Cluster Variant Coding

As we have more options (SCC, VDC, EPB, Cubis, MDPS, TPMS. LDWS, ECS -) in the car, the dashboard now has more information to display depending on the chosen options.

For this reason, we need to learn which options the vehicle has when replacing 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.

2. Check point (Gauge)

2. Check point (Gauge) Diagnosis with Diagnostic Tool

Diagnosis with Diagnostic Tool

  1. In the body electrical system, failure can be quickly diagnosed by using the vehicle diagnostic system.
