Restore Your Vehicle’s Core Performance and Reliability
If you’re dealing with a frustrating check engine light, erratic engine behavior, or poor fuel economy in your 2000-2002 Buick Regal, a failing Powertrain Control Module (PCM) is often the culprit. As the central computer for your engine, its proper function is critical. This isn’t just a replacement part; it’s a complete, reliable solution. We flash this module with the latest official GM software updates, specifically programmed to your vehicle’s VIN. This ensures seamless communication between all your vehicle’s systems and restores the performance and efficiency you expect.
Over my 20 years in automotive diagnostics, I’ve seen countless drivers replace expensive sensors and parts, only to find the root issue was the PCM all along. By providing a correctly programmed module, we eliminate the guesswork and the need for a costly trip to the dealership for programming. This is a direct-fit, plug-and-play solution designed to get you back on the road with confidence.
Common Signs of a Failing PCM
- ✔ Persistent Check Engine Light (CEL) with codes like P0601, P0602, or P0606.
- ✔ Unexplained stalling or engine hesitation, especially when warm.
- ✔ Noticeable decrease in fuel mileage.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Engine cranks but refuses to start (no-start condition).
- ✔ Failure to pass state emissions testing.
Case Study: A Tricky Diagnosis
A customer brought in a 2002 Pontiac Grand Am 3.4L with an intermittent no-start condition that had stumped two other shops. They had already replaced the crank sensor and fuel pump. When it did run, it would occasionally stall at stoplights. After hooking up my scan tool, I noticed communication with the PCM would drop out right before a stall. There were no clear trouble codes, just a history of random sensor faults. Based on experience with these GM platforms, I suspected an internal PCM failure. We installed a pre-programmed module just like this one, performed the security relearn, and the car fired up instantly. The customer reported back a month later that the car had been running perfectly ever since. It’s a classic example of how a faulty 2000-2002 Regal Powertrain Control Module can mimic other failures.
A Straightforward Guide to Installation
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery and secure it away from the post.
- ✔ Locate the Module: On most compatible vehicles like the Regal, the PCM is found in the engine bay, typically inside the air filter housing on the driver’s side (LH).
- ✔ Disconnect and Remove: Carefully unclip and disconnect the electrical wiring harnesses from the old module. Then, remove any bolts or clips holding the PCM in place and take it out.
- ✔ Install the New Module: Seat the new, pre-programmed PCM in the same location and secure it with the original hardware.
- ✔ Reconnect Everything: Firmly re-attach the wiring harnesses to the new module. You should hear a click as they lock in. Reconnect the negative battery terminal.
- ✔ Perform Security Relearn: This is a vital step. Turn the key to the ‘ON’ position (without starting) for 10-15 minutes. The security light should turn off. Turn the key off for 10 seconds, then repeat the process two more times. After the third cycle, the vehicle is ready to start. This syncs the new PCM with your vehicle’s anti-theft system.

Frequently Asked Questions
Frequently Asked Questions
Do I need to get this module programmed?
No. We handle the programming for you before shipping. Simply provide your vehicle’s 17-digit VIN during or after checkout, and we will flash the module with the latest GM software for your specific car.
Where do I find my VIN?
Your VIN can be found on a metal plate on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Is a ‘security relearn’ procedure difficult to do?
Not at all. It’s a simple procedure that anyone can do with just the vehicle’s key. It takes about 30 minutes and does not require any special tools. We include instructions to guide you through it.
Will this fix my transmission shifting problems?
The PCM also controls transmission functions, including shift points and line pressure. If your shifting issues are caused by a faulty module, this part will resolve them.
What part numbers does this module replace?
This module is a direct replacement for part numbers 12209614, 12202600, and 09360210. If your original module has one of these numbers, this part is compatible.
