This is a Toyota Tundra 2019 model. Here we will show how to correct mileage with CG100X programmer.
Original mileage: 199,494miles
This is the instrument cluster. The processor type is S6J32CSK but there is an RH chip over there. It is the RH66 chip that stores the mileage data.
CG100X does not support S6J32CSK processor so we try to read RH chip and see if it is working.
This is a microchip. Take this eeprom RH chip off. We are going to read the eeprom with CG100X and correct mileage.
Desolder RH66 chip to eeprom adapter.
Connect adapter with cg100x
In CG100X software, we go to Serial>>RHXX>>RH66
Then we click on Read then read eeprom.
Back up the data if anything corrupt you can rewrite the backup.
Save data.
CG100X does not have Tundra 2019 option. We use Toyota Alphard option.
Go to Dashboard>>Asian Car>>Toyota>>Alphard>>RH66
Read data.
CG100X detects original mileage which is correct.
Enter the new KM you desired.
Mileage correction is completed.
Save new mileage data.
Solder chip back to cluster.
Check new mileage on dashboard.
Done.
