SRS CONTROL SYSTEM 9C-7
SRS airbag assembly
SRS airbag consists of the airbag and the inflator (a can
with gas generator agent and a ignition device). SRS
control unit sends current to the deployment circuit in the
event of front collision over certain degree of impact.
Passage of electric current in the inflator will light the
gas generator agent in the SRS airbag.
Gas generated in the reaction rapidly inflate the airbag.
A shorting clip is equipped to the SRS airbag. Upon re-
moval of SRS airbag connector, the shorting clip shorts
the SRS airbag circuit.
The circuit to SRS airbag is shorted in this manner. This
prevents unnecessary deployment of SRS airbag when
servicing SRS airbag assembly, steering column or oth-
er SRS system parts.
