Is Your GM Vehicle Running Rough or Not Starting?
If you’re dealing with a persistent check engine light, erratic engine behavior, stalling, or a complete no-start condition, a failing Engine Control Module (ECM) is a likely culprit. As a technician with over two decades of experience under the hood, I’ve seen how a faulty ECM can turn a reliable vehicle into a source of constant frustration. Itโs the central computer for your engine, and when it goes, everything from fuel economy to shifting can be affected. This isn’t just an inconvenience; it’s a critical failure that needs a reliable solution.
The Direct Solution: A Pre-Programmed 2017-2020 Trax ECM
Forget expensive dealership visits and the hassle of finding a shop that can program a new module. We offer a straightforward, effective solution. This genuine GM ECM, compatible with part numbers 12668986 and 12692201, arrives at your door programmed specifically for your vehicle. We use your Vehicle Identification Number (VIN) to load the latest, most stable software updates directly from GM. This ensures your vehicle operates exactly as the manufacturer intended, restoring performance, reliability, and fuel efficiency.
Real-World Diagnostics: A Technician’s Story
“A customer’s 2018 Chevy Sonic came into my shop last month with an intermittent no-start and a P0606 (ECM Processor Fault) code that would come and go. They had already replaced the battery and checked the main grounds. After confirming power and ground at the ECM connector were solid, we suspected the module itself. These Ecotec platform ECMs can develop internal communication faults that mimic wiring problems. We installed one of our VIN-programmed modules, performed the security relearn, and the car fired up instantly. The code never returned. Itโs a classic case where chasing wires would have wasted hours, but replacing the core component provided a quick, permanent fix.”

Simple Installation Process
While professional installation is always recommended, here is a general guide to replacing your ECM. Always consult a vehicle-specific service manual.
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait at least 10 minutes to allow capacitors to discharge.
- Locate the ECM: On most listed models, the ECM is found in the engine compartment, often on the driver’s side.
- Disconnect Connectors: Carefully release the locking tabs on the electrical connectors and pull them straight out. Never force them. Inspect the pins for any corrosion or damage.
- Remove the Old Module: Unbolt the old ECM from its mounting bracket and remove it from the vehicle.
- Install the New Module: Bolt your new, pre-programmed ECM into place. Reconnect the electrical connectors, ensuring they click securely into position.
- Reconnect Battery: Reattach the negative battery terminal.
- Perform Security Relearn: You will need to perform a simple key-relearn procedure (often called a “security relearn” or “anti-theft relearn”) to sync the new ECM with your vehicle’s keys. This procedure typically takes 10-30 minutes and can be done without special tools. Instructions are widely available online for your specific model.
