Expert Insight from a 20-Year Veteran Technician
Before you replace your computer, always perform the simple checks first. A bad ground connection or a faulty ignition switch can mimic PCM failure. However, if you’ve confirmed your power and grounds are good and you’re still facing issues, a pre-programmed module is your best path forward. A junkyard unit won’t have your car’s specific VIN and security information, leading to a no-start situation and a trip to the dealer anyway. This 2002-2003 Buick Rendezvous PCM 12209614 is programmed to your vehicle, saving you that critical time, money, and frustration.

Frequently Asked Questions
How do I provide my vehicle’s 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 module until we receive this information, as the programming is specific to your car.
Will I need to do anything else after installing this PCM?
In many cases, this is a plug-and-play installation. However, some GM vehicles of this era may require a simple Security Relearn procedure, which can typically be done without special tools and involves a sequence of key turns. We include instructions for this common procedure.
Is this the correct part for my vehicle?
This module is compatible with a wide range of GM vehicles from the early 2000s. Please check the detailed fitment list on this page and ensure your original part number matches one of the compatible numbers (12209614, 12202600, 09360210). Providing your VIN ensures we program it perfectly for your exact make and model.
What if my car doesn’t start after installation?
A no-start condition is almost always related to the vehicle’s anti-theft system (Passlock/VATS). Performing the Security Relearn procedure will typically resolve this by allowing your vehicle’s security system to recognize the new PCM.
What makes your programming service different?
We use official GM-licensed software to flash your module with the newest, most stable calibration for your specific VIN. This ensures all systems, from the engine and transmission to the anti-lock brakes, communicate correctly for safe and efficient operation.
