SRS AIR BAG SPECIAL CONNECTOR
SQUIB CIRCUIT CONNECTOR SHORTING SWITCH
CONNECTOR ENGAGEMENT CHECK MECHANISM
- The diagnosis spring is assembled on the SRS-ECU wiring harness-side connector. When the ECU-side connector is connected to the SRS-ECU wiring harness-side connector, the diagnosis spring shorts the circuit between the ECU-side connector terminals. The connector engagement is detected electrically by flowing the monitor current to this circuit.
- This mechanism automatically short-circuits the power supply side terminal and earth side terminal of the air bag when the connector is disconnected. A short spring is incorporated in the connector to short-circuit the power supply side terminal and earth side terminal of the air bag (no potential difference between the two terminals) and prevent flow of current by static electricity to the squib.
