WARNING:
When replacing fuel line parts, be sure to observe the following:
IDisplay a ªCAUTION:INFLAMMABLEº sign in workshop.
IBe sure to furnish workshop with a CO
2fire extinguisher service.
IDo not smoke while servicing fuel system. Keep open flames and sparks away from work area.
IBe sure to disconnect battery ground cable before conducting operations.
IPour drained fuel into an explosion-proof container, then ensure container lid is installed securely.
CAUTION:
IFor ECM models, release fuel pressure from fuel line. Refer to EC section (ªFuel Pressure Releaseº,
ªBASIC SERVICE PROCEDUREº).
IDo not disconnect any fuel line unless absolutely necessary.
IPlug hose and pipe openings to prevent entry of dust or dirt.
IAlways replace top lid seal and hose clamps with new ones.
IDo not kink or twist hoses and tubes during installation.
IDo not tighten hose clamps excessively because this could cause damage to the hose.
IEnsure fuel check valve is installed in the correct orientation.
IRefer to EC section (ªFUEL CHECK VALVEº, ªEVAPORATIVE EMISSION SYSTEMº).
IAfter installation, run engine and check for fuel leaks at connections.
Fuel Pump and Gauge
REMOVAL
Petrol engine
1. Release fuel pressure from fuel line.
Refer to EC section (ªFuel Pressure Releaseº, ªBASIC SER-
VICE PROCEDUREº).
2. Remove inspection hole cover located under the luggage com-
partment carpet.
3. Remove fuel filler lid.
4. Disconnect fuel outlet, return tube and connectors.
CAUTION:
Mark the fuel tubes to ensure correct position during installa-
tion.
5. Remove the fuel gauge assembly and disconnect tubes and
connector.

SERVICE HOSES
Be certain that the service hoses display the markings described
(colored hose with black stripe). Be certain that all hoses 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
an CFC-12 (R-12) A/C system. Although the HFC-134a (R-134a)
couplers will not secure on to the CFC-12 (R-12) system, CFC-12
(R-12) refrigerant and lubricant will be discharged into the HFC-
134a (R-134a) coupler, causing contamination.
Shut off valve rotation A/C service valve
Clockwise Open
Counterclockwise Close
REFRIGERANT WEIGHT SCALE
If the scale allows electronic control of the flow of refrigerant
through the scale, be certain that the hose fitting size is 1/2²-16
ACME, and that no refrigerant other than HFC-134a (R-134a)
(along with only specified lubricant) has been used with the scale.
CHARGING CYLINDER
The charging cylinder is not recommended because refrigerant
may be vented into the air from the top valve of the cylinder when
filling the cylinder with refrigerant. Additionally, the accuracy of the
cylinder is generally less than that of an electronic scale or of qual-
ity recycle/recharge equipment.

Trouble Diagnoses Introduction
CAUTION:
IDo not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. Spiral cable and wiring harnesses covered with yellow insulation tape either just
before the harness connectors or for the complete harness are related to the SRS.
IDo not attempt to repair, splice or modify the SRS wiring harness. If the harness is damaged,
replace it with a new one.
IKeep ground portion clean.
DIAGNOSIS FUNCTION
The SRS self-diagnosis results can be read by using ªAIR BAGº warning lamp and/or CONSULT-II. The read-
ing of these results is accomplished using one of two modes Ð ªUser modeº and ªDiagnosis modeº.
The User mode is exclusively prepared for the customer (driver). This mode warns the driver of a system
malfunction through the operation of the ªAIR BAGº warning lamp.
The Diagnosis mode allows the technician to locate and inspect the malfunctioning part.
The mode applications for the ªAIR BAGº warning lamp and CONSULT-II are as follows:
User mode Diagnosis mode Display type
ªAIR BAGº warning lamp X X ON-OFF operation
CONSULT-II Ð X Monitoring
NOTE:
Seat belt pre-tensioner malfunction is indicated by ªAIR BAGº warning lamp.
DIAGNOSIS MODE FOR CONSULT-II
IªSELF-DIAG [CURRENT]º
A current self-diagnosis result (also indicated by the number of warning lamp flashes in the Diagnosis
mode) is displayed on the CONSULT-II screen in real time. This refers to a malfunctioning part requiring
repairs.
IªSELF-DIAG [PAST]º
Diagnosis results previously stored in the memory are displayed on the CONSULT-II screen. The stored
results are not erased until memory erasing is executed.
IªTROUBLE DIAG RECORDº
With TROUBLE DIAG RECORD, diagnosis results previously erased by a reset operation can be displayed
on the CONSULT-II screen.
IªECU DISCRIMINATED NO.º
The diagnosis sensor unit for each vehicle model is assigned with its own, individual classification num-
ber (refer to the table below). This number will be displayed on the CONSULT-II screen. When replacing
the diagnosis sensor unit, refer to the part number for the compatibility. After installation, replacement with
a correct unit can be checked by confirming this classification number on the CONSULT-II screen.
For NISSAN MODEL R20, the diagnosis sensor unit classification numbers are as follows:
MODEL ECU DISCRIMINATED NO.
Models with single air bag and seat belt pre-tensioner A928
Models with dual air bags and seat belt pre-tensioner A929
Models with dual air bags, side air bag and seat belt pre-tensioner A930

HOW TO ERASE SELF-DIAGNOSIS RESULTS
With CONSULT-II
IªSELF-DIAG [CURRENT]º
A current self-diagnosis result is displayed on the CONSULT-II screen in real time.
After the malfunction is repaired completely, no malfunction is detected on ªSELF-DIAG [CURRENT]º.
IªSELF-DIAG [PAST]º
Return to the ªSELF-DIAG [CURRENT]º CONSULT-II screen by pushing ªBACKº key of CONSULT-II and
select ªSELF-DIAG [CURRENT]º in SELECT DIAG MODE. Touch ªERASEº in ªSELF-DIAG [CURRENT]º
mode.
NOTE:
If the memory of the malfunction in ªSELF-DIAG [PAST]º is not erased, the User mode shows the sys-
tem malfunction by the operation of the warning lamp even if the malfunction is repaired completely.
IªTROUBLE DIAG RECORDº
The memory of ªTROUBLE DIAG RECORDº cannot be erased.
Without CONSULT-II
After a malfunction is repaired, switch the ignition ªOFFº for at least one second, then back ªONº. Diagnosis
mode returns to the User mode. At that time, the self-diagnostic result is cleared.
