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.

AUXILIARY MECHANISM: TEMPERATURE SETTING TRIMMER
The trimmer compensates for differences in range of ±3°C between temperature setting (Temperature control
dial position) and temperature felt by driver.
Operating procedures for this trimmer are as follows:
1. Set temperature at 25°C.
2. Set fan control dial to OFF.
3. Turn ignition switch ON.
4. Set in self-diagnostic mode as follows. Within 10 seconds after starting engine (ignition switch is turned
ON.), press intake switch for at least 5 seconds.
5. Turn temperature control dial as desired. Temperature will change at a rate of 1°C each time a dial is
turned.
When battery cable is disconnected, trimmer operation is canceled. Temperature set becomes that of initial
condition, i.e. 0°C.
AUXILIARY MECHANISM: FOOT POSITION SETTING TRIMMER
Wind distribution ratio in FOOT mode can be set.
Operating procedures for this trimmer are as follows:
1. Set temperature at 25°C.
2. Set fan control dial to AUTO.
3. Turn ignition switch ON.
4. Set in self-diagnostic mode as follows. Within 10 seconds after starting engine (ignition switch is turned
ON.), press intake switch for at least 5 seconds.
5. Turn temperature control dial as desired.

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).

TROUBLE DIAGNOSIS

Sunload Sensor CircuitEJS004YR
COMPONENT DESCRIPTION
The sunload sensor is located on the defroster grille (left side). It
detects sunload entering through windshield by means of a photo
diode. The sensor converts the sunload into a current value which is
then input into the auto amp.
SUNLOAD INPUT PROCESS
The auto amp. also includes a processing circuit which averages the variations in detected sunload over a
period of time. This prevents drastic swings in the ATC system operation due to small or quick variations in
detected sunload.
For example, consider driving along a road bordered by an occasional group of large trees. The sunload
detected by the sunload sensor will vary whenever the trees obstruct the sunlight. The processing circuit aver-
ages the detected sunload over a period of time, so that the (insignificant) effect of the trees momentarily
obstructing the sunlight does not cause any change in the ATC system operation. On the other hand, shortly
after entering a long tunnel, the system will recognize the change in sunload, and the system will react accord-
ingly.
DIAGNOSTIC PROCEDURE FOR SUNLOAD SENSOR
SYMPTOM: Sunload sensor circuit is open or shorted.
LED of A/C switch does not illuminate as a result of performing self-
diagnosis STEP-2.
1. CHECK VOLTAGE BETWEEN SUNLOAD SENSOR AND GROUND
1. Disconnect sunload sensor connector.
2. Turn ignition switch ON.
3. Check voltage between sunload sensor harness connector M74
terminal 1 (OR) and ground.

GENERAL MAINTENANCE

GENERAL MAINTENANCEPFP:00000
General MaintenanceELS000AL
General maintenance includes those items which should be checked during the normal day-to-day operation
of the vehicle. They are essential if the vehicle is to continue operating properly. The owners can perform the
checks and inspections themselves or they can have their NISSAN dealers do them for a nominal charge.
OUTSIDE THE VEHICLE
The maintenance items listed here should be performed from time to time, unless otherwise specified.
INSIDE THE VEHICLE
The maintenance items listed here should be checked on a regular basis, such as when performing periodic maintenance, cleaning the
vehicle, etc.
UNDER THE HOOD AND VEHICLE
The maintenance items listed here should be checked periodically e.g. each time you check the engine oil or refuel.Item Reference page
TiresCheck the pressure with a gauge periodically when at a service station, includ-
ing the spare, and adjust to the specified pressure if necessary. Check carefully
for damage, cuts or excessive wear.—
Windshield wiper
bladesCheck for cracks or wear if not functioning correctly. —
Doors and engine
hoodCheck that all doors, the engine hood, the trunk lid and back door operate prop-
erly. Also ensure that all latches lock securely. Lubricate if necessary. Make sure
that the secondary latch keeps the hood from opening when the primary latch is
released.
When driving in areas using road salt or other corrosive materials, check for
lubrication frequently.BL-12

COMBINATION METERS

COMBINATION METERSPFP:24814
System DescriptionEKS00EGZ
UNIFIED CONTROL METER

Speedometer, odo/trip meter, tachometer, fuel gauge and water temperature gauge are controlled by the
unified meter control unit, which is built into the combination meter.

Digital meter is adopted for odo/trip meter.*
*The record of the odo meter is kept even if the battery cable is disconnected. The record of the trip meter
is erased when the battery cable is disconnected.

Odo/trip meter segments can be checked in diagnosis mode.

Meter/gauge can be checked in diagnosis mode.
HOW TO CHANGE THE DISPLAY FOR ODO/TRIP METER

The vehicle speed signal and the memory signals from the meter memory circuit are processed by the
combination meter and the mileage is displayed.

Ambient temperature indicator indicates signal from ambient sensor processed by combination meter.

Depressing the odo/trip meter switch toggles the mode in the following order.

The odo/trip meter display mode toggling and trip display resetting can be identified by the amount of time
that elapses from pressing the odo/trip meter switch to releasing it.

When resetting with trip A displayed, only trip A display is reset (Trip B operates the same way).
POWER SUPPLY AND GROUND CIRCUIT
Power is supplied at all times

through 10A fuse [No. 28, located in the fuse block (J/B)]

to combination meter terminal 1.
With the ignition switch in the ON or START position, power is supplied

through 10A fuse [No. 11, located in the fuse block (J/B)]

to combination meter terminals 2.
Ground is supplied

to combination meter terminals 21

through body grounds M27 and M70.
WATER TEMPERATURE GAUGE
The water temperature gauge indicates the engine coolant temperature.
ECM provides an engine coolant temperature signal to combination meter for water temperature gauge with
CAN communication line.
