SPEEDOMETER
ABS actuator and electric unit (control unit) provides a vehicle speed signal to the unified meter and A/C amp.
with CAN communication line. After unified meter and A/C amp. received the vehicle speed signal, it changes
the signal to 8 pulse signal and provides the 8 pulse signal to the combination meter for the speedometer.
TACHOMETER
The tachometer indicates engine speed in revolutions per minute (rpm).
ECM provides an engine speed signal to unified meter and A/C amp. with CAN communication line. Unified
meter and A/C amp. provides an engine speed signal to combination meter for tachometer with communica-
tion line between unified meter and A/C amp. and combination meter.
LOW WATER TEMPERATURE INDICATOR LAMP, HIGH WATER TEMPERATURE WARNING
LAMP
ECM converts water temperature signal from water temperature sensor into data and transmits the data to uni-
fied meter and A/C amp. with CAN communication line. Unified meter and A/C amp. transmit the received
water temperature signal to the combination meter with communication line between unified meter and A/C
amp. and combination meter. Combination meter turns on/off low water temperature indicator lamp or high
water temperature warning lamp through the received water temperature signal.
FUEL GAUGE
The fuel gauge indicates the approximate fuel level in the fuel tank.
The fuel gauge is regulated by a variable ground signal supplied
from unified meter and A/C amp. terminal 36
through the fuel level sensor unit and fuel pump terminals 5 and 2
to unified meter and A/C amp. terminal 28 for the fuel gauge.
Unified meter and A/C amp. provides a fuel level signal to combination meter for fuel gauge with communica-
tion line between unified meter and A/C amp. and combination meter.

3. CHECK FUEL LEVEL SENSOR SIGNAL CIRCUIT
1. Disconnect unified meter and A/C amp. connector and fuel level sensor unit and fuel pump connector.
2. Check continuity between unified meter and A/C amp. harness
connector M42 terminal 28 and fuel level sensor unit and fuel
pump harness connector B223 terminal 2.
3. Check continuity between unified meter and A/C amp. harness
connector M42 terminal 28 and ground.
OK or NG
OK >> GO TO 4.
NG >> Repair harness or connector.
4. CHECK FUEL LEVEL SENSOR GROUND CIRCUIT
1. Check continuity between fuel level sensor unit and fuel pump
harness connector B223 terminal 5 and unified meter and A/C
amp. harness connector M42 terminal 36.
2. Check continuity between fuel level sensor unit and fuel pump
harness connector B223 terminal 5 and ground.
OK or NG
OK >> GO TO 5.
NG >> Repair harness or connector.
5. CHECK INSTALLATION CONDITION
Check fuel level sensor unit and fuel pump installation, and check whether the float arm interferes or binds
with any of the internal components in the fuel tank.
OK or NG
OK >> Replace unified meter and A/C amp. Refer to DI-34, "Removal and Installation of Unified Meter
and A/C Amp." .
NG >> Install the fuel level sensor unit and fuel pump properly.
Fuel Gauge Does Not Move to FULL positionBKS001SG
1. QUESTION 1
Does it take a long time for the pointer to move to FULL position?
YES >> GO TO 2.
NO >> GO TO 3.
2. QUESTION 2
Was the vehicle fueled with the ignition switch ON?
YES >> Be sure to fuel the vehicle with the ignition switch OFF. Otherwise, it will take a long time to move
to FULL position because of the characteristic of the fuel gauge.
NO >> GO TO 3.28 – 2 : Continuity should exist.
28 – Ground : Continuity should not exist.
SKIA8723E
5 – 36 : Continuity should exist.
5 – Ground : Continuity should not exist.

Is the vehicle parked on an incline?
YES >> Check the fuel level indication with vehicle on a level surface.
NO >> GO TO 4.
4. QUESTION 4
During driving, does the fuel gauge pointer move gradually toward EMPTY position?
YES >> Check the fuel level sensor unit and fuel pump. Refer to DI-24, "CHECK FUEL LEVEL SENSOR

PRECAUTIONS
After performing each TROUBLE DIAGNOSIS, perform DTC
Confirmation Procedure or Overall Function Check.
The DTC should not be displayed in the DTC Confirmation
Procedure if the repair is completed. The Overall Function
Check should be a good result if the repair is completed.
When measuring ECM signals with a circuit tester, never
allow the two tester probes to contact.
Accidental contact of probes will cause a short circuit and
damage the ECM power transistor.
Do not use ECM ground terminals when measuring input/
output voltage. Doing so may result in damage to the ECM's
transistor. Use a ground other than ECM terminals, such as
the ground.
Do not operate fuel pump when there is no fuel in lines.
Tighten fuel hose clamps to the specified torque.

BASIC SERVICE PROCEDURE
2. Perform “FUEL PRESSURE RELEASE” in “WORK SUPPORT”
mode with CONSULT-II.
3. Start engine.
4. After engine stalls, crank it two or three times to release all fuel
pressure.
5. Turn ignition switch OFF.
Without CONSULT-II
1. Remove fuel pump fuse located in IPDM E/R.
2. Start engine.
3. After engine stalls, crank it two or three times to release all fuel
pressure.
4. Turn ignition switch OFF.
5. Reinstall fuel pump fuse after servicing fuel system.
FUEL PRESSURE CHECK
Before disconnecting fuel line, release fuel pressure from fuel line to eliminate danger.
NOTE:
Prepare pans or saucers under the disconnected fuel line because the fuel may spill out. The fuel pres-
sure cannot be completely released because J31 models do not have fuel return system.
CAUTION:
The fuel hose connection method used when taking fuel pressure check must not be used for
other purposes.
Be careful not to scratch or put debris around connection area when servicing, so that the quick
connector maintains sealability with O-rings inside.
When installing fuel hose quick connector, refer to EM-19, "INTAKE MANIFOLD" .
1. Release fuel pressure to zero. Refer to EC-49, "
FUEL PRESSURE RELEASE" .
2. Prepare fuel hose and fuel hose clamp for fuel pressure check, and connect fuel pressure gauge.
Use suitable fuel hose for fuel pressure check (genuine NISSAN fuel hose without quick connector).
To avoid unnecessary force or tension to hose, use moderately long fuel hose for fuel pressure check.
Do not use the fuel hose for checking fuel pressure with damage or cracks on it.
Use Pressure Gauge to check fuel pressure.
3. Remove fuel hose. Refer to EM-19, "
INTAKE MANIFOLD" .
Do not twist or kink fuel hose because it is plastic hose.
Do not remove fuel hose from quick connector.
Keep the original fuel hose to be free from intrusion of dust or foreign substances with a suitable cover.

4. Install the fuel pressure gauge as shown in the figure.
Wipe off oil or dirt from hose insertion part using cloth moist-
ened with gasoline.
Apply proper amount of gasoline between top of the fuel tube
and No.1 spool.
Insert fuel hose for fuel pressure check until it touches the
No.1 spool on fuel tube.
Use NISSAN genuine hose clamp (part number: 16439
N4710 or 16439 40U00).
When reconnecting fuel line, always use new clamps.
When reconnecting fuel hose, check the original fuel hose for
damage and abnormality.
Use a torque driver to tighten clamps.
Install hose clamp to the position within 1 - 2 mm (0.04 - 0.08
in).
Make sure that clamp screw does not contact adjacent parts.
5. After connecting fuel hose for fuel pressure check, pull the hose
with a force of approximately 98 N (10 kg, 22 lb) to confirm fuel
tube does not come off.
6. Turn ignition switch ON, and check for fuel leakage.
7. Start engine and check for fuel leakage.
8. Read the indication of fuel pressure gauge.
Do not perform fuel pressure check with system operating. Fuel pressure gauge may indicate false
readings.
During fuel pressure check, confirm for fuel leakage from fuel connection every 3 minutes.
9. If result is unsatisfactory, go to next step.
10. Check the following.
Fuel hoses and fuel tubes for clogging
Fuel filter for clogging
Fuel pump
Fuel pressure regulator for clogging
If OK, replace fuel pressure regulator.
If NG, repair or replace.Tightening
