When door lock and unlock switch is turned to LOCK
When door lock and unlock switch is turned to UNLOCK
Without CONSULT-II
1. Remove key from ignition switch, and the door of driver side and passenger side is closed.
2. Check the signal between BCM connector and ground with oscilloscope when door lock and unlock
switch (front LH and front RH) is turned “LOCK” or “UNLOCK”.
