Seat belt pre-tensioner LH/RH

• Receives signal from air bag diagnosis sensor unit and deploys seat belt pre-ten-

sioner and lap pre-tensioner.

• In the case of a frontal collision or side collision that exceeds specified impact level, 

the air bag diagnosis sensor unit detects the deceleration caused by collision. It re-
strains the passenger with seat belt easing the stress on passengers chest with 
load limiter.

Side air bag module LH/RH

• Receives signal from air bag diagnosis sensor unit and deploys air bag.
• In case of side collision where acceleration is more than the specified level, the ig-

nition materials are ignited by electric ignition system. The system burns the gas 
generating materials resulting in a chemical reaction. This generates hot gases that 
flow into the air bag through a filter and expand the bag.

System Description

INFOID:0000000008461769

Supplemental Restraint System (SRS) activates air bag module and seat belt pre-tensioner when it detects a
frontal collision or a side collision that is more than the specified limit.
Together with other safety devices, it reduces the impact that occupant receives when vehicle collision occurs.
Air bag diagnosis sensor unit supplies power supply to air bag module and pre-tensioner seat belt when decel-
eration that is more than the specified limit is detected by G sensor in air bag diagnosis sensor unit, crash
zone sensor, satellite sensor, or front door satellite sensor.

Air bag module is composed of electric igniter (squib), filter, pyrotechnic material, and gas generating material.
When air bag module receives a signal from air bag diagnosis sensor unit, air bag module ignites pyrotechnic
material using electric igniter (squib) so that gas generating material generates high temperature nitrogen gas.
The gas through filter activates air bag. At the same time, pre-tensioner seat belt receives power supply from
air bag diagnosis sensor unit, gas generator is activated, and then gas is generated.
Balls in pipe are moved according to generated gas pressure and strike pinion gear on ELR shaft.
ELR shaft rotates and retracts seat belt.

AIR BAG DIAGNOSIS SENSOR UNIT FUNCTIONS

Air bag diagnosis sensor unit has the following functions.
• Detects a collision and supplies the energy for deploying air bag and seat belt pre-tensioner.
• Detects and records electrical malfunction in air bag system and seat belt pre-tensioner system, and blinking

air bag warning lamp.

• Detects and records the deployment of air bag and seat belt pre-tensioner, and turns ON air bag warning

lamp.

• Indicates malfunctioning portion via the number of blinks from the air bag warning lamp in the diagnosis

mode.

• Indicates the malfunction record via CONSULT.
• Suppresses the deployment of passenger air bag when passenger seat is empty or occupied by child or

child-seat.

• When passenger seat is occupied by child or child seat, turns ON passenger air bag OFF indicator. 
• When judges that passenger seat is occupied by a adult or a child and passenger seat belt is not fasten,

turns ON seat belt warning lamp. Further information for the seat belt warning system.

COLLISION MODES

The operation of SRS is different depending on the collision modes applications. For example, the driver air
bag module, passenger air bag module, and seat belt pre-tensioner are activated in a frontal collision or side
collision.
SRS configurations that are activated for the following collision modes.

OCCUPANT CLASSIFICATION SYSTEM

Occupant Classification System has the following functions.
• Suppresses the deployment of passenger air bag when passenger seat is empty, or when occupied by child

and child-seat.

• Turns on front passenger air bag OFF indicator when passenger seat is occupied by child-seat and child.
• Indicates malfunction portion via the number of blinks from the air bag warning lamp in the diagnosis mode.
• Indicates the malfunctioning record via CONSULT.
NOTE:
Operation of air bag diagnosis sensor unit when air bag diagnosis sensor unit receives information from Occu-
pant Classification System.

DIAGNOSIS SYSTEM (AIR BAG)

Description

INFOID:0000000008461770

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-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 Function

INFOID:0000000008461771

ON-BOARD DIAGNOSIS 

There are two self diagnosis functions with air bag warning lamp as 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 blinking, 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 second and turns OFF, then turn ignition switch OFF within 1second after
the lamp turns OFF.

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 3times 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 blinks 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 blinks.

2.

Compare the air bag warning lamp blinking pattern with the examples.

INFOID:0000000008461772

APPLICATION ITEM

CONSULT performs the following functions.

CAUSE OF WARNING LAMP ILLUMINATION

The SRS air bag warning lamp blinks when the ignition voltage is a voltage value (9V or less, or 16 V or more)
at which the SRS air bag cannot operate normally.After blinking, if the ignition voltage returns to normal, SRS
air bag warning lamp turns OFF.DTC memory is not performed while the abnormal ignition voltage is
detected.The mode cannot be switched to trouble diagnosis mode when the ignition switch is operated.“No
DTC” is displayed when checking “Self-diagnosis result” using CONSULT.
NOTE:
• SRS air bag warning may blink when the condition is out of detection area* of the satellite sensor in door.

The system is normal if SRS air bag warning lamp turns OFF after the condition returns within detection area
of the satellite sensor in door.

• SRS air bag warning lamp blinks when the zero point reset is incomplete after replacing the occupant detec-

tion system control unit.(SRS air bag warning lamp turns OFF after the zero point reset is complete.)

• *: Pressure inside of door is excessively low and air bag system cannot be operated normally (example: alti-

tude is approximately 4,000 m or more).
