Restore Your Vehicle’s Performance and Reliability
Is your GMC Savana, Silverado, or Sierra suffering from frustrating issues like a persistent Check Engine Light, poor fuel economy, erratic shifting, or a no-start condition? A failing Powertrain Control Module (PCM) is often the culprit, leaving you with an unreliable vehicle and costly diagnostic headaches. This is your direct-fit, dependable solution. We provide a professionally programmed PCM, flashed with the latest GM software updates specific to your vehicle’s VIN, ensuring you get back on the road with confidence and without a mandatory trip to the dealership.
Common Symptoms of a Failing GM PCM
If your vehicle is experiencing any of the following, a faulty engine computer may be to blame. This module is the solution for correcting these performance-robbing problems:
- Check Engine Light (CEL): The light stays on despite other repairs, often with communication error codes (U-codes) or specific sensor codes that won’t clear.
- No-Start or Hard-Start: The engine cranks but refuses to start, or takes an excessive amount of time to fire up.
- Poor Performance: Noticeable loss of power, hesitation during acceleration, and rough idling.
- Reduced Fuel Economy: Your vehicle is consuming more fuel than usual due to incorrect air/fuel mixture calculations.
- Transmission Issues: Harsh or delayed shifting, as the PCM also controls transmission functions in many GM vehicles.
Features & Benefits: The Path to a Simple, Effective Repair

- Direct OEM Replacement
- Engineered to be a perfect match for the original part, this module fits precisely in the factory location with no modifications needed. It is compatible with part numbers 12200411, 12201281, 12576160, and 52369718.
- Skip the Expensive Dealership Visit
- By receiving a pre-programmed module, you bypass the high programming fees and scheduling delays associated with a dealership service appointment. Most owners with basic tools can complete the installation in under an hour.
Expert Insight: Why VIN Programming is Non-Negotiable
“Many people think they can just swap a PCM from a junkyard vehicle. This almost never works. The PCM is the brain of your vehicle, and it’s tied to your specific VIN, which dictates everything from the engine and transmission type to the axle ratio and even tire size. Without correct VIN programming, you’ll face immediate compatibility issues, a no-start condition due to the security system (VATS), and a persistent Check Engine Light. Our pre-flashing service removes that entire layer of complexity, delivering a part that’s truly ready for your specific vehicle right out of the box.”
Frequently Asked Questions
Where do I find my vehicle’s VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on your vehicle’s registration, your insurance card, or on the driver’s side of the dashboard, visible through the windshield.
Is this module difficult to install?
For most of the compatible vehicles like the Silverado, Sierra, and Savana, the PCM is located in the engine bay and is held in by a few bolts and electrical connectors. Installation is straightforward for anyone with basic mechanical skills. We always recommend disconnecting the battery before starting the replacement process.
Will I need to do anything after I install it?
In most cases, you will need to perform a security relearn procedure, also known as a VATS relearn. This is a simple process that 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 synchronize with your vehicle’s anti-theft system. Instructions are readily available online for your specific model.
Does this part come with a warranty?
Yes, all of our electronic modules are backed by a comprehensive warranty. Please see the warranty tab on this page for specific details and duration.
How do I provide my VIN after purchase?
After completing your purchase, you will receive an email with instructions on how to reply with your vehicle’s VIN. You can also add your VIN to the ‘notes’ section during checkout. We cannot program and ship your module until we receive your VIN.
Is this the correct part for my vehicle?
This module fits a wide range of 2001-2002 GM trucks, vans, and SUVs. Please review the detailed fitment list on this page to confirm compatibility. If your vehicle and original part number (e.g., 12200411) are listed, this is the correct replacement.
