Restore Peak Performance to Your GM Vehicle
Is your Chevrolet, Buick, or GMC suffering from frustrating and unpredictable issues like stalling, a persistent Check Engine Light, rough idling, or poor fuel economy? These are classic signs of a failing Engine Control Module (ECM), the central computer that manages your engine’s performance. A faulty ECM can make your vehicle unreliable and unsafe. This isn’t just an inconvenience; it’s a critical component failure that needs a dependable solution.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We provide a genuine OEM quality **2012-2016 Sonic Engine Control Module** that comes professionally programmed with the latest GM-certified software updates. All we need is your vehicle’s VIN at checkout. This crucial step ensures that the module communicates flawlessly with your specific vehicle’s systems, restoring its original drivability and efficiency without a costly trip to the dealership for programming.
Case Study: A Tricky Diagnosis
A customer brought in a 2014 Chevy Sonic with a complaint that stumped two other shops: intermittent stalling at stoplights with no consistent trouble codes. After a thorough diagnostic, we noticed a slight delay in sensor data reporting through our scan tool. Experience pointed towards the ECM’s processor struggling under load. We installed one of these pre-programmed modules, and the problem vanished instantly. The latest software update included in our programming process resolved a known logic flaw that caused this exact symptom. The customer was back on the road in an afternoon, avoiding weeks of guesswork.
Is Your Vehicle Exhibiting These ECM Failure Signs?
- ✔ Check Engine Light is on, often with codes like P0601, P0606, or U0100.
- ✔ The engine cranks but refuses to start.
- ✔ Unexplained drops in fuel mileage.
- ✔ The vehicle stalls unexpectedly while driving or at idle.
- ✔ Hesitation or stumbling during acceleration.
- ✔ Automatic transmission shifting erratically or harshly.

A Straightforward Guide to Installation
Installing your new **2012-2016 Sonic Engine Control Module** is a direct process that a confident DIYer or any professional mechanic can handle. Since the module arrives programmed, no special scan tools are needed for the initial setup.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait 10-15 minutes for the system capacitors to discharge.
- Locate the ECM: On most compatible vehicles, the ECM is found in the engine bay. Its exact location can vary, so consult a service manual for your specific model if you’re unsure.
- Disconnect Connectors: Carefully release the locking tabs on the electrical wiring harnesses and pull them straight out from the module. Do not force them. Inspect the connectors for any corrosion or bent pins.
- Remove the Old Module: Unbolt the old ECM from its mounting bracket. Keep the hardware as you will reuse it.
- Install the New Module: Mount your new, pre-programmed ECM onto the bracket and secure it with the original hardware.
- Reconnect Everything: Firmly plug the wiring harnesses back into the new module until they click into place. Reconnect the negative battery terminal.
- Final Steps: Depending on your vehicle, a security relearn procedure may be required. This can typically be done by cycling the key and takes only a few minutes. Your vehicle is now ready to start.

Do I need to do any additional programming after installation?
Do I need to do any additional programming after installation?
No. We program the module to your vehicle’s VIN before shipping. In most cases, it’s a plug-and-play installation. Some vehicles may require a simple security relearn procedure, which can be done without any special tools by cycling the ignition key.
What is a VIN and why do you need it?
The VIN (Vehicle Identification Number) is a unique 17-digit code for your specific car. We use it to load the exact factory software and calibrations for your vehicle’s engine, transmission, and options, ensuring perfect compatibility and performance.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the ECM (common codes P0601-P0606), then yes, this part will resolve the issue. However, if the light is on for another reason (e.g., a bad oxygen sensor), that separate issue will still need to be addressed.
Is this a used part?
This is a high-quality, OEM-grade replacement part that has been thoroughly inspected and tested to meet or exceed original specifications. It is programmed with the latest software from GM, providing a reliable and long-lasting repair.
How do I find my original part number?
The part number is printed on a sticker on your original ECM. However, you don’t need to match it exactly. As long as your vehicle is on our compatibility list, we will program the correct software for you using your VIN.
