Mitsubishi MOTORS Laser 1991, Service Manual, Page: 226 / 320

8-226
Battery voltage is always applied to the lighting
switch through multi-purpose fuse
When the lighting switch is set at the “Head”
position, current flows through the passing
control relay, pop-up motor (up-switch), pop-up
motor relay (coil), and ground, closing the pop-up
motor relay contacts.
After flowing through the closed pop-up motor
relay contacts, current flows through the pop-up
motor to ground.
The pop-up motor starts operating to raise the
retractable headlight.
Once the pop-up motor has revolved up to its UP
limit, the switch inside the motor switches its
contact from the UP side to the DOWN side.
This operation of the switch causes the circuit
leading to the pop-up motor relay
to open
and the pop-up motor stops, maintaining the
retractable headlight in its raised position.
When the lighting switch is set at the “OFF” or
“Tail” position, current flows through the lighting
switch, pop-up switch, passing control relay,
pop-up motor (down-switch), pop-up motor relay
(coil), and ground, closing the pop-up motor relay
contacts.
After flowing through the closed pop-up motor
relay contacts, current flows through the pop-up
motor to ground. The pop-up motor begins
operating to retract the headlight.
Once the pop-up motor has revolved up to its
DOWN limit, the switch inside the motor
switches its contact from the DOWN side to the
UP side, and the motor stops, maintaining the
headlight in its retracted position.
When the pop-up switch is set at “ON”, current
flows through multi-purpose fuse lighting
switch, pop-up switch, passing control relay,
pop-up motor (up-switch), pop-up motor relay
(coil), and ground. The retractable headlights
rises just as it does when the lighting switch is set
at the “Head” position.
When the pop-up switch is set at “OFF”, current
flows through the pop-up switch, the passing
control relay, the pop-up motor (down-switch),
the pop-up motor relay (coil), and ground. The
headlight retracts just as it does when the lighting
switch is set at the “OFF” or “Tail” position.
1. Headlights do not rise
(1) They rise only when the lighting switch is
operated.
Check the pop-up switch.
(2) They rise only when the pop-up switch is
operated.
Check the lighting switch.
2. Headlights do not retract
Check the pop-up switch.
Check the passing control relay.
3. One headlight does not move
Check the pop-up motor relay.
Check the pop-up motor.
NOTE
For information concerning the pop-up motor relay
and passing control relay, refer to 245.
