Diagnosis Description
INFOID:0000000003367332
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 harness
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-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, Frequencies.
• WHERE. . Road conditions.
• HOW. . Operating conditions, Symptoms.
Preliminary Check.
Check that the following parts are in good order.
• Battery (Refer to
).
• System component-to-harness connections.
HOW TO ERASE SELF-DIAGNOSTIC RESULTS (With CONSULT-III)
• “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 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.
HOW TO ERASE SELF-DIAGNOSTIC RESULTS (Without CONSULT-III)
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.

DIAGNOSTIC PROCEDURE (With CONSULT-III)
CONSULT-III Function
INFOID:0000000003367333
DIAGNOSIS MODE FOR CONSULT-III
• “SELF-DIAG [CURRENT]”
A 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 will be displayed on CONSULT-III screen, as shown. 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 confirming this classification number on CONSULT-III screen.
After repair, check that the discriminated number of air bag diagnosis sensor unit installed to vehicle are the
same. Refer to
SR-19, "Removal and Installation"
.
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.
