Door locking or unlocking by operating the driver’s or
front passenger’s door lock switch
When the door is locked by the driver’s or front passenger’s
door lock switch, the ETACS-ECU operates its door lock relay
and passes a current through the door lock actuators of all
doors for 0.25 seconds to lock all doors.
When the door is unlocked by the driver’s or front passenger's
door lock switch, the ETACS-ECU operates its door unlock
relay and passes a current through the door lock actuators of
all doors for 0.25 seconds to unlock all doors.
When the door is locked and unlocked by driver’s or front pas-
senger's door lock switch consecutively, the ETACS-ECU oper-
ates its door lock relay and passes a current through the door
lock actuators of all doors for 0.25 seconds to lock all doors.
Then, the ETACS-ECU operates its door unlock relay and
passes a current through the door lock actuators of all doors for
0.25 seconds to unlock all doors. Due to this, there may be a
time lag between the driver’s or front passenger's door lock
switch actuation and the time when all doors is unlocked.
