SRS air bag special connector

To enhance the system reliability, a connector lock 
switch is integrated in the SRS-ECU connector, the 
air bag module connectors and the clock spring con-
nector (black connector "A" shown in the illustration

SQUIB CIRCUIT CONNECTOR LOCK SWITCH
The switch is a mechanism that shorts the power 
supply terminal to the ground terminal automatically 
in the air bag squib circuit when the connector is dis-
connected. A "short" spring is integrated inside the 
connector. This spring prevents static electricity from 
flowing to the squib by shorting the power supply ter-
minal to the ground terminal (i.e. there is no potential 
difference between the two terminals).

CAUTION

When the connector is disconnected, there will 
be short circuit between the terminals. This is not 
a fault.

WARNING LIGHT CIRCUIT CONNECTOR LOCK SWITCH
The switch is a mechanism that shorts the power supply termi-
nal to the ground terminal automatically in the warning light cir-
cuit when the connector is disconnected. Its structure is similar 
to the squib circuit connector shorting mechanism.
