SYSTEM DESCRIPTION

FUNCTION OF SRS CONNECTORS

(a) Location of activation prevention mechanism

(b) Function of activation prevention mechanism

(1) The activation prevention mechanism is designed to create a short circuit automatically between the positive (+) and negative (-) terminals of an airbag power source connector when disconnected.

(2) The short spring plate contained in the connector creates a closed circuit on the airbag side (no potential difference can occur between both terminals), preventing accidental airbag deployment when servicing.

(c) Releasing of activation prevention mechanism

(1) To release the activation prevention mechanism, insert a piece of paper with the same thickness as the male terminal (approximately 0.5 mm [0.0197 in.]) between the terminals and short spring to break the connection.

(2) Refer to the following illustrations concerning connectors utilizing the activation prevention mechanism and its release method.

CAUTION:

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

HINT:

To prevent improper operation due to static electricity, etc., the connector of the SRS airbag squib circuit has a short mechanism, and the airbag terminal is shorted while the connector is disconnected.
