End Engine Frustration and Restore Your Vehicle’s Performance
Is a persistent check engine light, poor fuel economy, or unpredictable stalling turning every drive into a stressful event? A failing Engine Control Module (ECM) is often the hidden culprit behind these frustrating issues, acting as the brain of your engine. This isn’t just an inconvenience; it affects your vehicle’s reliability, safety, and performance. We offer the definitive solution: a professionally programmed ECM, matched specifically to your vehicle’s VIN, ready to restore factory performance and get you back on the road with confidence.
Common Symptoms & Your Solution
If you’re experiencing any of the following, a faulty ECM is the likely cause:
- Persistent Check Engine Light (CEL) with codes like P0601, P0606, or U0100
- Unexplained drop in fuel mileage
- Engine stalling, stumbling, or hesitating during acceleration
- Rough or inconsistent idling
- Harsh or erratic automatic transmission shifting
- Intermittent no-start or hard-starting conditions
- Communication errors with diagnostic scan tools
Our Programmed 12635019 ECM is the direct answer to these problems. We take a quality-verified module and flash it with the very latest, most stable software release from General Motors, using your vehicle’s unique VIN. This ensures perfect compatibility and function, eliminating the guesswork and the high costs associated with a dealership visit.

An Expert’s Insight: Why VIN Programming is Non-Negotiable
As a technician with over two decades of experience, I’ve seen countless drivers try to save a few dollars by installing a used, non-programmed ECM from a salvage yard. It almost never ends well. Modern vehicles are complex networks, and the ECM is the central hub. Without the correct VIN, security keys, and option content (like transmission type or emissions equipment), the module simply won’t work. You’ll face a no-start condition, persistent error codes, or even damage to other electronics. Our service eliminates that risk entirely. By providing a Programmed 12635019 ECM, we’re not just selling a part; we’re delivering a proven, reliable repair that works the first time.
Frequently Asked Questions
What information do you need from me?
After you place your order, we require your 17-digit Vehicle Identification Number (VIN). This is essential for us to load the correct GM-certified software and settings for your specific vehicle configuration.
Do I need to have a mechanic install this?
While installation is straightforward for those with mechanical experience, we always recommend professional installation. After the new ECM is installed, a security relearn procedure (often called a key relearn or anti-theft relearn) is typically required. This procedure can usually be performed by the owner and does not require a scan tool. We can provide instructions upon request.
What is the special process for Camaro and LaCrosse models?
For the 2010-2011 Camaro and LaCrosse, the immobilizer (anti-theft) information is stored uniquely within the ECM. To ensure a true plug-and-play experience, you will need to send us your original module. We will expertly transfer this critical data to your new Programmed 12635019 ECM. We will contact you with shipping instructions after your purchase.
How do I find my part number to confirm compatibility?
Your original ECM will have a sticker with the part number on it. This unit is a direct replacement for part numbers 19300015, 19300014, 12617230, 12636355, and 12635019. However, our VIN programming ensures compatibility even if your number differs slightly, as long as your vehicle is listed.
Is this a brand new part from the dealer?
This is a quality-tested, verified component that has been meticulously inspected and prepared to meet or exceed original equipment standards. It is then loaded with the latest vehicle-specific software from GM, providing a reliable and effective solution.
