Diagnostic Worksheet
There are many operating conditions that lead to the malfunction
of engine components. A good grasp of such conditions can make
troubleshooting faster and more accurate.
In general, each customer feels differently about a problem. It is
important to fully understand the symptoms or conditions for a
customer complaint.
Utilize a diagnostic worksheet like the one shown below in order to
organize all the information for troubleshooting.

Circuit Inspection
INTRODUCTION
In general, testing electrical circuits is an easy task if it is approached in a logical and organized method. Before
beginning it is important to have all available information on the system to be tested. Also, get a thorough
understanding of system operation. Then you will be able to use the appropriate equipment and follow the
correct test procedure.
You may have to simulate vehicle vibrations while testing electrical components.Gently shakethe wiring
harness or electrical component to do this.
OPEN A circuit is open when there is no continuity through a section of the circuit.
SHORT There are two types of shorts.
+SHORT CIRCUITWhen a circuit contacts another circuit and causes the
normal resistance to change.
+SHORT TO GROUNDWhen a circuit contacts a ground source and grounds the
circuit.
TESTING FOR ``OPENS'' IN THE CIRCUIT
Before you begin to diagnose and test the system, you should rough sketch a schematic of the system. This
will help you to logically walk through the diagnosis process. Drawing the sketch will also reinforce your work-
ing knowledge of the system.
Continuity check method
The continuity check is used to ®nd an open in the circuit. The Digital Multimeter (DMM) set on the resistance
function will indicate an open circuit as over limit (OL, no beep tone or no ohms symbol). Make sure to always
start with the DMM at the highest resistance level.
To help in understanding the diagnosis of open circuits please refer to the schematic above.
1. Disconnect the battery negative cable.
2. Start at one end of the circuit and work your way to the other end. (At the fuse block in this example)
3. Connect one probe of the DMM to the fuse block terminal on the load side.
4. Connect the other probe to the fuse block (power) side of SW1. Little or no resistance will indicate that
portion of the circuit has good continuity. If there were an open in the circuit, the DMM would indicate an
over limit or in®nite resistance condition. (point A)
5. Connect the probes between SW1 and the relay. Little or no resistance will indicate that portion of the cir-
cuit has good continuity. If there were an open in the circuit, the DMM would indicate an over limit or in®-
nite resistance condition. (point B)
6. Connect the probes between the relay and the solenoid. Little or no resistance will indicate that portion of
the circuit has good continuity. If there were an open in the circuit, the DMM would indicate an over limit
or in®nite resistance condition. (point C)
Any circuit can be diagnosed using the approach in the above example.

HOW TO ERASE SELF-DIAGNOSIS RESULTS
With CONSULT
+``SELF-DIAG [CURRENT]''
A current Self-diagnosis result is displayed on the CONSULT screen in real time. After the malfunction is
repaired completely, no malfunction is detected on ``SELF-DIAG [CURRENT]''.
+``SELF-DIAG [PAST]''
Return to the ``SELF-DIAG [CURRENT]'' CONSULT screen by
pushing ``BACK'' key of CONSULT and select ``SELF-DIAG
[CURRENT]'' in ``SELECT DIAG MODE''. Touch ``ERASE'' in
``SELF-DIAG [CURRENT]'' mode.
NOTE:
If the memory of the malfunction in ``SELF-DIAG [PAST]'' is not
erased, the User mode shows the system malfunction by the
operation of the warning lamp even if the malfunction is
repaired completely.
+``TROUBLE DIAG RECORD''
The memory of ``TROUBLE DIAG RECORD'' cannot be erased.
Without CONSULT
After a malfunction is repaired, return to User mode from Diagnosis mode by switching the ignition ``OFF'' for
at least 1 second, then back ``ON''. At that time, the problem code is cleared.
How to Perform Trouble Diagnoses for Quick
and Accurate Repair
A good understanding of the malfunction conditions can make troubleshooting faster and more accurate.
In general, each customer feels differently about a problem. It is important to fully understand the symptoms
or conditions for a customer complaint.

TROUBLE DIAGNOSES Ð Supplemental Restraint System (SRS)
Trouble Diagnoses Introduction (Cont'd)

Supplemental Restraint System (SRS) ``AIR
BAG'' and ``SEAT BELT PRE-TENSIONER''
The Supplemental Restraint System such as ``AIR BAG'' and ``SEAT BELT PRE-TENSIONER'' used along with
a seat belt, helps to reduce the risk or severity of injury to the driver and front passenger in a frontal collision.
The SRS system composition which is available to NISSAN MODEL Y61 is as follows (The composition var-
ies according to the destination.):
Driver air bag module (located in the center of the steering wheel), front passenger air bag module (located
on the instrument panel on passenger side), seat belt pre-tensioner, a diagnosis sensor unit, warning lamp,
wiring harness and spiral cable.
Information necessary to service the system safely is included in theRS sectionof this Service Manual.
WARNING:
+To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag in¯ation, all maintenance must be performed
by an authorized NISSAN dealer.
+Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the RS section.
+Do 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 either just before
the harness connectors or for the complete harness are related to the SRS.
Precautions for Steering System
+Before disassembly, thoroughly clean the outside of the unit.
+Disassembly should be done in a clean work area. It is important to prevent the internal parts from
becoming contaminated by dirt or other foreign matter.
+Place disassembled parts in order, on a parts rack, for easier and proper assembly.
+Use nylon cloths or paper towels to clean the parts; common shop rags can leave lint that might
interfere with their operation.
+Before inspection or reassembly, carefully clean all parts with a general purpose, non-¯ammable
solvent.
+Before assembly, apply a coat of recommended ATF* to hydraulic parts. Vaseline may be applied
to O-rings and seals. Do not use any grease.
+Replace all gaskets, seals and O-rings. Avoid damaging O-rings, seals and gaskets during instal-
lation. Perform functional tests whenever designated.
