  4. User Setting Mode (USM)

    Setting can be changed by using switches (Menu, UP, Down and OK button). There are many parts (for example, In/Out Seat Synchronization, In/Out Steering Wheel Synchronization, Auto Door Lock, Auto Door Lock Deactivate, Head Lamp Escort, Welcome Light, Welcome Sound, One Touch Turn Signal, Average Fuel Consumption Auto Reset, Brightness, and Content Setup) that can be set and customized. The signal flow during setting is as follows.

    1. UMS settings are set, they are transmitted to BCM.
    2. BCM transmits the settings via B_CAN to the relevant modules.
    3. The module completes setting and transmits the modified setting to BCM.
    4. BCM transmits the final settings via C_CAN to the cluster.

      Information 

      The cluster communicates directly with C-CAN units.
