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).
CAUTION: Never release the activation prevention mechanism on the squib connector even when inspecting with the squib disconnected.
