When it falters, your vehicle’s reliability and performance suffer dramatically. This replacement PCM, part number 12200411, is the definitive solution to get your truck or van running like new again.

Before replacing your PCM, always verify that your battery is fully charged and that all battery cable connections and primary engine grounds are clean and tight. A weak battery or a poor ground connection can mimic PCM failure symptoms, leading to a misdiagnosis. A quick check can save you time and money.
Common Symptoms of a Failing PCM
- ✔ Persistent Check Engine Light (CEL) with various trouble codes.
- ✔ Engine stalling, stumbling, or misfiring.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ A noticeable decrease in fuel economy.
- ✔ The engine cranks but refuses to start.
- ✔ Failure to pass state emissions tests.
- ✔ Communication errors with diagnostic scan tools.
The Programming Process: Tailored for Your Vehicle
The key to a successful PCM replacement is proper programming. The 2001-2002 Chevy 3500 PCM and its equivalents require specific calibration files based on your truck’s engine, transmission, axle ratio, and other factory options. By using your VIN, we ensure the unit you receive has the exact software it needs. This eliminates the need for an expensive trip to the dealership for programming. Once installed, you may need to perform a simple security relearn procedure (often called a CASE relearn), which can typically be done in your driveway with just the ignition key. This syncs the new PCM with your vehicle’s anti-theft system.
This module is a direct replacement for multiple part numbers, including 12200411, 12201281, 12576160, and 52369718, and fits a wide range of popular GM models such as the Chevrolet Silverado, Tahoe, Suburban, Express Van, and GMC Sierra, Yukon, and Savana.
