Possible cause Drive condition Service procedure
Opera-
tionDriving immediately after starting engine.The gyro (angular velocity sensor)
needs about 15 seconds after the
engine is started to precisely sense
the angular velocity. Directional
sensing errors will occur if the
vehicle is moved immediately after
starting the engine. The position
marker may indicate inaccurate
position.Wait a few moments between
starting the engine and actually
driving the vehicle.
Continuous driving for long distances (non-stop)When the vehicle is driven continu-
ously without stopping over a long
distance, errors in directional sens-
ing may occur. The position marker
may indicate inaccurate position.Stop the vehicle. Perform
ªSPEED CALIBRATIONº (EL-
409).
Rough or violent drivingWheel spinning (peeling out) or simi-
lar rough driving techniques can
adversely affect sensing accuracy.
The position marker may indicate
inaccurate position.If the position marker does not
move to the correct position
even after the vehicle has been
driven approximately 10 km (6
miles), perform ªADJUST CUR-
RENT LOCATIONº (EL-411).

If current vehicle location is roughly

locate the road that the vehicle is
traveling on. (This is especially true
in an area where there are many
roads.)Perform ªADJUST CURRENT

Transmission Data and Transmission OrderNBHA0014S0802Amplifier data is transmitted consecutively to each of the door motors following the form shown in figure below.
Start: Initial compulsory signal sent to each of the door motors.
Address: Data sent from the auto amplifier is selected according to data-based decisions made by the air mix
door motor and mode door motor.
If the addresses are identical, the opening angle data and error check signals are received by the door motor
LCUs. The LCUs then make the appropriate error decision. If the opening angle data is normal, door control
begins.
If an error exists, the received data is rejected and corrected data received. Finally, door control is based upon
the corrected opening angle data.
Opening angle: Data that shows the indicated door opening angle of each door motor.
Error check: Procedure by which sent and received data is checked for errors. Error data is then compiled.
The error check prevents corrupted data from being used by the air mix door motor and mode door motor.
Error data can be related to the following problems.
IAbnormal electrical frequency
IPoor electrical connections
ISignal leakage from transmission lines
ISignal level fluctuation
Stop signal: At the end of each transmission, a stop operation, in-operation, or internal problem message is
delivered to the auto amplifier. This completes one data transmission and control cycle.
RHA442G
Air Mix Door Control (Automatic Temperature Control)NBHA0014S0803The air mix door is automatically controlled so that in-vehicle temperature is maintained at a predetermined
value by: The temperature setting, ambient temperature, in-vehicle temperature and amount of sunload.

Maintenance of Lubricant Quantity in
Compressor
NBHA0071The lubricant in the compressor circulates through the system with
the refrigerant. Add lubricant to compressor when replacing any
component or after a large gas leakage occurred. It is important to
maintain the specified amount.
If lubricant quantity is not maintained properly, the following mal-
functions may result:
ILack of lubricant: May lead to a seized compressor
IExcessive lubricant: Inadequate cooling (thermal exchange
interference)
LUBRICANTNBHA0071S01Name: Nissan A/C System Oil Type S
Part number: KLH00-PAGS0
CHECKING AND ADJUSTINGNBHA0071S02Adjust the lubricant quantity according to the test group shown
below.
1 CHECK LUBRICANT RETURN OPERATION
Can lubricant return operation be performed?
IA/C system works properly.
IThere is no evidence of a large amount of lubricant leakage.
YesorNo

CHECKING FOR REFRIGERANT LEAKS=NBHA0078IPerform a visual inspection of all refrigeration parts, fittings,
hoses and components for signs of A/C lubricant leakage,
damage and corrosion. A/C lubricant leakage may indicate an
area of refrigerant leakage. Allow extra inspection time in these
areas when using either an electronic refrigerant leak detector
or fluorescent dye leak detector.
IIf dye is observed, confirm the leak with an electronic refriger-
ant leak detector. It is possible a prior leak was repaired and
not properly cleaned.
IWhen searching for leaks, do not stop when one leak is found
but continue to check for additional leaks at all system compo-
nents and connections.
IWhen searching for refrigerant leaks using an electronic leak
detector, move the probe along the suspected leak area at 1
to 2 inches per second and no further than 1/4 inch from the
component.
NOTE:
Moving the electronic leak detector probe slower and closer to
the suspected leak area will improve the chances of finding a
leak.
CHECKING SYSTEM FOR LEAKS USING THE
FLUORESCENT LEAK DETECTOR
NBHA01161. Check A/C system for leaks using the UV lamp and safety
glasses (J-42220) in a low sunlight area (area without windows
preferable). Illuminate all components, fittings and lines. The
dye will appear as a bright green/yellow area at the point of
leakage. Fluorescent dye observed at the evaporator drain
opening indicates an evaporator core assembly (tubes, core or
TXV) leak.
2. If the suspected area is difficult to see, use an adjustable mir-
ror or wipe the area with a clean shop rag or cloth, then check
the cloth with the UV lamp for dye residue.
3. After the leak is repaired, remove any residual dye using dye
cleaner (J-43872) to prevent future misdiagnosis.
4. Perform a system performance check and verify the leak repair
with an approved electronic refrigerant leak detector.
NOTE:
IOther gases in the work area or substances on the A/C
components, for example, anti-freeze, windshield washer
fluid, solvents and lubricants, may falsely trigger the leak
detector. Make sure the surfaces to be checked are clean.
Clean with a dry cloth or blow off with shop air.
IDo not allow the sensor tip of the detector to contact with
any substance. This can also cause false readings and
may damage the detector.
DYE INJECTIONNBHA0117(This procedure is only necessary when re-charging the system or
when the compressor has seized and was replaced.)
1. Check A/C system static (at rest) Pressure. Pressure must be
at least 345 kPa (50 psi).
2. Pour one bottle (1/4 ounce /7.4 cc) of the A/C refrigerant dye
into the injector tool (J-41459).
3. Connect the injector tool to the A/C LOW PRESSURE side
service fitting.
4. Start engine and switch A/C ON.
