Trouble Diagnosis IntroductionEHS001XG
CAUTION:
lDo not use electrical test equipment on any circuit related to the SRS unless instructed to do so in
this Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harness con-
nectors.
lDo not attempt to repair, splice or modify SRS wiring harnesses. If a harness is damaged, replace
it with a new one.
lKeep ground connections clean.
DIAGNOSIS FUNCTION
The SRS self-diagnosis results can be read by using “AIR BAG” warning lamp and/or CONSULT-II.
The User mode is exclusively prepared for the customer (driver). This mode warns the driver of a system mal-
function through the operation of the “AIR BAG” warning lamp.
The Diagnosis mode allows the technician to locate and inspect the malfunctioning part.
The mode applications for the “AIR BAG” warning lamp and CONSULT-II are as follows:
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.

AIR BAG diagnostic mode Description
SELF-DIAG [CURRENT]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 requir-
ing repairs.
SELF-DIAG [PAST]Diagnosis results previously stored in the memory are displayed on the CONSULT-II screen. The
stored results will remain until memory erasing is executed.
TROUBLE DIAG RECORDWith TROUBLE DIAG RECORD, diagnosis results previously erased by a reset operation can be dis-
played on the CONSULT-II screen.
ECU DISCRIMINATED NO.The air bag diagnosis sensor unit for each vehicle
model is assigned with its own, individual classifi-
cation number. This number will be displayed on
the CONSULT-II screen, as shown. When replac-
ing the air bag 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 CON-
SULT-II screen.
For NISSAN MODEL R51, the air bag diagnosis
sensor unit discriminated numbers assigned
are A937 (for models with side and side front

HOW TO ERASE SELF-DIAGNOSIS RESULTS
l“SELF-DIAG [CURRENT]”
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 “SELF-DIAG [CURRENT]”.
l“SELF-DIAG [PAST]”
Return to the “SELF-DIAG [CURRENT]” CONSULT-II screen by
touching “BACK” key of CONSULT-II and select “SELF-DIAG
[PAST]” in SELECT DIAG MODE. Touch “ERASE” in “SELF-
DIAG [PAST]” mode.
NOTE:
If the memory of the malfunction in “SELF-DIAG [PAST]” is
not erased, the User mode will continue to show the system
malfunction by the operation of the warning lamp even if
the malfunction is repaired completely.
l“TROUBLE DIAG RECORD”
The memory of “TROUBLE DIAG RECORD” cannot be erased.
Self-Diagnosis Function (Without CONSULT-II)EHS001XM
lThe reading of these results is accomplished using one of two modes — “User mode” and “Diagnosis
mode”.
lAfter a malfunction is repaired, turn the ignition switch OFF for at least one second, then back ON. Diag-
nosis mode returns to the User mode. At that time, the self-diagnostic result is cleared.

TROUBLE DIAGNOSIS
NOTE:
Follow the procedures in numerical order when repairing malfunctioning parts. Confirm whether malfunction is
eliminated using air bag warning lamp or CONSULT-II each time repair is finished. If malfunction is still
observed, proceed to the next step. When malfunction is eliminated, further repair work is not required.
DIAGNOSTIC PROCEDURE 3
Final Check of SRS Using CONSULT-II—Diagnosis Mode
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunction might be detected
in self-diagnosis depending on control unit which carry out CAN communication.
1. After repairing SRS, connect both battery cables.
2. Connect CONSULT-II and CONSULT-II CONVERTER to data
link connector.
3. Turn ignition switch ON.
4. Touch “START (NISSAN BASED VHCL)”.
5. Touch “AIR BAG”.
If "AIR BAG" is not indicated, refer toGI-50, "
