Circuit/System Verification
Ignition ON, observe the temperature display. The
temperature reading should be no more than 5 degrees
from the actual temperature around the vehicle.
Circuit/System Testing
1. Ignition OFF, disconnect the harness connector at
the ambient air temperature sensor.
2. Test for less than 1.0 ohm of resistance between the
low reference circuit and ground.
➢
If greater than 1.0 ohm, test the low reference
circuit for a short to voltage or an open/high
resistance. If the circuit tests normal, replace the
inside rearview mirror.
3. Ignition ON, test for 4.8 - 5.2 volts between the 5-volt
reference circuit and ground.
➢ If less than 4.8 volts, test the 5-volt reference circuit
for a short to ground or an open/high resistance. If
the circuit tests normal, replace the inside rearview
mirror.
➢ If greater than 5.2 volts, tests the 5-volt reference
circuit for a short to voltage. If the circuit tests
normal, replace the inside rearview mirror.
4. Install a 3-amp fused jumper wire between the signal
circuit and the 5-volt reference circuit. Verify the
temperature display is greater than 60
°
C or 140
°
F.
➢
If less than 60
°
C or 140
°
F, test the signal circuit for
a short to ground or an open/high resistance. If the
circuit tests normal, replace the inside rearview
mirror.
5. If all circuits test normal, test or replace the ambient
air temperature sensor.
Component Testing
1. Ignition OFF, disconnect the harness connector at
the ambient air temperature sensor.
2. Measure the resistance of the ambient air
temperature sensor from the sensor signal circuit of
the low reference circuit. Compare the ambient air
temperature sensor resistance reading with the chart
above.
➢
If the resistance is not within the specified range,
replace the ambient air temperature sensor.

Air/Wind Noise
Special tool
J 39570 Chassis Ear
J 41416 Ultrasonic Leak Detector
WARNING
!
Refer to Assistant Driving Caution.
To analyze a reported windnoise condition, test drive the
vehicle to determine the origin of the noise.
Choose a regular route with smooth and straight streets
that run in all 4 directions: North, South, East, and West.
The area should have little traffic or little noise in order to
eliminate interference with the test.
NOTE
Often there is one primary leak source and
one or more secondary leaks that contribute
to the noise condition. Repairing only one of
the contributing leak sources may not
completely repair the total condition but only
reduce the condition.
Drive the vehicle at the speed in which the noise was
noticed, or until the noise is heard. Maintain safe and
legal speeds.
Many of the waterleak diagnosis tests are also used for
the windnoise diagnosis.
Most windnoise is caused either by leaking seals or by
misaligned body surfaces. You can diagnose the
following types of windnoise with the aid of J 41416 or J
39570:
• Wind whistle
• Wind roar
• Wind rush
When moving at highway speeds, air pressure inside the
vehicle becomes greater than the air pressure outside.
When a leak occurs, the escaping air causes a hiss or a
whistle.
Wind roar occurs when air passes over or through an
opening between the 2 body surfaces. To correct the
condition, adjust the alignment to the body surfaces.
Wind rush occurs when air presses over the vehicle's
body, and is related to the aerodynamics of the vehicle.
Wind whistle and wind roar are repairable. Rule out wind
whistle and wind roar before concluding that the wind
noise is due to wind rush.
