Get Your Family’s Buick Enclave Running Reliably Again
Is your 2009 Buick Enclave suffering from frustrating and unpredictable issues? A check engine light that won’t go away, sudden stalling, rough idling, or even a complete failure to start can turn your family’s trusted SUV into a source of daily stress. These are classic signs of a failing Engine Control Module (ECM), the critical computer that manages your vehicle’s performance and efficiency. Instead of facing a costly and time-consuming trip to the dealership, get the definitive, hassle-free solution that restores your vehicle’s performance and your peace of mind.
Common Symptoms & Your Direct Solution
A failing ECM can manifest in numerous ways, often mimicking other component failures. If you’re experiencing any of the following, a faulty engine computer is the likely culprit:
- Persistent Check Engine Light (CEL) with codes like P0601, P0606, or other internal processor faults.
- Unexplained stalling or engine hesitation, especially when warm.
- Rough or erratic idling.
- A no-start condition where the engine cranks but won’t turn over.
- Poor fuel economy and decreased engine power.
- Communication errors with diagnostic scan tools.
This module is your direct-fit, plug-and-play solution. We take the guesswork out of the repair by pre-programming this unit specifically to your vehicle’s unique VIN. This ensures that when it arrives, it’s ready for installation, integrating seamlessly with your Enclave’s existing systems.

An Expert’s Insight: Why Fresh Programming is Crucial
“Many drivers consider a used ECM from a salvage yard to save money, but this is a huge gamble. A used module not only carries the original vehicle’s VIN and specific options, making it incompatible, but it may also have the same underlying flaws that caused it to fail in the first place. Our process ensures you receive a reliable module loaded with the newest GM-certified software for your specific VIN. This fresh programming corrects factory bugs and optimizes performance in a way that even a dealer might overlook on an older vehicle. It’s the key to a lasting, trouble-free repair.”
Don’t let a faulty computer keep your family’s vehicle sidelined. By ordering this programmed 2009 Buick Enclave ECM, you’re not just buying a part; you’re investing in reliability, safety, and the confidence to hit the road without worry. It’s the smart, effective repair your vehicle deserves.
Frequently Asked Questions
What do I need to do after I purchase?
After you complete your purchase, you must provide us with your vehicle’s 17-digit VIN (Vehicle Identification Number). We cannot ship your order until we receive this information, as we use it to program the module specifically for your car.
Is this module difficult to install?
The physical installation is typically straightforward for anyone with basic mechanical skills, as the ECM is usually in an accessible location (behind the fan shroud on the Enclave). While it’s pre-programmed, you may need to perform a simple security relearn procedure (often called a ‘key relearn’ or ‘anti-theft relearn’), which can usually be done without special tools. Instructions are widely available online for this process.
How do I find my vehicle’s VIN?
Your VIN can be found on a metal tag 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.
My original ECM has a different part number. Will this still work?
Yes. This module is a compatible replacement for several part numbers, including 12623325, 12628387, 12605672, 12630594, and 19300016. As long as your original part number is on this list and your vehicle model is listed in the compatibility chart, this unit will work perfectly once programmed to your VIN.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the original ECM (e.g., DTC P0601), this replacement will solve the problem. However, if the light is on due to a separate issue like a bad sensor or wiring problem, you will still need to diagnose and repair that underlying fault. This programmed 2009 Buick Enclave ECM provides a solid foundation for a healthy engine management system.
