An Expert’s Note on Diagnostics

This pre-programmed 2008-2009 Buick Allure ECM doesn’t just replace a part; it provides a definitive solution to complex electronic issues, saving you time, money, and frustration.”
Frequently Asked Questions
Do I need to get this programmed?
No. The main benefit of our service is that we program the module for you before it ships. Simply provide us with your vehicle’s VIN during or after checkout, and it will arrive ready for a plug-and-play installation.
How do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information, as it is essential for the programming process.
Is this a difficult part to install?
For many GM vehicles, including the Buick Allure, the ECM is located in an accessible area (often in the lower air cleaner housing). Installation typically involves disconnecting the battery, unplugging the electrical connectors, and unbolting the old module to swap in the new one. While many customers with basic mechanical skills can perform the installation, we always recommend consulting a service manual or a professional technician if you are unsure.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the original ECM (such as with code P0601), this replacement part is the correct fix. After installation, the code will need to be cleared with a standard OBD2 scan tool.
What service numbers does this part replace?
This ECM is a direct replacement for multiple service numbers, including 12590032, 12602044, 12603530, 12605843, 12607096, 12630457, and 19210737, among others listed in the full fitment guide.
