Is Your GM Vehicle Stalling, Running Rough, or Showing a Check Engine Light?
If you’re experiencing frustrating and unpredictable engine problems with your 2010-2011 GMC Acadia, Buick Enclave, Chevy Traverse, or other compatible GM model, a failing Engine Control Module (ECM) is a very likely culprit. 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 begins to fail, it can create a cascade of issues that are difficult to diagnose and can leave you stranded. This direct-replacement ECM, part number 12617230, is the definitive solution to restore your vehicle’s performance, reliability, and drivability.
From the Diagnostic Bay
We recently had a 2011 Buick Enclave come into the shop with a complaint of intermittent stalling at stoplights and a persistent P0606 (ECM/PCM Processor Fault) trouble code. The owner had already spent a significant amount of money replacing the throttle body and multiple sensors based on another shop’s advice, but the problem persisted. After confirming stable power and ground to the module, our diagnostics pointed directly to an internal failure of the ECM. We installed one of our VIN-programmed modules, performed the necessary security relearn procedure, and the vehicle ran perfectly. This is a classic case where chasing symptoms instead of addressing the root cause—the failing computer—leads to wasted time and money. A faulty ECM can send false signals, making other good components appear to be the problem.
Common Symptoms of a Failing ECM
A failing engine computer can manifest in numerous ways. If you’re noticing any of the following symptoms, it’s a strong indication that your ECM needs attention:
- ✔ Persistent Check Engine Light (CEL) that won’t clear, or codes related to processor faults (e.g., P0601-P0606).
- ✔ Unexplained engine stalling, hesitation, or stumbling, especially when warm.
- ✔ Rough idling or misfires that aren’t resolved by new spark plugs or ignition coils.
- ✔ Noticeable decrease in fuel economy.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Complete no-start condition where the engine cranks but will not fire up.
- ✔ Communication errors with diagnostic scan tools.
The Solution: A VIN-Programmed 2010-2011 Acadia ECM
Don’t let a faulty computer dictate your vehicle’s reliability. This replacement Engine Control Module is your path to a lasting repair. We take the guesswork and complexity out of the process. When you order, simply provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). Our technicians will then program the module with the latest, most stable software updates directly from GM, ensuring it is perfectly matched to your vehicle’s specific configuration and options. This critical step ensures that once you receive the part, it’s ready for a straightforward installation, saving you a costly trip to the dealership for programming.
This module is a direct replacement for a wide range of popular GM vehicles equipped with the 3.6L V6 engine. It is physically and electronically identical to the original unit, guaranteeing a perfect fit and seamless integration with your vehicle’s existing systems. It is compatible with multiple original equipment part numbers, including 19300015, 19300014, 12617230, 12636355, and 12635019.

Important Note for Camaro & LaCrosse Owners: Due to the specific anti-theft (immobilizer) systems in the 2010-2011 Camaro and LaCrosse, a fully plug-and-play installation requires us to transfer security data from your original ECM. After your purchase, we will provide instructions for you to send us your old module. We will clone the necessary information to the new unit, making it truly ready to install without any further procedures. This extra step ensures a hassle-free experience for these specific models.
Frequently Asked Questions
Do I need to have this ECM programmed by a dealer?
No. We handle all the programming for you before shipment. Simply provide your vehicle’s VIN during checkout, and the module will arrive loaded with the correct software for your specific vehicle, ready for installation.
Where do I find my vehicle’s VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found 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.
What is the extra step for a Camaro or LaCrosse?
For these two models, we need to transfer the unique immobilizer data from your old ECM to the new one. After you place your order, we will contact you with a prepaid shipping label and instructions to send your original module to us. This ensures the new ECM will communicate with your keys and security system correctly.
Is this a plug-and-play part?
For most listed models, yes. After our VIN programming, you can install it, and your vehicle will start and run. A standard security relearn procedure (often involving cycling the key) may be required, which can be done without special tools. For Camaro and LaCrosse, it becomes plug-and-play after we transfer data from your old unit.
Will this fix my specific problem?
This ECM is a direct solution for issues caused by a faulty engine computer, such as the symptoms listed above. While it solves a very common point of failure on these vehicles, we always recommend a proper diagnosis by a qualified mechanic to confirm the ECM is the root cause of your issue before ordering.
