Restore Peak Performance to Your GM Truck or SUV
Is your 2001-2002 Chevrolet Suburban 1500 running rough, shifting erratically, or failing to start? The Powertrain Control Module (PCM), often called the vehicle’s main computer, is the central command for your engine and transmission. When it begins to fail, it can cause a cascade of confusing and frustrating problems. This replacement PCM, part number 12200411, is the definitive solution to restore your vehicle’s original performance, fuel efficiency, and reliability.
We take the guesswork out of the repair. Unlike a generic module from a parts store, this unit comes pre-programmed specifically for your vehicle. Simply provide us with your Vehicle Identification Number (VIN) during checkout, and our technicians will flash the module with the latest, most stable software updates directly from GM. This ensures seamless integration and optimal function, eliminating the need for an expensive trip to the dealership for programming.
From the Diagnostic Bay
We had a 2002 Yukon XL come in that was a real head-scratcher. The owner had replaced the throttle body, multiple O2 sensors, and even the MAF sensor trying to chase down a persistent stalling issue and poor fuel economy. The check engine light was on with a handful of communication and sensor codes. After confirming all the new parts were working correctly, we hooked up our scope to the PCM’s 5-volt reference circuit. We found an intermittent voltage drop, a classic sign of an internal PCM failure. The computer was essentially starving its own sensors of the power they needed to report accurately. We installed a VIN-programmed 2001-2002 Suburban 1500 PCM (the Yukon uses the same module), performed the security relearn, and the truck ran perfectly. It’s a powerful reminder that sometimes the problem lies with the brain, not the limbs.
Is Your Suburban Showing Signs of a Failing PCM?
A faulty PCM can manifest in various ways, often mimicking other component failures. If you’re experiencing any of the following, your PCM may be the culprit:
- ✔ Check Engine Light is on with various, often unrelated, trouble codes (especially communication or reference voltage codes).
- ✔ Engine stalling, stumbling, or misfiring for no apparent reason.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ A complete no-start condition where the engine cranks but won’t fire.
- ✔ Decreased fuel economy and overall poor engine performance.
- ✔ Intermittent issues that seem to worsen as the engine warms up.
- ✔ Problems with the anti-theft system (Passlock/VATS) preventing startup.

Frequently Asked Questions
Do I need to do anything after installing this PCM?
Yes. While the main programming is done, you will likely need to perform a security relearn procedure (also known as a VATS relearn) and a Crankshaft Position Sensor (CASE) relearn. The security relearn can often be done without special tools and takes about 30 minutes. The CASE relearn requires a capable bi-directional scan tool. This is standard for any PCM replacement on these GM vehicles.
How do I provide my VIN number?
After you complete your purchase, you will receive instructions on how to send us your 17-digit VIN. We cannot ship your order until we receive this information, as the programming is specific to your vehicle.
Is this a plug-and-play part?
It is as close to plug-and-play as possible. We handle the difficult programming part. You simply need to install it and perform the final relearn procedures mentioned above. This saves you a significant amount of money compared to dealership programming.
Will this fix my transmission shifting problems?
If the shifting problems are caused by faulty electronic commands from the PCM, then yes, this will resolve them. The PCM controls shift points and line pressure. However, it will not fix internal mechanical failures within the transmission itself. A proper diagnosis is always recommended.
What if I have a different part number on my original module?
This module, 12200411, is the base part number for a family of modules. It is a compatible service replacement for part numbers 12201281, 12576160, and 52369718. As long as your vehicle is on the compatibility list, this module will function correctly once programmed to your VIN.
