* For cars before 15 years, you need to add a filter. After that, you can operate steps 4(OBD read kilometers)and steps 5(OBD write kilometers);
* For cars after 17 years do not support Odometer Correction temporarily.
Take the calibration process of Benz W205 chassis instrument for 16 years as an example:
Main step:
* OBD reads configuration information
* The MCU edits the data
* Write configuration information
* You can adjust the mileage
Let us go through them one by one:
1.OBD reads configuration information
Please remember to save Configuration data after successful reading!
2.The MCU edits the data
At this time, you need to remove the back cover of the dashboard, select the type, and select the wiring method according to the type.
You can open the wiring diagram directly. There are 5 wires in total(as the picture). The Dashboard is divided into 8 drives and 11 drives.

* select the saved data at this time.
* you can get the prompt that the vehicle configuration information is written successfully
4. You can adjust the mileage
Read the kilometers first, and then write the kilometers
