 WIRELESS DOOR LOCK REMOTE CONTROL SYSTEM
1. General
The wireless door lock remote control system is a conventint system for locking and unlocking all the doors at a
distance.
The basic construction and operation of this system are the same as in the '96 Avalon. However, the following items
have been changed.
The trunk lid open operation, which is provided on the '96 Avalon, has not been adopted.
A panic alarm operation, which activates the alarm of the theft±deterrent system, has been newly adopted.
For ease of verification of the operation of this system, the parking lights and taillights flash to inform that the
operation has been completed.

Panic Alarm Operation
When the ªpanicº switch of the transmitter is pushed, the theft deterrent system sounds the horns and flaashes the
headlights and taillights. To stop the alarm of the theft deterrent system that was triggered through this operation, push
the transmitter's ªunlockº switch or ªpanicº switch again.
Operation Verification Light Function
When the doors are locked by the transmitter switch
operation, the parking light and taillight flashes
once to confirm that the operation has been
completed.
Similarly, the parking light and taillight flashes
twice when the doors are unlocked.
Light Flash Patterns
Transmitter Recognition code Registration Function
As in the '96 Avalon, the recognition code for each transmitter is registered in an EEPROM contained in the wieless
door lock ECU. Up to 2 different recognition codes can be resistered in teh EEPROM. The procedure for registering
a registration code is the same as that used in the '96 Avalon.
For details of the rrecogition code registration procedure, refer to the 1997 Camry Repair Manual (Pub. No.
RM503U).

 SRS AIRBAG
1. General
The SRS (Supplemental Restraint System) airbag is designed to help lessening the shock to the driver and front
passenger as a supplement to the seat belt. In a collision, the aribag sensor detects the shock and if the front±to±rear
shock is greater than a specified value, the airbags stored in the steering wheel pad for the driver and above the glove
box for the front passenger inflate instantly to help reducing the likelihood of the driver's or front passenger's head
and chest directly hitting the steering wheel or instrument panel.
As in the '96 Avalon, a 1±sensor type airbag system is used, in chich the detection of deceleration during a collision
is accomplished by the airbag sensor enclosed in the airbag snesor assembly.
The airbag system is controlled by the airbag sensor assembly. It has a self±diagnosis function. When it detects a
system malfunction, it lights up the SRS warning light on the combination meter to alert the driver.
The basic construction and operation are the same as in teh '96 Avalon. However, 2 types of the inflator for front
passenger have been adopted in the new Camry: TRW made and Morton made. Also, the construction of airbag sensor
assembly has been changed.

System Diagram
The activation processes of the SRS airbag is as illustrated below.

4. Construction and Operation
Side Airbag Sensor Assembly
1) Description
The side airbag sensor assembly is mounted on the right and left center pillars. It receives signals from
the side airbag sensor enclosed in the side airbag sensor assembly and judges whether the side airbag must
be activated or not.
2) Construction and Operation
The side airbag sensor assembly consists of side airbag sensor, safing sensor, etc.
a. Side Airbag Sensor
The side airbag sensor is enclosed in the side airbag sensor assembly based on the acceleration of the
vehicle that occurs during a side collision. The distortion created in the sensor is converted into an elec-
tric signal. This signal is a linear representation of the acceleration rate.
b. Safing Sensor
The safing sensor is enclosed in the side airbag sensor assembly. The sensor turns ON if an acceleration
force that is higher than a predetermined value is applied to the safing sensor as a result of a side colli-
sion.
Airbag Sensor Assembly
1) Description
The airbag sensor assembly is mounted on the center floor under the instrument panel.
When the airbag sensor assembly receives the airbag activation signal from the side airbag sensor assem-
bly, it applies current to the inflator.
Furthermore, the airbag sensor assembly diagnoses a system malfunction of the side airbag system.
This is the same airbag sensor assembly that is used for the
SRS airbag for the driver and front passenger.
2) Construction and Operation
The airbag sensor assembly consists of ignition control circuit, back up power source, diagnosis circuit,
memory circuit, etc.
a. Ignition Control Circuit
The ignition control circuit performs a prescribed calculation based on the signal output by the airbag
sensor and the front airbag sensor. If these calculated values are larger than a predetermined value, it
activates the ignition operation.
b. Back-Up Power Source
The back-up power source consists of a back-up capacitor and a DC-DC converter. In case of a power
system failure during a collision, the back-up capacitor discharges and supplies electric power to the
system. The DC-DC converter is a boosting transformer when the battery voltage drops below a certain
level.
c. Diagnosis Circuit
This circuit constantly diagnoses the system for any malfunction. When a malfunction is detected, it
lights up the
SRS warning light on the combination meter to alert the driver.
d. Memory Circuit
When a malfunction is detected by the diagnosis circuit, it is coded and stored in this memory circuit.

THEFT DETERRENT SYSTEM
1. General
The following changes have been made to the theft deterrent system.
The starter cutoff function has been discontinued with the adoption of the engine immobiliser system.
The illuminating pattern of the indicator light which indicates the condition of the system has been
changed in conjunction with the adoption of the engine immobiliser system.
2. Indicator Light
The '98 Camry has adopted an engine immobiliser system. Accordingly, a single indicator light can display
the conditions of the 2 systems, the engine immobiliser system, and the theft deterrent system. As a result,
the illuminating pattern of the indicator lights are those listed below.

ÐWireless remote control
Locking operation
Unlocking operation
Your vehicle has a wireless remote
control system that can lock or unlock
all the doors, or activate the theft
deterrent system from a distance within
approximately 1 m (3 ft.) of the vehicle.
LOCKING AND UNLOCKING THE
DOORS
To lock and unlock all the doors, push
the switches of the transmitter slowly
and securely.
To lock: Push the ºLOCKº switch. All the
doors are locked simultaneously. At this
time, parking lights, side marker lights and
tail lights flash.
Check to see that the doors are securely
locked.
If any of the doors is not securely closed,
or if the key is in the ignition switch,
locking cannot be performed by the
ºLOCKº switch.
To unlock: Push the ºUNLOCKº switch
once to unlock the driver 's door alone.
Pushing the switch twice within 3 seconds
unlocks all the doors simultaneously. At
this time, parking lights, side marker lights
and tail lights flash twice.You have 30 seconds to open a door after
using the wireless remote unlock feature.
If a door is not opened by then, all the
doors will be automatically locked again.
If the ºLOCKº or ºUNLOCKº switch is kept
pressed in, the locking or unlocking opera-
tion is not repeated. Release the button
and then push again.
