INSPECTION
1. GLASS PRINTED ANTENNA INSPECTION PROCE-
DURE
NOTICE:

When cleaning the glass, use soft dry cloth, and wipe
the glass in the direction of the wire.
Take care not to damage the wires.

Do not use detergents or glass cleaners with abrasive
ingredients.
NOTICE:
In order not to damage the glass printed antenna, wrap up
the tip of the tester stick with aluminum foil as shown in the
illustration and check by holding the aluminum foil with a
finger.
By placing and moving the tester stick along the glass printed
antenna, check if continuity exists.
HINT:
Matching module is built in the bus bar of the glass printed an-
tenna (main terminal side) of CAMRY and no continuity exists
between the terminal and the antenna. Therefore, for the conti-
nuity checking of the glass printed antenna on the main anten-
na side of CAMRY, place one probe of the tester on the position
beside the bus bar (position shown in the illustration) and check
by making the other probe of the tester move along.
2. GLASS PRINTED ANTENNA REPAIR PROCEDURE
(a) Clean the broken wire tips with grease, wax and silicone
remover.
(b) Place the masking tape along both sides of the wire for
repair.
(c) Thoroughly mix the repair agent (Dupont paste No.
4817).

PRECAUTION
1. FOR VEHICLES EQUIPPED WITH SRS AIRBAG AND
SEAT BELT PRETENSIONER
(a) The 1999 CAMRY is equipped with an SRS (Supplemen-
tal Restraint System), such as the driver airbag, front pas-
senger airbag assembly, side airbag assembly and seat
belt pretensioner.
Failure to carry out service operations in the correct se-
quence could cause the supplemental restraint system to
unexpectedly deploy during servicing, possibly leading to
a serious accident.
Further, if a mistake is made in servicing the supplemental
restraint system, it is possible the SRS may fail to operate
when required. Before servicing (including removal or
installation of parts, inspection or replacement), be sure
to read the following items carefully, then follow the cor-
rect procedure described in this manual.
(b) GENERAL NOTICE
(1) Malfunction symptoms of the supplemental re-
straint system are difficult to confirm, so the diag-
nostic trouble codes become the most important
source of information when troubleshooting. When
troubleshooting the supplemental restraint system,
always inspect the diagnostic trouble codes before
disconnecting the battery (See page DI±626).
(2) Work must be started after 90 seconds from the
time the ignition switch is turned to the ºLOCKº posi-
tion and the negative (±) terminal cable is discon-
nected from the battery.
(The supplemental restraint system is equipped
with a back±up power source so that if work is
started within 90 seconds of disconnecting the neg-
ative (±) terminal cable from the battery, the SRS
may deploy.)
When the negative (±) terminal cable is discon-
nected from the battery, memory of the clock and
audio systems will be cancelled. So before starting
work, make a record of the contents memorized by
the each memory system. Then when work is fin-
ished, reset the clock and audio systems as before.
To avoid erasing the memory of each memory sys-
tem, never use a back±up power supply from anoth-
er battery.

SRS AIRBAG
PRECAUTION
NOTICE:

The CAMRY is equipped with SRS, which comprises a driver airbag, front passenger airbag,
and side airbag. Failure to carry out service operations in the correct sequence could cause
the SRS to unexpectedly deploy during servicing, possibly leading to a serious accident. Fur-
ther, if a mistake is made in servicing the SRS, it is possible that the SRS may fail to operate
when required. Before performing servicing (including removal or installation of parts, inspec-
tion or replacement), be sure to read the following items carefully, then follow the correct proce-
dures described in the repair manual.

Malfunction symptoms of the SRS are difficult to confirm, so the DTCs become the most impor-
tant source of information when troubleshooting. When troubleshooting the SRS, always in-
spect the DTCs before disconnecting the battery.

Even in cases of a minor collision where the SRS does not deploy, the steering wheel pad, front
passenger airbag assembly, side airbag assembly (TMC made and TMMK made), airbag sensor
assembly, front airbag sensor and side airbag sensor assembly should be inspected.
(See page RS±16, RS±29, RS±41, RS±54, RS±60, RS±65 and RS±70)

Never use SRS parts from another vehicle. When replacing parts, replace them with new parts.

Never disassemble and repair the steering wheel pad, front passenger airbag assembly, side
airbag assembly, airbag sensor assembly, front airbag sensor or side airbag sensor assembly
in order to reuse it.

If the steering wheel pad, front passenger airbag assembly, side airbag assembly, airbag sen-
sor assembly, front airbag sensor or side airbag sensor assembly has been dropped, or if there
are cracks, dents or other defects in the case, bracket or connector, replace them with new
ones.

Use a volt/ohmmeter with high impedance (10 kW/V minimum) for troubleshooting the system's
electrical circuits.

Information labels are attached to the periphery of the SRS components. Follow the instruc-
tions on the notices.

After work on the SRS is completed, perform the SRS warning light check (See page DI±626).

If the vehicle is equipped with a mobile communication system, refer to the precaution in the
IN section.
CAUTION:

Work must be started 90 seconds after the ignition switch is turned to the ºLOCKº position and
the negative (±) terminal cable is disconnected from the battery.
(The SRS is equipped with a back±up power source so that if work is started within 90 seconds
from disconnecting the negative (±) terminal cable of the battery, the SRS may be deployed.)

When the negative (±) terminal cable is disconnected from the battery, the memory of the clock
and audio system will be canceled. So before starting work, make a record of the contents mem-
orized in the audio memory system. When work is finished, reset the audio systems as they
were before and adjust the clock. To avoid erasing the memory in each memory system, never
use a back± up power supply from outside the vehicle.

Before repairs, remove the airbag sensor if shocks are likely to be applied to the sensor during
repairs.

Do not expose the steering wheel pad, front passenger airbag assembly, side airbag assembly,
airbag sensor assembly, front airbag sensor or side airbag sensor assembly directly to hot air
or flames.

TSB
The cassette tape head and capstan should be cleaned regularly to prevent poor sound
quality and/or cassettes from jamming.
The following conditions can easily be avoided by regularly cleaning the head with a tape
cleaner and only using good quality cassettes.
Since the tape head contacts the cassette tape, the tape head accumulates metal oxides
and dirt particles from the tape. In time, a layer of dirt forms on the tape head resulting in
poor transfer of information between the tape and the tape head. This typically causes a
reduction of the higher frequencies or a reduction of the brightness in sound quality.
Tape speed is controlled by the tape capstan and pinch rollers. If the capstan and pinch
rollers accumulate dirt, the tape may slip causing the music to play too fast or too slow.
Dirt can make the capstans sticky, causing the tape to become entangled in the cassette
mechanism. This can cause the cassette to become jammed in the player.
To reduce the occurrence of these conditions, the following approved cassette cleaners are
available through the non±parts system (Material Distribution Center).

Vehicles with power antennas may exhibit audible electrical noise on weak AM stations when
various electrical accessories (turn signals, rear defogger, cruise control, brakes, etc.) are operated.
Poor antenna grounding can cause this condition.
To eliminate or reduce the intensity of the noise, use the following repair procedure:

AUDIO
AU002±96
ALL MODELS
REPAIR PROCEDURE:
1. Tune the radio to a strong, static±free AM
station and slowly move the tip of the
antenna mast forward and back
approximately 2 inches (Fig. 1). If static
noise is not heard, go to Step 2. If static
noise is heard during antenna movement,
replace the antenna mast and go to Step 3.

NOTE:Do not touch the antenna mast with
your bare hands. Use a glove or
nonmetallic object to move the
antenna. (If you touch the antenna
with your hands, you will change the
antenna sensitivity).
2. Remove the antenna mast and inspect the
base of the mast for corrosion and damage
(Fig. 2). Clean with 1500 grit sandpaper.
3. Remove the antenna assembly and inspect
the inner fender around the antenna hole
for corrosion (Fig. 3). Clean with 1500 grit
sandpaper.
