DescriptionINFOID:0000000012430604
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 identifi ed by yellow and/or orange harnesses or harness
connectors.
• Never repair, splice or modify the SRS wiring harn ess. If the harness is damaged, replace it with a
new one.
• Keep ground portion clean.
DIAGNOSIS FUNCTION
• The SRS self-diagnostic results can be read with air bag warning lamp and/or CONSULT.
• 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 are as per the following items.

ON-BOARD DIAGNOSIS
There are two self diagnosis functions with air bag warning lamp per the following items.
•USER MODE
• DIAGNOSIS MODE
METHOD OF STARTING
• Diagnosis mode changes from user mode to diagnosis mode when changing operation is performed.
• In user mode, when SRS air bag warning lamp is not turning ON, changing to diagnosis mode by ignition
switch operation is not possible.
• In diagnosis mode, when repair is complete and system is normal, the mode changes to user mode when
ignition switch is turned from OFF to ON.
Procedure to Change Diagnosis Mode
1. Turn ignition switch from OFF to ON.
2. SRS air bag lamp turns ON for 7 seconds and turns OFF, then turn ignition switch OFF within 2 seconds after the lamp turns OFF.
NOTE:
When in Diagnosis Mode, the air bag warning lamp may illuminate for more than 7 seconds after the igni-
tion switch is turned ON. If this is the case, the i gnition switch must still be cycled OFF after 7 seconds.
3. After turning ignition switch OFF, wait for 3 seconds or more.
4. Repeat operation 1 to 3 for 2 times so that operation 1 to 3 is repeated for 3 times in total.
5. Turn ignition switch from OFF to ON. Diagnosis mode changes.
USER MODE
In USER MODE, air bag warning lamp on combination meter turns ON when a malfunction is detected and
warns the customer (driver).
How to Read Air Bag Warning Lamp
1. Turn the ignition switch from OFF to ON, and check that the air bag warning lamp turns ON.
2. Compare the air bag warning lamp operation pattern with the examples.
