Restore Your Truck’s Dependability and Performance
Is your GMC Sierra or Silverado plagued by a persistent check engine light, erratic shifting, a no-start condition, or frustrating stalling? These are classic signs of a failing Engine Control Module (ECM), the brain of your vehicle. Don’t let a faulty computer keep your truck sidelined. This professionally programmed ECM is the definitive, reliable solution to get you back to work and back on the road with confidence.
Common Symptoms & Your Solution
A failing ECM can cause a cascade of issues that are often misdiagnosed. If you’re experiencing any of the following, this module is your answer:
- Persistent Check Engine Light (CEL) with communication-related codes (e.g., U-codes, P0601, P0606)
- Engine stalling, stumbling, or rough idling
- Unexplained drop in fuel economy
- Transmission shifting harshly or at the wrong times
- Complete no-start condition where the engine cranks but won’t fire
- Intermittent electrical problems that seem to have no source
Instead of wrestling with a used module from a junkyard that will require an expensive trip to the dealer for programming, this unit arrives ready for installation. We use your vehicle’s VIN to flash this module with the latest, most stable software updates from GM, ensuring it communicates perfectly with your truck’s specific systems. This is the most efficient way to install a replacement programmed 2014-2016 Sierra 1500 ECM and solve those nagging electronic gremlins for good.

An Expert’s Note on Programming: As a technician with over two decades of experience, I’ve seen countless vehicle owners waste time and money installing un-programmed control modules. A module without the correct VIN-specific software simply cannot communicate with the other computers in your vehicle, like the Body Control Module or Transmission Control Module. This leads to a no-start condition or a dashboard full of warning lights. Our process of programming the module *before* it ships completely eliminates this critical point of failure, making your repair job simpler and more successful.
This module is the heart of your engine management system. By choosing a professionally programmed 2014-2016 Sierra 1500 ECM, you’re not just buying a part; you’re investing in a reliable fix that restores your truck to its peak operational condition.
Frequently Asked Questions
What do I need to do after installing the module?
In most cases, you will need to perform a security relearn procedure, which can typically be done without special tools and takes about 30 minutes. Instructions are readily available online for your specific model. Some vehicles may also require a Crankshaft Position Sensor (CASE) relearn, which requires a capable scan tool.
How 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 will then program the module to match your vehicle’s exact specifications before shipping it to you.
Will this fit vehicles other than the Sierra 1500?
Yes, this ECM is compatible with a wide range of 2014-2016 GM vehicles, including the Chevy Silverado 1500, Yukon, Tahoe, Suburban, Escalade, and even some Cadillac and Corvette models. Please check the detailed fitment list to confirm compatibility with your specific vehicle.
What if my original part number isn’t on your list?
The part numbers listed are the most common, but there may be others. If you don’t see your exact number, please contact us with your VIN. We can verify compatibility and ensure you receive the correct module for your vehicle.
Is this a difficult part to replace?
For someone with moderate mechanical skill, this is a straightforward job. The ECM is typically located in the engine compartment and is held in place by a few bolts and electrical connectors. The most important step is to disconnect the battery before starting the replacement.
