THEFT DETERRENT SYSTEM
1. General
The theft deterrent system uses the door lock control system components and some other parts. When
somebody attempts to forcibly enter the vehicle or open the engine hood or luggage compartment door
without a key, or when the battery terminals are removed and reconnected, the theft deterrent system
sounds the vehicle's horn, security horn and flashes the headlights, taillights, hazard lights and interior
light for about one minute to alert. At the same time, it locks all the doors.
The control of this system is effected by the body ECU.

HINT:
Refer to ºWireless door lock control receiver and transmitter re-
placementº on page BE±87.
(a) Using a screwdriver, remove and cover.
(b) Remove the battery (lithium battery).
(c) Install a new or normal battery (lithium battery).
HINT:
When a new or normal battery can not be obtained, connect 2
new 1.5 V batteries in series, connect the battery (+) to the bat-
tery receptacle side terminal and battery (±) to the bottom termi-
nal, then apply 3 V voltage to the transmitter.
(d) In the location where is approx. 1 M away from driver's
outside handle in the right direction, and check the trans-
mitter operation when pressing transmission switch on
the surface of the transmitter body.
Standard:
Remote control of vehicle door lock can be operated.
HINT:

The minimum operation distance differs according to op-
erator, the way of holding, and location.

As weak wave is used, operation distance might be short-
ened when noise is detected in strong wave or used fre-
quency.
(e) Install the battery (lithium battery).
(f) Install a cover so that rubber cover is not distorted or
slipped off.

2. CHECK BATTERY CAPACITY
HINT:

Make sure to use the TOYOTA electrical tester.

With the battery unloaded, judge can not be made wheth-
er the battery is available or not on the test.

When the transmitter is faulty, the energy amount left in
the battery might not be checked correctly.

On the lithium battery used for the transmitter, the voltage
more than 2.5 V with the battery unloaded is shown on the
tester until the energy is completely consumed.
Accordingly when inspecting the energy amount left in the
battery, it is necessary to measure the voltage when the
battery is loaded. (1.2 kW).
(a) Remove the cover using a (±) driver.
(b) Remove the battery (lithium battery) from the transmitter.
(c) Connect the lead to the (±) terminal of the transmitter and
install the battery.
(d) Connect the (+) tester to the (+) battery (lithium battery),
and (±) tester to the lead respectively.
(e) Press one of the transmitting switches on the transmitter
for approx. 1 second.
(f) Press the transmitting switch on the transmitter again to
check the voltage.
Standard: 2.1 V or more
