6. Prepare the nozzle of the sealant gun so that it has
a flange that can run along the edge of the glass,
and a V from which the sealant can flow. Once the
primer is dry, apply the sealant around the entire
circumference to fill the gap between the dam and
the edge of the glass with a ridge of sealant 11
mm (0.43 in) high.
Keep the bead of sealant smooth and even,
reshaping it where necessary with a spatula.

7. Lift the glass into place. Push it in lightly toward
the vehicle to compress the sealant.
Caution
Open the windows to prevent the glass from
being pushed out by air pressure if a door is
closed.

8. Use a scraper to smooth away any sealant that
oozes out. Add more sealant to any points of poor
contact.
9. Check for water leaks. If a leak is found, wipe the
water off well and add repair seal (B001 77 739)
where needed.

2. Air-mix door control wire
a. Set TEMP lever at MAX—COLD position.
b. Connect the control wire and clamp it with the
shutter lever on the heater unit all the way to the
right side.
Caution
Move the temperature control lever to check
that the wire is secured. Also, check that it
moves the full stroke between HOT and COLD.

3. Mode control wire
a. Set MODE control lever to DEF position.
b. Connect the control wire and clamp it with the
shutter lever on the heater unit at its closest point.
Caution
Move the mode lever to check that the wire
is secured. Also, check that it moves the full
stroke between DEF and VENT.

, REC-FRESH air selector wire
a. Set the selector lever to REC position.
b. Connect the control wire and clamp it with the
shutter lever on the blower unit at its closest
point.
Caution
Move the recirculate-fresh air switch lever to
check that the wire is secured. Also, check
that it moves the full stroke between REC and
FRESH.

3. Set the SST to the resistance values shown in the
figure.
4. Turn the ignition switch ON, and check that the
needle indicator displays the correct values.
If the needle displays correctly, check the gauge
unit. If not, replace the fuel gauge in the meter or
repair the wiring harness.
Caution
a) Continue the above checks for at least two
minutes each to correctly judge the con-
dition.
b)The allowable indication error is twice the
width of the needle.
Water Temperature Gauge
1. Disconnect the connector from the water thermo
sensor.
2. Connect the red lead of the SST to the connec-
tor, and the black lead to a body ground.
3. Set the SST to the resistance values shown in the
figure.
4. Turn the ignition switch ON, and check that the
needle indicator displays the correct values.
If the needle displays the correct values, the trou-
ble is in the gauge unit; if not, the trouble is in the
meter or the wiring harness.
Caution
a) Continue the above checks for at least two
minutes each to correctly judge the con-
dition.
b)The allowable indication error is twice the
width of the needle.
INSPECTION OF DIGITAL METER
Speedometer
1. Using a speedometer tester, check the speedom-
eter for allowable indication error, and check the
operation of the odometer. Replace the meter as-
sembly if necessary.
2. Check the speedometer for fluctuation and/or ab-
normal noise.
Caution
a) If significant fluctuation occurs or the
speedometer does not move at all, remove
the speedometer cable. If normal, replace
the digital meter assembly.
b)Tire wear and improper inflation will in-
crease speedometer error.

3. Set the SST to the resistance values shown in the
following table.
4. Turn the ignition switch ON and check that the seg-
ment displays the correct values. If the segment
displays the correct values, check the gauge unit.
If not, replace the digital meter assembly or repair
wiring harness.
Caution
Continue the above checks for at least two
minutes each to correctly judge the condition.

INSPECTION OF METER SENDER
Fuel tank unit (except 4WS model)
1. Disconnect the connector from the fuel tank unit.
2. Remove the fuel tank unit from the tank.
3. Connect an ohmmeter to terminal "b" of con-
nector.
4. Move the unit arm slowly from point (F) to point
(E), and read the resistance values. If not as speci-
fied, replace the unit.
