Get Your Truck Back on the Road, Fast.
Is your 2001-2002 GMC Yukon XL 2500 running rough, stalling, or showing a persistent Check Engine Light? A failing Powertrain Control Module (PCM) is often the culprit, disrupting everything from fuel delivery to transmission shifting. This isn’t just an inconvenience; it’s a reliability issue that can leave you stranded. Get back the dependability you count on with this fully programmed PCM, designed to restore your vehicle’s factory performance and get you back to work and life without delay.
Is Your Vehicle Showing Signs of a Bad PCM?
A faulty engine computer can cause a wide range of frustrating and difficult-to-diagnose problems. If you’re experiencing any of the following, it’s a strong indication that your PCM needs attention:
- Check Engine Light: Specifically for internal module errors like DTC P0601 (Internal Control Module Memory Check Sum Error) or P0606 (ECM/PCM Processor Fault).
- Engine Performance Issues: Unexplained stalling, rough idling, hesitation during acceleration, or a noticeable decrease in fuel economy.
- No-Start Condition: The engine cranks but refuses to start, even with a good battery and starter.
- Erratic Transmission Shifting: Harsh or delayed shifts that aren’t related to a mechanical transmission problem.
- Communication Errors: Your mechanic’s scan tool is unable to communicate with the engine computer.
This replacement module is the definitive solution to these issues, providing a reliable and correctly calibrated ‘brain’ for your vehicle’s powertrain.

Expert Insight: Why VIN Programming is Non-Negotiable
“In early 2000s GM vehicles, the PCM is the central hub for the entire powertrain. It doesn’t just manage the engine; it communicates constantly with the transmission control module, the anti-lock brake system, and even the instrument cluster. Simply installing a used module from another vehicle will almost always result in system conflicts and a no-start condition due to the vehicle’s anti-theft system (PassLock/VATS). By programming the module to your exact VIN, we ensure all these components recognize each other and work together seamlessly, just as they did from the factory. It’s the only way to guarantee a successful and lasting repair.”
Extensive Compatibility
This PCM is a direct replacement for part numbers 12200411, 12201281, 12576160, and 52369718 and fits a wide range of GM trucks, vans, and SUVs from 2001-2002. Please verify your part number and vehicle fitment before ordering.
Frequently Asked Questions
Why do you need my VIN?
Your Vehicle Identification Number (VIN) is essential because it contains specific information about your truck’s engine, transmission type, emissions system, and other factory-installed options. We use this information to load the exact, correct GM software onto the module, ensuring it functions perfectly with your specific vehicle configuration.
Is this module difficult to install?
The physical installation is straightforward for anyone with basic mechanical skills. On most GM trucks and SUVs like the Yukon, the PCM is located under the hood, typically on the driver’s side fender well under the battery tray. It involves disconnecting the battery, unplugging a few electrical connectors, and unbolting the module. However, professional installation is always recommended if you are not comfortable with automotive repairs.
Will I need to do anything after installing it?
In most cases, after installation, you will need to perform a security relearn procedure, often called a “CASE Relearn” or “VATS Relearn.” This syncs the new PCM with your vehicle’s anti-theft system and ignition keys. This procedure is simple and can typically be done without special tools. We include instructions to guide you through the process.
Is this a new or used part?
This is a high-quality, reconditioned OEM part. Each unit is sourced from an original vehicle, then professionally inspected, cleaned, and electronically tested. It is then programmed with the latest software for your vehicle, ensuring reliable, long-term performance.
