Restore Your Truck’s Heartbeat
Is your 2002 Chevy Avalanche running rough, stalling, or refusing to start? A failing Powertrain Control Module (PCM) can bring your dependable truck to a dead stop, causing immense frustration and downtime. This isn’t just an inconvenience; it’s a critical failure that affects everything from fuel economy to shifting. Get back on the road with confidence with this direct-fit, professionally programmed 2002 Avalanche 1500 PCM 12200411, designed to restore the performance and reliability you depend on.
Common Symptoms & Your Solution
A faulty PCM can manifest in numerous ways, often mimicking other component failures. If you’re experiencing any of the following, your engine’s computer is the likely culprit:
- Check Engine Light: Persistent and often accompanied by codes like P0601 (Internal Memory Error) or P0606 (PCM Processor Fault).
- Erratic Engine Behavior: Unexplained stalling, rough idling, misfires, or poor acceleration.
- No-Start Condition: The engine cranks but won’t start, even with a good battery and fuel supply.
- Poor Fuel Economy: A sudden and significant drop in your truck’s MPG.
- Transmission Problems: Harsh or delayed shifting, as the PCM plays a crucial role in transmission control.
- Communication Errors: Your scan tool cannot communicate with the PCM.
This replacement module is the definitive solution. It arrives pre-programmed to your truck’s specific Vehicle Identification Number (VIN), loaded with the latest GM software updates. This process ensures all systems communicate correctly, eliminating the guesswork and the need for an expensive trip to the dealership for programming.
Expert Insight: The ‘Junkyard Gamble’ vs. A Programmed Solution
As a technician, I’ve seen countless vehicle owners try to save a few dollars by pulling a PCM from a salvage yard. This rarely ends well. An old PCM will have the VIN and options from the donor vehicle, which can trigger the anti-theft system (Passlock/VATS), cause incorrect transmission shifting, and disable features in your truck. Our process of programming this 2002 Avalanche 1500 PCM 12200411 to your specific VIN before it ships eliminates these headaches. It’s the difference between a frustrating weekend of troubleshooting and a simple, successful repair.

Frequently Asked Questions
Do I need to program this PCM?
No. We handle all the programming for you before we ship the part. We use your vehicle’s VIN to load the correct GM software and settings, making it ready for installation right out of the box.
Where is the PCM located on my 2002 Avalanche 1500?
On most GMT800 trucks like your Avalanche, the PCM is located in the engine bay on the driver’s side, typically under the battery tray or mounted to the inner fender.
What is a CASE Relearn and will I need to perform one?
A CASE (Crankshaft Angle Sensor Error) Relearn synchronizes the new PCM with your engine’s crankshaft position sensor. While our programming often prevents the need for it, in some cases, you may need a scan tool capable of performing this procedure to clear a P1336 trouble code after installation.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit VIN. We cannot program and ship your module without it. Instructions will be provided after checkout.
Will this fix my transmission shifting problems?
In many cases, yes. The PCM is responsible for controlling the transmission’s shift points and line pressure. If your shifting issues are caused by a faulty computer, this replacement part will resolve them. However, it will not fix internal mechanical issues with the transmission itself.
