Occupant Classification System (OCS) NHS0008W
The occupant classification system identifies different size occupants, out of position occupants, and detects if
child seat is present in the front passenger seat. The occupant classification system receives inputs from the
occupant classification sensor (located inside the passenger seat cushion assembly) and belt tension sensor
(part of the passenger front seat belt assembly and located at the belt anchor location). Depending on classifi-
cation of passenger, the occupant classification system sends a signal to the diagnosis sensor unit. The diag-
nosis sensor unit uses this signal to determine full, partial, or non deployment of passenger front air bag in the
event of a collision. Depending on the signal received, the diagnosis sensor unit can disable the passenger
front air bag completely.
NOTE:
In case of customer concern, CONSULT-ll can be used to confirm the passenger air bag status (readiness).

Trouble Diagnosis IntroductionNHS00090
CAUTION:

Do not use electrical test equipment on any circuit related to the SRS unless instructed in this Ser-
vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or har-
ness connectors.

Do not 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 “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 DIAGNOSIS 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.

CONSULT-II FunctionNHS00094
DIAGNOSIS MODE FOR CONSULT-II

“SELF-DIAG [CURRENT]”
A current self-diagnosis results (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.

“SELF-DIAG [PAST]”
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.

“TROUBLE DIAG RECORD”
With TROUBLE DIAG RECORD, diagnosis results previously erased by a reset operation can be dis-
played on the CONSULT-II screen.

“ECU DISCRIMINATED NO.”
The diagnosis sensor unit for each vehicle model is assigned
with its own, individual classification number. This number will
be displayed on the CONSULT-II screen, as shown. 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.
After repair, make sure the discriminated number of diagnosis
sensor unit installed to vehicle are same. Refer to SRS-52,
"ECU DISCRIMINATED NO." .

PASSENGER AIR BAG
The STATUS (Readiness) of the front passenger air bag module is displayed.The STATUS displayed
(ON/OFF) depends on the signals supplied to the occupant classification system control module and
air bag diagnosis sensor unit. Refer to SRS-7, "
Occupant Classification System (OCS)" for more infoma-
tion.
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, then diagnosis mode automatically changes to User mode.

HOW TO ERASE SELF-DIAGNOSTIC RESULTS

“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]”.

“SELF-DIAG [PAST]”
Return to the “SELF-DIAG [CURRENT]” CONSULT-II screen by touching “BACK” key of CONSULT-II and
select “SELF-DIAG [CURRENT]” in SELECT DIAG MODE. Touch “ERASE” in “SELF-DIAG [CURRENT]”
mode.
NOTE:
If the memory of the malfunction in “SELF-DIAG [PAST]” is not erased, the User mode shows the system
malfunction by the operation of the warning lamp even if the malfunction is repaired completely.

“TROUBLE DIAG RECORD”
The memory of “TROUBLE DIAG RECORD” cannot be erased.
Self-Diagnosis Function (Without CONSULT-II)NHS00095

The reading of these results is accomplished “User mode” and “Diagnosis mode”.

After a malfunction is repaired, turn ignition switch ON. Diagnosis mode returns to the User mode. At that
time, the self-diagnosis result is cleared.
HOW TO CHANGE SELF-DIAGNOSIS MODE WITHOUT CONSULT-II
HOW TO ERASE SELF-DIAGNOSTIC RESULTS
After a malfunction is repaired, turn the ignition switch OFF for at least one second, then back ON. Diagnosis
mode returns to the User mode. At that time, the self-diagnosis result is cleared.

charge or replace the battery. Then go to SRS-27, "
DIAGNOS-
TIC PROCEDURE 3" . If the battery voltage is OK, go to SRS-
29, "DIAGNOSTIC PROCEDURE 4 (CONTINUED FROM
DIAGNOSTIC PROCEDURE 2)" to diagnose the following
cases:
