Turn SignallHazard Flasher System
Turn Signal/Hazard Relay Input Test
SRS components are located in this area. Review theSRS component /ocations, precautions, ano proceoures
in the SRS section (24) before performing repairs or ser-vice.
1.Remove the turn signal/hazard relay from the under-dash fuse/relay box.
Inspect the relay and luselrelay box socket terminals
to be sure they are all making good contact.
lf the terminals are bent, loose or corroded,reparr them as necessary, and recheck the system.lf the terminals look OK, make the following
input tests at the fuse/relay box socket.- lf any test indicates a problem, find and cor-
rect the cause, then recheck the system.- lf all the input tests prove OK, the turn signal/
hazard relay must be faulty; replace it.

Rear Window Defogger
Function Test
1. Check for voltage between the positive terminal andbody ground with the ignition switch and defoggerswitch ON.
There should be battery voltage.
. lf there is no voltage. check for:- faulty defogger relay.- faulty defogger switch.- an open ,n the BLK/BLU, WHT/GRN, BLU/YEL,
or BLK wire.
. lf there is battery voltage, go to step 2.
POSITIVE TERMINAL
Check for continuity between the negative terminaland body ground.
lf there is no continuity, check for an open in thedefogger ground wire.
Touch the voltmeter positive probe to the halfwaypoint of each defogger wire, and the negative probe
to the negative terminal. Be careful not to scratch ordamage the defogger wires with the tester probe.There should be approximately 6 V with the ignitionswitch and the defogger switch ON.
. lf the voltage is as specified, the defogger wire isoK.
. lf the voltage is not as specified, repair the defog-ger wire.- lf it is more than 6 V, there is a break in thenegative half of the wire.- lf it is less than 6 V, there is a break in thepositive half of the wire.
23-112
Defogger Wire Repair
NOTE: To make an effective repair, the broken sectionmust be no longer than one inch.
1. Lightly rub the area around the broken section withfine steel wool, then clean it with alcohol.
2. Carefully mask above and below the broken portionof the defogger wire with cellophane tape.
CELLOPHANETAPE
Mix the conductive paint thoroughly. Using a smallbrush, apply a heavy coat of the conductive paint
extending about 1/8" on both sides of the break.Allow 30 minutes to dry.
Check for continuity in the repaired wire.
Apply a second coat of paint in the same way. Let itdry three hours before removing the tape.

)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.
'97 model:
SRS MAIN HARNESS2P CONNECTORCABLE REEL2P CONNECTOR
'98 - 00 models:
UNDER-DASHFUSE/RELAY BOX
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 .
