RELEASE METHOD OF ACTIVATION PREVENTION MECHANISM
The activation prevention mechanism is built into the connector for the squib circuit of the SRS.
As explained in the troubleshooting section, insert a piece of paper that is the same thickness as the male
terminal between the terminal and the short spring to release it (Refer to the illustrations on the next 3 pages).
CAUTION:
Never release the activation prevention mechanism on the squib connector even when inspecting
with the squib disconnected.
NOTICE:
Do not release the activation prevention mechanism unless specially directed by the trouble-
shooting procedure.
To prevent the terminal and the short spring from being damaged, always use a piece of paper
that is the same thickness as the male terminal.
