Restore Peak Performance to Your 2002 Chevrolet Avalanche 1500

Is your 2002 Avalanche 1500 suffering from erratic engine behavior, poor fuel economy, or a persistent Check Engine Light? The Powertrain Control Module (PCM), the electronic brain of your vehicle, is often the root cause of these frustrating issues. This replacement PCM, compatible with part number 12200411, is the definitive solution to restore your truck’s reliability and drivability. It arrives at your door fully programmed to your vehicle’s specific Vehicle Identification Number (VIN), ensuring a straightforward installation process without the need for an expensive trip to the dealership.

The PCM is a critical component that manages everything from fuel injection and ignition timing to transmission shifting and emissions control. Over time, heat, vibration, and electrical surges can cause internal components to fail, leading to a host of performance problems. Replacing a faulty module with a generic, non-programmed unit can create even more issues. Our service eliminates that risk by flashing the module with the latest GM-certified software updates for your exact vehicle configuration. This ensures all systems communicate correctly, restoring the smooth operation and efficiency you expect from your Avalanche.

Common Symptoms of a Failing 2002 Avalanche PCM
n
- n
- ✔ Check Engine Light: The module may set various trouble codes (DTCs), often related to sensor circuits, communication errors (U-codes), or internal processor faults.
- ✔ Engine Stalling or Misfiring: The engine may stall unexpectedly, run rough, or hesitate during acceleration due to incorrect fuel and spark commands.
- ✔ No-Start Condition: A completely failed PCM can prevent the engine from starting by not activating the fuel pump or ignition system.
- ✔ Poor Fuel Economy: Inefficient engine operation caused by incorrect air/fuel mixture calculations will lead to a noticeable drop in MPG.
- ✔ Harsh or Erratic Shifting: The PCM controls the transmission, and a faulty module can cause delayed engagement, hard shifts, or getting stuck in one gear.
- ✔ Failure to Communicate: Your mechanic’s scan tool may be unable to connect with the PCM, making diagnosis impossible.

A Simple, Programmed Solution
n
Don’t let a faulty engine computer keep your truck off the road. This module is a direct-fit replacement for a wide range of GM trucks, vans, and SUVs from the 2001-2002 model years. The key to our service is the pre-programming. After your purchase, simply provide us with your VIN. Our technicians will use this information to load the correct factory software and updates onto the module. This makes the installation process as simple as disconnecting the battery, swapping the old module for the new one, and reconnecting the battery. In most cases, a simple security relearn procedure (often called a CASE learn) is all that’s needed to get you back on the road.

Frequently Asked Questions
What is a PCM?
The Powertrain Control Module (PCM) is your vehicle’s main computer. It controls all aspects of the engine and transmission to ensure optimal performance, fuel efficiency, and emissions.
Does this PCM come programmed?
Yes! This module is fully programmed to your vehicle’s VIN before it is shipped. You must provide your VIN after purchase. This ensures a plug-and-play installation without needing a trip to the dealer for programming.
What is a “CASE learn” or “crank relearn”?
A Crankshaft Position System Variation Learning (CASE learn) procedure may be required after installation. This allows the new PCM to learn the specific tolerances of your engine’s crankshaft position sensor for accurate misfire detection. This procedure can often be done without special tools or may require a scan tool with the appropriate function.
Where is the PCM located on my 2002 Avalanche 1500?
On the 2002 Avalanche 1500, the PCM is typically located in the engine bay on the driver’s side, under the battery tray. Always disconnect the battery before attempting to remove or install the module.
How do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your module without it.
Will this fix my specific problem?
While this PCM will resolve issues caused by a faulty module, 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.
