Cluster Variant Coding

As we have more options (ESC, TPMS, SCC, etc.) in the car, the dashboard now have more information to display depending on the chosen options.

For this reason, we need to learn which options the current vehicle when we replace the dashboard.

To address this issue, a course of learning based on the option required for the vehicle when replacing the dashboard should be carried out.

This is called Variant Coding.
