  1. The body control module can diagnose by using the GDS more quickly. The BCM communicates with the GDS and then reads the input/output value and drives the actuator.
  2. To diagnose the BCM function, select the menu of model and body control module.
  3. Select "Input/output monitoring", if you will check current data of body network system. It provides input/output status of each module. BCM service data, CLU service data, SJB service data
  4. If you will check each module data operation forcefully, select "Actuation test".
  5. If you want to change user option, select "user option".
