Operation 2.
When air bag deployment signal (OFF→ON) is input 7 seconds (T4) after IGN ON
Signal from unlock relay is output for 5 seconds (T3) after 40 ms (T2)
When turning IGN OFF during 5 seconds (T3) of unlock relay signal output
Signal from unlock relay is input for the rest of the time

Operation 1.
Air bag deployment signal is not input for initial 7 seconds (T4) after IGN ON
A.
The room lamp comes on when the air bag deployment signal is input except when the room lamp
switch is turned off.
The hazard warning lamp flashes when the air bag deployment signal is input.
Resetting the auto door unlock function turns off the battery (cutting off BCM power).

(2) BCM control when air bag deployment signal is input
The UNLOCK by the air bag deployment signal takes priority over the LOCK/UNLOCK control from
other functions.
The LOCK/UNLOCK requests from other functions during or after the UNLOCK output by the air
bag signal are ignored. However, the LOCK control is carried out when the ignition switch is turned
to the "OFF" position.
The same request during the LOCK/UNLOCK output is ignored. However, the UNLOCK by the air
bag deployment signal or operation by the smart key is carried out.
When LOCK and UNLOCK outputs occur at the same time, the LOCK output is carried out and
UNLOCK is ignored.

4. AIR BAG SYSTEM SELF DIAGNOSIS
1) Air Bag Unit (SDM) Self Diagnosis
The air bag unit monitors the internal/external devices of the air bag system including battery voltage,
limits certain functions of the air bag, and turns on the air bag warning lamp on the instrument cluster
according to the conditions.
Conditions for detecting and clearing faults
The time for detecting errors and clearing the errors is as follows:

Air bag warning lamp
2) Air Bag Warning Lamp
The air bag unit turns on the air bag warning lamp on the instrument cluster for 6 seconds after IGN ON
while performing self diagnosis for the air bag system. If no fault is found in the system, it turns off the
warning lamp. After this, the unit monitors the system regularly, and notifies the driver by turning on the
air bag warning lamp when a fault is found in the system.
System normal
Comes on for 6 seconds after IGN ON and then goes out.
▶
The air bag warning lamp comes on when:
*
diagnosis is performed for the inside/external devices of
the system when the ignition is turned on
the air bag system is malfunctioning
the air bag unit and a diagnostic equipment communicate
each other

System malfunctioning
Comes on for 6 seconds after IGN ON and goes out for 1 second, and then remains on.
▶
(2) Air bag warning lamp operation during driving
The air bag warning lamp comes on when the air bag unit (SDM) detects a system malfunction. The
warning lamp goes out when the malfunction disappears.
