Is Your Cadillac or GM Vehicle Experiencing Critical Engine Problems?
A failing Engine Control Module (ECM) can be the source of immense frustration, causing unpredictable stalling, a persistent Check Engine Light, poor fuel economy, or even preventing your vehicle from starting at all.

Simply provide your VIN after purchase, and we’ll handle the rest, shipping you a module that’s ready for installation.
Frequently Asked Questions
Is this part truly plug-and-play?
Yes, for most vehicles. We program the ECM to your VIN, which handles the majority of the setup. However, on some GM models, a simple Security Relearn procedure (often requiring only the ignition key and a few minutes) or a Crankshaft Variation (CASE) Relearn may be necessary after installation. These are standard procedures that can be done by most mechanics or with a capable scan tool.
How do I provide my VIN?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot program and ship the module without it. You can find your VIN on your vehicle’s dashboard (visible through the windshield) or on your registration and insurance documents.
Is this a new part?
No, this is a high-quality, used OEM (Original Equipment Manufacturer) computer that has been carefully sourced from a salvaged vehicle. We test each unit to ensure it is fully functional before programming it for you.
What does “programmed” or “flashed” mean?
“Programming” or “flashing” is the process of loading the correct factory software and calibration files onto the ECM for a specific vehicle. We use your VIN to access the exact software your car needs from GM’s database, ensuring perfect compatibility and performance.
Will this fit vehicles other than the Cadillac SRX?
Absolutely. This ECM is compatible with a wide range of GM models and years as listed in the fitment chart, including the Chevy Equinox, GMC Acadia, Buick LaCrosse, and many others. Please check the detailed fitment list on this page to confirm compatibility with your specific vehicle.
