THIS SRS AIR BAG SYSTEM HAS THE FOLLOWING FUNCTIONS
1. Detects crash and supply the energy for deploying air bag and seat belt pre-tensioner.
2. Detects electrical trouble in air bag system and seat belt pre-tensioner system, records trouble code, and
blinking air bag warning lamp.

3. Detects and records the deployment of air bag and seat belt pre-tensioner, and turns on air bag warning
lamp.
4. Indicates malfunctioning portion with blinking times of air bag warning lamp in diagnosis mode.
5. Indicates the malfunctioning record by CONSULT-III.

 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)

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.

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.
