An Expert’s Note on Programming
As a technician with over two decades of experience, I’ve seen countless vehicle owners and even professional shops get stuck with modules pulled from other vehicles. These units almost never work correctly out of the box. They contain the wrong software, security information, and option content for your specific H2. Our process eliminates that entire headache.

This is the single most critical step for a successful and lasting repair.

The core of your truck’s powertrain management, a properly functioning 2007 Hummer H2 ECM is essential for both power and reliability.
Frequently Asked Questions
Is this ECM really ‘plug and play’?
Yes. Because we program the module to your vehicle’s specific VIN, it is ready for installation upon arrival. In the vast majority of 2007 GM vehicles, this eliminates the need for any additional programming or complicated security relearn procedures at a dealership.
What information do I need to provide for programming?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we have this information to program it correctly.
Where can I find my VIN?
Your VIN can be found on a metal plate on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
How can I be sure my old ECM is the problem?
While the symptoms listed above are strong indicators, a definitive diagnosis from a qualified technician is always the best course of action. Common diagnostic trouble codes (DTCs) related to internal processor failure or communication loss often point directly to a faulty ECM.
Will this fit other vehicles besides the Hummer H2?
Yes, this ECM is compatible with a wide range of 2007 GM trucks and SUVs, including the Cadillac Escalade, Chevy Tahoe/Suburban/Silverado, and GMC Yukon/Sierra, among others. Please check the detailed fitment list to confirm compatibility with your specific model.
What is the warranty on this part?
This unit is backed by our one-year replacement warranty, giving you confidence in your purchase.
