SRS AIR BAG SYSTEM

Front Passenger Air Bag Module

INFOID:0000000009882862

The front passenger air bag module is located behind the instrument

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

sion exceeding a specified level.  Refer to 

SRC-10, "Occupant Clas-

sification System (OCS)"

   for more information.

Front Side Air Bag

INFOID:0000000009882863

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

INFOID:0000000009882864

Side curtain air bag modules are located above the vehicle headlining.

Vehicles with side curtain air bags are equipped with labels as

shown.

Front Seat Belt Pre-tensioner with Load Limiter

INFOID:0000000009882865

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 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.

Direct-connect SRS Component Connectors

INFOID:0000000009882866

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.

CAUTION:

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

OCCUPANT CLASSIFICATION SYSTEM

OCCUPANT CLASSIFICATION SYSTEM

INFOID:0000000009882867

Occupant Classification System (OCS)

INFOID:0000000009882868

The occupant classification system (OCS) identifies different size occupants, out of position occupants, and

detects if child seat is present in the front passenger seat. The OCS receives inputs from the occupant classi-

fication sensor (located inside the passenger seat cushion assembly) and belt tension sensor (part of the pas-

senger front seat belt assembly and located at the belt anchor location). Depending on classification of the

passenger, the OCS sends a signal to the air bag diagnosis sensor unit. The air bag diagnosis sensor unit

uses this signal and the seat belt buckle switch RH signal to determine deployment or non deployment of the

passenger front air bag in the event of a collision. Depending on the signals received, the air bag diagnosis

sensor unit can disable the passenger front air bag completely.

NOTE:

In case of customer concern, CONSULT can be used to confirm the passenger air bag status (readiness).
