Fuse
L
Check
SEl.276
a.
If
fuse
is
blown, be sure to eliminate cause of
problem before installing new fuse.
b.
Use
fuse of specified rating. Never
use
fuse of
more than specified rating.
c
Do
not install fuse in oblique direction, always
insert
it
into fuse holder properly.
d. Remove fuse for clock
if
vehicle
is
not used for
a long period
of
time.

Fusible
Link
A
melted fusible link can
be
detected either by
visual inspection or by feeling with finger tip.
If
Its
condition
is
questionable, use circuit tester or
test
lamp
I
SEL641D
CAUTION.
a.
If
fusible
link
should melt,
it
is
possible that
critical circuit (power supply or large current
carrying circuit)
is
shorted
In
such
a
case, care-
fully
check and eliminate
cause
of problem.
b. Never wrap periphery
of
fusible
link
with vinyl
tape Extreme care should be taken wlth
this
link to ensure
that
it
does not come into con-
tact with any other wiring harness or vinyl or
rubber parts.

CAUTION:
a.
If
it
becomes necessary to start the engine wlth
a
booster battery and jumper cables,
use
a
12-volt booster battery.
b. After connecting battery cables, ensure
that
they
are
tightly clamped to battery terminals for good
contact
c Never add distilled water through the hole used to check specific gravity
How
to Handle Battery
METHODS
OF
PREVENTING OVER-
DISCHARGE
The following precautions must be taken to pre-
vent over-discharging
a
battery
The battery surface (particularly
its
top)
should always be kept clean and dry
rKeep
clem
and
dry
If the top surface of
a
battery
is
wet with elec-
trolyte or water, leakage current will cause the
battery to discharge Always keep the battery
clean and dry
When the vehicle
is
not going to be used over
a
long period of time, disconnect the negative
battery terminal
(If
the
vehicle has an extend-
ed storage switch, turn
it
off
)
Remove
negative
terrnlnal
SEL712E
Check the charge condition of the battery

@
Periodically check the specific gravity of the
electrolyte Keep
a
close check on charge
condition to prevent over-discharge
CHECKING ELECTROLYTE LEVEL
WARNING
Do
not allow battety fluid to come
in
contact with
skin,
eyes,
fabrics,
or
painted surfaces. After
touching a battery, do not touch
or
rub your
eyes
until
you
have thoroughly washed your hands.
If
the acid contacts the
eyes,
skin or clothing, imme-
diately
flush
with water for
15
minutes and seek
medical attention
Normally the battery does not require additional
water However, when the battery
is
used under
severe conditions, adding distilled water may be
necessary during the battery life
To
maintain serviceability,
a
perforated line has
been added to the battery caution label.

SULPHATION
When
a
battery has been left unattended for
a
long
period of time and has
a
specific gravity of less
than
1
100,
it will be completely discharged, result-
ing in sulphation
on
the cell plates
Compared with
a
battery discharged under normal
conditions, the current flow in
a
"sulphated" bat-
tery
is
not
as
smooth although
its
voltage
is
high
during the initial
stage
of charging.

Aiming Adjustment
When performing headlamp aiming adjustment, use
an aiming machine, aiming wall screen or headlamp
tester.
For operating instructions
of
any aimer,
it
should be in good repair, calibrated and used ac-
cording to respective operation manuals supplied
with the unit.
If
aimer
is
not available, aiming adjustment can
be
done
as
follows
For
details,
refer to the regulations
in
your own
country
CAUTION.
a.
Keep
all
tires inflated to correct pressures
b
Place vehicle
and
tester on the same flat
sur-
face.
c. Ensure
that
there
is
no load
in
vehicle (coolant,
engine oil filled up to correct level and full fuel
tank) other
than
the driver (or equivalent
weight placed
in
driver's position).

Self-check
Digital type combination meter consists of three
units:
a
control unit, power unit, and display unit
In order to judge if there
is
a
defect in the meter
and which unit
is
malfunctioning, troubleshooting
should be performed by using the following two
types of self-check functions built into the meter
For details, refer to "Trouble-shooting".
DISPLAY CHECK
This
is
used
to check for an open circuit in each
segment of the display and
a
short circuit between
segments.
(1)
While pushing trip reset switch
A,
turn igni-
tion switch from
"OFF"
to
"ON".
Trip reset
switch
A
should remain pushed in until self-
check operation starts.
(2)
Meter
starts
to automatically perform self-
check. Segments for meters and gauges should
illuminate one after another.
(3)
If any particular segment remains off, combina-
tion meter itself
is
faulty
SE L143J
A
display check
will
be cancalled and
the
normal
display restarted in the following
cases:
0
If
the vehicle has operated during the display
check.
0
If
a
series of display check items have been
completed.
PRE-PROGRAMED SIGNAL CHECK
This
is
used
to check for
a
defect in the meter

The steering wheel switch system
uses
an acryl-
ic optical ring, and this optical ring functions
in the same way
as
optical fiber
The optical ring
is
built in the slip ring
The
slip
ring must not be disassembled.

3
Disconnect the battery ground cable
Remove the horn pad, horn cover, and both
sections of the steering shell cover
Disconnect the steering switch transmitter har-
ness connector from the rear of the combina-
tion switch.
4
Remove the steering wheel, using the tool and
procedure described in the ST section.
5
Apply the low temperature grease to the steer-
ing column shaft bearing
as
follows.
1)
Place the turn signal switch in neutral position
to prevent
grease
from getting on the turn

nal cancel cam.
2)
Carefully apply approximately

To
facilitate application of the grease, a cone of
paper or vinyl film
is
suggested.
3) Temporarily install the steering wheel Insure
that the projected portion of the slip ring
fits
in the recessed portion of the combination
switch Turn the steering wheel fully to the
left
and right
a
couple of times, taking care to pre-
vent damage to the projected portion of the
slip ring
4)
Remove the steering wheel
5)
Repeat steps b, c, and d
6)
Make sure that
grease
is
applted to the entire
bearing
6
Install the steering wheel on the shaft in
a
straight ahead position
Be
sure that the pro-
jected portion of the slip ring
fits
in the recess-
ed portion of the combination switch
