Front Side Air Bag Module

INFOID:0000000009635831

Front side air bag modules are built into the front seatback assem-

blies. Vehicles with side air bags are equipped with labels as shown.

Side Curtain Air Bag Module

INFOID:0000000009592939

Side curtain air bag modules are located above the vehicle headlin-

ing.Vehicles with side curtain air bags are equipped with labels on

the pillar upper finishers.

Front Seat Belt Pre-tensioner

INFOID:0000000009592873

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.

Air Bag Diagnosis Sensor Unit

INFOID:0000000009592874

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.

COMPONENT PARTS

Crash Zone Sensor

INFOID:0000000009592875

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.

Front Side Air Bag Satellite Sensor

INFOID:0000000009592940

The front side air bag satellite sensors are located on the front center

pillar LH and RH next to the seat belt pretensioners. The front side

air bag satellite sensors send signals to the air bag diagnosis sensor

unit during a side collision. These sensors may be identified by yel-

low connectors.

Rear Side Air Bag Satellite Sensor

INFOID:0000000009592941

The rear side air bag satellite sensors are located behind the lug-

gage side lower finisher LH and RH. The rear side air bag satellite

sensors send signals to the air bag diagnosis sensor unit during a

side collision. These sensors may be identified by yellow connec-

tors.

Front Door Satellite Sensor

INFOID:0000000009592942

The front door satellite sensors are located in the driver and passen-

ger doors. The front door satellite sensors send signals to the air bag

diagnosis sensor unit during a side collision. These sensors may be

identified by yellow connectors.

SRS Component Connectors

INFOID:0000000009592943

DIRECT CONNECT

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

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.

CAUTION:

• Do not pull the harness or wires when disconnecting the connector.

SYSTEM DIAGRAM

DESCRIPTION

• 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.
