Expert Insight from Our Technicians
Before installing a new ECM, it’s critical to ensure the original cause of failure has been addressed. Often, an ECM fails due to external factors like a shorted-out sensor, a faulty ignition coil, or a damaged wiring harness. A simple 5-volt reference check on your main sensors can save you from damaging the replacement module. Taking a few extra minutes to verify the health of the surrounding electrical system ensures your new programmed 2017 GMC Yukon ECM has a long, reliable service life.
Frequently Asked Questions
What exactly is a VIN-programmed ECM?
A VIN-programmed ECM is an engine computer that has been loaded with the specific software and calibrations for your exact vehicle using its unique 17-digit Vehicle Identification Number (VIN). This ensures it works seamlessly with your engine, transmission, and options, just like the original one from the factory.
Do I need to do anything after installation?
In many cases, the vehicle will start and run correctly. However, due to GM’s security systems, a ‘theft deterrent relearn’ procedure may be required if the vehicle does not start. This links the new ECM to your vehicle’s security system and requires a professional scan tool like the GM Tis2web/Techline Connect system. Other vehicle-specific relearns, like for the crankshaft position sensor, may also be necessary.
How do I provide my VIN?
After you complete your purchase, you will need to send us your vehicle’s 17-digit VIN. You can typically find this on your driver’s side dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Is this the correct ECM for my vehicle?
This module fits a wide range of 2016-2018 GM vehicles, including the Tahoe, Suburban, Silverado, Sierra, Escalade, and more. Please check the detailed fitment list on this page and match your original part number to one of the numbers listed to ensure compatibility. If you’re unsure, feel free to contact us with your VIN.
