Is Your GM Truck or Van Experiencing Critical Failures?
If your 2001-2002 Chevrolet Suburban 2500, Silverado, or other compatible GM vehicle is suffering from perplexing issues like intermittent stalling, a persistent check engine light, rough idling, or a complete no-start condition, the root cause is often a failing Powertrain Control Module (PCM). As the central computer of your vehicle, the PCM is responsible for managing everything from fuel injection and ignition timing to transmission shifting and emissions control. When it begins to fail, it can create a cascade of problems that are frustrating and difficult to diagnose.
This replacement PCM, part number 12200411, is the definitive solution to restore your vehicle’s performance, reliability, and drivability. We take the guesswork and hassle out of the repair process. Unlike a generic module from a parts store or salvage yard, this unit comes professionally programmed to your vehicle’s specific Vehicle Identification Number (VIN). This ensures seamless integration with your truck’s existing systems, effectively making it a plug-and-play replacement.
From the Diagnostic Bay
We had a 2002 Silverado 2500 come into the shop with an issue that had stumped two other mechanics. The truck would run perfectly for 20-30 minutes and then suddenly die, refusing to restart for an hour. There were no consistent trouble codes, just a random U-code for lost communication. After checking all the usual suspects—fuel pump, crank sensor, ignition system—we focused on the PCM. We noticed that heat seemed to be a factor. By carefully heating the PCM with a heat gun, we could replicate the stall every time. The internal circuit board had developed a microscopic crack that would expand when hot, breaking the connection. Installing a VIN-programmed PCM like this one solved the problem instantly, saving the customer from chasing phantom issues and replacing perfectly good parts.
Common Symptoms of a Failing GM PCM
- ✔ Persistent Check Engine Light (CEL) with various or no specific codes.
- ✔ Engine stalling or shutting off unexpectedly while driving.
- ✔ No-start or hard-start conditions, especially when the engine is warm.
- ✔ Noticeable decrease in fuel economy.
- ✔ Rough or erratic engine idle.
- ✔ Harsh or delayed transmission shifting.
- ✔ Failure to pass state emissions testing.
- ✔ Communication errors when using a diagnostic scan tool.

Frequently Asked Questions
Do I need to get this PCM programmed?
No. This PCM comes fully programmed to your vehicle’s VIN before it is shipped. Simply provide your VIN during or after checkout, and we handle the rest. It arrives ready for installation.
Where can I find my vehicle’s VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on your vehicle’s registration, insurance card, or on the driver’s side of the dashboard, visible through the windshield.
Will I need to perform a security relearn procedure?
In many cases with these GM vehicles, a simple security relearn procedure is required after installation. This typically involves turning the key to the ‘ON’ position for 10-15 minutes, then off, and repeating two more times. This allows the new PCM to sync with your vehicle’s anti-theft system.
What if my original part number is different?
This module is a compatible replacement for several part numbers, including 12201281, 12576160, and 52369718. As long as your vehicle is listed in the compatibility chart, this PCM will function correctly once programmed to your VIN.
Will this fix my check engine light?
If the check engine light and associated symptoms are caused by a faulty PCM, then yes, this replacement part will resolve the issue. It’s crucial to ensure other potential problems (like faulty sensors or wiring) have been ruled out.
