Is Your GM Vehicle Running Poorly, Stalling, or Refusing to Start?
A faulty Powertrain Control Module (PCM) can be the hidden cause of frustrating and hard-to-diagnose issues. If you’re experiencing a persistent check engine light, erratic shifting, poor fuel economy, or a no-start condition, the brain of your vehicle’s engine may be failing. Don’t let a bad computer keep your reliable truck, van, or SUV off the road. This is the straightforward, dependable solution to restore your vehicle’s performance and get you back behind the wheel with confidence.

From the Technician’s Bench: A customer brought in a 2002 Express 3500 work van that was randomly stalling at idle, making it unreliable for his business. He had already replaced the fuel pump and several sensors with no luck. We traced the issue to an intermittent internal fault in the PCM. Installing our Programmed 12200411 PCM solved the problem immediately. The van ran perfectly, and he was back on the job the same day. Don’t waste time and money chasing symptoms when the root cause is the computer.
Frequently Asked Questions
How do I provide my Vehicle Identification Number (VIN)?
After completing your purchase, simply reply to your order confirmation email with the 17-digit VIN from your vehicle. You can find it on your driver’s side dashboard (visible through the windshield) or on your vehicle’s registration and insurance documents.
Will I need to do any programming after installation?
While the main engine and transmission programming is complete, you will need to perform a simple security relearn procedure, often called a CASE relearn or Passlock relearn. This syncs the new PCM to your vehicle’s anti-theft system and can typically be done without special tools. Instructions are readily available online for your specific model.
Is this a plug-and-play part?
Yes, for the most part. The module is a direct physical fit and comes electronically matched to your vehicle. The only additional step is the security relearn procedure mentioned above, which is a standard requirement when replacing a PCM on these vehicles.
How can I be sure this fits my vehicle?
This Programmed 12200411 PCM fits a wide variety of 2001-2002 GM trucks, vans, and SUVs. Please review the detailed fitment list on this page. The most important step is providing us with your VIN, which we use to guarantee it is programmed correctly for your exact make, model, and options.
What is the difference between a PCM, ECM, and ECU?
The terms are often used interchangeably. ECU (Electronic Control Unit) is a generic term. ECM (Engine Control Module) typically controls only engine functions. A PCM (Powertrain Control Module) is more integrated, controlling both the engine and the automatic transmission, which is standard for the vehicles this part fits.
