REAR DEFOGGER HEAT WIRES
w CAUTION:
• Heat wires are printed on the inner side of
the rear glass.
To clean, use a
soft cloth and wipe horizon­
tally along the wires.
• Never use glass cleaner or equivalent.
~ INSPECTION
It~ I Measure the voltage of heat wire.
Repair the heat wire
when the result of inspection
is found abnormal.
'f CAUTION:
• When measuring voltage, wind a piece of
tin foil around the tip of the negative probe
and press
the foil against the wire with your
finger (Fig. 8-129).
1. Turn the starter switch on.
2. Turn the rear defogger switch on.
3. Measure the voltage between the three points
on
the heat wire and the(-) terminal with a voltmeter.
4. Check that the voltage becomes smaller from ®
to @to© (Fig. 8-130).
5. If there is a place where the voltage suddenly
changes
to OV, there is a OPEN CIRCUIT between
there and the
prior point.

TURN SIGNAL LIGHT, HAZARD WARNING LIGHT,
CORNERING LIGHT,
BACKUP LIGHT AND HORN
GENERAL DESCRIPTION
The circuit consists of the starter switch, lighting switch, turn signal/cornering switch (combination witch),
turn signal light, cornering light, hazard warning switch, flasher unit, mode switch (A/T), backup light switch,
backup light, horn switch and horn.
When
turning on the respective switches with the starter switch on, the turn signal light and the back p light
will operate. When the turn signal light is flashing, the indicator light in the meter also starts flash in .
When the hazard
warning switch is turned on, the current flows to the flasher unit through the hazard
warning switch to cause the hazard warning light to flash, independent of the position of the starter switch.
At the same time, the indicator lights in the meter also start flashing.
When the
turn signal lever is set in either the left or right direction while the headlight is on, the co nering
switch incorporated
into the combination switch is activated to illuminate the appropriate cornering I ght.
When the horn switch is turned on, (independent
of the position of the starter switch) the relay is acti ated to
sound the horn.
