Is Your Acadia Running Rough? Get Back on the Road with Confidence.
There’s nothing more frustrating than a vehicle you can’t rely on. If your 2009 GMC Acadia, Enclave, Traverse, or other compatible GM vehicle is suffering from a persistent check engine light, stalling unexpectedly, or just doesn’t have the power it used to, a failing Engine Control Module (ECM) is often the culprit. This isn’t just an inconvenience; it’s a core problem that affects performance, fuel economy, and your peace of mind. We offer the definitive solution: a genuine GM engine computer, professionally programmed to your vehicle’s specific VIN, ready for a straightforward installation.

Expert Insight: The ‘Ghost’ in the Machine
We once worked with a customer who owned a 2009 Buick Enclave. For months, he chased a random stalling problem that no one could diagnose. He replaced the crankshaft sensor, camshaft sensors, and even the fuel pump, but the stalling persisted. The issue was intermittent and left no clear codes. Finally, after suspecting the computer itself, he ordered a programmed 2009 Acadia ECM from us. The installation took him under an hour in his driveway. The result? The stalling completely vanished. His vehicle has run perfectly ever since. This is a classic example of how a failing ECM can mimic other part failures, making it the true ‘ghost’ in the machine.
Take the guesswork out of your repair. By providing us with your VIN upon purchase, you ensure that the programmed 2009 Acadia ECM you receive is the perfect match for your vehicle’s specific systems and options, making the installation process as seamless as possible.
Frequently Asked Questions
Do I need to do any programming myself?
Absolutely not. This ECM comes fully programmed to your vehicle’s VIN with the latest GM software. It is ready to be installed right out of the box. In some cases, a simple ‘security relearn’ procedure may be required after installation, which you can easily do yourself in about 10-15 minutes.
Where do I find my vehicle’s VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found in several places: on a metal plate on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, and on your vehicle’s registration and insurance documents.
What is the security relearn procedure?
The security relearn procedure helps the new ECM recognize your vehicle’s anti-theft system. It typically involves turning the key to the ‘ON’ position for 10 minutes, then ‘OFF’ for 10 seconds, and repeating this cycle three times. We can provide simple instructions for this common procedure.
Will this fix my specific check engine light?
This module is a direct solution for a failed ECM, which is the cause of many trouble codes, especially internal processor codes like P0601 or P0606. While it resolves a wide array of issues, we always recommend that the vehicle is properly diagnosed by a professional to confirm the ECM is the point of failure.
Is this part difficult to install?
For someone with basic mechanical skills, this is a very manageable job. The ECM is typically located behind the fan shroud in the engine bay. The process involves disconnecting the battery, unplugging the electrical connectors from the old ECM, unbolting it, and then installing the new one in the reverse order. No special tools are usually required.
My original part number isn’t 19300016, will this still work?
Yes. This ECM is a direct replacement for several part numbers, including 12623325, 12628387, 12605672, and 12630594. As long as your vehicle is listed in the compatibility chart, this module will function correctly once programmed to your VIN.
