Get Your Savana Back on the Job, Fast
When your GMC Savana is down, your business is on hold. A faulty Engine Control Module (ECM) can be the source of frustrating, hard-to-diagnose issues that cost you time and money. This isn’t just a replacement part; it’s a complete, ready-to-install solution designed to get your workhorse running reliably again. We take the guesswork out of the repair by pre-programming this module to your van’s specific VIN, ensuring it works correctly right out of the box.
Common Symptoms & Your Solution
If your van is experiencing any of the issues below, a failing engine computer is the most likely culprit. This module is the definitive solution for restoring your vehicle’s performance and dependability.
- Check Engine Light: Persistent or intermittent check engine light with communication-related trouble codes (e.g., P0601, P0606, U-codes).
- No-Start or Hard Starting: The engine cranks but refuses to start, or takes an excessive amount of time to fire up.
- Stalling and Poor Performance: Unexpected stalling, rough idling, hesitation during acceleration, and a noticeable drop in fuel economy.
- Erratic Shifting: The transmission may shift harshly, get stuck in gear, or not shift at all, as the ECM plays a key role in transmission control.
- Component Failures: Seemingly random issues with fuel injectors or ignition coils can often be traced back to a faulty ECM driver circuit.

An Expert’s Note on Intermittent Problems
“I’ve seen it a hundred times. A contractor’s van runs fine for days, then suddenly starts stalling at intersections. They replace sensors, check wiring, but the problem persists. These ‘ghost’ issues are a classic sign of a failing ECM. The internal components break down under heat and vibration, causing problems that don’t always set a clear code. Replacing the brain of the operation with a properly programmed 2010-2014 Savana 1500 ECM 12633238 isn’t just swapping a part; it’s restoring the vehicle’s core stability and saving the owner from endless, costly diagnostic chases.”
Don’t let a faulty computer keep your business parked. This pre-programmed 2010-2014 Savana 1500 ECM 12633238 is the most reliable and efficient way to solve complex electronic issues and get back to what matters most. Simply provide your VIN during checkout, and we’ll handle the rest.
Frequently Asked Questions
What exactly is VIN programming?
VIN programming involves loading your vehicle’s unique 17-digit Vehicle Identification Number and its associated software into the ECM. This ensures the computer communicates correctly with your van’s specific engine, transmission, and options package, just like the original unit from the factory.
Is this part truly ‘plug and play’?
For the vast majority of vehicles, yes. Because we program it to your VIN, it arrives ready for installation. In some rare cases, a simple security relearn procedure (often called a CASE relearn or anti-theft relearn) may be required, which can be done without special tools. Instructions can be provided if necessary.
How do I provide my VIN?
After you complete your purchase, you will need to send us your vehicle’s 17-digit VIN. You can typically find this on your driver’s side door jamb sticker, the corner of your dashboard (visible through the windshield), or on your vehicle’s registration and insurance documents.
My original part number is 12633055. Will this work?
Yes. This ECM is a direct, compatible replacement for both 12633238 and 12633055. We will program it to function perfectly for your specific application.
Does this fit vehicles other than the Savana van?
Absolutely. This versatile ECM is the correct computer for a wide range of GM vehicles, including the Silverado, Sierra, Tahoe, Yukon, Suburban, Camaro, and Corvette within the specified model years. The key is that we program it specifically for the vehicle VIN you provide.
