Frequently Asked Questions
Do I need to do any programming or flashing myself?
No. We handle all the programming before the unit ships. It will arrive at your door flashed with the latest GM software updates, tailored specifically to the VIN you provide. The only step you may need to perform is a simple security relearn procedure, which typically involves cycling the key and can be done in your driveway in about 10-15 minutes.
Where do I provide my vehicle’s VIN?
After you complete your purchase, we will send you an email requesting your vehicle’s 17-digit VIN. You can also add it to the order notes during checkout. We cannot ship your part until we have this information to ensure correct programming.
Is this ECM compatible with other part numbers?
Yes. This module is a direct replacement for several common GM part numbers, including 12589297, 12597121, 12603892, and 19210738. If your original module has any of these numbers, this part will work for you.
My vehicle isn’t an Avalanche. Will this still fit?
Yes, this ECM fits a very wide range of 2007 GM trucks, SUVs, and even some cars. Please check the detailed fitment list on this page to confirm compatibility with your specific make and model, such as the Silverado, Tahoe, Suburban, Escalade, Sierra, Yukon, and others.
What is the security relearn procedure?
For most GM vehicles of this era, it’s a simple key-on/key-off process. You’ll typically turn the key to the ‘ON’ position for 10 minutes, then ‘OFF’ for 10 seconds, and repeat this cycle three times. This allows the new ECM to synchronize with your vehicle’s anti-theft system. We can provide specific instructions for your vehicle upon request.
What does the warranty cover?
This unit is backed by our one-year replacement warranty. In the unlikely event of a module failure within one year of the purchase date, we will provide a direct replacement unit.
