Choose whether your PCM requires a Vehicle Identification Number (VIN) update during service. A correct VIN ensures proper factory matching, eliminates security conflicts, and maintains compliance with dealer tools and inspections.
Choices
No VIN Change Needed — Select if the PCM already has your correct VIN.
VIN Change — We will program your PCM with your vehicle’s VIN for a seamless install and full compatibility.
Note: A valid VIN match is required for emissions testing, state inspections, and factory diagnostic functions. Always confirm your VIN selection before checkout.
