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.
I Do not attempt to repair, splice or modify the SRS wiring harness. If the harness is damaged,
replace it with a new one.
I Keep 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
I ªSELF-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.
I 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.
I ªTROUBLE DIAG RECORDº
With TROUBLE DIAG RECORD, diagnosis results previously erased by a reset operation can be displayed
on the CONSULT-II screen.
I ªECU 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

After selecting ªAIR BAGº on the ªSELECT SYSTEMº screen, User mode automatically changes to Diagno-
sis mode.
From Diagnosis Mode to User Mode
To return to User mode from Diagnosis mode, touch ªBACKº key of CONSULT-II until ªSELECT SYSTEMº
appears, Diagnosis mode automatically changes to User mode.
HOW TO CHANGE SELF-DIAGNOSIS MODE WITHOUT CONSULT-II
From User Mode to Diagnosis Mode
When a malfunction is detected, activate the Diagnosis mode by turning the ignition switch as follows:
1) Turn ignition switch ªONº.
2) After ªAIR BAGº warning lamp lights for 7 seconds, turn ignition switch ªOFFº within 1 second.
3) Wait more than 3 seconds.
4) Repeat steps 1 to 3 three times.
5) Turn ignition switch ªONº.
SRS will not enter Diagnosis mode if no malfunction is detected.
From Diagnosis Mode to User Mode
After a malfunction is repaired, switch the ignition ªOFFº for at least one second, then back ªONº. Diagnosis
mode is returned to User mode.
When a malfunction is detected, switch from Diagnosis mode to User mode by turning the ignition switch as
follows:
1) Turn ignition switch ªONº.
2) After ªAIR BAGº warning lamp lights for 7 seconds, turn ignition switch ªOFFº within 1 second.
3) Wait more than 3 seconds.

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.
I 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 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.
I ªTROUBLE 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.
