It will be able to diagnose defects of BCM with scan tool quickly. Scan tool can operates actuator forcefully, input/output value monitoring and self diagnosis.
Select model and menu.
Select "Current data", if you will check current data of BCM. It provides power supply status, multi function status, lamp status, door status, lock system status, wiper, auto light status and so on.
If you will check BCM data operation forcefully, select "Actuation test".
You can turn ON/OFF as below option function with the user option program.
