We make it simple: provide your VIN, and we’ll ship you the brain your truck needs to perform at its best.
Frequently Asked Questions
What is a VIN and where do I find it?
The VIN (Vehicle Identification Number) is a unique 17-digit code for your vehicle. You can typically find it on a plate on the 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 a simple plug-and-play installation?
This module is programmed to be plug-and-play regarding engine and transmission operation. However, as stated in the listing, you or your mechanic may need to perform a security or ‘theft deterrent’ relearn procedure after installation for the vehicle to start. This is a standard security feature on all modern GM vehicles.
What is a ‘theft deterrent relearn’?
It’s a security procedure that syncs the new ECM to your vehicle’s existing anti-theft system and keys. This procedure requires a compatible professional scan tool with access to GM’s online system (Tis2web/Techline Connect). Most professional repair shops are equipped to perform this service.
Will this fix my truck’s specific problem?
This programmed 2016-2018 Silverado 1500 ECM is the correct solution for issues directly caused by a faulty control module. While it resolves the most common symptoms, we always recommend a proper diagnosis by a qualified technician to confirm the ECM is the point of failure before ordering.
Do I need to send my old ECM back?
No core charge or return is required for this part. You can keep or recycle your old module.
Does this fit models other than the Silverado 1500?
Yes. Please check the detailed fitment list in the description. This ECM is compatible with a wide range of GM trucks and SUVs from 2016-2018, including the Sierra, Tahoe, Yukon, Escalade, and more, when matched by part number.
