Restore Your Vehicle’s Performance and Reliability
Is your Buick or Cadillac suffering from frustrating and unpredictable engine problems? A persistent check engine light, sudden stalling, rough idling, or a complete no-start condition can often be traced back to a failing Engine Control Module (ECM). Instead of dealing with the high costs and complexities of a dealership repair, this genuine OEM Programmed 12592124 ECM offers a direct, reliable, and cost-effective solution to get you back on the road with confidence.
Common Symptoms & Your Solution
A faulty ECM can manifest in numerous ways, making your vehicle unreliable and unsafe. If you’re experiencing any of the following, this module is the definitive fix:

Expert Insight: Why VIN Programming is Non-Negotiable
As a technician with over two decades of experience, I’ve seen countless vehicle issues caused by improperly matched control modules. Simply installing a used ECM from another car won’t work. Modern vehicles use a complex network where the ECM must have the correct VIN, software, and security credentials to communicate with the Body Control Module, Transmission Control Module, and anti-theft system. Our mandatory VIN programming service isn’t just a feature; it’s the core of a successful repair. It ensures every parameter is correct, preventing immobilizer lockouts and system conflicts, and making your installation as seamless as possible.
Don’t let a faulty computer keep your car off the road. By providing us with your VIN at checkout, you ensure that you receive a fully compatible, updated, and ready-to-install Programmed 12592124 ECM. It’s the smart, professional-grade solution to restore the smooth, reliable performance you expect from your vehicle.
Frequently Asked Questions
Where do I provide my VIN?
After you complete your purchase, you will need to send us your vehicle’s 17-digit VIN. You can typically add this as a note during checkout or send it to us in a message referencing your order number. We cannot ship the part until we have this information.
Is any additional programming required after installation?
In most cases, no further programming is needed. However, some vehicles may require a simple security relearn procedure (often called a CASE relearn or anti-theft relearn) which can typically be done without special tools. Instructions for this are widely available online for your specific model.
Why should I choose a used OEM part over a new aftermarket one?
Used OEM (Original Equipment Manufacturer) parts are the same components your vehicle was built with at the factory. They offer superior quality, fitment, and electronic compatibility compared to many aftermarket alternatives. Our units are thoroughly tested to ensure they function correctly.
How do I know if this ECM will fit my vehicle?
Please check the fitment list provided in the description. This part is compatible with specific makes, models, and engine options. The best way to confirm is to match your original part’s service number to one of the compatible numbers listed (12581144, 12588472, 12592124, 19260507).
What is the programming process?
Once we receive your VIN, our technicians use professional-grade tools and official GM software to load the correct calibration file for your exact vehicle configuration. This includes engine and transmission parameters, emissions settings, and security information.
