Restore Peak Performance to Your GM Truck or SUV
Is your Sierra, Silverado, or Tahoe suffering from baffling electrical issues, a persistent check engine light, or a frustrating no-start condition? A failing Engine Control Module (ECM) is often the culprit, leaving your dependable vehicle sidelined. This is the definitive solution: a professionally programmed ECM, flashed with the latest official GM software and tailored specifically to your vehicle’s Vehicle Identification Number (VIN). Get back to work and back on the road with a component designed to restore your vehicle’s factory performance and reliability. This Programmed 2016-2018 Sierra 1500 ECM is your first step toward a lasting repair.
Common Symptoms & Your Solution
A faulty ECM can manifest in numerous ways, often mimicking other component failures. If you’re experiencing any of the following, this module is the likely solution:
- Complete no-start or intermittent starting issues
- Poor engine performance, rough idling, or stalling
- Reduced fuel economy
- Check Engine Light (CEL) with communication-related trouble codes (e.g., U0100, P0606)
- Erratic transmission shifting or gear selection problems
- Unexplained warning lights on the instrument cluster
Our process eliminates guesswork. By programming the module to your VIN, we ensure it has the correct calibration files for your truck’s specific engine, transmission, and emissions equipment, directly addressing software conflicts and hardware failure.

A Note From Our Technicians: After installing your new ECM, your vehicle’s anti-theft system will prevent it from starting. This is a normal security feature. A ‘Vehicle Theft Deterrent Relearn’ is a required final step to sync the new module to your keys.

Frequently Asked Questions
What information do I need to provide?
After you place your order, you MUST provide us with your 17-digit Vehicle Identification Number (VIN). We cannot program or ship the module without it.
Is this a simple plug-and-play part?
While it is a direct physical fit (‘plug’), it is not ‘play’. After installation, a Vehicle Theft Deterrent Relearn is required using a GM-specific scan tool. Other procedures, like a crankshaft variation relearn, may also be necessary depending on your vehicle. This is the responsibility of the installer.
Will this fix my truck’s problem for sure?
This module will correct any issues directly caused by a failing ECM. However, it is crucial that your vehicle has been properly diagnosed by a professional. This part will not fix problems related to other faulty sensors, wiring, or mechanical components.
Do I need to send my old computer back?
No. There is no core charge or need to return your original ECM, saving you time and shipping costs.
Does this fit vehicles other than the Sierra 1500?
Yes. This ECM is compatible with a wide range of GM trucks and SUVs from 2016-2018, including the Silverado, Tahoe, Yukon, and Escalade. Please refer to the detailed fitment list on this page to confirm compatibility with your specific model.
