WIRELESS DOOR LOCK CONTROL SYSTEM
This system uses the multiplex communication system, so check diagnosis system of the multiplex commu-
nication system before checking the body control system.
Some functions of wireless door lock control system do not operate.
HINT:
Troubleshooting of the wireless door lock control system is based on the premise that the door lock
control system is operating normally. Accordingly, before troubleshooting the wireless door lock control
system, first make certain that the door lock control system is operating normally.
If the trouble still reappears even though there are no abnormalities in any of the other circuits, then
check and replace the Wireless Door Lock Control Receiver as the last step.

INSPECTION
1. INSPECT WIRELESS DOOR LOCK DIAGNOSIS MODE
(a) Start up diagnosis mode.
HINT:
Follow the method below.
(1) Insert the ignition key into the ignition key cylinder.
(2) Remove the ignition key from the ignition key cylin-
der.
(3) Insert the key into the ignition switch.
(4) Turn the ignition switch ON once within 5 sec.
(5) Repeat turning the ignition switch OFF " ON 9
times within 30 sec.
(6) Enter the diagnosis mode, and make sure that the
buzzer sounds.
(b) Finishing the Diagnosis Mode.
During the Diagnosis mode, turn the ignition switch OFF
" ON to go back to the normal mode.
At this time make sure that the buzzer sounds.

(c) Diagnosis Mode Check.
HINT:
Check how the buzzer sounds when pressing each transmitter
switch.
(1) LOCK switch
(2) UNLOCK switch
(3) Luggage door switch
(4) Disagreement of recognition code or rolling code.
HINT:
If (4) is detected in the Diagnosis Check, conduct the recogni-
tion code registration.
(5) No response from the buzzer.
HINT:
Conduct the following checks.
Check the wireless door lock transmitter.
Check the wireless door lock receiver.
2. INSPECT WIRELESS DOOR LOCK TRANSMITTER
OPERATION
HINT:
Refer to ºWireless door lock control receiver and transmitter re-
placementº.
(a) Using a screwdriver, remove the 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, face the key plate of
the transmitter to the vehicle, and check the transmitter
operation when pressing transmission switch on the side
of the transmitter body.
Standard:
Remote control of vehicle door lock can be operated.
LED lights up more than once.
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).
3. 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
