Restore Peak Performance to Your GM Vehicle
Is your Chevrolet Equinox, GMC Terrain, or other GM vehicle suffering from frustrating issues like a persistent check engine light, poor fuel economy, stalling, or a complete no-start condition? These are classic signs of a failing Engine Control Module (ECM), the critical computer that manages your vehicle’s engine. Don’t let a faulty ECM keep you sidelined. This genuine, used GM ECM is the reliable, cost-effective solution to get you back on the road with confidence.
Common Symptoms & Your Solution
A failing ECM can cause a cascade of confusing problems. You might be experiencing one or more of the following:
- Check Engine Light (CEL) Illumination: Often with codes related to sensors, communication, or processor faults.
- Engine Stalling or Misfiring: The engine may run rough, hesitate on acceleration, or shut off unexpectedly.
- No-Start Condition: The engine cranks but refuses to start, indicating the ECM isn’t managing fuel or spark correctly.
- Poor Performance & Fuel Economy: A noticeable drop in power and more frequent trips to the gas station.
- Transmission Shifting Issues: The ECM works with the transmission controller, and a fault can lead to harsh or erratic shifting.
This unit is your direct-fit, plug-and-play solution. We take the guesswork out of the repair by pre-programming this programmed 2013-2016 Equinox ECM to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This ensures all factory settings and vehicle-specific options are correctly loaded, restoring the precise performance your vehicle was designed for.

Expert Insight: Why VIN Programming is Non-Negotiable
As a 20-year veteran technician, I’ve seen countless issues arise from improperly matched control modules. Your vehicle’s VIN isn’t just a serial number; it’s a blueprint for its specific features, from the engine and transmission type to its emissions equipment and security system. Installing a non-programmed ECM is like giving your vehicle amnesia. It won’t recognize its own components, leading to a no-start condition or a dashboard full of warning lights. Our VIN-flashing service ensures this programmed 2013-2016 Equinox ECM communicates flawlessly with your vehicle’s network from the moment you connect it, saving you immense time, frustration, and money.
Frequently Asked Questions
Is any additional programming required after installation?
No. We flash the module with the latest GM updates using your VIN, so it arrives ready to install. In some cases, a simple security or crankshaft position sensor relearn procedure may be necessary, which can be performed by many local repair shops or with a capable scan tool.
How do I provide my VIN?
After you complete your purchase, simply send us a message with your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information. You can typically find your VIN on your vehicle’s dashboard (visible through the windshield) or on your insurance and registration documents.
How can I be sure this ECM will fix my problem?
While the symptoms listed are very common for a failing ECM, it’s always best to have a professional diagnosis performed. This ensures you are replacing the correct part and avoids unnecessary expenses. This programmed 2013-2016 Equinox ECM is the definitive solution for a confirmed module failure.
Is this a new part?
No, this is a genuine, used OEM part that has been carefully sourced from a salvaged vehicle. Each unit is inspected and then programmed to ensure it is ready for service in your vehicle.
What does the warranty cover?
This unit is backed by our one-year replacement warranty. This covers the part itself in the unlikely event of a failure within one year of the purchase date. Please contact us for complete details.
