INHIBITOR SWITCH The inhibitor switch’s ON (when “N” or
“P”) or OFF (when
other than “N” or
“P”) signals are input to the engine control
unit. The engine control unit, based on these signals, then
determines whether the transaxle is in neutral or is in a drive
range, and then activates the idle-speed control servo so as tc
regulate the idling rpm.

CONTROL RELAY (Fuel pump drive signal)
This relay senses that power is supplied to the pump.
-If power failed to be supplied to the fuel pump during
er,, .ecranking or during driving, the engine control unit judges that a
fault has occurred and stores corresponding diagnosis code
(No. 42) in memory and at the
sa’me time, causes the engine
alarm lamp (Mulfunction indicator lamp) to come on.IGNITION

rhis switch sends a High signal to the control unit when the ignition ‘ncorporated within the key cylinder.
“ON” signals are sent to the control unit by switch A while the key is
inserted in the key cylinder; “ON” signals are sent by switch
Bwhen the key is not in the key cylinder.

OPERATlON
Belt Fastening Motion
(1) If the belt is not in the fastening position (the
L.H. or R.H. door latch switch at Door Closed
position; the L.H. or R.H. “fasten” switch at
“ON” position) when the door is closed with the
ignition switch in the “ON” position, the belt
automatically moves to the fastening position.
For the period between the initiation and com-
pletion of the belt’s motion in the fastening
direction, the seat belt warning light either stays
lit or blinks.
Belt Releasing Motion
(1) When the belt is not in the release position, the
L.H. or R.H. release switch is in the “ON”
position, and the left or right door is opened, the
belt will automatically move to the release
position if the ignition switch is at either the
“ON”,“LOCK” or “ACC” position.
For the belt at the driver’s seat side moveover,
the belt will automatically move to the release
position if the
key is taken out while the belt is
fastened.
The buzzer sounds for approximately 0.7 secondsince the start of thebelt’s motion.When the belt is completely fastened, the
“fasten” switch is switched OFF and the motor
stops.(2) With a lapse of approximately 60 seconds after
the belt has stopped its fastening motion due to
foreign object wedged in the mechanism, the
protective timer of the control unit is activated
causing the motor output to the shut off.
When the belt completes its releasing motion,
the L.H. or R.H. release switch is turned OFF,
and the motor stops.
(2)If the belt is still in the process of releasing with
a lapse of approximately 60 seconds after the
start of motion, the protective timer in control
unit is activated causing the motor output to be
shut off.
At the same time, the buzzer sounds for
approximately 0.7 second.

The warning light flashes if the door is closed, the ignition
switch is at “ON” position and the driver’s or front passenger’sseat “fasten” switch is switched ON (unfastened status).
Warning Alarm when the Driver’s Shoulder Belt is not
FastenedWhen, with the driver’s door closed, the ignition switch ON ant
the slide anchor at the “fasten” position (the “fasten” switch is
OFF), the shoulder belt is not fastened (the outer switch is
switched OFF), the buzzer will sound continuously for approx-
imately 6 seconds and, at the same time, the warning light will
‘flash for approximately 68 seconds.
If, however the shoulder belt is fastened (the outer switch is
switched ON) during that period, the warning light and buzzer
will be switched OFF.Warning Alarm when the Front Seat Passenger’s Shoulder

Note that the warning light when the ignition switch isactivated will also illuminate when the ignition switch is turned
from the “LOCK” or “ACC” position to the “ON” position.
Warning Alarm when the ignition Key is Left in the Ignition
The buzzer will sound continuously when all of these condi-
tions occur simultaneously: the key is in the key cylinder
(key-reminder switch A is switched ON), and the ignition
switch is at the “LOCK” or “ACC” position, and the driver’s
door is open (the door latch switch “open” is switched ON).
