Frequently Asked Questions
What information do you need from me to program the ECM?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). This is crucial for us to load the correct GM software and ensure compatibility.
Is this a true plug-and-play installation?
This ECM is programmed to your VIN for engine and transmission operation, making it plug-and-play in that regard. However, like most GM vehicles, you will likely need to perform a security relearn procedure (often called a Passlock or anti-theft relearn) to sync the new ECM with your vehicle’s keys. This procedure can typically be done without special tools and instructions are widely available online.
Will this computer fix my check engine light?
If the check engine light is caused by an internal failure of your old ECM, then yes, this part will resolve the issue. However, it is essential to have your vehicle properly diagnosed. This module will not fix problems related to other faulty sensors, wiring, or mechanical components.

This ECM fits several GM models, including the 2017-2019 Savana 3500, 2017-2018 Silverado/Sierra 2500 (6.0L), 2017-2018 Sonic, 2017-2018 Encore (1.4L, VIN B), and the 2017 Suburban 3500. Please verify your part number matches 12692201 or 12668986 for guaranteed fitment.
