Is your Chevrolet Cruze, Sonic, or other GM vehicle suffering from perplexing engine problems? A faulty Engine Control Module (ECM) is often the culprit behind issues like a persistent check engine light, poor performance, and even a no-start condition. As the central computer for your engine, the ECM’s health is critical for performance, fuel economy, and emissions. This direct-fit replacement ECM, part number 22819494, is the definitive solution to restore your vehicle’s factory operation.
Unlike generic modules that require expensive dealership programming, this unit arrives at your door fully programmed to your specific vehicle. We use your Vehicle Identification Number (VIN) to load the latest, most stable GM-certified software, ensuring seamless communication with all your vehicle’s systems. This plug-and-play solution eliminates the need for special tools or costly trips to a mechanic, getting you back on the road quickly and confidently.
From the Diagnostic Bay
We had a 2014 Chevy Cruze come into the shop with a classic case of what the owner called ‘automotive gremlins.’ The car would randomly stall at red lights, the check engine light would flash intermittently with a slew of unrelated codes (from O2 sensors to transmission communication errors), and fuel economy had plummeted. The owner had already replaced two sensors with no improvement. We suspected the ECM. After connecting our diagnostic tool, we found the ECM was failing to maintain stable communication. We installed one of our VIN-programmed modules, performed the quick security relearn, and the car ran perfectly. All the ghost codes vanished, and the stalling issue was completely resolved. It’s a prime example of how a failing ECM can mimic many other problems, making a reliable, correctly programmed replacement essential.
Your Pre-Programmed 2012-2016 Cruze Engine Control Module
The ECM is the brain of your vehicle’s powertrain, managing everything from the air-fuel mixture and ignition timing to transmission shift points and emissions equipment. When it begins to fail, the symptoms can be widespread and confusing. Replacing it with a properly configured unit is the only way to ensure a lasting repair. Our process is simple: you provide your VIN during checkout, and our technicians flash the module with the precise software for your car’s make, model, year, and options. This ensures that anti-theft systems, engine parameters, and all other vehicle-specific settings are correct right out of the box.
Common Symptoms of a Failing ECM
- ✔ Persistent Check Engine Light (CEL) that won’t clear.
- ✔ Engine misfiring, stumbling, or running rough.
- ✔ Unexplained drop in fuel efficiency.
- ✔ Vehicle cranks but refuses to start.
- ✔ Automatic transmission shifting erratically or harshly.
- ✔ Loss of power and poor acceleration.
- ✔ Failure to pass state emissions inspection.

Frequently Asked Questions
Do I need to have this module programmed by a dealer?
No. We handle all the programming for you before shipment. Simply provide us with your vehicle’s VIN, and the module will arrive ready for installation.
How do I provide my VIN?
You can add your VIN in the notes section during checkout or reply to your order confirmation email with the information. We cannot ship your part until we receive the VIN.
Is this part truly ‘plug and play’?
Yes, for most vehicles. After installation, you may need to perform a simple security relearn procedure, which takes about 30 minutes and does not require any special tools. We provide easy-to-follow instructions for this process.
What causes an ECM to fail?
ECM failure can be caused by several factors, including electrical shorts, voltage overloads from a bad alternator or jump-start, excessive heat and vibration over time, and internal component degradation.
Will this fix my ‘No Communication with ECM’ error code?
In many cases, yes. A ‘No Communication’ code (like U0100) is a strong indicator that the ECM itself has failed. This programmed module is designed to resolve that communication link and restore proper function.
