Script for mileage correction in Continental Haval H6 Coupe dashboards made on the Renesas 70F3529 microcontroller. The script supports reading/writing the microcontroller's EEPROM and has a built-in mileage calculator. The script works via the OBD2 (CAN-BUS) diagnostic connector of the car or on the table (the connection is available in the pdf help file).
