Restore Your Acadia’s Reliability and Performance
A failing Engine Control Module (ECM) can turn your dependable GMC Acadia into a source of constant frustration, disrupting your family’s schedule and compromising safety. From a persistent check engine light to stalling and poor fuel economy, the symptoms of a bad ECM can be unsettling. This professionally programmed Engine Control Module is the definitive solution, designed to get your vehicle back on the road quickly and restore the smooth, reliable performance you depend on.

- Transmission shifting problems or communication errors
- Inability for diagnostic scan tools to communicate with the module

Expert Insight: Why VIN Programming is Non-Negotiable
As a technician with over two decades of experience, I can’t stress this enough: simply swapping an ECM from another vehicle won’t work on modern cars like your Acadia. The ECM is the ‘brain’ that communicates with the transmission, anti-lock brakes, security system, and more. Our VIN programming service isn’t just a convenience; it’s a necessity. It ‘introduces’ the new ECM to all other modules in your vehicle, ensuring they work together in harmony. Skipping this step leads to no-start conditions and a dashboard full of error lights, turning a simple repair into a complex nightmare. We handle this critical step for you, so you can be confident the job is done right.
Frequently Asked Questions
What do you need from me after I place my order?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit VIN (Vehicle Identification Number). We cannot program and ship your 2010-2011 GMC Acadia ECM without it.
Is this part difficult to install?
This ECM is designed for a direct, plug-and-play installation. The most critical part, the programming, is already done. While many experienced DIYers can perform the swap, we always recommend installation by a qualified mechanic to ensure everything is handled correctly, including disconnecting the battery beforehand.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the ECM (common codes include P0601, P0606), this part is the correct solution. However, if the light is on for another reason (e.g., a bad oxygen sensor), you will still need to address that separate issue.
Do I need to do anything after installation?
In most cases, no additional steps are required. Once installed, the vehicle should start and run correctly. Some vehicles may require a simple idle relearn or security relearn procedure, which can often be found in the owner’s manual or performed by your mechanic.
Is this the correct part for my vehicle?
This module fits the 2010-2011 GMC Acadia and several other GM models listed, including the Enclave, Traverse, and CTS with the 3.6L engine. Please verify that your original part number is one of the following: 19300015, 19300014, 12617230, 12636355, or 12635019 to ensure compatibility.
What if I have a Camaro or a LaCrosse?
For these specific models, the immobilizer (security) information must be transferred from your old ECM. If you purchase for a Camaro or LaCrosse, we will contact you with instructions for sending your original module to us to complete this process and make the new unit fully plug and play.
