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.

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-

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.
