Inspect the connector and socket terminals to be
sure they are all making good contact.
lf the terminals are bent, loose or corroded. repair
them as necessary, and recheck the system.
lf the terminals look OK, make the following
input tests at the connector,- lf any test indicates a problem, find and correct
the cause, then recheck the system.- lf all the input tests prove OK, the control unit
must be faulty; replace it.

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.

Replacement
!@@ store a .emove airbag assambly with thepad surtace up. lf the airbag is improperly stored face
down, accidental deploymont could propel the unit withenough force to cause sorious iniury.
CAUTION:
. Alwsys disconnect the airbag connoctor(s) when ih€harness is disconngcted.
. Do not disassemble or tamper with the airbag.
NOTE: Carefully inspect the airbag assembly beforeinstalling it. Do not install an airbag that shows signs ofbeing dropped or improperly handled. such as dents,cracks or deformation.
l.Disconnect the battery negative cable. then discon-nect the positive cable from the battery, and wait atleast three minutes.
Remove the access panel from the steering wheel,then disconnect the 2P connector between the driv-er's airbag and cable reel.
NOTE: When disconnected, the airbag connector isautomatically shorted.

How To Use This Manual
Circuit Schematics
oa
Each schematic represents one circult. A
circuit's wires and components are arranged
to show current flow, from power at the top of
the page, to ground, at the bottom.
Shared Circuits
Other circuits may share power or ground
terminals or wiring with the circuit shown. A
wire that connects one circuit to another, for
example, is cut short and has an arrowhead
at the end of it pointing in the direction of
current flow. Nelit to the anowhead is the
name o{ the circuil or comoonent which
shares that wiring. To quickly check shared
wiring, check the operation of a component it
serves. lf that component works, you know
the shared wiring is OK.
Connectors
All in-line and fuse box connectors are
numbered (C725, C416, etc.).
Component connectors are not numbered
but are identiJied by the name of the
component. lf a componenl has more than
one connector, each connector is assigned
a letter (A, B, C, etc.). Below most connector
numbers and comDonent names are
PHOTO and VIEW numbers. The PHOTO
number refers to a Dhoto in the back of the
book that shows lhe conneclor's location on
the car. The VIEW number refers to an
illustration in the back of the book that
shows the connector face, wire colors,
connector cavity numbers, and other details.
The connector cavity numbering sequence
begins at the top left corner oJ the connector
as seen from either of the viewooints shown
on page ffl . Disregard any numbers
molded into the connector housino.
Wires
Wires are identilied by the abbreviated
names of their colors; the second color rs the
color of the stripe. Wires are also identified by
their location in a connector. The number '2"
next to the male and female wire terminals at
C416, for example, means those terminals
join in cavity 2 of connector C416.
Symbols
