Get Your Silverado Back to Work, Fast.
Is your reliable Chevy Silverado suddenly stalling, running rough, or refusing to start? A failing Engine Control Module (ECM) can bring your workhorse to a dead stop, costing you time, money, and peace of mind. This isn’t just an inconvenience; it’s a roadblock. We offer the definitive solution: a professionally programmed 2010-2013 Silverado 1500 ECM that arrives at your door ready for a straightforward installation. We take the guesswork and dealer-level costs out of the equation.
Common Symptoms & Your Direct-Fit Solution
A faulty ECM can manifest in frustrating ways. If your truck is experiencing any of the following, this module is the likely fix:

- Engine stalling unexpectedly while driving or at idle
- Noticeable decrease in fuel economy
- Rough idling or engine misfires
- Check Engine Light with communication error codes (like P0601, P0606)
- Transmission shifting issues or erratic behavior
Our solution is simple. We take a genuine, fully tested ECM and flash it with the latest official GM software, programmed specifically to your truckโs Vehicle Identification Number (VIN). This ensures perfect communication between all your vehicle’s systems, restoring the factory performance and reliability you depend on.

From the Shop Floor: We recently had a contractorโs 2011 Sierra 1500 in the bay. It would randomly stall at traffic lights, making it unreliable for getting to job sites. After chasing down potential fuel and spark issues with no luck, we identified the ECM as the culprit. Instead of a multi-day wait and a huge bill from the dealer, he ordered this exact pre-programmed 2010-2013 Silverado 1500 ECM. The installation took less than an hour in his own garage, and the truck has been running flawlessly ever since. That’s the difference between a problem and a solution.
Frequently Asked Questions
Do I need to program this ECM after I receive it?
No. The main benefit of our service is that we program the module for you before it ships. It will arrive ready to be installed, making the process as simple as possible.
What information do you need from me?
After you complete your purchase, you will need to provide us with your 17-digit Vehicle Identification Number (VIN). This is critical for us to load the correct software for your truck’s specific options and systems.
Where is the ECM located on my truck?
On the 2010-2013 Silverado and Sierra 1500, the ECM is located in the engine compartment on the driver’s side, typically under or near the battery tray. On Express and Savana vans, it is located in the left-hand rear of the engine compartment.
Will this fix my check engine light?
If your check engine light is caused by an internal failure of the ECM (common codes include P0601 through P0606), then yes, this part will resolve the issue. It’s always recommended to have your vehicle properly diagnosed to confirm the ECM is the point of failure.
My original part has a different service number. Will this still work?
Yes, as long as your original service number is one of the compatible numbers listed: 12635043, 12639471, or 12653246. This single 2010-2013 Silverado 1500 ECM is a direct replacement for all three.
What kind of warranty is included?
This unit is backed by our one-year replacement warranty, giving you confidence in your repair.
