Is your Buick Century, or another compatible GM vehicle, suffering from erratic behavior, poor fuel economy, or a persistent check engine light? These are classic signs that the brain of your vehicle, the Powertrain Control Module (PCM), may be failing. This replacement PCM, part number 12209614, is the definitive solution to restore your vehicle’s performance, drivability, and reliability. We take the guesswork out of the repair by programming the module to your specific Vehicle Identification Number (VIN) before it ships, ensuring a seamless installation process.
Diagnosing a Faulty 2001-2002 Century PCM
The PCM is the central command center for your engine and transmission. When it begins to fail, it can cause a cascade of confusing and frustrating symptoms. A faulty module can misinterpret sensor data, send incorrect commands to fuel injectors or ignition coils, and cause poor transmission shifting. Replacing the module with a correctly programmed unit is often the only way to permanently resolve these deep-seated electronic issues.
From the Diagnostic Bay
We once had a 2002 Buick Century come in with what the owner was convinced was a failing transmission. It was shifting hard between first and second gear and occasionally felt like it was slipping. He had already spent a fair amount on a transmission fluid service with no improvement. After hooking up our diagnostic scanner, we noticed erratic torque converter clutch commands coming from the PCM. There were no specific transmission codes, just performance codes. We swapped in a VIN-programmed PCM, and the ‘transmission problem’ vanished instantly. It was a perfect example of how a faulty PCM can mimic a major mechanical failure, saving the customer thousands in unnecessary repairs.
Common Symptoms of a Failing PCM
- ✔ Persistent Check Engine Light (CEL) illumination
- ✔ Engine stalling, stumbling, or rough idling
- ✔ Noticeable decrease in fuel efficiency
- ✔ Harsh or erratic automatic transmission shifting
- ✔ Failure to pass emissions testing
- ✔ Intermittent starting problems or no-start conditions
- ✔ Communication errors with diagnostic scan tools

Frequently Asked Questions
Do I need to get this PCM programmed by a dealer?
No. We program the module to your vehicle’s VIN before we ship it to you. It will arrive ready to be installed, flashed with the latest software from GM for your specific vehicle.
What is a security relearn procedure?
After installation, some GM vehicles require a simple ‘security relearn’ to sync the new PCM with your vehicle’s anti-theft system. This can typically be done without any special tools and involves a sequence of key turns. Instructions are readily available online for your specific model.
How do I find my vehicle’s VIN?
Your 17-digit Vehicle Identification Number (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 part a guaranteed fix for my vehicle’s problems?
This PCM will fix any issues directly caused by a faulty module. However, it’s crucial to ensure your vehicle has been properly diagnosed. This part will not fix problems related to other failed components like sensors, wiring, or mechanical parts.
What part numbers does this module replace?
This module is a direct replacement for part numbers 12209614, 12202600, and 09360210. Matching one of these numbers is the best way to ensure compatibility.
