Is Your Chevy Trax Running Rough? The ECM Might Be the Culprit.
The Engine Control Module (ECM), often called the vehicle’s main computer, is the brain behind your engine’s performance, fuel economy, and emissions. When it starts to fail in your 2013-2016 Chevrolet Trax, it can cause a cascade of confusing and frustrating problems. From a persistent check engine light to a vehicle that won’t start at all, a faulty ECM can bring your daily drive to a halt. This genuine GM Engine Control Module, part number 12692200, is the definitive solution to restore your vehicle’s factory performance and reliability.
From the Diagnostic Bay
We had a 2015 Chevy Trax come in with a complaint of intermittent stalling at stoplights and a check engine light that would come and go. The owner had already replaced the spark plugs and an ignition coil with no luck. Our scan tool showed a U0100 ‘Lost Communication with ECM’ code, but only intermittently. After checking all the wiring and grounds, we suspected an internal failure in the ECM. Instead of a costly and time-consuming diagnostic process at the dealer, we installed a VIN-programmed module like this one. The new ECM immediately resolved the communication errors and the stalling. The customer was back on the road the same day, saving hundreds in diagnostic fees and dealership programming costs.
Symptoms of a Failing 2013-2016 Trax ECM
- ✔ Check Engine Light is on with various, often inconsistent, trouble codes.
- ✔ Engine cranks but refuses to start.
- ✔ Rough idling, stalling, or hesitation during acceleration.
- ✔ Noticeable decrease in fuel efficiency.
- ✔ Transmission shifting issues or harsh shifts.
- ✔ Misfire codes (like P0300) that don’t resolve after replacing plugs or coils.
- ✔ Loss of communication with the scan tool or other modules.
