Trouble Diagnoses Introduction
CAUTION:
+Do not use electrical test equipment to check SRS harness connectors unless instructed to in
this Service Manual. SRS wiring harnesses can be identified by yellow harness protector or yel-
low insulation tape before the harness connectors.
+Do not attempt to repair, splice or modify the SRS wiring harness. If the harness is damaged,
replace it with a new one.
+Keep ground portion clean.
DIAGNOSIS FUNCTION
The SRS self-diagnosis results can be read by using ªAIR BAGº warning lamp, ªSEAT BELTº warning lamp
(Models except for Europe) and/or CONSULT-II. The reading 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 and/or ªSEAT BELTº warning lamp (Mod-
els except for Europe).
The Diagnosis mode allows the technician to locate and inspect the malfunctioning part.
The mode applications for the ªAIR BAGº warning lamp, ªSEAT BELTº warning lamp (Models except for
Europe) and CONSULT-II are as follows:
User mode Diagnosis mode Display type
ªAIR BAGº warning lamp X X ON-OFF operation
ªSEAT BELTº warning lamp
(Models except for Europe)X Ð ON-OFF operation
CONSULT-II Ð X Monitoring
DIAGNOSIS MODE FOR CONSULT-II
+ªSELF-DIAG [CURRENT]º
A current Self-diagnosis result (also indicated by the 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.
+ªSELF-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.
+ªTROUBLE DIAG RECORDº
With TROUBLE DIAG RECORD, diagnosis results previously erased by a reset operation can be dis-
played on the CONSULT-II screen.
+ªECU DISCRIMINATED NO.º
The diagnosis sensor unit for each vehicle model is assigned with its own, individual classification num-
ber. This number will be displayed on the CONSULT-II screen, as shown at left. 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. The
diagnosis sensor unit classification number varies depending on SRS configuration.
For NISSAN MODEL Y61, the diagnosis sensor unit classification numbers are as follows.
MODEL ECU DISCRIMINATED NO.
WagonModel with dual air bags and side air bag 5A0F
Model with dual air bags 5A11
Model with single air bag 5A13
HardtopModel with side air bag 5A15
Model with dual air bags 5A17
Model with single air bag 5A19

HOW TO ERASE SELF-DIAGNOSIS RESULTS
With CONSULT-II
+ªSELF-DIAG [CURRENT]º
A current Self-diagnosis result is displayed on the CONSULT-II screen in real time. After the malfunc-
tion is repaired completely, no malfunction is detected on ªSELF-DIAG [CURRENT]º.
+ªSELF-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 ªSELECT DIAG MODEº. 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 system malfunction by
the operation of the warning lamp even if the malfunction is
repaired completely.
+ªTROUBLE DIAG RECORDº
The memory of ªTROUBLE DIAG RECORDº cannot be erased.
Without CONSULT-II
After a malfunction is repaired, return Diagnosis mode to User mode by switching the ignition ªOFFº for at
least 1 second, then back ªONº. At that time, the self-diagnostic result 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 malfunction. It is important to fully understand the symp-
toms or conditions for a customer complaint.
