(h) SEAT BELT PRETENSIONER
(1) Never measure the resistance of the seat belt pre-
tensioner. (This may cause the pretensioner oper-
ates, which is very dangerous.)
(2) Oil or water should not be put on the front seat outer
belt and the front seat outer belt should not be
cleaned with detergents of any kind.
(3) Store the front seat outer belt where the ambient
temperature remains below 80
C (176
F), without
high humidity and away from electrical noise.
(4) When using electric welding, first disconnect the
connector (yellow color and 2 pins) installed at the
center pillar lower garnish before starting work.
(5) When disposing of a vehicle or a front seat outer
belt alone, the seat belt pretensioner should be acti-
vated before disposal (See Pub. No. RM599E,
page BO–153). Perform the operation in a safe
place away from electrical noise.
(i) AIRBAG SENSOR ASSEMBLY
(1) Never reuse the airbag sensor assembly involved
in a collision when the SRS has deployed.
(2) The connectors to the airbag sensor assembly
should be connected or disconnected with the sen-
sor mounted on the floor. If the connectors are con-
nected or disconnected while the airbag sensor as-
sembly is not mounted to the floor, it could cause
undesired ignition of the supplemental restraint sys-
tem.
(3) Work must be started after 90 seconds from the
time the ignition switch is turned to the ”LOCK” posi-
tion and the negative (–) terminal cable is discon-
nected from the battery, even if only loosing the set
bolts of the airbag sensor assembly.
(j) WIRE HARNESS AND CONNECTOR
The SRS wire harness is integrated with the instrument
panel wire harness and the cowl wire harness assembly
and floor wire harness assembly. The wires for the SRS
wire harness are encased in a yellow corrugated tube. All
the connectors for the system are also a standard yellow
color. If the SRS wire harness becomes disconnected or
the connector becomes broken due to an accident, etc.,
repair or replace it as shown on Pub. No. RM599E, page
RS–65.

– SUPPLEMENTAL RESTRAINT SYSTEMSRS AIRBAG
(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.
7. DISCONNECTION OF SIDE AND CURTAIN SHIELD
AIRBAG SENSOR CONNECTOR
(a) With 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.
