OPERATION
Functions of the Lighting Switch
NOOIHAA
Battery voltage is always applied to the lighting
switch through fuse No. 4.
When the lighting switch is set at the "2"
position, current flows through the pop-up
motor (sensor), 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 sensor inside the motor switches its
contact from the UP side to the DOWN side.
This operation of the sensor causes the circuit
leading to the pop-up motor relay (coil) 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
"1 " position, current flows through the lighting
switch, passing control relay, pop-up switch,
passing control relay, pop-up motor (sensor),
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 sensor 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.
Functions of the Pop-up Switch
l
When the pop-up switch is set at "ON", current
flows through fuse No. 4, lighting switch,
passing control relay, pop-up switch, pop-up
motor (sensor), pop-up motor relay (coil), and
ground. The retractable headlights rises just asit
does when the lighting switch is set at the "2"
position.
l
When the pop-up switch is set at "OFF", current
flows through the pop-up switch, the passing
control relay, the pop-up motor (sensor), 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 "1"
position.
Functions of the Passing Switch
By setting the passing switch at the "ON"
position while the ignition -switch is turned to
"ACC" or "ON", current flows through fuse No.
9, passing relay, passing control relay, passing
switch, and ground, closing the passing control
relay contacts.
Once the passing control relay contacts have
closed, current flows through fuse No. 4, light-
ing switch, passing control relay, pop-up motor
(sensor), pop-up motor relay (coil), and ground,
and the retractable headlight rises just as it does
wh.en the lighting switch is set at "2".
TROUBLESHOOTING HINTS
1. Headlights do not rise
1) They rise only when the lighting switch is
operated.
l
Check the pop-up switch.
l
Check the passing control relay.
2) They rise only when the pop-up switch is
operated
l
Check the lighting switch.
2. Headlights
do not retract
l
Check the pop-up switch.
l
Check the passing control relay.
3. One headlight does not move
l
Check the pop-up motor relay.
l
Check the pop-up motor.
