Settings are sent via BCM B_CAN to the relevant module >
When the module setting is completed, the current settings are sent to BCM >
The final settings are sent via BCM C-CAN to the dashboard.
B.
HUD(Head Up Display) setting
HUD-related settings of UMS are sent >
HUD light brightness/height settings are sent to display the final setti ngs
C.
Haptic setting : The haptic settings of UMS are transmitted to modify the haptic experience.
Diagnosis with GDS

It will be able to diagnose defects of CLU with GDS quickly. GDS can operates actuator forcefully, input/output value monitoring and self diagnosis.
2.
Select model and "BCM".
3.
Select the "Cluster Moduel" to check.
4.
Select "Input/output monitoring", if you will check current data of instrument cluster.
5.
If you will check each module data operation forcefully, select "Actuation test".

6.
To check the DTC of the each module, select "DIAGNOSTIC TROUBLE CODES".
