4. User Setting Mode (USM)

   Setting can be changed by using switches (Menu, UP, Down and OK button). There are many items (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. After setting, UMS settings 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.
