Here we have a Toyota Corolla 2017 Instrument.
We change the KM using Iprog and CGDI CG100X without problems.
We solder cables to read eeporm data first.
Original odometer.
Write KM but don’t work.
The KM is not stored in the processor but in the eeprom 93C66.
So we desolder 93c66 chip and solder it on CG100X eeprom adapter.
Read eeprom again.
Enter new km and write it into chip.
Solder back 93c66 chip and KM changed no problem
Done! Simple and nice!
