Air bag diagnosis sensor units are prepared for operation while the ignition switch is in the ON or START
position.
The operation of Supplemental Restraint System is different from collision modes application. For example,
the driver air bag module and front passenger air bag module are activated in a frontal collision but not in a
side collision.
SRS configurations which are activated for some collision modes are as follows.
1. Front passenger air bag module M62 2. Driver air bag module M350 3. Conbination switch (Spiral cable)

Diagnosis DescriptionINFOID:0000000003813934
CAUTION:
• Never 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 harness
connectors.
Never 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-III.
The user mode is exclusively prepared for the customer (driver). This mode warns the driver of a system
malfunction 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-III 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.
Information from Customer.
WHAT..... Vehicle model.
WHEN..... Date, Frequency.
WHERE..... Road conditions.
HOW..... Operating conditions, Symptoms.
Preliminary Check.
Check that the following parts are in good order.
Battery (Refer to PG-3, "
How to Handle Battery").
Fuse (Refer to PG-82, "
Fuse").
System component-to-harness connections.
Air Bag Warning Lamp DiagnosisINFOID:0000000003843289
SELF-DIAGNOSIS FUNCTION
The reading of these results is accomplished by “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.

After a malfunction is repaired, turn the ignition switch OFF for at least one second, then turn ignition switch
ON. Diagnosis mode returns to the user mode. At that time the self-diagnosis result is cleared.
CONSULT-III FunctionINFOID:0000000003813935
HOW TO CHANGE SELF-DIAGNOSIS MODE WITH CONSULT-III
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-III until “SELECT SYSTEM”
appears, then Diagnosis mode automatically changes to User mode.
DIAGNOSIS MODE FOR CONSULT-III
“SELF-DIAG [CURRENT]”
Current self-diagnosis results (also indicated with the number of air bag warning lamp blinks in Diagnosis
mode) are displayed on CONSULT-III 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 CONSULT-III 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 displayed
on CONSULT-III screen.
“DISCRIMINATED NO.”
The air bag diagnosis sensor unit for each vehicle model has its own individual classification number. This
number is displayed on CONSULT-III screen. When replacing 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 con-
firming this classification number on CONSULT-III screen.
After repair, check that the discriminated number of air bag diagnosis sensor unit installed to vehicle is the
same. Refer to SR-22, "
Exploded View".
HOW TO ERASE SELF-DIAGNOSTIC RESULTS
“SELF-DIAG [CURRENT]”
A current self-diagnosis result is displayed on CONSULT-III screen in real time.
After the malfunction is repaired completely, no malfunction is detected on “SELF-DIAG [CURRENT]”.
“SELF-DIAG [PAST]”
Return to “SELF-DIAG [CURRENT]” CONSULT-III screen by touching “BACK” key of CONSULT-III 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 illuminating the warning lamp even if the malfunction is repaired completely.
“TROUBLE DIAG RECORD”
The memory of “TROUBLE DIAG RECORD” cannot be erased.
