Script for mileage correction in dashboards of 2021 Kia Rio cars from Continental made on the Renesas (NEC) 70F3524 microcontroller.

I'll tell you a little about these panels. In principle, these dashboards are no different from the panels of previous years, except that the manufacturer has disabled EEPROM recording if the mileage is more than 100 km. That is, if the mileage on the display is from 0 to 100 km, then EEPROM recording works, if more than 100 km, the panel responds with an error that such a command (EEPROM recording) is not supported.

This script allows you to bypass this problem. The script works completely via OBD2. It may also support other 2021 Kia / Hyundai models with NEC70F3524.
