Airbag Handling and Storage
Do not disassemble an airbag, lt has no serviceable
parts. Once an airbag has been deployed, it cannot be
repaired or reused.
For temporary storage of an airbag during service,
observe the following precautions.
. Store the removed airbag with the pad surface up.
Never put anything on the airbag.
To prevent damage to the airbag, keep it free from
any oil, grease, detergent, or water,
23-15
. Store the removed airbag on a secure, flat surface
away from any high heat source (exceeding 200'Fi
Never perform electrical inspections to the airbags,
such as measuring resistance.
Do not position yourself in front of the airbag during
removal, inspection, or replacement.
Refer to the scrapping procedures for disposal of a
damaged airbag.

Precautions and Procedures {cont'dl
SRS Unit, Front lmpact Sensors, and Side
lmpact Sensors
. Be careful not to bump or impact the SRS unit, front
impact sensors, or side impact sensors whenever the
ignition switch is ON (ll), or for at least 3 minules after
the ignition switch is turned OFF.
. During installation orreplacement, be careful notto
bump (by impact wrench, hammer, etc.) the area
around the SRS unit, front impact sensors, and sjde
impact sensor. The airbags could accidentally deploy
and cause damage or injury.
After a collision in which any airbags or seat belt
tensioners were deployed. replace the SRS unit, front
impact sensors, and other related components (see
page 23-112). After a collision in which a side airbag
was deployed. replace the side impact sensor on the
deployed side and the SRS unit. After a collision in
which the airbags or the side airbags did not deploy,
inspect for any damage or any deformation on the
SRS unit, front impact sensors, and the side impact
sensors. lf there is any damage, replace the SRS unit
and/or the sensors.
23-16
.j
. Do not disassemble the SRS unit, front impact sensors,
or side impact sensors.
. Turn the ignition switch OFF, disconnect the battery
negative cable, and wait at least 3 minules before
beginning installation or replacement of the SBS unit,
or disconnecting the connectors from the SRS unit.
. Be sure the SRS unit, front impact sensors, and side
impact sensors are installed securely. with the
mounting bolts torqued to 9.8 N.m (1.0 kgf.m,7.2 lbf.ft)
. Do not spill wateroroil on the SRS unit, front impact
sensors, or the side impact sensors, and keep them
away from dust.
. Store the SRS unit, front imDact sensors and side
impact sensors in a cool (less than 104"F/40'C) and
dry (less than 80 % relative humidity, no moisture)
area.

Wiring Precautions
Some of the SRS wiring can be identified by a special
yellow outer covering, and the SRS connectors can be
identified by their yellow color.
Observe the instructions described in this section.
. Never attempt to modify. splice, or repair SRS wiring.
lf there is an open or damage in SRS wiring, replace
the harness.
Be sure to install the harness wires so they do not get
Dinched or interfere with other Darts.
Make sure all SRS ground locations are clean, and
grounds are securely fastened for optimum metal-to-
metal contact. Poor grounding can cause intermittent
problems that are difficult to diagnose.
Precautions for Electrical Inspections
. When using electricaltest equipment, insertthe
probe of the tester into the wire side of the connector.
Do not insert the probe of the tester into the terminal
side of the connector, and do not tamper with the
connector.
Use a U-shaped probe. Do not insert the probe
forcibly.
Use specified service connectors in tro u bleshooting.
Using improper tools cou ld cause an error in
inspection due to poor metal-to-metal contact.

Precautions and Procedures (cont'dl
Spring-loaded Lock Connector
Some SRS system connectors have a spring-loaded
lock.
Front Airbag Connectors:
Disconnecting
To release the lock. pullthe spring-loaded sleeve (A)
toward the stop (B) while holding the opposite half of
the connector. Then pullthe connector halves apart, Be
sure to pull on the sleeve and not on lhe connector.
Connecting
1. To reconnect, hold the pawl-side connector, andpress on the back of the sleeve-side connector in
the direction shown. As the two connector halves
are pressed together, the sleeve (A) is pushed back
by the pawl (C). Do not touch the sleeve.
When the connector halves are completelV
connected, the pawl is released, and the spring-
loaded sleeve locks the connector.
23-18
\J
Side Airbag Connector:
Disconnecting
To release the lock, pullthe spring-loaded sleeve (A)
and the slider {B) while holding the opposite half of the
connector. Then pullthe connector halves apart. Be
sure to pull on the sleeve and not on the connector half.
Connecting
Hold both connector halves, and press them firmly
together until the projection (C) of the sleeve side
connector clicks.J

Backprobing Spring-loaded Lock Connectors
When checking voltage or resistance on this type of
connector the first time, you must remove the retainer
to insert the tester orobe from the wire side.
NOTE: lt is not necessary to reinstall the removed
retainer;the terminals will stay locked in the connector
housrno.
A
To remove the retainer (A), insert a flat-tip screwdriver
(B) between the connector body and the retainer, then
carefully pry out the retainer. Take care not to break the
connector.
Seats with Side Airbags
Seats with side airbags have a "SIDE AIRBAG" label on
the seat-back. Because the component pans (seat-back
cover, cushion, etc.) of seats with and without airbags
are different, make sure you install only the correct
replacement parts.
When cleaning, do notsaturatethe seatwith liquid,
and do not sDrav steam on the seal
Do not reoalr a torn or fraved seat-back cover.
ReDlace the seat-back cover.
After a collision in which the side airbag was
deployed, replace the side airbag with new parts. lf
the seat-back cushion is split, it must be replaced. lf
the seat-back frame is deformed, it must be replaced.
Never put aftermarket accessories on the seat {covers,
pads, seat heaters, lights, etc.).

Disconnecting System Connectors
Before removing a front airbag. side airbag, or other SRS related devices {the SRS unit, the cable reel, the front impact
sensors, the side impact sensors, the seat belt buckle tensioners, and the seat belt tensioner connector), disconnectingconnectors from related devices, or removing the dashboard or the steering column, disconnect the airbag connectorsor the side airbag connectors to prevent accidental deploVment.
Turn the ignition switch OFF, disconnect the negative cable from the battery, and wait at least 3 minutes before
beginning the following procedures.'BeforedisconnectingSRSunitconnectorA(1)fromtheSRSunit,disconnectthedriver'sairbag4Pconnector(3).
