(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.
