Switch Test
lMake sure you have the anti-theft code for the
radio, then write down the frequencies for the
radio's preset buttons ('99 - 00 models).
Disconnect the battery negative cable, then disconnect
the positive cable, and wait at least three minutes.
Disconnect the driver's airbag connector (see sec-
tion 24).
Remove the driver's dashboard lower cover (see
section 20).
Disconnect the cable reel sub-harness 3P connector
from the main wire harness.

positive terminal.
lf there is no continuity, replace the cable reel
(see section 24).
lf there is continuity, repair or replace the horn
swtlcn,
lf all tests prove OK, reinstall the driver's airbag
assembly (see section 24), and reconnect the cable
reel sub-harness connector.
Reconnect the driver's airbag connector, and rein-
stall the access panel on the steering wheel.
Reconnect the battery positive cable, then the negative

After installing the airbag assembly, confirm proper
system operation:

Turn the ignition switch ON (ll); the SRS indica-
tor light should come on for about six seconds
and then go off.
Make sure both horn buttons work.

Function Test
CAUTION: Bs careful nol to scralch or damage the defog-
ger wires with the tester probe,
'1. Check for voltage between the positive terminal and
body ground with the ignition switch and defogger
switch ON.
There should be banery voltage.
. lf there is no voltage, check for:- faulty defogger relay.- faulty defogger switch.

2. Check for continuity between the negative terminal
and body ground.
lf there is no continuity, check for an open in the
defogger ground wire.
Touch the voltmeter positive probe to the halfway
point of each defogger wire, and the negative probe
to the negative terminal.
There should be approximately 6 V with the ignition
switch and the defogger switch ON.
. lf the voltage is as specified. the defogger wire is
oK.

ger wrre.- lf it is more than 6 V, there is
negative half of the wire.- lf it is less than 6 V, there is
positive half of the wire.

Defogger Wire Repair
NOTE: To make an effective repair, the broken section
must be no longer than one inch.
1, Lightly rub the area around the broken section with
fine steel wool, then clean it with alcohol.
2. Carefully mask above and below the broken portion
of the defogger wire with cellophane tape.
CELLOPHANETAPE
Using a small brush, apply a heavy coat of silver
conductive paint extending about 1/8" 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. Let it
dry three hours before removing the tape.

Switch Input Test
CAUTION: Be careful not to damagc the rear window
defogger switch or the center panel when prying the
switch out.
NOTE: Before testing, check for blown No. 16 (7.5 A)
fuse in the under-dash fuse/relay box,
1. Pry the switch out of the center panel (see section 20).
2. Disconnect the 5P connector from the switch.
3. Turn the jgnition switch ON (ll), and check the voltage
between the BLVBLU {+) and the BLK (-)terminals.
There should be battery voltage
. lf there is no voltage, check for an open in the
BLVBLU wire.
. lfthere is baftery voltage, go to step 4.
Wire side of famale terminals
connect a jumper wire between the BLK/BLU and
the BLU/YEL terminals.
Turn the ignition switch ON (ll), and check that the
rear window defogger works; if it does. replace the
defogger switch.
