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.
