Get Your Sierra Running Right Again
Is your dependable GMC Sierra suddenly plagued by frustrating electrical gremlins? A faulty Engine Control Module (ECM) can bring your workhorse to a standstill, causing issues from a simple check engine light to a complete no-start condition.

Common Symptoms & Your Direct Solution
A failing ECM can manifest in numerous ways. If you’re experiencing any of the following, a faulty module is a likely culprit:
- Persistent Check Engine Light (CEL) with communication-related codes (e.g., U-codes) or internal processor faults (e.g., P0606).
- Unexplained stalling or rough idling.
- Noticeable decrease in fuel economy.
- Hesitation or stumbling during acceleration.
- Complete no-start or intermittent starting problems.
- Transmission shifting issues or other module communication errors.

An Expert’s Note on VIN Programming
As a technician, I’ve seen countless issues arise from using generic, unprogrammed modules. A modern truck like your Sierra has dozens of options that are tied to the VIN—transmission type, gear ratios, emissions controls, and even tire size. Programming the ECM with your VIN isn’t just a suggestion; it’s a critical step. It tells the ‘brain’ of your truck exactly what ‘body’ it’s in. This precision programming prevents a cascade of frustrating compatibility errors, saving you from future diagnostic headaches and ensuring your truck runs exactly as the manufacturer intended.
Don’t let a bad computer keep your truck sidelined. By providing your VIN at checkout, you’re getting more than just a part; you’re getting a precision-matched component that restores the heart of your vehicle’s operating system. This is the smart, efficient way to replace your 2014-2016 Sierra 1500 ECM.
Frequently Asked Questions
Is this module ready to install right out of the box?
Yes, it comes fully programmed to your VIN. However, like any replacement ECM on this platform, you will need to perform a security relearn procedure (often called a Passlock or anti-theft relearn). This procedure is simple, requires no special tools, and typically takes about 30 minutes. Instructions are readily available online or in service manuals.
Where do I provide my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we have this information to program the module correctly.
Will this fix my check engine light?
If the check engine light and associated symptoms are caused by a faulty ECM, this part is the correct solution. It is crucial to have your vehicle properly diagnosed to confirm the original ECM is the point of failure before ordering. This part will not fix issues related to other failed sensors or mechanical components.
Does this fit other vehicles besides the Sierra 1500?
Yes. While this is a primary fitment for the 2014-2016 Sierra 1500 ECM, this module is also compatible with a wide range of GM vehicles from the same era, including the Silverado, Tahoe, Suburban, Yukon, Escalade, and others, as detailed in the fitment list. The VIN programming ensures it works perfectly for your specific model.
Do I need to send my old module (core) back?
No core charge or return is required for this part. You can keep or dispose of your old module at your convenience.
What does the warranty cover?
This unit is backed by our one-year replacement warranty, which covers the part against failure for one year from the date of purchase. Please contact us for any warranty service inquiries.
