Expert Insight: Back on the Road in an Afternoon
We recently worked with a customer whose 2017 Traverse was constantly stalling in traffic—a major safety concern for their family. The dealership quoted them a huge bill and a week-long wait. We sent them this pre-programmed 2017 Traverse ECM 12666070. Their local mechanic installed it in under an hour, the stalling issue was completely resolved, and they were back to their daily routine with a safe, reliable vehicle for a fraction of the cost and time.

Frequently Asked Questions
Do I need to do any programming myself?
No. We handle all the programming for you before shipment. We use the VIN you provide during checkout to load the correct GM software and key data, so the unit is ready to be installed upon arrival. You may need to perform a simple security relearn procedure, which typically involves cycling the key and can be done in your driveway without any special tools.
How do I provide my Vehicle Identification Number (VIN)?
After you complete your purchase, you will receive instructions on how to send us your 17-digit VIN. We cannot ship your part until we receive this information, as it is essential for the programming process.
Is this compatible with my vehicle?
This module is a guaranteed fit for a 2017 Chevrolet Traverse and other GM models listed in the fitment guide, provided your original part number is 12666070, 12667002, or 12667189. Please verify your original part number before ordering to ensure compatibility.
What tools are needed for installation?
Installation typically requires basic hand tools like a socket set and screwdrivers. It is critical to disconnect the vehicle’s battery before starting the replacement process. While many experienced DIY-ers can perform the swap, we always recommend installation by a qualified mechanic to ensure everything is handled correctly.
Will this fix my check engine light?
This ECM will resolve any check engine light and diagnostic trouble codes (DTCs) that are directly caused by a faulty engine computer. However, if the light is on due to other issues (e.g., a bad oxygen sensor or catalytic converter), those problems will still need to be addressed separately. A proper diagnosis is always recommended.
