Restore Peak Performance to Your GM Vehicle
Is your 2013-2016 Chevrolet Traverse, GMC Acadia, or other compatible GM vehicle suffering from perplexing issues like a persistent check engine light, poor fuel economy, erratic shifting, or even a no-start condition? These are classic signs of a failing Engine Control Module (ECM), the central computer responsible for managing your vehicle’s engine performance. A faulty ECM can create a cascade of problems that are often misdiagnosed, leading to costly and unnecessary repairs. This genuine used GM ECM, part number 12653998, is the direct-fit, reliable solution to get your vehicle running like new again.

When you order, simply provide us with your vehicle’s VIN. Our expert technicians will flash this module with the latest, most up-to-date GM factory software specific to your exact vehicle. This means the part arrives at your door ready for a straightforward, plug-and-play installation, with no need for an expensive trip to the dealership for programming. This is the most efficient way to replace your faulty 2013-2016 Traverse ECM.
From the Diagnostic Bay
We recently had a 2014 Acadia in the shop that was a real head-scratcher. The owner complained of random stalling at stoplights and a transmission that seemed to have a mind of its own, occasionally refusing to shift out of second gear. Multiple shops had replaced sensors and performed transmission services to no avail. After hooking up our advanced diagnostic tools, we noticed corrupt data packets being sent from the ECM. The internal processor was failing intermittently, causing these ghost-like problems. We installed a VIN-programmed ECM just like this one, and the vehicle immediately ran flawlessly. It’s a powerful reminder that the ECM is the true brain of the operation, and when it falters, it can manifest in very misleading ways.

- ✔️ Rough or unstable idle.
- ✔️ Automatic transmission shifting harshly or at the wrong times.
- ✔️ Intermittent stalling or difficulty starting the engine.
- ✔️ Complete failure to start, even with a good battery and starter.

Frequently Asked Questions
What exactly does the ECM do?
The Engine Control Module (ECM), or engine computer, is the brain of your vehicle’s engine. It controls critical functions like fuel injection timing, spark timing, idle speed, and emissions systems by reading data from dozens of sensors throughout the vehicle. A properly functioning ECM is essential for performance, fuel economy, and reliability.
Is this ECM ready to install when it arrives?
Yes! This is a key benefit of our service. We use the VIN you provide during checkout to program the module with the correct GM software for your specific vehicle. This makes it a true plug-and-play part, eliminating the need for additional programming by a dealer.
Where is the ECM located on a 2013-2016 Traverse?
On the 2013-2016 Chevrolet Traverse, as well as the related GMC Acadia and Buick Enclave, the ECM is typically located in the engine bay, mounted behind the engine’s cooling fan shroud. Always disconnect the vehicle’s battery before attempting removal or installation.
Why is providing my VIN so important?
Your Vehicle Identification Number (VIN) contains all the specific information about your car’s factory build, including the engine, transmission, and all equipped options. We use this data to load the exact software and calibrations your vehicle needs to run correctly. It also ensures compatibility with your vehicle’s security system.
Will this part fix my specific problem?
If your vehicle’s issues have been correctly diagnosed as a faulty ECM, then this part is the solution. The symptoms listed above are strong indicators of ECM failure. However, we always recommend a proper diagnosis by a qualified mechanic to rule out other potential causes like sensor or wiring problems.
Is this a new part?
No, this is a high-quality, tested, and fully functional used OEM part that has been sourced from a salvaged vehicle. This provides an excellent, cost-effective alternative to a brand new, expensive module from a dealership.
