Is Your Traverse Running Unreliably? Get Back on the Road with Confidence.
There’s nothing more stressful than a family vehicle you can’t trust. If your 2013-2016 Chevrolet Traverse is suffering from a persistent check engine light, poor performance, intermittent stalling, or a complete no-start condition, a failing Engine Control Module (ECM) is often the root cause. This isn’t just an inconvenience; it’s a matter of safety and reliability. Instead of facing a costly and complicated repair at the dealership, we offer a direct, dependable solution to get your SUV running smoothly again.
Common Symptoms of a Failing ECM & Your Direct Solution
A faulty engine computer can cause a wide range of confusing issues that are often misdiagnosed. If you’re experiencing any of the following, this module is the solution you need:
- Persistent Check Engine Light (CEL) with communication-related codes (e.g., U0100)
- Internal processor failure codes like P0601, P0603, or P0606
- Unexplained engine misfires, stumbling, or hesitation
- Drastic decrease in fuel economy
- Transmission shifting problems or harsh engagement
- Vehicle won’t start, even with a good battery and starter
This replacement 2013-2016 Traverse programmed ECM arrives ready to install, taking the guesswork and extra expense out of the repair. We handle the complex programming so you can focus on the simple installation.
An Expert’s Note: We recently helped a family whose 2015 Acadia (which uses this same ECM) was stalling randomly at stoplights. They had already replaced the battery and alternator with no success. The issue was a classic ECM failure causing inconsistent fuel injector commands. Once they installed our pre-programmed module, the problem was solved instantly. Don’t waste time and money chasing parts—the ECM is the brain of your engine, and when it fails, a direct replacement is the only reliable fix.

Frequently Asked Questions
Do I need to do any programming myself?
No. This ECM comes fully programmed to the VIN you provide during checkout. The only thing you may need to do is a simple security relearn procedure (also known as a CASE relearn), which can be done without any special tools and takes about 15-30 minutes. We include instructions for this process.
What information do you need from me?
After you place your order, you must provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). This is essential for us to load the correct software and operating system for your specific vehicle configuration.
Is this a new part?
No, this is a high-quality, tested used part that has been sourced from a salvaged vehicle. Each unit is inspected and verified to be fully functional before being programmed and shipped.
Will this fit models other than the Traverse?
Yes. This ECM, identified by part numbers like 12633555 and 12653998, fits a wide range of GM vehicles including the Acadia, Enclave, Malibu, Impala, and many others. Please check the detailed fitment list on this page to confirm compatibility with your specific make, model, and year.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of your original ECM (like codes P0601 or P0606), then this part will solve the problem. However, if the light is on for another reason (e.g., a bad oxygen sensor), you will still need to repair that underlying issue. This module will fix all problems directly related to the computer itself.
