Script for mileage correction in Continental instrument clusters of Ford cars made on UNPROTECTED Renesas R7F701402, R7F701403, R7F701405 microcontrollers.

The script supports reading/writing mileage, reading/writing EEPROM (CAN-BUS), as well as FLASH patching and FLASH recovery from a previously read backup (UART). In these instrument clusters, writing to some EEPROM cells is blocked. To unlock EEPROM writing, a FLASH patch via UART is required. After the patch, EEPROM writing is unlocked and, accordingly, mileage writing too.

The script works via the OBD2 adapter (CAN-BUS). Approximate list of cars: Escape, Fiesta, Focus 4, Transit, Kuga, Ecosport.
