The rear window defogger is controlled by the integrated control unit, Pushing the defogger switch in the instrument
panel it sends a signal to the defogger time. in the integrated control unit, and the detogger stays on tor 25 minutes
or until the ignition switch is turned off. The indicator light in the switch comes on when the deJogger works.

Rear Window Defogger
Function Test
CAUTION: Be carelul not to scratch 01 damago ths
defogger wires with th€ tsster probe.
1 . Check for voltage between the positive terminal and
body ground with the ignition switch and the delog-
ger switch ON. There should be battery voltage.
a lf there is no voltage, check for
- laulty detogger relay.- faulty defogger switch.- faulty integrated control unit.- an open in the BLK/GRN wire
a lJ there is baftery voltage, go to step 2.
NEGATIVE TERMIiIALPOSITIVE TERMINAL
Turn the rear window detogger switch OFF, Check
for continuity between the negative terminal and
body ground.
a It there is no continuity, check to. an open in the
defogger ground wire.
a ll there is continuity, go to step 3.
Touch the voltmeter positive lead to the halfway
point of each defogger wire, and the negative lead
to the negative terminal.
There should be apptoximately 6 V with the ignition
switch and defogger switch ON.
a lf the voltage is as specified, the defogger wire
is OK.
a lf the voltage is not as specified. repai, the defog-
ger wire:
lf it is more than 6 V, look for the damage on
the negative half on the grid.
- lf it is less than 6 V. iook for the damage on
the positive half of the grid.
Defogger Wires Repair
NOTE: To make an eftective repair. the broken section
must be no longer than one inch.
1 . Lightly rub the area around the break with line steel
wool, then clean it with alcohol.
2. Carefullv mask above and below the broken portion
of the defogger wire with cellophane tape.
Using a small brush, apply a heavy coat of silver con-
ductive paint extending about 3 mm ( 1/8 inl on both
sides of the break. Allow 30 minutes to dry.
NOTE: Thoroughly mix the paint before use.
Check for continuity in the repaired wire.
Apply a second coat of paint in the same way.

Steerin g-related Precautions
Steering Wheel and Cable Reel Alignment
NOTE: To avoid misalignment of the steering wheel or
airbag on reassembly, make sure the wheels are turned
straight ahead before removing the steering wheel.
Rotate the cable reel clockwise unit it stops.
Then rotate it co u nterclockwise (approximately two
turnsl until:
- The yellow gear tooth lines up with the alignment
mark on the cover.- The arrow mark on the cable reel label points straight
up.

Steering Column Removal
CAUTION:
. Bofore romoving tho 3l6oring column, first discon'
nect tha connector between ths cablo 16ol snd tho
SRS main harness.
. lf th6 stssring column is going to be removed with-
out dbmounting the stesring wh6el, lock the sl6sr-
ing by turning th€ ignition k.y to o-LOCK po3ition or
removo tha k€y llom ths ignilion so that th6 3loaring
wheel will not turn.
Do not replace the original steering wheei with any
other design, since it will make it impossible to properly
instsll the airbag (only use genuine Honda replacement
oans).
After reassemblv confirm that 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 adjustment of the tie-rods, not by remov-
ing and repositioning the steering wheel.

Supplemental Restraint System (SRSI
Troubleshooting
Self-diagnosis Function
The SRS unit includes a self-diagnosis function. lf there
is a failure in the sensors. SRS unit, inflator, or their cir-
cuits, the SRS indicator light in the gauge sssembly
comes ON.
As a system check, the SRS indicator light also comes
on when the ignition is first turned ON to the (ll) posi-
tion. lf the light goes off after approximately six sec-
onds, the system is OK.
lf the SRS indicator lighr remains on (or fails to come on
in the system check mode), one of the SRS components
(or the wiring/connectors inbetween) is laulty
Troubleshooting Precautions
a Always use the test harness. Do not use test probes
directly on component connector terminals or wires;
you may damage them or the SRS unit.
a When connecting any of the test harnesses to the
system, push the connectors straight-in; do not bend
the connector terminals,
. Before disconnecting any part of the SRS wire har-
ness, connect the shon connector (RED) on the driv-
er's airbag. On cars equipped with a front passen-
ger's airbag, connect short connectors on the driver's
airbag and the front passenger's airbag.
SRS Indicator Light Troubleshooting
Possiblo conditions:
1. SRS indicator light does not come on at all - see
page 23-278.
2. SRS indicator light stays on constantly - see page
23-242.
3. SRS indicator light comes on in combination with a
failure of another electrical system (charging sys-
tem light). Check for damage/corrosion at the
under-dash tuse/relay box connector.
NOTE:
. Before starting the applicable troubleshooting. check
the condition of all SRS connectors and ground
points.
. lf the fault is not found after completing the applica-
ble troubleshooting, substitute a known-good SRS
unit and check whether the indicator light goes off.
