Driver Air Bag Module

INFOID:0000000009515825

The driver air bag module is single stage and located in the steering

wheel assembly. It operates with the SRS system in a frontal colli-

sion exceeding a specified level.

Front Passenger Air Bag Module

INFOID:0000000009515826

The front passenger air bag module is single stage and is located

behind the instrument panel assembly. It operates with the SRS sys-

tem in a frontal collision exceeding a specified level. 

Front Seat Belt Pre-tensioner

INFOID:0000000009515827

The seat belt pre-tensioner system with load limiter is installed for

both the driver's seat and the front passenger's seat. It operates

simultaneously with the SRS air bag system in the event of a frontal

collision with an impact exceeding a specified level.

When the frontal collision with an impact exceeding a specified level

occurs, seat belt slack resulting from clothing or other factors is

immediately taken up by the belt pre-tensioner. Vehicle passengers

are securely restrained.

When passengers in a vehicle are thrown forward in a collision and

the restraining force of the seat belt exceeds a specified level, the

load limiter permits the specified extension of the seat belt by the

twisting of the ELR shaft, and a relaxation of the chest-area seat belt

web tension while maintaining force.

No.

Component

Function

1.

Combination switch (spiral cable)

The spiral cable provides a rotating physical connection to the drivers 
air bag module.

2.

Driver air bag module

Refer to 

SRC-5, "Driver Air Bag Module"

.

3.

Front passenger air bag module 

Refer to 

SRC-5, "Front Passenger Air Bag Module"

.

4.

Seat belt buckle switch LH

The driver seat belt buckle switch provides the seat belt buckle signal 
to the air bag diagnosis sensor unit and the combination meter.

5.

Air bag diagnosis sensor unit

Refer to 

SRC-6, "Air Bag Diagnosis Sensor Unit"

.

6.

Front seat belt pre-tensioner LH (RH similar)

Refer to 

SRC-5, "Front Seat Belt Pre-tensioner"

.

7.

Combination meter (air bag warning lamp)

The combination meter displays the air bag warning lamp and the 
seat belt warning lamp. The air bag warning lamp is used for diagno-
sis in User Mode and may be used to display diagnostic trouble 
codes without the use of the CONSULT.

8.

Crash zone sensor

Refer to 

SRC-6, "Crash Zone Sensor"

COMPONENT PARTS

Air Bag Diagnosis Sensor Unit

INFOID:0000000009515828

The air bag diagnosis sensor unit is located under the center con-

sole assembly. The air bag diagnosis sensor unit receives signals

from multiple SRS sensors and controls the deployment of the air

bags. The deployment of the air bags depends on the type and

severity of the collision. The air bag diagnosis sensor unit has self-

diagnosis capability through the use of the CONSULT as well as

flash codes displayed by the air bag warning lamp.

Crash Zone Sensor

INFOID:0000000009515829

The crash zone sensor is located in front of the radiator. The crash

zone sensor sends signals to the air bag diagnosis sensor unit dur-

ing a frontal collision. This sensor may be identified by a yellow con-

nector.

SRS Component Connectors

INFOID:0000000009641655

DIRECT CONNECT

The following SRS components use direct-connect style harness connectors.

• Driver front air bag module

• Passenger front air bag module

• LH side curtain air bag module

• RH side curtain air bag module

• Front LH seat belt pre-tensioner

• Front RH seat belt pre-tensioner

Always pull up to release locking tab prior to removing connector from SRS component.

Always push down to lock locking tab after installing connector to

SRS component. When locked, the locking tab is level with the con-

nector housing.

SLIDE DOUBLE LOCKING

• A new style slide double locking type connector is used on certain systems and components, especially

those related to airbag control systems.

• The slide double locking type connectors help prevent incomplete locking and accidental looseness or dis-

connection.

• The slide double locking type connectors are disconnected by pushing or pulling the slider. Refer to the fig-

ure below.

SRS AIR BAG SYSTEM : System Description

INFOID:0000000009541305

• The air bag deploys if the air bag diagnosis sensor unit is activated while the ignition switch is in the ON or

START position.

• The collision modes for which supplemental restraint systems are activated are different among the SRS

systems. For example, the driver air bag module, front passenger air bag module and front seat belt pre-ten-

sioners are activated in a frontal collision but not in a side collision.
