Restore Peak Performance to Your GM Vehicle
Is your Chevrolet Cruze, Sonic, or other GM vehicle acting up? If you’re dealing with frustrating issues like a persistent check engine light, stalling, rough idling, or a no-start condition, a failing Engine Control Module (ECM) is often the culprit. As a technician with over two decades of experience, I’ve seen how a faulty ECM can cause a cascade of confusing problems. This isn’t just an inconvenience; it affects your vehicle’s reliability, fuel economy, and safety. This replacement Engine Control Module, part number 22819494, is the definitive solution to get your car running smoothly again.
The biggest headache with replacing an ECM has always been the expensive and time-consuming programming required at a dealership. We eliminate that step completely. Before this module ships, we will program it with the latest official GM software, specifically matched to your vehicle using the VIN you provide. This means it arrives at your door ready for installation, saving you hundreds of dollars in dealer fees and getting you back on the road faster. This is the most direct path to fixing complex electronic issues and restoring your vehicle’s factory-specified performance.
A Technician’s Notebook: The Intermittent Gremlin
I remember a 2014 Cruze that came into my bay with a list of intermittent symptoms that had stumped two other shops. The owner reported random stalling at red lights, occasional hard starting, and a check engine light that would come and go. The codes were all over the place—communication errors, random sensor faults. After verifying the wiring harness and grounds were solid, my experience pointed to the ECM itself. The internal processor was likely failing under certain temperature conditions. We installed a VIN-programmed module just like this one, and the car ran perfectly. The customer was thrilled to have a reliable car again after weeks of uncertainty. This is why a quality, correctly programmed 2012-2016 Cruze ECM is so critical.
Is Your Vehicle Showing These Signs?
A failing ECM can manifest in many ways. If you’re experiencing any of the following, it’s time to consider a replacement:
- âś” Persistent Check Engine Light (CEL)
- âś” Engine stalling or shutting off while driving
- âś” No-start or hard-start conditions
- âś” Poor or erratic engine performance and acceleration
- âś” Decreased fuel economy
- âś” Communication error codes, such as U0100
- âś” Internal module fault codes, like P0601 or P0606
- âś” Issues with automatic transmission shifting
A Straightforward Guide to Installation
Installing your new 2012-2016 Cruze ECM is a manageable job for a DIY enthusiast. Follow these steps carefully for a successful replacement.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes to ensure the system is fully discharged.
- Locate the ECM: On most compatible vehicles like the Cruze or Sonic, the ECM is located in the engine bay, often near the battery or firewall. It’s a metal box with several large electrical connectors.
- Disconnect and Remove: Carefully unclip and remove the electrical connectors. Note their orientation. Then, unbolt the mounting hardware holding the old ECM in place and remove it from the vehicle.
- Install the New Module: Mount the new, pre-programmed ECM in the same location. Secure it with the original hardware.
- Reconnect Everything: Firmly plug the electrical connectors back into the new ECM. Reconnect the negative battery terminal.
- Final Steps: In some cases, a security or crank position sensor relearn procedure may be required. This can often be done without special tools. Start the vehicle and let it idle for 5-10 minutes to allow the system to adapt.

Do I need to do anything after installing the ECM?
After installation, you should start the car and let it idle for a few minutes. Some vehicles may require a simple security relearn or crankshaft position sensor relearn procedure, which can typically be done without special scan tools. Instructions are widely available online for specific models.
