If you’re dealing with a persistent check engine light, erratic engine behavior, or frustrating transmission issues in your 2002 Chevy Avalanche, a failing Powertrain Control Module (PCM) is often the culprit. This isn’t just an inconvenience; it affects your truck’s reliability, fuel economy, and overall performance. This replacement PCM is the definitive, hassle-free solution to restore your vehicle’s brainpower and get you back on the road with confidence.

Common Symptoms & Your Direct-Fit Solution
A faulty PCM can cause a wide range of confusing problems. If your truck is experiencing any of the following, it’s time for a replacement:
- Check Engine Light: Especially for codes like P0601 (Internal Control Module Memory Check Sum Error), P0602, P0604, or P0606.
- Poor Performance: Noticeable loss of power, hesitation during acceleration, or a significant drop in fuel mileage.
- Erratic Shifting: Harsh or delayed gear changes from your automatic transmission.
- Engine Stalling or Rough Idle: The engine may stall unexpectedly or run unevenly at a stop.
- No-Start Condition: The engine cranks but refuses to start, even with a good battery and starter.
This module is the direct solution to these issues. By ordering our pre-programmed 2002 Avalanche 1500 PCM 12200411, you are bypassing a costly trip to the dealership and eliminating the guesswork from your repair.

A Mechanic’s Insight:
“I had a customer with a 2002 Sierra, which uses the same PCM, that had a stubborn P0601 code. The truck would randomly stall at red lights. He’d already replaced sensors trying to chase the problem. We identified the internal PCM fault, and installing a VIN-programmed unit like this one was the only correct fix. The new module cleared the code permanently and the truck ran perfectly. Don’t waste time and money on other parts until you’ve ruled out the vehicle’s main computer.”

Frequently Asked Questions
Do I need to do anything after I install this PCM?
Yes. You will need to perform a simple security relearn procedure, also known as a CASE relearn. This process syncs the new PCM with your vehicle’s anti-theft system and crankshaft position sensor. We provide clear, easy-to-follow instructions to complete this yourself in about 15-20 minutes without any special tools.
Where do I provide my vehicle’s VIN?
After you complete your purchase, you will receive instructions on how to send us your 17-digit VIN. We cannot program and ship your module until we receive this information, so please provide it promptly to avoid delays.
How do I know if my original PCM is actually bad?
While the symptoms listed above are strong indicators, the most definitive sign is a diagnostic trouble code specifically pointing to an internal module failure, such as P0601 through P0606. If you are experiencing multiple, unrelated error codes, it can also point to a failing PCM.
Will this fix my transmission shifting problems?
In many cases, yes. The PCM controls the transmission’s shift points and line pressure. If your shifting issues are electronic in nature (not caused by a mechanical failure inside the transmission), this programmed 2002 Avalanche 1500 PCM 12200411 is designed to correct them.
What’s the difference between a PCM, ECM, and ECU?
The terms are often used interchangeably. PCM (Powertrain Control Module) is the most accurate for this GM application, as it controls both the engine and transmission. ECM (Engine Control Module) and ECU (Electronic Control Unit) are more generic terms for a vehicle’s computer.
