An Expert’s Note on VIN Programming: A PCM isn’t just a generic part; it’s a computer tailored to your car’s specific options—from the engine and transmission to the type of radio it has. When we program this module to your VIN, we are digitally building it to match your car’s original factory specifications. This is the critical step that separates a successful, hassle-free repair from a frustrating one. Generic, non-programmed modules can’t communicate properly, leading to more error codes and a car that still won’t run right. We handle this essential process for you, ensuring the part you receive works exactly as it should.

Frequently Asked Questions
Do I need to do any programming myself?
No. We handle all the programming before the PCM is shipped to you. It will arrive ready to be installed. You may need to perform a simple key/security relearn procedure, which can be done without any special tools and typically takes 10-15 minutes. Instructions are readily available online for your specific model.
Where do I provide my VIN?
After you complete your purchase, you will need to send us your vehicle’s 17-digit VIN. You can typically add this as a note during checkout or send it to us in a message referencing your order number. We cannot ship your part until we have this information.
Is this compatible with other part numbers?
Yes, this PCM is a direct replacement for several part numbers, including 12616866, 12619810, and 12509307. If your original module has any of these numbers, this unit will work perfectly for your vehicle.
Where is this module located on my vehicle?
For the Pontiac Grand Prix, Buick LaCrosse, Allure, and Lucerne models covered, the Electronic Control Module (PCM) is located in the lower part of the air cleaner box/housing in the engine bay. It’s an accessible location for a straightforward replacement.
How can I be sure my old PCM is the problem?
While the symptoms listed above are strong indicators of a failing PCM, proper vehicle diagnostics are always recommended. This includes checking all power and ground connections to the module and ruling out sensor or wiring issues. However, if you are experiencing multiple, seemingly unrelated electronic issues or have specific PCM internal fault codes, the module itself is the most probable cause.
