DIAGNOSIS CODE LIST
If there is ºOº in the column of system check, an error can be detected when the mode is switched to
the system check mode.
If there is ºOº in the column of diagnosis mode, each unit is monitoring whether or not it has failure.
In case of detectng failure, it memorizes DTC.

sensitivity knob on the sensor.
(b) This will be determined at what light condition the auto-
matic control will take place.

If response is too quick, turn the knob counterclock-
wise.

If response is too slow, turn the knob clockwise.

(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

2. REPLACE DOOR CONTROL RECEIVER AND TRANS-
MITTER
NOTICE:
When replacing the door control receiver and transmitter,
registration of recognition code is necessary because they
are provided as a single components.
(a) Select the operation mode to perform from the following
operation modes.
Add mode
Rewrite mode
Prohibition mode
Confirmation mode
HINT:
The add mode is used to retain codes already registered
while you register new recognition codes. This mode is
used when adding a transmitter. However, if the number
of registered codes exceeds 4 codes, previously regis-
tered codes are correspondingly erased in order, starting
from the first registered code.
The rewrite mode is used to erase all previously regis-
tered codes and register only new recognition codes.
The prohibition mode is used to erase all registered codes
and cancels the wireless door lock function. Use this
mode when the transmitter is lost.
The confirmation mode is for confirming few many recog-
nition codes ar already registered before you register
additional recognition codes.
(b) Follow the chart on the following page to register the
transmitter recognition code at the wireless door lock con-
trol receiver.
HINT:
When procedure is out of the specified, the operation re-
turns to normal operation.
Maximum 4 recognition codes can be registered.
