    2. UMS Setting Procedure
      1. Module setting

        (1) UMS settings are sent to BCM →

        (2) Settings are sent via BCM B_CAN to the relevant module →

        (3) When the module setting is completed, the current settings are sent to BCM →

        (4) The final settings are sent via BCM C-CAN to the dashboard.

      2. HUD (Head Up Display) setting

        (5) HUD-related settings of UMS are sent →

        (6) HUD light brightness/height settings are sent to display the final settings

      3. Haptic setting: The haptic settings of UMS are transmitted to modify the haptic experience.
