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
FRONT PASSENGER'SAIREAGDRIVER'S AIRBAG
FRONT PASSENGER'SSEAT BELT TENSIONER{'98 - 00 modelsl
)
SRS UNITDRIVER'S SEAT BELTTENSIONER l'98 - 0O modeb)
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).

Precautions/Procedures
)General Precautions
Carefully inspect any SRS part before you install it.
Do not install any part that shows signs of being drop-
ped or improperly handled, such as dents, cracks or
deformation:
- Airbags- Cable reel- SRS unit- Seat belt tensioners
N
)-
Use only a digital multimeter to check the system, lf
it's not a Honda multimeter, make sure its output is
10 mA (0,01 A) or less when switched to the smallest
value in the ohmmeter range. A tester with a higher
output could damage the airbag circuit or cause acci-
dental deployment and possible injury.
Do not install used SRS Dans from another vehicle,
When making SRS repairs, use only new pans.
Except when performing electrical inspections,
always disconnect both the negative cable and posi-
tive cable from the batterv. and wait at least three
minutes before beginning work.
Replacement of the combination light and wiper/
washer switches and cruise control switch can be
done without removing the steering wheel:
- Combination light and wiper/washer switch replace-
ment {see section 231.- Cruise control sevresume switch replacement (see
section 41.
Whenever the ignition switch is ON {ll}, or has been
turned OFF for less than three minutes, be careful not
to bump the SRS unit; the airbags could accidentally
deploy and cause damage or injuries.
Whenever the airbag has been activated, replace the
SRS unit.
The original radio has a coded theft protection circuit.
Be sure to get the customer's code number before dis-
connecting the battery cables.

Airbag/Seat Belt Tensioner
Handling and Storage
Do not try to disassemble an airbag or a seat belt ten-
sioner. They have no serviceable parts. Once an airbag
or a seat belt tensioner have been deployed. they cannot
be repaired or reused.
For temporary storage of an airbag or a seat belt ten-
sioner during service, please observe the following pre-
cautons:
. Store the removed airbag with the pad surface up.
The driver's/front passenger's airbag connectors and
seat belt tensioner connectors have a built-in short
contact (see page 24-211.
@ r th€ airb.g is impropcrty stor€d face down,
accidental deployment could propel the unit with enough
forc€ to caus6 serious iniury,
Store the removed on a secure flat surface awav from
any high heat source (exceeding 212"F/100'C) and
free of any oil, grease. detergent or water.
lmproper handling or storage can internally damage
the airbag and seat belt tensioner. making them inop-
erative.
lf you suspect the airbag and seat belt tensioner have
been damaged, install new units and refer to the
Deploymenvoisposal Procedures for disposing of the
damaoed units.
