Replace the transmitter battery with a new or normal
one and check UNLOCK±LOCK function works under
the standard operation.
The battery should be replaced by only the shops with
sufficient skill as new or normal battery is necessary.
Battery quality can be judged by checking the rem-
nant volume of the battery.

Make the vehicle be in the initialized condition.
Enter into the self diagnostic mode.
If operating door control receiver in the order of 1 through 2, the mode turns to diagnostic mode.
(1) Insert the key plate in the ignition key cylinder and pull out, then insert it again and turn ignition switch
OFF " ON " OFF once within 5 seconds after pulling out.
(2) After completing the procedure within 30 seconds, turn the ignition switch OFF " ON " OFF 9 times.
HINT:
In the case that either (1) or (2) condition is not satisfied, transfer to normal mode.
When completing self diagnostic mode, turn the ignition switch ON.

INSPECTION
1. INSPECT WIRELESS DOOR LOCK TRANSMITTER
OPERATION
HINT:
Refer to ºWireless door lock control transmitter battery replace-
mentº on page BE±161.
(a) Using a screwdriver, remove the screw 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, 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 the transmitter, 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 O±ring is not distorted or slipped off.
(g) Using a screwdriver, tighten the screw.

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 screws and 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

HINT:
When the temperature of the battery is low, the judge can
not be made correctly.
When the outcome of the test is less than 2.1 V, conduct
the test again after leaving the battery in the place at 18
°C for more than 30 minutes.
By auto power off function, the voltage becomes no load
voltage (more than 2.5 V) condition 0.8 seconds after the
switch was pressed.
Make sure to read the voltage before of it.
High voltage might be shown 1 to 2 times after leaving the
battery, judge should be made with the voltage shown at
the 3rd time or later.
(g) Disconnect the lead.
(h) Set the battery (lithium battery) in the transmitter.
(i) Install the cover, so that the O±ring is not distorted or
slipped off.
(j) Using a screwdriver, tighten the screws.
3. INSPECT WIRELESS DOOR LOCK BUZZER OPERA-
TION
Connect the positive (+) lead from the ohmmeter to terminal 1
and the negative (±) lead to terminal 2, and measure resistance
of approx. 1 kW.
If resistance is not as specified, replace the buzzer.

REPLACEMENT
1. REPLACE TRANSMITTER (LITHIUM) BATTERY
NOTICE:
Special caution should be taken for handling each compo-
nent as they are precision electronic components.
(a) Using a screwdriver, remove the screw and cover.
NOTICE:
Do not pry out the cover forcibly.
HINT:
Push the cover with a finger as shown in the illustration, so that
there becomes clearance, then pry out the cover from that
clearance.
(b) Remove the transmitter.
(c) Using a screwdriver, remove the 2 screws and cover.
(d) Remove the battery (lithium battery).
NOTICE:
Do not push the terminals with a finger.
If prying up the battery (lithium battery) forcibly to re-
move, the terminals are deformed.
(e) Install a battery (lithium battery) as shown in the illustra-
tion.
NOTICE:
Face the battery upward. Take care not to deform the termi-
nals.
(f) Check that O±ring is not distorted or slipped off, and
install the cover.
(g) Using a screwdriver, tighten the 2 screws.
NOTICE:
When the shrews are tightened loosely, it might cause
faulty contact of battery (lithium battery) and terminals.
(h) Assemble the transmitter to the key plate and the cover.
(i) Using a screwdriver, tighten the screw.
