Expert Insight: Understanding the Security Relearn
After installing your new ECM, a “Vehicle Theft Deterrent Relearn” is a necessary final step. This is not a defect, but a standard security feature on all modern GM vehicles. It syncs the new ECM with your vehicle’s anti-theft system and keys. While we handle the complex VIN programming, this security handshake must be performed on the vehicle itself. A qualified technician with access to GM’s programming system (Tis2web/Techline Connect) can typically complete this procedure quickly, ensuring your vehicle starts and runs as it should.
Take control of your repair with a reliable, professionally programmed 2017 Yukon XL 1500 ECM 12674052. By providing us with your VIN upon purchase, you ensure that the brain of your vehicle’s engine is perfectly matched and ready for installation, getting you back on the road with minimal downtime.
Frequently Asked Questions
What information do I need to provide?
After you complete your purchase, you will need to send us your vehicle’s 17-digit Vehicle Identification Number (VIN). We cannot program and ship the module without it.
Is this ECM difficult to install?
The physical installation is typically straightforward, involving disconnecting the battery and swapping the module. However, post-installation procedures like the Vehicle Theft Deterrent Relearn and potentially a Crankshaft Variation Relearn are required. We recommend professional installation by a technician familiar with GM vehicles.
Will this fix my check engine light?
If a faulty ECM has been correctly diagnosed as the cause of your issues, this part will resolve the problem. It is essential to ensure a proper diagnosis has been performed, as other failing sensors or components can also trigger a check engine light.

No. This purchase does not require you to return your old ECM. There is no core charge associated with this part.
My original part number is slightly different, will this work?
This ECM, a genuine 2017 Yukon XL 1500 ECM 12674052, also replaces several other part numbers. Please check the fitment list provided. If you are still unsure, contact us with your VIN, and we will be happy to verify compatibility for you.
