OPERATION

LIGHT REMINDER ALARM FUNCTION
1. When the lighting switch is in the ON (TAIL

or HEAD) position, the tail light relay is in the
ON state, so the H signal from the tail light
is input to 

2.

When the ignition switch is in the OFF position,
the H signal of the ignition switch inverted by

 is input to 

3. As a result, when the driver’s door is opened

(door switch ON), the H signal of the door switch
inverted by 

 is input to 

 Then 

outputs H signal.

4. When the H signal output from

 the signal output from 

 also

changes to H signal which operates the detector
circuit. Then the buzzer output causes the tran-
sistor to be ON, and the buzzer sounds continu-
ously to remind the driver that the lights (tail
lights or headlights) are ON.

NOTE
If the ignition key is left inserted with the ignition

switch in the OFF position, even if the conditions
for the light reminder function hold good, the buzzer
will sound intermittently, as the ignition key reminder
alarm function takes precedence.

IGNITION KEY REMINDER TIMER FUNCTION
(1) While the ignition key is inserted in the ignition

switch (key reminder switch OFF), the H signal
of the key reminder switch is input to 

(2) If either front door is open (door switch ON)

at that time, the L signal from the door switch
is reversed to the H signal by NOT and applied

to 

(3) As a result, 

 outputs the H signal and

inputs it to 

(4) If the inside lock knob of the driver’s door is

pushed forward at that time (the door lock actua-

tor LOCK), the H signal from the door lock actua-
tor is applied to 

(5) As a result, 

 outputs the H signal, which

is input to the timer circuit through OR to operate

the timer circuit, turn ON the transistor Tr for
five seconds, and unlock all doors.

(6) If the front passenger’s door is opened and

the inside lock knob is pushed forward (door
lock actuator LOCK) while the ignition key is

inserted in the ignition switch (key reminder

switch OFF) and the driver’s door is locked (door

lockactuator LOCK), 

 outputs the H signal.

The signal is input to the timer circuit through
OR to operate the timer circuit, turning ON the
transistor Tr for five seconds and unlocks all
doors.
