Restore Your Vehicle’s Performance and Reliability
Is your truck or SUV suffering from frustrating issues like stalling, poor acceleration, a persistent check engine light, or a no-start condition? A failing Engine Control Module (ECM) is often the culprit, acting like a broken brain for your vehicle. This isn’t just an inconvenienceโit’s a critical failure that can leave you stranded. Get back on the road with confidence with this direct-fit, professionally programmed ECM, designed to restore your vehicle’s factory performance and dependability.
Common Symptoms of a Failing ECM & Your Direct Solution
If you’re experiencing any of the following, it’s a strong indicator that your engine computer has failed. This unit is the definitive solution for these complex electrical issues:
- Check Engine Light (CEL) with communication-related Diagnostic Trouble Codes (DTCs) like P0601, P0602, P0606, or U0100.
- Engine Stalling or Misfiring: Unpredictable engine behavior, rough idling, or sudden shutdowns.
- No-Start Condition: The engine cranks but refuses to start, often due to a lack of fuel injector or ignition coil signals from the ECM.
- Poor Fuel Economy & Performance: A noticeable drop in MPG and sluggish acceleration as the ECM fails to manage the engine correctly.
- Communication Loss: Your diagnostic scan tool is unable to communicate with the engine computer.
This isn’t a generic, off-the-shelf part. We take your vehicle’s unique Vehicle Identification Number (VIN) and flash this module with the latest, most stable software updates directly from GM.

An Expert’s Note on VIN Programming
As a technician with over 20 years of experience, I can’t stress this enough: VIN programming is not optional. On modern GM vehicles, the ECM is tied directly to the anti-theft system (VATS/Passlock) and other critical modules. Simply installing a blank or used computer from another vehicle will result in a no-start condition. Our VIN flashing service writes your vehicle’s specific information to the module before it ships, saving you hundreds of dollars and the massive headache of towing your vehicle to a dealer. This is the correct way to do the job right the first time.
Don’t let a faulty computer keep your vehicle down. This is the most reliable and straightforward way to fix complex electronic issues and get your truck or SUV running perfectly again. By ordering our Programmed 2010-2013 Silverado 1500 ECM 12633055, you’re not just buying a part; you’re buying a complete, ready-to-install solution that brings your vehicle back to life.
Frequently Asked Questions
Do I need to do any additional programming after I receive the ECM?
No, this ECM comes fully programmed to your vehicle’s VIN with the latest GM software. In some vehicles, a simple, key-on/key-off security relearn procedure may be required, which takes about 30 minutes and does not require any special tools. We include instructions for this procedure.
Where do I provide my vehicle’s VIN?
After you complete your purchase, you can add your VIN to the ‘notes’ section of your order. If you forget, we will contact you via email to request it before we program and ship your module. We cannot ship the part without your VIN.
Is this a brand new part from the dealer?
This is a high-quality, fully tested, and inspected component that has been professionally prepared for your vehicle. It is programmed to meet or exceed original factory specifications and provides a reliable, cost-effective solution.
How can I be sure my old ECM is the problem?
While the symptoms listed above are classic signs of ECM failure, we always recommend a proper diagnosis by a qualified mechanic. Common trouble codes like P0601 (Internal Control Module Memory Check Sum Error) are a very strong indication that the ECM itself is the source of the problem.
Will this fit vehicles other than the Silverado?
Yes. This ECM, part number 12633055, fits a very wide range of GM trucks, vans, SUVs, and performance cars from roughly 2010-2017. Please check the detailed fitment list on this page or contact us with your VIN to confirm compatibility for your specific vehicle.
What does the one-year replacement warranty cover?
Our warranty covers the ECM unit itself. If the module fails due to an internal defect within one year from the date of purchase, we will provide a replacement unit. The warranty does not cover issues caused by external vehicle faults, such as wiring shorts or improper installation.
