1. Visually check the seat on the collision side.
2. Remove the seat on the collision side and check the following for damage and
deformities.
- Harness, connectors and terminals
- Frame and recliner (for front and rear seat), and also adjuster and slides (for front

Inspection ProcedureINFOID:0000000001396345
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.

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-13, "

SRS AIR BAG SYSTEM
FUNCTION DIAGNOSIS
SRS AIR BAG SYSTEM
SRS ConfigurationINFOID:0000000001396347
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:
AWHIA0001GB
SRS configuration Frontal collision Left side collision Right side collision
