Expert Insight: The Smart Repair Path
Many owners think their only option for a bad ECM is a brand-new, expensive unit from the dealership, which then requires a tow and a costly programming appointment. Our solution puts the power back in your hands. By providing us with your VIN, you receive a module that already has the correct operational software loaded. The only remaining step is a security handshake procedure (the vehicle theft deterrent relearn) that your mechanic—or a knowledgeable DIYer with the right tools—can perform on-site. This process saves you significant time, money, and logistical headaches, making it the most practical choice for a 2020-2021 GMC Canyon ECM 12669908 replacement.
IMPORTANT NOTICE: Upon purchase, you MUST provide us with your vehicle’s 17-digit VIN to program the module. After installation, a Vehicle Theft Deterrent Relearn procedure is required for the vehicle to start. Additional setup procedures, such as a crankshaft variation relearn, may also be necessary. This is the responsibility of the installer.
Don’t let a bad computer keep your truck sidelined. Order your pre-programmed 2020-2021 GMC Canyon ECM 12669908 today and get back on the road with confidence.
Frequently Asked Questions
What is a Vehicle Theft Deterrent Relearn?
It’s a security procedure that syncs the new ECM with your vehicle’s immobilizer system and keys. Without this ‘handshake,’ the truck’s security system assumes a theft is in progress and will prevent the engine from starting. This procedure requires a compatible professional scan tool or the GM TIS2WEB system.
Is this a new part?
No, this is a used, genuine OEM part that has been carefully sourced from a salvaged vehicle. We test the hardware to ensure it is fully functional before programming it with fresh, updated software specific to your VIN.
Where do I find my VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on your vehicle’s registration, insurance card, or on a metal plate on the driver’s side of the dashboard, visible through the windshield.
Will this fit other GM vehicles besides the GMC Canyon?
Yes. This module, identified by service number 12669908, fits a variety of GM vehicles from 2017-2019, including specific trims of the Equinox, Malibu, Cruze, ATS, Regal, Acadia, LaCrosse, and CTS. We program it for the specific vehicle associated with the VIN you provide.
What does the one-year replacement warranty cover?
Our one-year replacement warranty covers the ECM itself. If the module fails due to an internal defect within one year of the purchase date, we will provide a replacement unit. The warranty does not cover labor, diagnostic costs, or shipping.
