HINT:
The type of connector is shown in the diagram on the previous
page.
(3) Electrical connection check mechanism:
This mechanism electrically checks that the con-
nectors are connected correctly and completely.
The electrical connection check mechanism is de-
signed so that the disconnection detection pin con-
nects with the diagnosis terminals when the con-
nector housing lock is locked.
HINT:
The connectors shown in this illustration are connectors, º1º,
º2º, º3º and º4º in the step 1.
(4) 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.

(5) Connector lock mechanism:
Locking the connector lock button connects the
connector securely.
(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. The
safing sensor is designed to go on at a smaller decelera-
tion rate than the airbag sensor. As illustrated in the Fig.
2, ignition is caused when current flows to the squib,
which happens when the safing sensor and the decelera-
tion sensor go on simultaneously. When a deceleration
force acts on the sensors, 3 squibs in the driver airbag,
front passenger airbag and knee airbag ignite and gener-
ate gas. The gas discharging into the driver airbag, front
passenger airbag and knee airbag rapidly increases the
pressure inside the bags, breaking the horn button assy
and instrument panel. The inflation of the bag then ends,
and the bags deflate as the gas is discharged through dis-
charge holes at the bag's rear or side.

6. DISCONNECTION OF CONNECTOR FRONT SEAT AIRBAG ASSY
(a) Place a finger on the slider.
(b) Slide the slider to release lock.
(c) Disconnect the connector.
7. CONNECTION OF CONNECTOR FOR FRONT SEAT AIRBAG ASSY
(a) Align the lock part of the male connector and the slider of the female connector in the same direction
as shown in the illustration, connect them without rubbing together.
(b) Be sure to insert the connectors until they are locked. After connecting them, pull them slightly to check
that they are locked. (When locking, make sure that the slider returns to its original position and a click
sound can be heard.)
HINT:
When connecting them, the slider slides. Be sure not to touch the slider while connecting, as it may result
in an insecure fit.

8. DISCONNECTION OF AIRBAG FRONT SENSOR, SIDE
AIRBAG SENSOR AND AIRBAG SENSOR REAR CON-
NECTOR
(a) While holding both outer flank sides of the outer, slide the
outer to the direction shown by the arrow.
(b) When the connector lock is released, the connectors are
disconnected.
HINT:
Be sure to hold both outer flank sides. If the top and bottom
sides are held, it will obstruct disconnection.
9. CONNECTION OF CONNECTORS FOR AIRBAG FRONT SENSOR, SIDE AIRBAG SENSOR AND
AIRBAG SENSOR REAR
(a) Align the male connector (on the side of sensor) and female connector in the same direction as shown
in the illustration and connect them without rubbing together.
(b) Be sure to insert the connectors until they are locked. After connecting them, pull them slightly to check
that they are locked. (When locking, make sure that the outer returns to its original position and a click
sound can be heard.)
HINT:
When connecting them, the outer slides. Be sure not to hold the outer while connecting, as it may result in
an insecure fit.
