Is your Chevrolet Trax, Cruze, or Sonic suffering from erratic behavior, a persistent Check Engine Light, or a no-start condition? The Engine Control Module (ECM), the vehicle’s central computer, is often the culprit. This genuine GM control module, part number 22819494, is the definitive solution to restore your vehicle’s performance, drivability, and fuel efficiency. It arrives at your door fully programmed with the latest GM software updates, specifically matched to your vehicle’s VIN. This eliminates the need for expensive dealership programming, making it a direct-fit, plug-and-play repair.
Common Symptoms of a Failing ECM
- ✔ Persistent Check Engine Light (CEL) with various trouble codes.
- ✔ Engine stalling, stumbling, or hesitating during acceleration.
- ✔ Complete no-start or intermittent starting issues.
- ✔ Noticeable decrease in fuel economy.
- ✔ Rough or unstable engine idle.
- ✔ Poor transmission shifting or performance issues that seem transmission-related.
- ✔ Failure to pass emissions testing.
The Importance of VIN Programming
Modern vehicles like your Trax have complex systems that are uniquely calibrated from the factory. The ECM controls everything from fuel injection and ignition timing to transmission shift points and emissions equipment. Simply installing a used or non-programmed module will not work; the vehicle’s anti-theft system will engage, and the engine will not run correctly, if at all. We take the guesswork and hassle out of the equation. By providing your Vehicle Identification Number (VIN) during checkout, our technicians will flash this module with the precise software for your vehicle’s specific configuration. This ensures seamless integration and immediate restoration of function right out of the box.
From the Diagnostic Bay
We had a 2014 Chevy Cruze come in with what the owner was convinced was a failing transmission. It was shifting hard and sometimes wouldn’t go into gear. They had already spent hundreds on a transmission fluid service with no improvement. After hooking up our scanner, we noticed communication errors with the TCM (Transmission Control Module), but the TCM itself checked out fine. The real issue was a failing ECM that was sending corrupt data across the CAN bus network, confusing the other modules. After installing a VIN-programmed ECM, all the shifting problems vanished. It’s a classic case of how a bad engine computer can create symptoms that point elsewhere, costing you time and money on the wrong repairs.
Your Direct-Fit 2013-2016 Trax ECM Solution
Before ordering, it’s always wise to have a qualified technician diagnose the issue. Ensure that all power and ground connections to your current ECM are clean and secure, as this can sometimes mimic module failure. However, if the diagnosis confirms a faulty computer, this part is your solution. This 2013-2016 Trax ECM is a reliable and cost-effective way to get your vehicle back to factory specifications. The installation is typically straightforward, involving disconnecting the battery, unplugging the electrical connectors, and unbolting the old module to replace it with this new one. In some cases, a simple security relearn procedure may be required, which can often be done without special tools.

Frequently Asked Questions
Do I need to take this ECM to a dealer for programming?
No. We handle all the programming for you before shipment. Simply provide your vehicle’s VIN when you place your order, and the module will arrive ready to install.
What happens if I install this without it being programmed to my VIN?
The vehicle will not start or run correctly. The anti-theft system will prevent the engine from starting, and the module will not be able to communicate properly with the other systems in your car. This is why providing your VIN is a required step.
Where is the ECM located on a 2013-2016 Chevy Trax?
The ECM on the Chevy Trax is typically located in the engine compartment, mounted to the side of the engine or on the firewall. It will have several large electrical connectors attached to it. Always consult a service manual for the exact location and removal procedure.
Is any special procedure needed after I install the new ECM?
In many cases, it is a simple plug-and-play installation. However, some GM vehicles may require a security relearn procedure, which can often be done at home by cycling the key in the ignition. We recommend searching for the specific relearn procedure for your model year.
How can I be sure my old ECM is the problem?
While the symptoms listed are strong indicators of ECM failure, a definitive diagnosis is always recommended. This involves checking for proper power and ground at the ECM connector and ruling out other potential causes like faulty sensors or wiring.
