Restore Peak Performance to Your Vehicle
Is your vehicle suffering from frustrating and unpredictable issues like stalling, poor fuel economy, or a persistent check engine light? These are classic signs of a failing Engine Control Module (ECM), the central computer that manages your engine’s performance. A faulty ECM can disrupt everything from fuel injection and ignition timing to transmission shifting, leaving you with an unreliable vehicle. This replacement Engine Control Module, part number 12629009, is the definitive solution to restore your vehicle’s original performance and reliability.
From the Diagnostic Bay
We had a 2009 Silverado 2500 come into the shop with a complaint of intermittent stalling and a check engine light that previous shops couldn’t solve. They had already replaced the throttle body and multiple sensors, costing the owner a small fortune. After hooking up our professional scan tool, we noticed erratic data coming from the ECM. The internal processors were failing under load. We installed one of these VIN-programmed modules, performed the security relearn, and the truck ran like it just rolled off the assembly line. It’s a common story: mechanics often chase symptoms, but sometimes the problem lies with the brain itself.
Is Your GM Vehicle Exhibiting These Symptoms?
A failing engine computer can manifest in numerous ways. If you’re experiencing any of the following, it’s highly likely your ECM is the culprit. This part is the direct solution for these common issues.
- ✔ Check Engine Light is on with various, often inconsistent, trouble codes.
- ✔ Engine stalling or shutting off unexpectedly while driving.
- ✔ Noticeable decrease in fuel efficiency for no apparent reason.
- ✔ Rough idling, misfires, or hesitation during acceleration.
- ✔ Difficulty starting the engine or a complete no-start condition.
- ✔ Automatic transmission shifting erratically or harshly.
- ✔ Communication errors with diagnostic scan tools.

Frequently Asked Questions
Do I need to get this module programmed?
No. This is the biggest benefit of our service. We program the module with the latest GM software using the VIN you provide during checkout. This makes the installation process much simpler, as it arrives ready to be installed in your vehicle.
What is a VIN and where do I find it?
The VIN is your vehicle’s unique 17-digit identification number. You can typically find it on a small plate on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Is any additional setup required after installation?
In most cases, a simple security relearn procedure (also known as a CASE relearn or anti-theft relearn) may be necessary. This procedure syncs the new ECM with your vehicle’s anti-theft system and can often be done without special tools. Instructions are widely available online for your specific model, or your mechanic can perform it in minutes.
How can I be certain this part will fit my vehicle?
The best way to ensure compatibility is to match the part number (12629009 or 12625455) from your original ECM. You can also review the extensive fitment list provided on this page. If you are still unsure, please contact us with your VIN, and we will be happy to verify the fitment for you.
What happens if I continue driving with a bad ECM?
Continuing to operate a vehicle with a failing ECM can lead to more severe problems. It can cause poor engine performance, damage to other components like the catalytic converter, leave you stranded with a no-start condition, and make the vehicle unsafe to drive due to stalling.
