Frequently Asked Questions
Do I need to do any programming after I install this?

Where do I provide my VIN?
After you complete your purchase, you will need to send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship the part until we receive this information, as it is required for programming.

Will this fix my car’s specific problem?
This ECM will fix any issue directly caused by a faulty engine computer. While it resolves the most common electronic problems, including specific DTC codes, we always recommend having a qualified mechanic properly diagnose your vehicle to confirm the ECM is the point of failure before ordering.
