SRS AIR BAG SYSTEM

Front Passenger Air Bag Module

INFOID:0000000009466477

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:0000000009466478

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:0000000009466479

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

INFOID:0000000009466480

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.

OCCUPANT CLASSIFICATION SYSTEM

OCCUPANT CLASSIFICATION SYSTEM

INFOID:0000000009466482

Occupant Classification System (OCS)

INFOID:0000000009466483

The occupant classification system (OCS) identifies if a child or child

seat is present in the front passenger seat. The OCS receives inputs

from the occupant classification sensor mat (1) which is located

inside the passenger seat cushion assembly. Depending on classifi-

cation of the passenger, the OCS control unit (2) 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 deter-

mine deployment or non-deployment of the front passenger air bag

module in the event of a collision. Depending on the signals

received, the air bag diagnosis sensor unit can disable the front pas-

senger air bag module completely.

NOTE:

In case of customer concern, CONSULT can be used to confirm the front passenger air bag status (readi-

ness).
