Is Your 2010-2011 GM 3.6L Vehicle Running Poorly?
If your GMC Acadia, Buick Enclave, Chevy Traverse, or other compatible GM vehicle is experiencing frustrating issues like a persistent check engine light, rough idling, stalling, or a sudden drop in fuel economy, the root cause might be a failing Engine Control Module (ECM). The ECM is the central computer of your vehicle, responsible for managing everything from fuel injection and ignition timing to transmission shifting and emissions control. When it starts to fail, it can create a cascade of problems that are often misdiagnosed, leading to costly and unnecessary repairs of other components.
Don’t let a faulty computer keep you off the road. This replacement Engine Control Module, part number 12617230, is the definitive solution to restore your vehicle’s performance, reliability, and efficiency. We take the guesswork and hassle out of the replacement process by professionally programming the module to your vehicle’s specific Vehicle Identification Number (VIN) before it ever leaves our facility. This ensures a seamless installation and proper communication with all other onboard systems.
We recently had a 2011 Buick Enclave come into the shop with a complaint of intermittent stalling and a check engine light with codes for multiple sensor failures. The owner had already replaced the throttle body and a camshaft position sensor at another shop, but the problems persisted. Our diagnostics led us to test the ECM’s reference voltage outputs to the sensors, which were erratic. Instead of continuing to replace parts, we identified the failing ECM as the true culprit. After installing a VIN-programmed module like this one, all the phantom sensor codes vanished, and the vehicle ran perfectly. It’s a classic case of treating the disease, not just the symptoms.
Common Symptoms of a Failing ECM
- ✔ Persistent Check Engine Light (CEL) with various, often unrelated, trouble codes.
- ✔ Engine stalling or shutting off unexpectedly while driving.
- ✔ Rough or erratic idling and poor engine performance.
- ✔ Noticeable decrease in fuel mileage.
- ✔ Difficulty starting the engine or a complete no-start condition.
- ✔ Transmission shifting issues or harsh gear changes.
- ✔ Communication errors with diagnostic scan tools.
Why Choose Our Programmed 2010-2011 Acadia ECM?
Getting a replacement ECM from a dealership can be incredibly expensive, and buying a used one from a salvage yard is a gamble—it will not work without being properly programmed to your vehicle. Our solution provides the best of both worlds. We supply a fully functional module loaded with the latest GM-certified software, specifically calibrated to your car’s VIN. This process ensures that all factory settings, security information (immobilizer), and operational parameters are a perfect match for your vehicle’s configuration.
Simple Process:
- Place your order for the ECM.
- Provide us with your vehicle’s 17-digit VIN during or after checkout.
- Our technicians will program the module with the newest updates from GM.
- We ship the ready-to-install module directly to you.
For most compatible vehicles, installation is straightforward. Once installed, you may need to perform a simple security relearn procedure, which can typically be done without special tools. We provide clear instructions for this process. Please Note: For 2010-2011 Camaro and LaCrosse models, a special process is required to sync the immobilizer data. We will contact you after your purchase with instructions for sending us your original module to facilitate this data transfer, ensuring a true plug-and-play experience.

Frequently Asked Questions
Do I need to have this ECM programmed?
No. We handle all the programming for you before shipment. Simply provide your vehicle’s VIN at checkout, and the module will arrive ready for installation, loaded with the latest GM software for your specific vehicle.
What is a security relearn procedure?
A security relearn, or anti-theft relearn, syncs the new ECM with your vehicle’s existing anti-theft system. For most GM vehicles, this is a simple procedure that involves turning the key to the ‘ON’ position for 10-15 minutes, then ‘OFF’, and repeating two more times. We include instructions for this.
What is the special process for a Camaro or LaCrosse?
Due to the specific anti-theft system in the 2010-2011 Camaro and LaCrosse, we need to transfer immobilizer data from your original ECM to the new one. After your purchase, we will contact you with a prepaid shipping label and instructions to send your old module to us. This ensures the new ECM is 100% plug-and-play with no extra steps needed on your end.
Where is the ECM located on my vehicle?
The location varies slightly by model. On the Acadia, Traverse, Enclave, and Outlook, it’s typically located behind the fan shroud. On the LaCrosse and Allure, it’s in the LH engine compartment. For the CTS and STS, it’s found in the RH front engine compartment.
How do I find my VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on your vehicle’s registration, insurance card, or on a plate on the driver’s side dashboard visible through the windshield.
