Is Your Silverado Running Rough? Restore Its Power and Reliability.
If you’re dealing with a persistent check engine light, poor fuel mileage, stalling, or other frustrating engine performance problems in your 2014-2016 Silverado 1500, a failing Engine Control Module (ECM) is a likely culprit. The ECM is the brain of your truck’s engine, managing everything from fuel injection and ignition timing to transmission shifting. When it fails, it can cause a wide range of issues that can leave you stranded. Don’t let a faulty computer dictate your truck’s performance. This direct-replacement ECM is the definitive solution to get your vehicle running like new again.
We take the guesswork and high dealership costs out of the equation. Simply provide us with your vehicle’s VIN during checkout, and our technicians will program this module with the latest, most stable software updates directly from GM. This ensures perfect compatibility and optimal performance for your specific vehicle configuration. Your new ECM arrives ready for installation, saving you a trip to the dealer and expensive programming fees.
From the Diagnostic Bay
We had a 2015 Sierra come in with the strangest problem. The owner said it would randomly lose power and the transmission would shift hard, but there were no consistent codes. We checked everything—fuel pressure, sensors, wiring—and couldn’t find a thing. On a hunch, we monitored the live data from the ECM and noticed the processor was dropping data packets intermittently. We swapped in one of our pre-programmed modules, performed the security relearn, and the truck ran perfectly. It’s a classic case of a failing computer causing phantom issues that are impossible to trace without replacing the core component.
Symptoms of a Failing 2014-2016 Silverado 1500 Engine Module
- ✔ Persistent Check Engine Light (CEL) with various trouble codes.
- ✔ Engine stalling, misfiring, or running rough at idle.
- ✔ A noticeable decrease in fuel economy.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ The vehicle fails to start, even with a good battery and starter.
- ✔ Loss of communication with the module when using a diagnostic scan tool.
- ✔ Warning messages on the instrument cluster like “Service StabiliTrak” or “Reduced Engine Power.”
Plug-and-Play Solution with VIN Programming
This isn’t just a part; it’s a complete service. The key to a successful ECM replacement is the programming. An unprogrammed module from a parts store or salvage yard simply will not work. Our process is simple: you order the part, provide your VIN, and we handle the complex programming. This ensures that when you receive your 2014-2016 Silverado 1500 Engine Module, it correctly communicates with all other systems in your truck, including the ignition, anti-theft system, and transmission. For most installations, a simple security relearn procedure (which you can often do yourself) is all that’s needed to finalize the process.

Frequently Asked Questions
Why do you need my VIN?
Your Vehicle Identification Number (VIN) is essential for us to program the module with the exact software and calibrations your truck had from the factory. This ensures all systems, options, and the anti-theft system function correctly.
Is this part difficult to install?
The physical installation is straightforward for someone with basic mechanical skills. On the Silverado/Sierra, it’s located in the LH front of the engine compartment. After installation, you will need to perform a security relearn procedure, which can often be done without special tools. Instructions are widely available online.
Will this fix my check engine light?
If the check engine light is caused by a faulty ECM, then yes, this part will resolve the issue. However, it’s always best to have the codes read by a professional scanner to confirm the diagnosis before ordering.
What is a security relearn procedure?
This is a simple procedure that syncs the new ECM with your vehicle’s anti-theft system and keys. It typically involves a sequence of turning the key on and off for specific time intervals. It does not require a dealer visit in most cases.
Is this a new or used part?
This is a high-quality, tested, and verified used OEM component. Each module is thoroughly inspected and then programmed with the latest GM software for your specific VIN to ensure reliability and performance.
