Get Your GM Truck or Van Back on the Road, Fast.
Is your 2001-2002 GMC Savana, Chevy Express, or Silverado plagued by frustrating issues like a persistent check engine light, erratic shifting, stalling, or a complete no-start condition? These are classic signs of a failing Powertrain Control Module (PCM), the central computer of your vehicle. Don’t let a faulty module keep your workhorse off the job. This replacement PCM is the reliable, straightforward solution to restore your vehicle’s performance and get you back to work with confidence.
Common Symptoms & Your Solution
A failing PCM can cause a cascade of confusing problems. You might be experiencing one or more of the following:
- Check Engine Light (CEL) with communication-related codes (U-codes) or multiple, seemingly unrelated sensor codes.
- Poor Engine Performance: Rough idling, hesitation during acceleration, reduced power, and decreased fuel economy.
- Transmission Issues: Harsh or delayed shifting, or getting stuck in one gear (limp mode).
- No-Start Condition: The engine cranks but won’t start, often due to a lack of fuel injector or ignition coil command from the PCM.
- Intermittent Stalling: The engine shuts off unexpectedly while driving or at a stop.
This pre-programmed 2001-2002 Savana 1500 PCM is the definitive fix for these issues.

Expert Mechanic’s Insight
As a technician, I’ve seen countless early 2000s GM trucks and vans with baffling electronic issues. Often, the root cause is the original PCM. One of the biggest advantages of this unit isn’t just that it’s a replacement, but that it comes loaded with over two decades of software improvements from GM. Early calibrations often had minor bugs that could affect everything from idle quality on a cold morning to the firmness of a 2-3 gear shift under load. By installing a module with the latest software, you’re not just fixing a broken partโyou’re getting a more refined, reliable, and efficient operating system for your engine and transmission.
Frequently Asked Questions
What information do you need from me?
After you place your order, you must provide us with your vehicle’s 17-digit VIN. We cannot program or ship your module without it. The VIN is typically found on your driver’s side dashboard (visible through the windshield), on the driver’s door jamb sticker, or on your vehicle’s registration and insurance documents.
Is this part truly plug-and-play?
For most vehicles on the fitment list, yes. Once you install the module, you will need to perform a security relearn procedure, which is a simple process that pairs the new PCM to your vehicle’s anti-theft system. This procedure can be done without any special tools and instructions are readily available online. Some vehicles may also require a Crankshaft Variation Relearn (CASE relearn) for optimal performance, which requires a capable scan tool.
How do I know if my original PCM has failed?
Diagnosing a PCM requires ruling out other potential causes first (like wiring, sensors, or fuel delivery). However, if you are experiencing multiple, unrelated error codes, communication errors with a scan tool, or intermittent issues that can’t be traced to a specific component, the PCM is a very likely culprit. This is especially true if the problems worsen as the engine warms up.
Will this fix my specific problem?
This module is a direct solution for a failed PCM. If your vehicle’s issues are caused by a faulty module, this part will resolve them. It’s crucial to ensure your vehicle has been properly diagnosed, as this part will not fix problems related to other faulty mechanical or electrical components.
What if I have a different part number?
This module is a direct, compatible replacement for several part numbers, including 12200411, 12201281, 12576160, and 52369718. As long as your vehicle is on the compatibility list, this unit will function correctly once programmed to your VIN.
