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).

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.

Precautions/Procedures
SRS Unit Precautions
Take extra care when painting or doing body work in
the area below the dashboard. Avoid direct exposure
of the SRS unit or wiring to heat guns, welding, or
spraying equipment.
Disconnect the driver's/front passenger's airbag con-
nectors and seat belt tensioner connectors before
working below the dashboard near the SRS unit.
After any degree of frontal body damage, or after a
collision without airbag deployment, inspect the SRS
unit for physical damage. lf it is dented, cracked, or
detormed, reolace it,
Be sure the SRS unit is installed securelv.
Do not disassemble the SRS unit.
Store the SRS unit in a cool {less than about
104"F/40"C) and dry {less than 80o/o humidity. no
moisture) place. Do not spill water or oil on the SRS
unit, and keep it awav from dust.
During installation or replacement, be careful not to
bump (impact wrench, hammer, etc.) the area a[ound
the SRS unit, The airbags could accidentally deploy
and cause damage or injury.

Inspection After Deployment
After a collision in which the airbags were deployed.
replace the SRS unit, and inspect the following:
1. Inspect all the SRS wire harnesses. Replace, don't
repair, any damaged harnesses
2. Inspect the cable reel for heat damage, lf there is any
damage. replace the cable reel.
3. After the vehicle is completely repaired, turn the
ignition switch on. lf the SRS indicator light comes
on for about six seconds and then goes off, the SRS
system is OK. lf the indicator light does not function
properly, go to SRS Troubleshooting.

)Steering-related Precautions
Stooring Wh€el and Csble Re6l Alignm€nt
To avoid misalignment of the steering wheel on
reassembly, make sure the wheels are turned straight
ahead beJore removing the steering wheel.
To center the cable reel, rotate the cable reel clockwise
until it stops, Then rotate it counterclockwise (approxi-
mately two and a half turns) until the arrow mark on the
cable reel label points straight up.
Steering Column Bemoval
CAUTION: Before removing the stosring column, tirsi
disconneqt tha connsctor between tho cabls roel and
the SRS main harness.
lf the steering column is going to be removed without
dismounting the steering wheel, lock the sieering by
turning the ignition key to o-LOCK position, or remove
the key trom the ignition so that the steering wheel will
not turn.
LABEL
NOTE:
. When the airbag and cable r6el are disconnected, and
the battery is reconnected and the ignition switch is
turned ON (ll), the SRS unit will store this as an open
in the driver's airbag inflator, and the SRS indicator
light will come on, In such a case, make sure to con-
firm the DTC, then clear the SRS unit memory.
. For disconnecting the spring-loaded lock type con-
nector, refer to page 24-22.

Do not replace the original steering wheel with any other
design because it will make it impossible to properly
install the airbag (use only genuine Honda replacement
partsl.
After reassemblv, confirm the wheels are still turned
straight ahead and that the steering wheel spoke angle
is correct. lf minor spoke angle adjustment is necessary,
do so only by adjusting the tie-rods, not by removing
and repositioning the steering whee .

Troubleshooting
Self-diagnostic Procedures
The self-diagnostic function of the SRS system allows it to locate the causes of system problems and to store this informa-
tion in memory, For easier troubleshooting, this data can be retrieved via a data link circuit.
. When you turn the ignition switch ON (ll). the SRS indicator will come on. lf it goes off after six seconds, the system is
normal.
. lf there is 8n abnormality, the system locates and defines the problem. stores this information in memory, and turns
the SRS indicator light on. The data will remain in the memory even when the ignition switch is turned off or if the bat-
terv is disconnected.
. When you connect the SCS service connector to the service check connector (2P), and turn the ignition switch ON (ll),
the SRS indicator light will indicate the diagnostic trouble code (DTC) by the number of blinks.
. After reading and recording the DTC, proceed with the troubleshooting forthis code.
Precsutions
. 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 accidental airbag deployment and possible injury.
. Whenever the ignition switch isON (ll). or has been turned OFF for less than three minutes, be careful nottobumpthe
SRS unit; the airbags could accidentally deploy and cause damage or injuries.
. Before you remove the SRS main harness, disconnect the airbag and tensioner connectors (see page 24-23).
. Make sure the battery is sufficiently charged (see section 23). lf the battery is dead or low, measuring values won't be
correct.
. Do not touch a tester probe to the terminals in the SRS unit or harness connectors, and do not connect the terminals
with a jumper wire. Use only the backprobe set and the SCS service connector.
For backprobing spring-loaded lock type con nectors, .efet to page 24-22.
Reading the DTC
When the SRS indicator light is on, read the DTC using one of these methods;
A. Connect the Honda PGM Tester to the 16P Data Link Connector {DLC), and follow the tester's prompts. lf the tester
indicates no DTC, DTC 9-1 and DTC 9-2, double-check by jumping the service check connector (2P) and watching the
SRS indicator light (see next page).
