DIAGNOSTIC PROCEDURE
1.CHECK DIFFERENTIAL SOLENOID SIGNAL
With CONSULT-II
1. Start engine.
2. Select “DATA MONITOR” mode for “DIFF LOCK” with CONSULT-II.
3. Read out ON/OFF switching action of “RELAY ON”, “RELAY
MTR”, “SOL MTR”.

OPERATION PROCEDURE OF CURRENT MEASUREMENT PROBE FOR CONSULT-II
For details, refer to the supplied “CONSULT-II Current Probe Operation Manual”.
1. Turn current probe power supply OFF and connect to CONSULT-II. (Red: CH1, Black: Ground)
2. Touch “SUB MODE”.
3. Touch “Extending Measurement Mode” on “SUB MODE” screen.
4. CAUTION is displayed, touch “OK”.
5. Set current probe range switch at the range to measure, turn
current probe power supply ON. When measuring dark current,
set 4A range. (Check that POWER indicator turns on. Refer to
CONSULT-II Current Probe Operation Manual.)
6. Touch the same measuring range at CONSULT-II.
NOTE:
If current probe measuring range is different from CONSULT-II
measuring range, incorrect value is displayed.
7. Adjust 0 point of current probe or CONSULT-II. (Do not clamp
anything to probe.)
NOTE:
If 0 point is dislocated greatly, adjust at current probe side gen-
erally.
8. Align current direction mark, clamp harness, and measure cur-
rent. If current direction is incorrect, it is displayed negative
value.
NOTE:
lWhen current is measured, close probe joint securely.
lIf multiple harnesses are clamped, measurement cannot be
performed. Always clamp only one.

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.

HOW TO CHANGE SELF-DIAGNOSIS MODE WITH CONSULT-II
From User Mode to Diagnosis Mode
After selecting “AIR BAG” on the “SELECT SYSTEM” screen, User mode automatically changes to Diagnosis
mode.
From Diagnosis Mode to User Mode
To return to User mode from Diagnosis mode, touch “BACK” key of CONSULT-II until “SELECT SYSTEM”
appears, Diagnosis mode automatically changes to User mode.
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
curtain air bags) and A939 (for models without
side and side front curtain air bags).

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.
