Is your 2010-2011 GMC Acadia or other compatible GM vehicle suffering from frustrating and unpredictable engine problems? Issues like stalling, a persistent Check Engine Light, poor fuel economy, or a complete no-start condition often point directly to a failing Engine Control Module (ECM). As the central computer of your vehicle, a faulty ECM can disrupt everything from fuel delivery to transmission shifting, making your vehicle unreliable. Don’t let a bad module keep you off the road or lead to an expensive dealership visit.
This is your direct-fit, reliable solution. We provide a high-quality replacement ECM that is professionally programmed to your vehicle’s specific Vehicle Identification Number (VIN). This critical step ensures complete compatibility and functionality right out of the box. We flash the module with the latest, most stable software updates from GM, which can resolve factory bugs and improve overall performance and efficiency. Simply provide your VIN after purchase, and we’ll handle all the programming before it ships. This means for most vehicles, installation is a straightforward swap with no further programming required.
Common Signs of a Failing ECM
- âś” Check Engine Light is on with various trouble codes, especially communication (U-codes) or internal processor errors (e.g., P0601, P0606).
- âś” The engine cranks but refuses to start.
- âś” Unexplained stalling or rough idling.
- âś” Noticeable decrease in fuel efficiency.
- âś” The vehicle enters a reduced power or “limp” mode.
- âś” Automatic transmission shifts erratically or harshly.
- âś” Intermittent issues that are difficult to diagnose and seem to have no other cause.
A Technician’s Notebook
I recently had a 2011 Buick Enclave (which shares the same platform and ECM as the Acadia) in my bay with a classic case of ECM failure. The customer reported intermittent stalling at stoplights and a P0606 code (ECM/PCM Processor Fault) that would come and go. After verifying the power and ground circuits to the ECM were solid, we knew the internal processor was the culprit. Instead of a lengthy and costly diagnostic process at the dealer, we installed one of these pre-programmed modules. The entire job took less than an hour, permanently resolving the stalling and clearing the code. The customer was back on the road the same day, having saved significant time and money.
This 2010-2011 Acadia ECM is the dependable heart of your vehicle’s engine management system. By ordering a pre-programmed unit, you are not just buying a part; you are getting a comprehensive solution that restores function and peace of mind.
A Straightforward Guide to Installation
- âś” Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait at least 10 minutes to allow the system to fully discharge before beginning work.
- âś” Locate the ECM: On the 2010-2011 Acadia, Traverse, and Enclave, the ECM is typically located behind the engine’s cooling fan shroud. You may need to remove the air intake ducting for better access. On other models like the CTS or STS, it’s often in the engine compartment on the passenger (RH) or driver (LH) side.
- âś” Disconnect the Old Module: Carefully release the locking tabs on the electrical connectors and pull them straight out. Avoid wiggling them side-to-side to prevent pin damage. Once disconnected, unbolt the module from its mounting bracket.
- âś” Install the New Module: Bolt the new, pre-programmed ECM into place. Firmly reconnect the electrical harnesses, ensuring the locking tabs click securely into position.
- âś” Final Steps: Reconnect the negative battery terminal. In some cases, a Crankshaft Position System Variation (CASE) relearn procedure may be required, which can be performed with many professional-grade scan tools. Start the vehicle and check for proper operation and ensure the Check Engine Light is off.
Important Note for Camaro & LaCrosse Owners: Due to the specific anti-theft (immobilizer) systems in the 2010-2011 Camaro and LaCrosse, making this part truly plug-and-play requires us to transfer data from your original ECM. If you purchase this module for one of these two vehicles, we will contact you with instructions for sending your old unit to us for this service.

Frequently Asked Questions
What does ‘VIN Programmed’ mean?
It means we load your vehicle’s unique 17-digit Vehicle Identification Number (VIN) and the latest GM-certified software onto the ECM before we ship it. This ensures the module communicates correctly with all other systems in your specific vehicle, just like one from the dealership.
Do I need to do any programming after I install it?
For most vehicles listed, no further programming is needed. It arrives ready for installation. For some vehicles, a simple, non-programming procedure like a CASE relearn might be beneficial, which can be done with a common scan tool.
How do I provide my VIN?
After you complete your purchase, simply send us a message with your 17-digit VIN. You can find it on your vehicle’s dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle registration and insurance documents.
Why do you need my old ECM for a Camaro or LaCrosse?
The Camaro and LaCrosse have a more integrated immobilizer (anti-theft) system. To ensure your keys work and the car starts without a trip to the dealer for key programming, we need to extract specific security data from your old module and transfer it to the new one. We will provide instructions for this process.
Will this fix my specific problem?
This 2010-2011 Acadia ECM is a common solution for a wide range of drivability problems, especially those related to internal processor failure codes (like P0606) or communication errors. While we cannot diagnose your vehicle remotely, a faulty ECM is a very likely cause for the symptoms listed.
What if my original part number is slightly different?
This module is a direct replacement for several part numbers, including 19300015, 19300014, 12617230, 12636355, and 12635019. If your part number is on this list, this module is the correct fit for your vehicle.
