Frequently Asked Questions
How do I provide my Vehicle Identification Number (VIN)?
After you complete your purchase, simply send us a message with your 17-digit VIN. We cannot ship your part until we receive this information, as the programming is specific to your exact vehicle.
Is any additional setup required after installation?
In most cases, you will need to perform a simple security relearn procedure, also known as a key relearn. This can typically be done in your driveway in about 30 minutes without any special tools and ensures the vehicle recognizes the new ECM. We can provide instructions for this procedure.
Will this fix my specific check engine light code?
This ECM is a direct solution for internal module failure codes like P0601 (Internal Control Module Memory Check Sum Error) or P0606 (ECM/PCM Processor Fault). If your code is for a specific sensor, you should diagnose that sensor first. However, a faulty ECM can sometimes cause false sensor codes.
How do I know if my original ECM is bad?
Besides the common symptoms listed above, the best way to confirm is with a professional diagnosis. However, if you have ruled out other components and are experiencing multiple, unrelated electronic issues or a specific internal processor fault code, the ECM is the most probable cause.
Does this part fit vehicles other than the 2014-2015 Spark?
Yes, absolutely. This is a very common GM module that fits a wide variety of vehicles, including many model years of the Cruze, Sonic, Trax, Encore, Volt, and even work vehicles like the Silverado and Express vans. Please check the detailed fitment list on this page to confirm compatibility.
