Restore Peak Performance to Your GM Truck, Van, or SUV
Is your 2001-2002 GM vehicle suffering from frustrating issues like a persistent check engine light, stalling, rough idling, or a complete no-start condition? These are classic signs of a failing Powertrain Control Module (PCM), the central computer that governs your engine’s performance, fuel delivery, and transmission shifting. A faulty PCM can leave you stranded and lead to poor fuel economy and potential damage to other components. This direct-fit Engine Control Module, part number 12201281, is the definitive solution to restore your vehicle’s reliability and drivability.
The Brain of Your Vehicle, Made New Again
The PCM is arguably the most critical electronic component in your vehicle. It processes data from dozens of sensors to make thousands of real-time adjustments to the fuel injectors, ignition timing, and transmission solenoids. When it fails, the entire powertrain system is compromised. Our replacement module is meticulously prepared to meet and exceed original factory specifications. We take the guesswork out of the repair by programming the module specifically for your vehicle using the VIN you provide. This ensures that all factory parameters, anti-theft systems, and vehicle-specific options are correctly configured right out of the box.
From the Diagnostic Bay
We had a 2002 GMC Sierra 2500 towed in that would start and run for about 15 minutes, then shut off and refuse to restart until it cooled down completely. The owner had already replaced the fuel pump and crank sensor with no luck. Our diagnostic scan tool showed a P0601 ‘Internal Control Module Memory Check Sum Error’ and intermittent communication loss with the PCM. After verifying the power and ground circuits to the module were solid, we confirmed an internal PCM failure caused by heat soak. We installed a pre-programmed GM PCM 12201281, performed the 30-minute security relearn procedure, and the truck ran flawlessly. This simple replacement saved the customer from chasing down more phantom issues.
Why Choose Our Pre-Programmed GM PCM 12201281?
Replacing a PCM isn’t just about swapping a part. The module must be correctly programmed to communicate with the other systems in your vehicle. Dealerships charge a premium for the part and additional labor for programming. We simplify the process by handling the programming for you before we ship. Using the latest GM software updates, we ensure your engine operates with the most current and efficient calibrations available, often correcting issues that were present even in the original factory programming. This is a plug-and-play solution designed to get you back on the road quickly and affordably.
Is Your GM Truck or Van Showing These Signs?
- ✔ Persistent Check Engine Light (CEL)
- ✔ Engine stalling or cutting out unexpectedly
- ✔ Rough or erratic idling
- ✔ Harsh or incorrect transmission shifting
- ✔ A significant drop in fuel economy
- ✔ Complete no-start condition where the engine cranks but won’t fire

This module is a direct replacement for multiple part numbers, including 12200411, 12201281, 12576160, and 52369718. It fits a vast range of popular GM models such as the Silverado, Sierra, Tahoe, Yukon, Suburban, Savana, Express, and even performance vehicles like the Corvette and Camaro from the 2001-2002 model years. Please verify the fitment list to ensure compatibility with your exact vehicle.
Frequently Asked Questions
Is this PCM ready to install when I receive it?
Yes, this module comes fully programmed to your vehicle’s specific VIN. In most cases, you will need to perform a simple security relearn procedure (also known as a VATS relearn) after installation, which does not require any special tools.
How do I provide my vehicle’s VIN?
After placing your order, please send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot program and ship the module without it. You can typically find your VIN on the driver’s side dashboard (visible through the windshield) or on your vehicle’s registration.
What is the security relearn procedure?
The security relearn syncs the new PCM with your vehicle’s anti-theft system. The standard procedure involves turning the key to the ‘ON’ position for 10 minutes, then ‘OFF’ for 10 seconds, and repeating this cycle three times. Your vehicle’s manual may have specific instructions.
Will this fix my specific problem?
If your vehicle’s issues have been correctly diagnosed as a faulty PCM, this part is the solution. It will resolve problems like internal module errors (e.g., code P0601), communication failures, and faulty driver circuits. We always recommend proper diagnostics before ordering.
Do I need to send my old PCM (core) back?
This listing does not require a core return. You can keep your old module.
