Expert Insight: More Than Just a Computer
The ECM in a vehicle like the Hummer H2 is the brain of the entire operation.

Using the latest GM updates ensures all these systems speak the same, correct language, preventing the cascading electronic issues that often plague vehicles with a failing module.
Frequently Asked Questions
Do I need to do anything after installing this ECM?
In many cases, a security relearn procedure (often called a Passlock or Passkey relearn) is required, which you can typically do yourself in about 15-30 minutes. Some vehicles may also require a Crankshaft Position Sensor (CASE) relearn, which needs a compatible scan tool. We include instructions for the security relearn procedure with your order.
How do I provide my vehicle’s VIN?
Simply enter your 17-digit VIN in the designated field on the product page or in the notes section at checkout. If you forget, we will contact you via email after your purchase to retrieve it before we program and ship your 2007 Hummer H2 ECM.
Is this the correct part for my vehicle?
This module is compatible with the part numbers 12589297, 12597121, 12603892, and 19210738. Please check the part number on your original module to ensure a match. If you are unsure, please contact us with your VIN and we will be happy to verify compatibility for you.
What does “pre-programmed” mean?
“Pre-programmed” or “flashed” means we load your vehicle’s specific software and calibration files onto the module using your VIN before it leaves our facility. This ensures the ECM is ready to be installed and communicate with your vehicle’s other systems.
What is the warranty on this part?
This unit is backed by our one-year replacement warranty. This provides coverage against defects in the module for a full year from the date of purchase.
