Precautions/ Procedures
)General Precautions
r Carefully inspect any SRS part before you install it Do
not install any part that shows signs of being dropped
or improperly handled' such as dents, cracks or defor-
mation:
- Airbags- Cable reel
- SRS unit
-
Use only a digital multimeter to check the system lf
it's not a Honda multimeter, make sure its output ls
1O 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'
I Do not install used SRS parts from another vehicle
When making SRS repairs, use only new pans'
) Except when performing electrical inspections'
always disconnect both the negative cable and posl-
tive cable from the battery, and wait at least three
minutes before beginning work
r Replacement of the combination light and wiper/
washer switches and cruise control switch can be
done without removing the steering wheel:
- Combinalion light and wiper/washer switch replace
ment, see section 23
- Cruise control sevresume switch replacement' see
section 23.
. 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 airbag(s) could accidental-
ly deploy and cause damage or injury'
. Whenever the airbag{s) has(have) been activated'
replace the SRS unit.l,

Airbag Handling and Storage
Do not try to disassemble the airbag assembly. lt has no
serviceable parts Once an airbag has been operated
(deployed). it cannot be repaired or reused'
For temporary storage of the airbag assembly during ser-
vice. olease observe the following precauttons:
. store the .emoved airbag assemblv with the pad sur-
face uo The driver's (and front passenger's) airbag
connecto''s'-as {have) a built.in short contact (see
page 2a-l 1

force lo c.usa 3a.ix! intury
AIRBAG CONNECTORS(With built in shon contact)
. Store the removed airbag assembly on a secure flat
surface away from any high heat source {exceeding
212"FI1OO"CJ and free of any oil' grease, detergent or
water.
CAUTION: lmproper handling or storage can intern'lJy
damage the airbag assembly, making it inoperativo
lf you suspect the airbag assembly has been dam€cd'
inslall a new unit. and relsr lo the Deployment/DisPG'l
olocedules for disposing ol the damaged airbag

Troubleshooting
t)
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' I
tion in memory. For easier troubleshooting, this data can be retrieved via a data link circuit l
. When you turn the ignition switch ON (ll), the SRS indicator will come on. ll it goes off after six seconds. the system is
norma l.
. lf there is an 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-
tery is disconnected.
o when you connect the scs service connector to the service check connector (2P), and turn the ignition switch oN (ll),

. After reading and recording the DTC. proceed with the troubleshooting for this code'

r when-ever the ignition switch is oN (ll). or has been turned oFF for lessthan three minutes, be careful nottobumpthe
SRS unit; the airbags could accidentally deploy and cause damage or injuries
. Before you ,"n1ou" th" SRS main harness, disconnect the driver's airbag connector (and the front passenger's airbag
connector).
. Make sure the battery is sufficiently charged {see section 23}. lf the battery is dead or low, measuring valLles 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 or the special tools'
For backprobing spring-loaded lock type connectors, refer to page 24-9'
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

Power Distribution Schematics
Power Distribution schematics show how power is supplied from the positive battery terminal to
various circuits in the car. Refer to the Power Distribution section to get a more detailed picture
of how power is supplied to the circuit you're working on.
From Battery to lgnition Switch, Fuses, and Relays
Individual circuit schematics begin with a fuse. The first half of Power Distribution, however,
shows the wiring "upstream" between the battery and the fuses.

terminal number, look up that name or number in the Connector-to-Harness Index that begins
on page 203. The chart lists how many cavities a connector has, where it's located, and what
it connects to. The related illustration shows the connector's location on the harness, and the
harness routing.
