When the door lock switch is set to the LOCKside (or UNLOCK side), the LOCK side (or
UNLOCK side) of the door lock relay is turned
ON and the door actuators of all doors operate.l

With the driver’s and front passenger’s doorsunlocked, press the LOCK switch of the
transmitter, and the door lock signal output (0V) will be sent from the
keyless entry control
unit terminal No. 12 closing the door lock powerrelays 1 and 2 to lock the driver’s and front
passenger’s doors.
While the R.H. and L.H. doors are in the lockedstate, press the UNLOCK switch of the
transmitter once, and the DOOR UNLOCK
switch signal (0 V) will be sent from the keylessentry control unit terminal No. 14 closing the
door lock power relay 2 to unlock the driver’s
door.
Under the above-mentioned conditions, further
press the UNLOCK switch of the transmitter,and the DOOR UNLOCK signal output (0 V)
will be sent from the keyless entry control unitterminal No. 13 closing the door lock power
relay 1 to lock the front passenger’s door.
When the keyless entry system is operated toturn the driver’s door lock switch from the
UNLOCK position to the LOCK position, thelock knob) is locked with the key inserted in
the ignition switch, the ETACS unit grounds the
unlock side circuit of the door lock relay to unlock
all doors. This way, failure to remove the key
is prevented.dome light/foot light blinking signal output
(system voltage) will be sent twice from the
keyless entry control unit terminal No. 11 when
the door lock switch is turned from the LOCK
position to the UNLOCK position, the lighting
signal output (0 V) will be provided for approx.
3 seconds.
NOTE
The dome light winks or comes on when the domelight switch is in the DOOR interlock position.
However, the dome light does not wink while it .is
ON for 6 seconds after closing the door by ETACS
function.Besides the above-mentioned operations, the
keyless entry control unit has the following functions.l
If any door is not opened or closed within 30
seconds from unlocking the door by means ofthe
keyless entry system, the door is
automatically locked.In addition, if the
cryptographic code other than the code storedin the receiver memory is received 30 times
in one minute continuously, operation of the
unit is suspended for 10 minutes.l
Operation is also suspended if the ignition key
remains inserted (key reminder switch: OFF)
and either door is left open (door switch: ON).TROUBLESHOOTING HINTS

the ground wire for connection.
l Only R.H. or L.H. door can be locked or
unlocked.
1)Check the door lock power relay 1 (for front
passenger’s door) or door lock power relay2 (for driver’s door). (Refer to GROUP
