Get Your H3 Running Right Again
Is your 2007 Hummer H3 suddenly running rough, stalling, or refusing to start? A faulty Powertrain Control Module (PCM) is often the culprit behind these frustrating and complex issues. Your truck’s PCM is its brain, controlling everything from fuel delivery and spark timing to transmission shifting. When it fails, it can bring your entire vehicle to a standstill. This replacement PCM is the definitive, no-guesswork solution to restore your truck’s performance and get you back on the road with confidence.
Common Symptoms of a Failing H3 PCM & Your Solution
If you’re experiencing any of the following, a failing computer is the likely cause. This pre-programmed module is designed to solve these exact problems:
- Check Engine Light (CEL) Illumination: Persistent or flashing check engine light with various diagnostic trouble codes (DTCs), especially for communication errors or multiple unrelated sensor failures.
- No-Start or Hard-Start Condition: The engine cranks but won’t start, or takes an excessive amount of time to fire up.
- Poor Engine Performance: Noticeable loss of power, rough idling, engine stumbling, or sudden stalling while driving.
- Erratic Transmission Shifting: Harsh shifts, delayed engagement, or getting stuck in a single gear (limp mode).
- Communication Failures: Your diagnostic scan tool cannot communicate with the 2007 Hummer H3 PCM.
Instead of paying for expensive diagnostic fees and dealership programming, this unit arrives ready for installation. We take your vehicle’s unique VIN and flash the module with the latest, most stable software directly from GM, ensuring it’s a perfect match for your truck’s specific configuration.

An Expert’s Note on VIN Programming
“I’ve seen it countless times: a customer buys a used computer online, plugs it in, and the truck still won’t start. That’s because the PCM is locked to the original vehicle’s VIN and security system. Our process eliminates that entire headache. By programming the 2007 Hummer H3 PCM to your VIN before it even leaves our facility, we’re ensuring it communicates seamlessly with the other modules in your truck. It’s the single most important step for a successful repair, and it’s the core of what we do.”
Frequently Asked Questions
Do I need to do anything after installing the PCM?
In most cases, you will need to perform a simple security relearn procedure, which can often be done without special tools and takes about 30 minutes. This process pairs the new PCM to your vehicle’s existing anti-theft system and keys. We include instructions to guide you through this step.
How do I provide my Vehicle Identification Number (VIN)?
After you complete your purchase, we will contact you via email to request your vehicle’s 17-digit VIN. We cannot program and ship your module until we receive this information, so please provide it promptly to avoid delays.
Is this the correct part for my vehicle?
This PCM is a confirmed fit for the 2007 Hummer H3 as well as many other 2007-2008 GM models like the Isuzu Ascender, GMC Envoy, Chevy Colorado, and Saab 9-7X. The crucial factor is our VIN-specific programming, which makes it compatible. If you have any doubts, please contact us with your VIN before ordering.
What does “pre-programmed” mean exactly?
It means we use your VIN to load the correct, factory-approved software and calibrations for your vehicle’s specific engine, transmission, and options. This makes the 2007 Hummer H3 PCM a true plug-and-drive component, unlike a generic or used module that would require expensive dealer flashing.
What if my original part number is 12602010 instead of 19210067?
Part numbers 12602010 and 19210067 are interchangeable hardware. The critical component is the software, which we program specifically for your vehicle using your VIN. As long as your vehicle is on the compatibility list, this module will function correctly regardless of which of these two numbers was on your original unit.
