- FUNCTION OF SRS CONNECTORS
- Location of activation prevention mechanism
- Function of activation prevention mechanism
- 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.
- 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.
- Releasing of activation prevention mechanism
- 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.
- Refer to the following illustrations concerning connectors utilizing the activation prevention mechanism and its release method.WARNING:
Never release the activation prevention mechanism on the squib connector even when inspecting with the squib disconnected.
NOTE:- Do not release the activation prevention mechanism unless specified by the troubleshooting procedure.
- To prevent the terminals and short spring from being damaged, always use a piece of paper with the same thickness as the male terminal.
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.
