Get Your Vehicle Running Right Again
Is your truck, van, or SUV suffering from frustrating issues like a persistent check engine light, stalling, a no-start condition, or erratic engine behavior? A failing Engine Control Module (ECM) is often the culprit, acting as a faulty brain for your vehicle’s most critical systems. This Programmed 12704475 ECM is the definitive solution, designed to restore your vehicle’s performance, reliability, and communication. We take the guesswork out of the repair by pre-programming the module to your specific Vehicle Identification Number (VIN) with the latest GM software updates before it ever leaves our facility.

Expert Insight: Why VIN Programming is Non-Negotiable
Think of your ECM as the central command center. It’s not a one-size-fits-all part. A module from another vehicle, even an identical model, won’t work correctly because it’s not calibrated for your engine, transmission, and specific options. Our professional VIN programming service ensures this Programmed 12704475 ECM speaks the correct digital language for your vehicle. This prevents a host of future problems, saves you from frustrating dealership visits, and is the key to a successful, long-lasting repair.
Frequently Asked Questions
What information do I need to provide?
After you complete your purchase, you must provide us with your vehicle’s 17-digit VIN. We cannot ship your order until we have this information, as it is required for programming the module correctly.
Will I need to do anything after installation?
In many cases, the vehicle will start and run correctly. However, if the vehicle does not start, a Vehicle Theft Deterrent (VTD) relearn procedure must be performed. This syncs the new ECM to your vehicle’s anti-theft system. This procedure requires a professional GM diagnostic tool (like Tis2web/Techline Connect) and is the responsibility of the installer.
Are other relearn procedures necessary?
Depending on your specific vehicle, additional procedures like a crankshaft position variation relearn or injector flow rate programming may be needed to achieve optimal performance. These are standard procedures after replacing an ECM and should be performed by a qualified technician.
Is this a plug-and-play part?
Because we pre-program it to your VIN, it is as close to plug-and-play as possible. However, due to vehicle security systems, the VTD relearn mentioned above is a common and necessary final step for the installer. This Programmed 12704475 ECM eliminates the need for programming from scratch, saving significant time and money.
How do I know if this ECM fits my vehicle?
Please refer to the detailed fitment list on this page. This module fits a wide variety of GM trucks, vans, and cars. Matching one of the listed part numbers (12704475, 12692069, 12680656, etc.) ensures compatibility.
What does the one-year warranty cover?
The warranty covers the replacement of the module itself should it fail within one year of the purchase date. It covers the part, not labor or diagnostic costs.
