  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.

  3. To consult the present input/output value of BCM, "Current DATA". It provides information of BCM input/output conditions of power supply, turn signal/brake lamp, headlamp, door, locks, outside mirror, wiper, auto-light and transmitters etc.
