(a)

All connectors in the SRS, except the seat position airbag
sensor connector and occupant classification ECU con-
nectors, are colored yellow to distinguish them from other
connectors. These connectors have special functions,
and are specially designed for the SRS. All SRS connec-
tors use durable gold–plated terminals, and are placed in
the locations shown on the previous page to ensure high
reliability.

(1)

Terminal Twin–Lock Mechanism
Each connector has a two–piece component con-
sisting of a housing and a spacer. This design al-
lows the terminal to be locked securely by two lock-
ing devices (the retainer and the lance) to prevent
terminals from coming out.

(2)

Activation Prevention Mechanism
Each connector contains a short spring plate. When
the connector is disconnected, the short spring
plate automatically connects the positive (+) termi-
nal and negative (–) terminal of the squib.

(3)

Half connection prevention mechanism:
If the connector is not completely connected, the
connector is disconnected due to the spring opera-
tion to the extent that no continuity exists.

(4)

Connector lock mechanism (1):
Locking the connector lock button securely con-
nects the connector.
