NOTE
This thermometer indicates the ambient temperature in the under side of front bumper member. Under
any one of the following listed conditions, however, even when the ambient temperature goes up, the
thermometer display does not rise so as to correct the rise of the ambient temperature caused by the
radiant heat of the engine. When the ambient temperature drops, the thermometer reading follows the
change in the temperature.
Be sure to bear this in mind when diagnosing trouble.
• The vehicle speed is 30 km/h (18 mph) or lower.
• Vehicle speed signal is faulty.
• The ignition switch is turned on again within 2 hours.

Inspection
S6RW0D9506018
1) Disconnect negative (–) cable from battery.
2) Remove junction block for inspection of rear end
door window defogger relay.
3) Remove rear end door window defogger relay (1)
from junction block (2).
4) Check that there is no continuity between terminal
“c” and “d”. If there is continuity, replace relay.
5) Check that there is continuity between terminals “c”
and “d” when a 12 V battery is connected to
terminals “a” and “b”.
If malfunction is found, replace it with a new one.
Rear End Door Window Defogger Wire
Inspection
S6RW0D9506019
NOTE
• When cleaning rear end door window
glass, use a dry cloth to wipe it along heat
wire (1) direction.
• When cleaning glass, do not use detergent
or abrasive-containing glass cleaner.
• When measuring wire voltage, use a tester
with positive probe (2) wrapped with a tin
foil (3) which should be held down on wire
by finger pressure.

Wire Damage Inspection
1) Start engine.
2) Turn on defogger switch.
3) Measure voltage at the center of each defogger wire
(1), and check defogger wire condition according to
the following table.
If defogger wire open is found, go to next step.
