Frequently Asked Questions
What do I need to do after I purchase?
After you complete your purchase, you must provide us with your vehicle’s 17-digit VIN (Vehicle Identification Number). We need this to load the correct, updated software for your specific car before we can ship the part to you.
Is this part difficult to install?
The physical installation is typically straightforward for someone with mechanical experience, as it involves disconnecting the battery and swapping the module. However, some vehicles may require a security or anti-theft relearn procedure, which can be done with a capable scan tool. We always recommend professional installation if you are not comfortable with automotive electronics.
Is this a new part?
No, this is a high-quality, used OEM part sourced from a salvaged vehicle. Each unit is thoroughly inspected and tested to ensure it is fully functional before being programmed and shipped.
Will this fix my car’s specific problem?
This programmed 2013-2016 Buick Verano ECM will correct issues directly caused by a faulty control module. It is crucial that your vehicle has been properly diagnosed by a qualified technician to confirm the ECM is the point of failure. This part will not fix problems related to bad wiring, faulty sensors, or other mechanical issues.
What does “plug and play” mean?
“Plug and Play” means the unit arrives ready to be installed without the need for additional programming by a dealer. Because we flash it with your car’s VIN and the latest software, it will communicate correctly with your vehicle’s other systems upon installation.
