(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.

REMOVAL
NOTICE:
If the wiring connector of the SRS is disconnected
and the ignition switch is at ON or ACC position, DTCs
will be recorded.
Never use the airbag parts from another vehicle.
When replacing parts, replace with new parts.
1. DISCONNECT AIRBAG CONNECTOR
(a) Remove the glove compartment door finish plate inside
the instrument panel box.
NOTICE:
When handling the airbag connector, take care not to dam-
age the airbag wire harness.
(b) Pull up the connector.
(c) Disconnect the front passenger airbag connector.
2. REMOVE THESE PARTS: (See page BO-50)
(a) Instrument panel box
(b) Heater to register duct No.4
3. REMOVE FRONT PASSENGER AIRBAG ASSEMBLY
(a) Remove the 4 bolts.
(b) Pull the front passenger airbag assembly to remove it.
CAUTION:
Do not store the front passenger airbag assembly
with the airbag deployment direction facing down-
ward.

INSPECTION
1. VEHICLES NOT INVOLVED IN A COLLISION
(a) Do a diagnostic system check.
(See page DI-557)
(b) Do a visual check which includes the following items with
the front passenger airbag assembly installed in the ve-
hicle.
Check cuts, minute cracks or marked discoloration on the
front passenger airbag assembly and instrument panel.
2. VEHICLE INVOLVED IN A COLLISION AND AIRBAG IS
NOT DEPLOYED
(a) Do a diagnostic system check.
(See page DI-557)
(b) Do a visual check which includes the following items with
the front passenger airbag assembly removed from the
vehicle.
Check cuts minute cracks or marked discoloration
on the front passenger airbag assembly.
Check cuts and cracks in wire harness, and for chip-
ping in connectors.
Check the deformation or cracks on the instrument
panel and instrument panel reinforcement.
HINT:
If the instrument panel or instrument panel reinforcement
is deformed or cracked, never repair it. Always replace it
with a new one.
There should be no interference between the instrument
panel and the front passenger airbag assembly.
CAUTION:
For removal and installation of the front passenger airbag
assembly, see page RS-21, RS-31 and be sure to follow the
correct procedure.

3. VEHICLE INVOLVED IN A COLLISION AND AIRBAG IS
DEPLOYED
(a) Do a diagnostic system check.
(See page DI-557)
(b) Do a visual check which includes the following items with
the front passenger airbag assembly removed from the
vehicle.
Check the deformation or cracks on the instrument
panel and instrument panel reinforcement.
Check the damage on the connector and wire har-
ness.
HINT:
If the instrument panel or instrument panel reinforcement is de-
formed or cracked, never repair it. Always replace it with a new
one.

1. AIRBAG DEPLOYMENT WHEN SCRAPPING VE-
HICLE
HINT:
Have a battery ready as the power source to deploy the airbag.
(a) Confirm functioning of the SST.
CAUTION:
When deploying the airbag, always use the specified SST:
SRS Airbag Deployment Tool.
SST 09082-00700
(1) Connect the SST to battery.
Connect the red clip of the SST to the battery posi-
tive (+) terminal and the black clip to the battery neg-
ative (-) terminal.
HINT:
Do not connect the yellow connector which will be connected
with the supplemental restraint system.
(2) Confirm functioning of the SST.
Press the SST activation switch, and confirm the
LED of the SST activation switch lights up.
CAUTION:
If the LED lights up when the activation switch is not being
pressed, SST malfunction is probable, so definitely do not
use the SST.
(b) Disconnect the airbag connector.
(1) Remove the glove compartment finish plate inside
the instrument panel box.
NOTICE:
When handling the airbag connector, take care not to dam-
age the airbag wire harness.
(2) Pull up the connector.
(3) Disconnect the airbag connector.
