Inspection Procedure

INFOID:0000000004215154

INTERMITTENT TROUBLE

An intermittent incident may have occured in the past but is not being detected currently.  This DTC will not be

detected on SELF DIAG [CURRENT], but may be viewed on SELF DIAG [PAST] using CONSULT-III.

Trouble Diagnosis with CONSULT-III

INFOID:0000000004215155

DIAGNOSTIC PROCEDURE 4

Check SRS Repair History

1.

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. Proceed to "DIAGNOSTIC PROCEDURE 3".  Refer to 

SRC-14, "Self-Diagnosis Func-

tion (Without CONSULT-III)"

.

NO

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

SRC-12, "SRS Operation Check"

.

SRS AIR BAG SYSTEM

FUNCTION DIAGNOSIS

SRS AIR BAG SYSTEM

SRS Configuration

INFOID:0000000004215156

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:

< FUNCTION DIAGNOSIS >

SRS AIR BAG SYSTEM

Front Passenger Air Bag Module

INFOID:0000000004215159

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:0000000004215160

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:0000000004215161

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:0000000004215162

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.
