Description
The air bag deploys if the diagnosis sensor unit activates while the ignition switch is in “ON” or “START”
position.
The collision modes for which supplemental restraint systems are activated are different among the SRS
systems. For example, the driver’s air bag module and passenger’s air bag module are activated in a fron-
tal collision but not in a side collision.
SRS configurations which are activated for some collision modes are as follows;
SRS configuration
Frontal collision
Left side collision
Right side collision

●
Check diagnosis sensor unit and bracket for dents, cracks or
deformities.
●
Check connectors for damage, and terminals for deformities.
(2) Air bag module and steering wheel
●
Remove air bag module from steering wheel, instrument
panel or seat back. Check harness cover and connectors for
damage, terminals for deformities, and harness for binding.
●
Install driver’s air bag module to steering wheel to check fit
or alignment with the wheel.

●
Check harness cover and connectors for damage, terminals
for deformities, and harness for binding.
●
Check belts for damage and anchors for loose mounting.
●
Check retractor for smooth operation.
