Restore Your Vehicle’s Core Performance
The Powertrain Control Module (PCM), often called the Electronic Control Module (ECM), is the central computer of your 2000-2002 Buick Regal and many other GM vehicles of the era. It’s responsible for managing a complex web of systems, including fuel injection, ignition timing, transmission shifting, and emissions controls. When the PCM begins to fail, it can cause a cascade of confusing and frustrating problems that can be difficult to diagnose. From a persistent check engine light to erratic engine behavior or even a complete no-start condition, a faulty PCM can bring your vehicle to a standstill. This replacement module is the definitive solution to restore your vehicle’s original functionality and reliability.
From the Diagnostic Bay
I once had a 2001 Pontiac Grand Am come into the shop with a classic case of what the owner thought was a bad transmission. It was shifting hard, hesitating, and occasionally throwing a random sensor code. They had already replaced two different transmission solenoids with no luck. After hooking up our professional scan tool and monitoring live data, we noticed the PCM wasn’t sending consistent signals to the transmission. The voltage was fluctuating erratically. We swapped in a correctly programmed PCM, performed the security relearn, and the car drove like it just left the factory. It’s a powerful reminder that what seems like a major mechanical failure can often be an electronic issue originating from a failing PCM.
Common Symptoms of a Failing PCM
- ✔ Check Engine Light: The most common indicator, often with codes related to multiple, unrelated sensors.
- ✔ Poor Engine Performance: Noticeable loss of power, hesitation during acceleration, or rough idling.
- ✔ Reduced Fuel Economy: The engine may run too rich or too lean, causing a significant drop in MPG.
- ✔ Intermittent Stalling: Your vehicle may stall unexpectedly while driving or when coming to a stop.
- ✔ No-Start Condition: The engine cranks but refuses to start, often due to a lack of fuel or spark command from the PCM.
- ✔ Harsh or Incorrect Shifting: The PCM controls transmission shift points, and failure can lead to erratic automatic shifting.
- ✔ Communication Errors: A diagnostic scan tool may be unable to communicate with the module, a clear sign of internal failure.
Your Direct Solution: A Programmed 2000-2002 Regal PCM
Navigating the repair of a failed computer can be daunting. Dealerships often charge a premium for the part and additional fees for programming. Our solution simplifies the entire process. This module, part number 09360210, is a direct-fit replacement for your original unit. The critical difference is our service: we program the module specifically for your vehicle using the VIN you provide at checkout. This ensures that it has the correct software and calibrations for your car’s specific engine, transmission, and options. It arrives ready for installation, loaded with the latest GM software updates to ensure optimal performance and longevity.
Simple Installation Process
Once you receive your pre-programmed module, the physical installation is straightforward. It is typically located in the engine compartment on the driver’s side. After disconnecting the battery, you simply unplug the electrical connectors from the old module, unbolt it, and install the new one in its place. The final step is a vital security relearn procedure, also known as a CASE relearn. This procedure syncs the new PCM with your vehicle’s anti-theft system and crankshaft position sensor. This is a non-negotiable step and can typically be performed without special tools in your driveway. Instructions are widely available online, or your local mechanic can perform it quickly.

Frequently Asked Questions
Do I need to do any programming myself?
No. We handle all the programming before shipment. We will flash the module with the latest GM updates using the VIN you provide. The only thing you’ll need to do after installation is the security relearn procedure.
What is a security relearn procedure?
It’s a simple process that syncs the new PCM to your vehicle’s anti-theft system. Without it, the vehicle will not start. It typically involves turning the key to the ‘ON’ position for 10-15 minutes, then ‘OFF’, and repeating this cycle three times. Specific instructions for your vehicle are readily available online.
Where is my VIN located?
Your 17-digit Vehicle Identification Number (VIN) can be found on your vehicle’s registration, insurance card, or on a small plate on the driver’s side of the dashboard, visible through the windshield.
Is this a guaranteed fix for my vehicle’s problems?
This module will fix any issues directly caused by a faulty PCM. However, it’s crucial to ensure your vehicle has been properly diagnosed. This part will not fix problems related to other faulty components like sensors, wiring, or mechanical parts.
What if I order the wrong part?
Please verify your original part number and check the compatibility list before ordering. Since each module is programmed to a specific VIN, it’s important to ensure you are purchasing the correct hardware for your vehicle. Contact us if you need help verifying fitment.
