RELEASE METHOD OF AIRBAG ACTIVATION PREVENTION MECHANISM
An airbag activation prevention mechanism is built into the connector for the squib circuit of the supplemental restraint system. When release of the airbag activation prevention mechanism is directed in the troubleshooting procedures shown in the illustrations of the connector (1), (2) and (3), 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 mechanism unless specifically directed by the troubleshooting procedure.
^ If the paper inserted is too thick the terminal and short spring may be damaged, so always use paper the same thickness as the male terminal.
