2003 NISSAN TEANA change time

FOREWORD
This manual contains maintenance and repair procedures for the NISSAN
TEANA, model J31 series.
In order to assure your safety and the efficient functioning of the vehicle,
this manual should be read thoroughly. It is especially important that the
PRECAUTIONS in the GI section be completely understood before starting
any repair task.
All information in this manual is based on the latest product information
at the time of publication. The right is reserved to make changes in speci-
fications and methods at any time without notice.
IMPORTANT SAFETY NOTICE
The proper performance of service is essential for both the safety of the
technician and the efficient functioning of the vehicle.
The service methods in this Service Manual are described in such a man-
ner that the service may be performed safely and accurately.
Service varies with the procedures used, the skills of the technician and the
tools and parts available. Accordingly, anyone using service procedures,
tools or parts which are not specifically recommended by NISSAN must
first be completely satisfied that neither personal safety nor the vehicle's
safety will be jeopardized by the service method selected.

DTC Confirmation ProcedureBCS00134
CAUTION:

Always drive vehicle at a safe speed.

If performing this “DTC Confirmation Procedure” again, always turn ignition switch OFF and wait
at least 10 seconds before continuing.
TESTING CONDITION:
Always drive vehicle on a level road to improve the accuracy of test.
After the repair, perform the following procedure to confirm that the malfunction is eliminated.
WITH CONSULT-II
1. Start engine and select “DATA MONITOR” mode for “A/T” with
CONSULT-II.
2. Make sure that output voltage of A/T fluid temperature sensor is
within the range below.
FLUID TEMP SE: 0.4 - 1.5 V
If out of range, drive vehicle to decrease the voltage (warm up
the fluid) or stop engine to increase the voltage (cool down the
fluid).
3. Select “1ST GR FNCTN P0731” of “DTC WORK SUPPORT”
mode for “A/T” with CONSULT-II and touch “START”.
4. Accelerate vehicle to 20 to 25 km/h (12 to 16 MPH) under the following condition and release accelerator
pedal completely.
THROTTLE POSI: Less than 1.0/8 (at all times during step 4)
SLCT LVR POSI: “D” position
–Make sure that “GEAR” shows “2” after releasing pedal.
5. Depress accelerator pedal to WOT (more than 7.0/8 of “THROTTLE POSI”) quickly from a speed of 20 to
25 km/h (12 to 16 MPH) until “TESTING” changes to “STOP VEHICLE” or “COMPLETED”. (It will take
approximately 3 seconds.)
If the check result NG appears on CONSULT-II screen, go to AT- 1 3 8 , "
Diagnostic Procedure" .
If “STOP VEHICLE” appears on CONSULT-II screen, go to the following step.
–Make sure that “GEAR” shows “1” when depressing accelerator pedal to WOT.
–If “TESTING” does not appear on CONSULT-II for a long time, select “SELF-DIAG RESULTS” for
“A/T”. In case a 1st trip DTC other than “A/T 1ST GR FNCTN” is shown, refer to applicable “TROU-
BLE DIAGNOSIS FOR DTC”.
6. Stop vehicle.
7. Follow the instruction displayed. (Check for normal shifting referring to the table below.)
8. Make sure that “OK” is displayed. (If “NG” is displayed, refer to AT- 1 3 8 , "
Diagnostic Procedure" .)
Refer to AT- 5 4 , "

SERVICE HOSES
Be certain that the service hoses display the markings described
(colored hose with black stripe). All hoses must include positive shut-
off devices (either manual or automatic) near the end of the hoses
opposite the manifold gauge.
SERVICE COUPLERS
Never attempt to connect HFC-134a (R-134a) service couplers to a
CFC-12 (R-12) A/C system. The HFC-134a (R-134a) couplers will
not properly connect to the CFC-12 (R-12) system. However, if an
improper connection is attempted, discharging and contamination
may occur.
REFRIGERANT WEIGHT SCALE
Verify that no refrigerant other than HFC-134a (R-134a) and speci-
fied lubricants have been used with the scale. If the scale controls
refrigerant flow electronically, the hose fitting must be 1/2
″ -16
ACME.
CALIBRATING ACR4 WEIGHT SCALE
Calibrate the scale every three months.
To calibrate the weight scale on the ACR4:
1. Press Shift/Reset and Enter at the same time.
2. Press 8787 . “A1 ” will be displayed.
3. Remove all weight from the scale.
4. Press 0 , then press Enter . “0.00 ” will be displayed and change to “A2 ”.
5. Place a known weight (dumbbell or similar weight), between 4.5 and 8.6 kg (10 and 19 lb.) on the center
of the weight scale.
6. Enter the known weight using four digits. (Example 10 lb. = 10.00, 10.5 lb. = 10.50)
7. Press Enter — the display returns to the vacuum mode.
8. Press Shift/Reset and Enter at the same time.
9. Press 6 — the known weight on the scale is displayed.
10. Remove the known weight from the scale. “0.00 ” will be displayed.
11 . P r e s s Shift/Reset to return the ACR4 to the program mode.

TROUBLE DIAGNOSIS

AUXILIARY MECHANISM: TEMPERATURE SETTING TRIMMER
The trimmer compensates for differences in range of ±3°C between temperature setting (displayed digitally)
and temperature felt by customer.
Operating procedures for this trimmer are as follows:
1. Begin Self-diagnosis STEP-5 mode. Refer to AT C - 4 6 , "
Self-diagnosis Function" .
2. Press fan control switch (UP) to set system in auxiliary mode.
3. Display shows “61” in auxiliary mechanism. It takes approximately 3 seconds to enable setting operation.
4. Press temperature control switch (driver side) as desired. Temperature will change at a rate of 0.5°C each
time a switch is pressed.
CAUTION:
A decimal point is not indicated during a setup of temperature compensation.
When battery cable is disconnected or battery voltage below 10 V, trimmer operation is canceled. Temperature
set becomes that of initial condition, i.e. 0°C.

TROUBLE DIAGNOSIS

TROUBLE DIAGNOSIS FOR UNUSUAL PRESSURE
Whenever system’s high and/or low side pressure(s) is/are unusual, diagnose using a manifold gauge. The
marker above the gauge scale in the following tables indicates the standard (usual) pressure range. Since the
standard (usual) pressure, however, differs from vehicle to vehicle, refer to above table (Ambient air tempera-
ture-to-operating pressure table).
Both High- and Low-pressure Sides are Too High
High-pressure Side is Too High and Low-pressure Side is Too Low
Gauge indication Refrigerant cycle Probable cause Corrective action
Both high- and low-pressure sides
are too high.The pressure returns to nor-
mal soon after water is
splashed on the condenser.Excessive refrigerant charge
in refrigeration cycle.Reduce refrigerant until speci-
fied pressure is obtained.
Air suction by cooling fan is
insufficient.Insufficient condenser cooling
performance.
↓
1. Condenser fins are clogged.
2. Improper fan rotation of
cooling fan.

Clean condenser.

Check and repair cooling fan
if necessary.

Low-pressure pipe is not
cold.

When compressor is
stopped high-pressure
value quickly drops by
approximately 196 kPa
(1.96 bar, 2 kg/cm
2 , 28
psi). It then decreases
gradually thereafter.Poor heat exchange in con-
denser.
(After compressor operation
stops, high-pressure
decreases too slowly.)
↓
Air in refrigeration cycle.Evacuate repeatedly and
recharge system.
Engine tends to overheat.Engine cooling systems mal-
function.Check and repair each engine
cooling system.

An area of the low-pres-
sure pipe is colder than
areas near the evaporator
outlet.

Low-pressure pipe is
sometimes covered with
frost.

Excessive liquid refrigerant
on low-pressure side.

Excessive refrigerant dis-
charge flow.

Expansion valve is open a
little compared with the
specification.
↓
Improper expansion valve
adjustment.Replace expansion valve.
AC359A
Gauge indication Refrigerant cycle Probable cause Corrective action
High-pressure side is too high and
low-pressure side is too low.
Upper side of condenser and
high-pressure side are hot,
however, liquid tank is not so
hot.High-pressure tube or parts
located between compressor
and condenser are clogged or
crushed.

Check and repair or replace
malfunctioning parts.

Check lubricant for contami-
nation.
