HARNESS CONNECTOR INSPECTION
CONNECTOR CONTINUITY AND VOLTAGE TESTWhen checking continuity and/or voltage at the waterproof
connectors, follow the steps below to avoid poor connector
contact and/or reduced waterproof performance of connectors.
(1) When checking is performed with the circuit in the stateof continuity, be sure to use the special tool (harness
connector).
Never insert a test bar from the harness side, because
to do so will reduce the waterproof performance and result
in corrosion.
(2) When the connector
JS disconnected for checking the fe-
male pin, the harness for checking the contact pressureof connector pins should be used.
Never force the insertion of a test bar, because to do
so will cause poor contact.(3) When the male pin is to be checked, apply the test bar
against the pin directly.
Care must be taken not to short-circuit the connector pins.
TERMINAL ENGAGEMENT CHECK
When the terminal stopper of connector is out of order, engage-
ment of male and female terminals becomes improper even
when the connector itself is engaged perfectly and the terminal
sometimes slips out to the rear side of connector. Ascertain,
therefore, that each terminal does not come off the connector
by pulling each harness wire.
CONNECTOR TERMINAL ENGAGEMENT AND
DISENGAGEMENTConnectors which are loose shall be rectified by removing
the female terminal from connector housing and raising its
lance to establish a more secure engagement. Removal of
connector terminal used for MFI and 4 A/l control circuit shallbe done in the following manner.
COMPUTER CONNECTOR(1) Insert screwdriver
[1.4 mm (.06 in.) width] as shown in
the figure, disengage front holder and remove it.

lBattery positive voltage is continuously applied to the key-reminder switch.l
If the driver’s door is opened (door switch ON) with the key inserted in the ignition switch (key-reminderswitch ON), the buzzer sounds to warn that the key has been left in the switch.
&eat belt warning>
lWhen the ignition switch is turned on, the timer circuit and pulse circuit will flicker the seat belt warning
light for approx. 6 seconds with the buzzer intermittently sounding.
lIf the seat belt is fastened for the while, the seat belt switch will be turned off and the buzzer will
stop.

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
