DOOR LOCK FUNCTION
 The door lock and unlock switch (driver side) are build into power window main switch.
 Interlocked with the locking operation of door lock and unlock switch, door lock actuators of all doors are
locked.
 Interlocked with the unlocking operation of door lock and unlock switch, door lock actuators of all doors and
are unlocked.
 When ignition switch is ON and BCM receives air bag deployment signal, it operates automatically to unlock
all doors. Air bag diagnosis sensor unit sends the air bag deployment signal to BCM.
Door Key Cylinder
 With the door key inserted in the door key cylinder on driver side, turning the door key cylinder to “LOCK”,
locks door lock actuator of driver side door.
 With the door key inserted in the door key cylinder on driver side, turning the door key cylinder to “UNLOCK”,
unlocks door lock actuator of driver side door.
