Frequently Asked Questions
What is VIN programming and why do I need it?
VIN programming is the process of loading your vehicle’s unique 17-digit Vehicle Identification Number and specific software onto the ECM. This ensures the computer works correctly with your vehicle’s engine, transmission, and other electronic systems. It is essential for proper function and to prevent anti-theft or compatibility issues.
Is this ECM ready to install when it arrives?
Yes, this ECM is shipped to you pre-programmed for your vehicle. For many applications, it is a direct installation. However, some vehicles may require an additional security relearn or crankshaft position sensor relearn procedure, which can often be done without specialized tools. Please consult your vehicle’s service manual.
How do I provide my VIN?
After you complete your purchase, you will need to send us your vehicle’s 17-digit VIN. You can typically add this as a note during checkout or send it to us in a message referencing your order number. We cannot ship the part until we receive your VIN.
My original part number is different. Will this still work?
Yes. This ECM, part number 12622175, is the designated service replacement for a wide range of earlier part numbers, including 12636659, 12639300, 12628993, and others listed in the description. As long as your vehicle is listed in the compatibility chart, this module will function correctly.
Will this fix my specific check engine light codes?
A programmed 12622175 ECM is the direct solution for fault codes related to the internal processor, memory, or driver circuits of the module itself. While it can resolve many performance-related issues, it’s crucial to ensure that any codes for external sensors or wiring have been properly diagnosed and addressed first.
