Light Reminder Alarm Function - Mitsubishi Eclipse Technical Information Manual

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 AND2.
2. When the ignition switch is in the OFF position,
the H signal of the ignition switch inverted by
3. As a result, when the driver's door is opened
(door switch ON), the H signal of the door switch
inverted by NOT2 is input to ANDl. Then AND1
outputs H signal.

4. When the H signal output from AND1 is input
to AND2, the signal output from AND2 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.
