Trouble Diagnosis with CONSULT-III

INFOID:0000000001277708

DIAGNOSTIC PROCEDURE 4

Check SRS Repair History

CONSIDER POSSIBILITY THAT SELF-DIAGNOSTIC RESULT WAS NOT ERASED AFTER REPAIR

Check repair history of the SRS.

Have any previous repairs been made to the SRS?

Yes

>> Self-diagnostic result “SELF-DIAG [PAST]” (previously stored in the memory) might not be erased

after repair. Go to "DIAGNOSTIC PROCEDURE 3". Refer to

SRC-15, "Self-Diagnosis Function

(Without CONSULT-III)"

>> Go to "DIAGNOSTIC PROCEDURE 2". Refer to

SRC-13, "SRS Operation Check"

SRS AIR BAG SYSTEM

FUNCTION DIAGNOSIS

SRS AIR BAG SYSTEM

SRS Configuration

INFOID:0000000001277709

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 sys-
tems. For example, the driver air bag module, front passenger air bag module and front seat belt pre-tension-
ers are activated in a frontal collision but not in a side collision.
SRS configurations for some collision modes are as follows:

SRS AIR BAG SYSTEM

Front Passenger Air Bag Module

INFOID:0000000001277783

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:0000000001277713

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:0000000001277714

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:0000000001277784

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.
