(a) All connectors in the SRS are colored in yellow to distin-
guish them from other connectors. Connectors having
special functions and specifically designed for the SRS
are used in the locations shown on the previous page to
ensure high reliability. These connectors use durable
gold±plated terminals.
(1) Terminal twin±lock mechanism
Each connector has a two±piece component con-
sisting of a housing and a spacer. This design en-
ables the terminal to be locked securely by two lock-
ing devices (the retainer and the lance) to prevent
terminals from coming out.
(2) Airbag activation prevention mechanism
Each connector contains a short spring plate. When
the connector is disconnected, the short spring
plate automatically connects positive (+) terminal
and negative (±) terminal of the squib.

The type of connector is shown in the diagram on the previous
page.
(3) Electrical connection check mechanism
This mechanism electrically checks that connectors
are connected correctly and completely. The electri-
cal connection check mechanism is designed so
that the disconnection detection pin connects with
the diagnosis terminals when the connector hous-
ing lock is locked.
HINT:
The connectors shown in this illustration are connectors, º1º, º2º
and º3º in step 10 and 11.

(4) Connector twin±lock mechanism
With this mechanism connectors (male and female
connectors) are locked by 2 locking devices to in-
crease the connection reliability. If the primary lock
is incomplete, ribs interfere and prevent the sec-
ondary lock.
(b) When the vehicle is involved in a frontal collision in the
hatched area (Fig. 1) and the shock is larger than the pre-
determined level, the SRS is activated automatically. A
safing sensor is designed to go on at a smaller decelera-
tion rate than the airbag sensor. As illustrated in Fig. 2,
ignition is caused when current flows to the squib, which
happens when a safing sensor and the deceleration sen-
sor go on simultaneously. When a deceleration force acts
on the sensors, 2 squibs in the driver airbag and front pas-
senger airbag ignite and generate gas. The gas discharg-
ing into the driver airbag and front passenger airbag rap-
idly increases the pressure inside the bags, breaking
open the steering wheel pad and instrument panel door.
Bag inflation then ends, and the bags deflate as the gas
is discharged through discharge holes at the bag's rear or
side.

12. DISCONNECTION OF FRONT AIRBAG SENSOR AND
SIDE AIRBAG SENSOR CONNECTOR
(a) While holding both flank sides of the outer, slide the outer
to the direction shown by an arrow.
(b) Lock of the connectors is released, then disconnect the
connectors.
HINT:
Make sure to hold both flank sides of the outer. If holding the top
and bottom sides, it will obstruct disconnection.
13. CONNECTION OF FRONT AIRBAG SENSOR AND
SIDE AIRBAG SENSOR CONNECTOR
(a) Align the male connector (of the side of sensor) and fe-
male connector in the same direction as shown in the il-
lustration and fit in them without rubbing.
(b) As they are fitted in, the outer slides rearward. Press it un-
til the outer returns to its original position again.
If fitting stops half way, connectors will separate.
(c) Make sure to insert until they are locked. After fitting in,
pull them slightly to check that they are locked. (When
locked, make sure that the outer returns to its original
position and sound at the time of fitting in can be heard.)
HINT:
Do not fit in while holding the outer.
When fitting in, the outer slides. Do not touch it.

15. CONNECTION OF SIDE AIRBAG CONNECTOR
(a) Align a lock part of male connector and a slider of female
connector in the same direction as shown in the illustra-
tion, fit in them without rubbing.
(b) Make sure to insert until they are locked. After fitting in pull
them slightly to check that they are locked. (When locked,
make sure that the outer returns to its original position and
sound at the time of fitting in can be heard.)
HINT:
As the slider slides, do not touch it.
Be careful not to deform the release board. If the release
board is deformed, replace it with a new one.
