An Expert’s Note on GM Programming
As a technician with over two decades of experience, I’ve seen firsthand how critical correct programming is on these early 2000s GM vehicles. The PCM doesn’t just manage the engine; it communicates constantly with the transmission controller, the anti-lock brake system, and even the instrument cluster. An improperly programmed module can cause a cascade of issues that seem unrelated, from hard shifting to inaccurate speedometer readings. That’s why our VIN-specific flashing process is so important. We ensure all the handshake protocols and software calibrations match your exact vehicle, providing a seamless integration that a generic, non-programmed part simply can’t offer. This is the key to a lasting and effective repair for your 2001-2002 Buick Century PCM.
Frequently Asked Questions
Do I need to do any programming myself?
No. This module arrives 100% pre-programmed to the VIN you provide during checkout. The installation is plug-and-play, with no additional programming or dealer visit required.
What happens after I place my order?
After you purchase the PCM, you must provide us with your vehicle’s 17-digit VIN. We cannot ship the part until we have this information. Once we receive your VIN, we will program the module and ship it to you.
Where can I find my vehicle’s VIN?
Your VIN can be found on your vehicle’s registration, insurance card, or on a metal plate on the driver’s side of the dashboard, visible through the windshield.
Is this a difficult part to install?
For most of the compatible vehicles, the PCM is located in the engine compartment and is relatively easy to access. Installation typically involves disconnecting the battery, unplugging the electrical connectors, unbolting the old module, and then reversing the process. Basic hand tools are usually all that is required.
How do I know for sure that my PCM is the problem?
While the symptoms listed above are strong indicators, a definitive diagnosis from a qualified mechanic is always the best course of action. Common diagnostic codes pointing to PCM failure include P0601, P0605, and P0606.
