OPERATION
BUZZER
Light Reminder Warning Buzzer Function
When the driver’s door is opened with lighting switch
in the ON (tail lamp switch or headlamp switch)
position and ignition switch in the LOCK (OFF) or
ACC position, the buzzer will sound continuously to
remind the driver that the lamps (tail lamps or
headlamps) are ON.
This function does not work if the lighting switched
off through the headlamp automatic shutdownfunction. In addition, the ignition key reminder
warning buzzer function has a priority over this
function.
Center Display Operation Annunciation
Function
On vehicles with center display, the buzzer (peeps)
sounds when the operation switch of the audio
and navigation system is pressed.
CENTRAL DOOR LOCKING SYSTEM
Central Door Locking System Operation
When the lock switch is turned ON after the unlock
switch on the driver’s door lock actuator switch
is OFF, the ETACS-ECU gives a lock output for
0.5 second. When the unlock switch is turned ON
after the lock switch on the driver’s door lock
actuator switch is OFF, the ETACS-ECU gives an
unlock output for 0.5 second.
When the front passenger’s door key or back door
key is operated, the ETACS-ECU gives a lock or
unlock output for 0.5 second.Forgotten Key Prevention Function
If, with the key reminder switch OFF and the driver’s
door switch ON, the driver’s door lock switch is
turned ON after the door unlock switch in the front
door lock actuator is turned OFF, the ETACS-ECU
waits 0.3 second then give an unlock relay output
for 0.5 second, there by preventing the doors from
being locked. This operation prevents the ignition
key from being locked inside the vehicle. This
function takes precedence over the central door
locking control function.
