(incorporated within the door lock actuator) is
switched OFF, and then, because current flows to
the fuse, as well as to the door-control unit and the
lock timer, the lock timer causes base current to
flow to TrI for 0.5 second, thus switching ON Tr,. As
a result, current flows to the fuse, as well as to the
"lock" side coil of the door lock relay, Tr,, and to
ground, thus switching ON the "lock" side contacts
of the door lock relay and activating the door lock
actuators, thereby locking the doors.

When the doors are unlocked (by using the inside
lock knobs or the door key), the door lock switch
(incorporated within the door lock actuator) is
switched ON, and then, -because current flows to
the fuse, the door-control unit and the lock timer,
the lock timer causes base current to flow to Tr? for
0.5 second, thus switching ON Tr7. As a result,
