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.

2) Cause of vibration/pulsation problems
3) Advantages of using an on±car brake lathe
4) Rotor replacement and off±car brake lathe procedure
1) SYMPTOMS OF BRAKE VIBRATION AND PULSATION
Brake vibration problems generally involve one or both of two phenomena: body vibration and/
or pedal pulsation.
A. BRAKE VIBRATION
Applying brakes causes vibration to occur in the instrument panel, steering column, steering
wheel, and/or body of the vehicle (See Figure 1 below).

TSB REVISION NOTICE:
The information updated in this TSB is red
and underlined.
The On±Board Diagnostic (OBDII) system is designed to monitor the performance of
emission±related components and report any detected abnormalities in the form of
Diagnostic Trouble Codes (DTCs). Since the various components need to be monitored
during different driving conditions, the OBDII system is designed to run separate
monitoring programs called Readiness Monitors. Many state Inspection and
Maintenance (I/M) programs require that vehicles complete their Readiness Monitors
prior to beginning an emissions test.
The current status of the Readiness Monitors can be seen by using the Toyota Diagnostic
Tester with version 9.0 software (or newer), or a generic OBDII Scantool.
To view the Readiness Monitor status using the Toyota Diagnostic Tester, select ªMonitor
Statusº from the Enhanced OBDII Menu.
A status of ªcompleteº indicates that the necessary conditions have been met to run the
performance tests for the related Readiness Monitor.
The Readiness Monitor will be reset to ªincompleteº if:

ECU has lost power (battery or fuse).

DTCs have been cleared.

The conditions for running the Readiness Monitor have not been met.
In the event that any Readiness Monitor shows ªincomplete,º follow the appropriate
Readiness Monitor Drive Pattern to change the readiness status to ªcomplete.º
Refer to the Readiness Monitor Drive Pattern Application Table to determine which
drive pattern should be followed.
