Get Your Truck Back to Peak Performance
Is your Silverado, Sierra, or other GM vehicle suffering from frustrating issues like stalling, rough idling, no-start conditions, or a persistent Check Engine Light? A failing Engine Control Module (ECM) is often the culprit, disrupting communication between critical engine components and leaving you stranded. This isn’t just an inconvenience—it’s a blow to your truck’s reliability. This precision-programmed ECM is the definitive solution to restore your vehicle’s power, efficiency, and dependability, getting you back on the road with confidence.
Common Symptoms & Your Solution
A faulty ECM can manifest in numerous ways, often triggering Diagnostic Trouble Codes (DTCs) such as P0601 (Internal Control Module Memory Check Sum Error), P0606 (ECM/PCM Processor Fault), or other communication errors. You might also experience poor fuel economy, erratic shifting, or a complete failure to start. This unit is the direct, reliable fix.

Expert Insight: The Critical Role of VIN Programming
As a technician with over 20 years of experience, I’ve seen countless vehicle owners install a used, unprogrammed computer only to create more problems. Without VIN-specific programming, your vehicle’s anti-theft system (Passlock/VATS) will prevent the engine from starting. You can also experience incorrect transmission shift points or false sensor readings because the module isn’t calibrated for your exact options. Our process eliminates these headaches. By programming the module to your VIN, we ensure it’s a true plug-and-play part that communicates perfectly with every other system in your vehicle from the moment you install it.
Frequently Asked Questions
How do I provide my VIN number?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot program and ship your ECM until we receive this information.
Is any additional programming needed after installation?
No. This ECM comes fully programmed for your vehicle. In most cases, it is a simple plug-and-play installation. However, some vehicles may require a security relearn procedure, which is a simple process you can typically do yourself. Instructions can be provided upon request.
Will this fix my specific problem?
This ECM is a direct solution for issues caused by a failing computer, including internal processor faults (like DTC P0606). While it resolves the most common electronic engine problems, we always recommend having a qualified mechanic properly diagnose your vehicle to confirm the ECM is the point of failure before ordering.
Is this compatible with my 2009 Silverado 1500?
Yes, this ECM is compatible with a wide range of GM vehicles beyond the 2009-2010 Silverado 2500. Please review the detailed fitment list on this page to confirm it matches your specific make, model, and engine options. Using the correct part number (12625455 or 12629009) is the best way to ensure a perfect match.
Where is the VIN located on my vehicle?
You can typically find your 17-digit VIN on a metal plate on the driver’s side dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
