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

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

Precautions/Procedu res
Steering-related Precautions
Stesring Wheel and Cable Reol Alignment
NOTE: To avoid misalignment of the steering wheel on
reassembly, make sure the wheels are turned straight
ahead before removing the steering wheel.
Rotate the cable reel clockwise until it stops.
Then rotate it counterclockwise {approximately two and
a half turns) until the arrow mark on the cable reel label
points straight up.

St€€rin9 Column Removal
CAUTION:
. Eefore removing thg stggring column. disconnect the
connsstor bqtween the cable r€el and th€ SRS msin
harness.
. lf the stoering column is going to be romoved with-
out dismounting th6 stoering wheel, lock the steer-
ing by turning the ignition key to o-LOCK position, or
remove the key trom the ignition switch so that the
steering wheel will not turn.
NOTE:
When the airbag and cable reel are disconnected,
don't reconnect the battery cable. lf 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.
For disconnecting the spring-loaded lock type con-
nector, refer to page 24-'10.
SRS MAIN HARNESS2P CONNECTOR
Do not replace the original steering wheel with any other
design because it will make it impossible to properly
install the airbag (only use genuine Honda replacement
parts).
After reassembly, 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 wheel.

Airbag
)Replacement
After a collision in which the airbags were deployed' the
airbag assemblies and the SRS unit must be replaced'
!!!@ Store a removed airbag with the pad sur'

enough force to cause serious iniury'
CAUTION:
. Always disconnsct lhe airbag conn€ctor(s) when the

NOTE:
. Do not install used SRS parts from another vehicle'
When repairing, use only new SRS parts'

Procedure.
. lf the red light on the tool comes on, the airbag is
ready to be deployed.
Push the tool's deployment switch. The airbag

and visible; a loud noise and rapid inflation of the
bag, followed by slow deflation).
. lf the airbags deploy and the green light on the
tool comes on. continue with this procedure.

AIRAAG
Doploying th6 Airbag: Out-of-vehicle
NOTE: lf an intact airbag has been removed from a
scrapped vehicle. or has been found defective or dam-
aged during transit, storage or service, it should be
deployed as follows:
@ Po3ition the airbag laca up, outdoors on
flat ground at lsast thirty f€€t (t0 ml from any obstacles
or people.
1. Confirm that the special tool is tunctioning properly
by following the check procedure on this page or on
the tool label.
2. Follow steps 5, 6, 7, and I of the in-vehicle deploy-
menl Drocequre.
Damaged Airbag Spacial Procedure
!@ r an airb.g cannot be deployed, it should
iiiTi-treatcd as normal scrap; il should still be consid-
srsd a potontially oxplosive device that can cau3o ssti-
ous iniury.
1. lf installed in a vehicle, lollow the removal proce-
dure on page 24-67.
2. In all cases. make a short circuit by twisting together
the two airbag inflator wires.
3. Package the airbag in exactly the same packaging
that the new replacement part came in.
4. Mark the outside of the box "DAMAGED AIRBAG
NOT DEPLOYED" so it does not get confused with
your Parts stock.
5. Contact your Honda District Service Manager for
how and where to return it for disposal.
Deployment Tool: Check Procedur€
1. Connect the yellow clips to both switch protector
handles on the tool; connect the tool to a battery.
2. Push the operation switch: green means the tool is
OK: red means the tool is faulty
3. Disconnect the battery and the yellow clips.
