1. Before installing the retactor, check that the seat belt
can be pulled out freely
2. Make sure that the seat belt does not lock when the
retractor is leaned slowly up to 15'from the mounted
Dosition. The seat belt should lock when the retractor
is leaned over 40".

After installing the anchors, check for free move-
ment on the anchor bolts lf necessary, remove the
anchor bolts, and check that the washers and other
parts are not damaged or improperly installed.
Check the seat belts for damage or discoloration.
Clean with a shop towel if necessary.
CAUTION: Uso only soap and wator to clean.
NOTE: Dirt build-up in the metal loops of the upper
anchors can cause the seat belts to retract slowly
Wipe the inside of the loops with a clean cloth damP
ened in isopropyl alcohol.
Check that the seat belt does not lock when pulled
out slowlv. The seat belt is designed to lock only
during a sudden stop or impact.
Make sure that the seat belt will retract automatically
when released.
For each passenger's seat belt, make sure that the
locking mechanism in the seat belt retractor will
engage when the seat belt is pulled all the way out.
Replace the seat belt with a new assembly if there is
any abnormality. Do not disassemble any part of
the seat belt for any reason.

Description
J)
The SRS is a safety device which, when used in conjunction with the seat belt, is designed to help protect the driver and
front passenger in a frontal impact exceeding a certain set limit. The system consists of the SRS unit (including safing sen-
sor and impact sensor), the cable reel, the driver's airbag and front passenger's airbag.
Seat Bolt Tensioner {'98 - 00 models}
The seat belt tensioner is linked with the SRS airbags to further increase the effectiveness of the seat belt. In a front-end
collision, the tensioner instantly retracts the belt firmly to secure the occupants in their seats

Operation
The main circuit in the SRS unit senses and judges the force of impact and, if necessary, ignites the intlator charges. lf bat
tery voltage is too low or power is disconnected due to the impact, the voltage regulator and the back-up power circuit
respectively will keep voltage at a constant level.
For the SRS to operate:
(1) The impact sensor must activate, and send electric signals to the microprocessor.
(2) The microprocessor must compute the signals, and send them to the airbag inflators (and seat belt tensioners).
(3) The inflators must ignite and deploy the airbags (and activate the tensioners).
Selt-diagnosis System
A self-diagnosis circuit is built into the SRS uniU when the ignition switch is turned ON (ll), the SRS indicator Iight comes
on and goes off after about six seconds if the system is operating normally.
lf the light does not come on, does not go off after six seconds, or it comes on while driving, it indicates an abnormality in
the system. The system must be inspected and repaired as soon as possible.
For battery serviceability, the memory will store the cause of the malfunction, and the data link circuit passes on the infor
mation from the memory to the data link connector (DLC). This information can be read with the Honda PGM Tester con-
nected to the DLC {16P).

Replacement
After a collision in which the airbags were deployed, the
airbags, the seat belt tensioners (if so equipped), and
the SRS unit must be replaced.
@ Store a removed airbag with the pad su.-
tacs up, lf th€ airbag is improperly stored face down.
accidental deployment could propal the unit with
enough forc€ io causg serioug iniury.
CAUTION:
. Always disconnoct the drivor's airbag connector
when the SRS main harness is disconnactod.
. Do not disassemble or tamper with ihe airbag.
NOTE:
Do not install used SRS parts from another vehicle,
When repairing, use only new SRS parts.
Carefully inspect the airbag before you install it. Do
not install an airbag that shows signs of being
dropped or improperly handled, such as dents, cracks
or deformation.
Disconnect the battery negative cable, then discon-
nect the positive cable from the battery, and wait at
least three minutes.
Remove the access panel from the steering wheel.
then disconnect the 2P connector between the driv-
er'6 airbag and cable reel. When disconnected. the
airbag connector is automatically shorted.
