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.
To diagnose the BCM function, select the menu of model and body control module.
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.
