Product Description – OBD VIN Correction Filter


During vehicle inspection, testing, or ownership transfer, the system reads the VIN (Vehicle Identification Number / Chassis Number) through the OBD port to verify vehicle compliance.

If the VIN read from the diagnostic system does not match the vehicle nameplate, the inspection or registration process may fail.


This issue often occurs after vehicle maintenance or refurbishment, especially when control modules or ECU units are replaced.


To solve this efficiently, we developed this OBD VIN Correction Filter, also commonly known as:


VIN Emulator


VIN Filter


VIN Repair Module


OBD VIN Programmer


Chassis Number Correction Device



Why Choose This VIN Correction Device
