I be sure this fits my vehicle?
Please review the detailed fitment list on this page. The most reliable way to ensure compatibility is by matching the part number on your original ECM to 12674052 or one of the alternate part numbers listed. Providing your VIN during checkout allows us to double-check and confirm the correct application.
Why is VIN programming so important?
VIN programming loads all the specific software and calibration files for your vehicle’s engine, transmission, tire size, gear ratios, and emissions equipment. A module without the correct programming will not function properly, leading to poor performance and error codes. Our service ensures your programmed 12674052 engine control module works correctly right out of the box.
What kind of warranty is included?
This unit is backed by our one-year replacement warranty, giving you confidence and peace of mind in your repair.
