7. RELEASE METHOD OF AIRBAG ACTIVATION PRE-
VENTION MECHANISM
An airbag activation prevention mechanism is built into the con-
nector for the squib circuit of the SRS.
When release of the airbag activation prevention mechanism is
directed in the troubleshooting procedure, as shown in the il-
lustration of the connectors on the next pages, insert paper
which is the same thickness as the male terminal, between the
terminal and the short spring.
CAUTION:
Never release the airbag activation prevention mechanism
on the steering wheel pad connector.
NOTICE:
Do not release the airbag activation prevention mech-
anism unless specifically directed by the trouble-
shooting procedure.
If the inserted paper is too thick the terminal and short
spring may be damaged, so always use paper with
the same thickness as the male terminal.
