INTERIOR
 WIRELESS DOOR LOCK REMOTE CONTROL SYSTEM
A wireless door lock remote control system is available as an option on the LE grade model and is standard
equipment on the XLE grade model. With the wireless door lock remote control system, all the doors can be locked
and unlocked by signals emitted by the transmitter.
A 2±step unlock function is provided. When the unlock switch of the transmitter is pressed once, only the driver's
door is unlocked. When it is pressed twice, all the doors are unlocked.
A panic switch is provided in the transmitter to force the theft system by operating the horn, headlight and taillight.
A wireless door lock ECU with EEPROM (Electrical Erasable Programmable ROM) is used so that the transmitter
recognition code can be easily reprogrammed.
 THEFT DETERRENT SYSTEM
A theft deterrent system is used to prevent vehicle theft. When the system is set, the horn and headlights operate
if the door, hood or trunk is forcibly opened.
The audio system also has an anti±theft system whereby the radio and cassette deck is disabled if the radio body
is stolen from the vehicle.

DESCRIPTION
The new Camry includes the accessory systems shown in the below.
System
Outline
Power Window System
The power window system includes one±touch auto down and key±off opera-
tion functions. The one±touch auto down function automatically opens the
driver 's door window fully. The key±off operation function makes it possible
to operate the power windows for approximately 45 seconds after the igni-
tion key is turned to the ACC or LOCK position, if the front doors are not
opened.
The basic construction and operation of this system are the same as in the
previous model.
Door Lock Control System
This system has a ªkey±linked lock and unlock functionº and a ªkey±confine
prevention functionº. All doors can be locked and unlocked simultaneously
by a key operation at the front right or left foor. (The key needs to be oper-
ated twice to unlock all the doors at the driver's door.) If the door lock opera-
tion is performed when one of the front doors is open and the ignition key is
inserted in the key cylinder, doors are unlocked automatically to prevent the
ignition key from being left inside the vehicle.
The basic construction and operation are the same as in the previous model.
Wireless Door Lock Remote Con-
trol System
A remote control system in which the lock and unlock functions of all doors
and panic alarm function can be controlled by the signals emitted from a
transmitter is adopted. The transmitter is also provided with a 2±step unlock
function to unlock all the doors by pressing the switch twice.
The basic construction and operation are the same as in the '96 Avalon.
However, certain functions have been changed. For details, see page 107.
Theft Deterrent System
When an attempt is made to forcibly enter the vehicle or open the hood or
trunk lid without a key, or when the battery terminals are removed and re-
connected, this system sounds the horn and flashes the headlights and tail-
lights for about 1 minute to alert the owner. At the same time, it locks all the
doors and electronically disconnects the starter.
The basic operation is the same as in the '96 Avalon.
Power Seat
As in the previous model, the front seats are power assisted by electric mo-
tors so that the seat positions can be adjusted easily by a simple switch op-
eration.
The basic construction and operation are the same as in the previous model.

110BODY ELECTRICALÐACCESSORIES
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).

ºPANICº SWITCH
Pushing the ºPANICº switch blows the
horn intermittently and flashes the
headlights and tail lights.
The ºPANICº switch is used to deter ve-
hicle theft when you witness anyone at-
tempting to break into or damage your
vehicle.
The alarm will last for one minute. To stop
alarm midway, push the ºPANICº switch
once again, unlock any door with the key
or transmitter, or turn the ignition key from
the ºLOCKº to ºONº position.
The ºPANICº mode does not work when
the key is inserted in the ignition switch.WIRELESS REMOTE CONTROL TRANS-
MITTER
The wireless remote control transmitter is
an electronic component. Observe the fol-
lowing instructions in order not to cause
damage to the transmitter.

Do not leave the transmitter on places
where the temperature becomes high
such as on the dashboard.

Do not disassemble it.

Avoid knocking it hard against other
objects or dropping it.

Avoid putting it in water.
You can use up to 2 wireless remote con-
trol transmitters for the same vehicle.
Contact your Toyota dealer for detailed
information.
If the wireless remote control transmitter
does not actuate the doors or alarm, or
operate from a normal distance:

Check for closeness to a radio trans-
mitter such as a radio station or an
airport which can interfere with normal
operation of the transmitter.

The batteries may have been con-
sumed. Check the batteries in the
transmitter. To replace the batteries,
see ºReplacing transmitter batteriesº.REPLACING TRANSMITTER BATTERIES
For replacement, use DURACELL
) DL2016
batteries or equivalent.
CAUTION
Special care should be taken that
small children do not swallow the re-
moved transmitter batteries or compo-
nents.
NOTICE
When replacing the terminal batteries,
be careful not to lose the compo-
nents.
Replace the transmitter batteries by the
following procedures:

2. In front of the vehicle, pull up the
auxiliary catch lever and lift the
hood.3. Hold the hood open by inserting the
support rod into the slot.
Before closing the hood, check to see that
you have not forgotten any tools, rags,
etc. and return the support rod to its
clip
this prevents rattles. Then lower the
hood make sure it locks into place. If
necessary, press down gently on the front
edge to lock it.
CAUTION
After inserting the support rod into
the slot, make sure the rod supports
the hood securely from falling down
on to your head or body.
Theft deterrent system
To deter the vehicle theft, The system
is designed to give an alarm if any of
the doors, trunk or hood is forcibly un-
locked or the battery terminal is discon-
nected and then reconnected when the
vehicle is locked.
The alarm blows the horn intermittently
and flashes the headlights and tail lights.

B HOW TO USE THIS MANUAL
The ground points circuit diagram shows the connections from all major parts to the respective ground points. When
troubleshooting a faulty ground point, checking the system circuits which use a common ground may help you identify
the problem ground quickly. The relationship between ground points (
EA, IB and IC shown below) can also be
checked this way.

The ºCurrent Flow Chartº section, describes which parts each power source (fuses, fusible links, and circuit breakers)
transmits current to. In the Power Source circuit diagram, the conditions when battery power is supplied to each system
are explained. Since all System Circuit diagrams start from the power source, the power source system must be fully
understood.
