Inspection and Repair (with SRS air
bag)
The inflator module consists of a cover, air bag, inflator,
and retainer. Inspect the inflator module mainly for the
following:
・ Check for holes, cracks, severe blemishes and
deformation on the cover.
・ Check that the retainer is not deformed.
・ Check for defects such as damage and breakage in
the lead wire for the igniter.
If an abnormality is found as a result of the inspection,
replace the inflator module with a new one.

Installation
1. Support the inflator module and carefully connect the
SRS connector (1) and horn lead (2) (with SRS ai
r
bag).
