3. CHECK DIAGNOSIS
(a) Using the hand±held tester, check for DTCs.
NOTICE:
Hand±held tester only:
When the diagnosis system is switched from normal mode to check mode, all the DTCs and freeze
frame data recorded in normal mode are erased. So before switching modes, always check the DTCs
and freeze frame data, and make a note of them.
(1) Prepare the hand±held tester.
(2) Connect the hand±held tester to the DLC3 under the instrument panel lower pad.
(3) Turn the ignition switch ON and push the hand±held tester switch ON.
(4) Use the hand±held tester to check for DTCs and freeze frame data, and make a note of them
(For operating instructions, see the hand±held tester instruction book).
(5) Confirm the details of the DTCs.
(b) Either of the following procedures will erase the DTCs and freeze frame data.
(1) Operating the hand±held tester to erase the codes (See the hand±held tester instruction book
for operating instructions).
(2) Disconnecting the battery terminals or ECU±B fuse.
4. DATA LIST
HINT:
Using the DATA LIST displayed on the hand±held tester, you can read the value of the switch, sensor, actua-
tor, etc. without parts removal. Reading the DATA LIST as the first step of troubleshooting is one way to short-
en the labor time.
(a) Connect the hand±held tester to the DLC3.
(b) Turn the ignition switch ON.
(c) Read the DATA LIST, according to the display on the tester.

AVENSIS REPAIR MANUAL (RM1018E)
INSPECTION
1.INSPECT TRANSMITTER SUB±ASSY MODULE SET DOOR CONTROL
(a)Inspect operation of the transmitter.
(1)Remove the battery (lithium battery) from the transmitter (See page 73±17).
(2)Install a new or normal battery (lithium battery).
HINT:
When a new or normal battery is not available, connect 2 new
1.5 V batteries in a series, connect the battery positive (+) to the
battery receptacle side terminal and battery negative (±) to the
bottom terminal, then apply 3 V of voltage to the transmitter.
(3)In a location that is approx. 1 m (3.28 ft) away from the driver side ou\
tside door handle in the right direction, point the key plate of the transmitter at the vehicle and che\
ck operation of the transmit-
ter by pressing the transmission switch on the transmitter body.
Standard:
The door lock can be operated via the remote control.
The LED lights up more than once.
HINT:

The minimum operational distance differs, depending on the operator, the way the transmitter is held,
and the location.

Since the transmitter uses faint electric waves, the operational distanc\
e might be shortened if noise
or strong electric wave occurs in the area where the frequency is used.
(4)Install the battery (lithium battery).
(b)Inspect the battery capacity.
HINT:

The capacity of the battery can be determined only when the battery is inst\
alled in the transmitter. For
a lithium battery used in the transmitter, a voltage of more than 2.5 V is shown on the tester until the
energy is completely consumed, while no battery is installed in the transmitte\
r. Therefore, it is neces-
sary to measure the voltage while the battery is installed in the transmitte\
r (a resistance of 1.2 k is
applied to the battery) when checking the amount of energy left in the \
battery.

If the transmitter is faulty, the amount of energy left in the battery might not be checked correctl\
y.
(1)Remove the battery (lithium battery) from the transmitter (See page 73±17).

AVENSIS REPAIR MANUAL (RM1018E)
WIRELESS DOOR LOCK CONTROL SYSTEM
PRECAUTION
1. NOTICES WHEN CHECKING
(a) The wireless door lock remote control function operates only when the following 3 conditions are met.
(1) All the doors are closed.
(2) No key is inserted in the ignition key cylinder.
(3) The power door lock system operates normally.
HINT:
The door UNLOCK and luggage door (back door) UNLOCK functions operate even when a door is open.
(b) The wireless door lock remote control operational area differs depending on the situation.
(1) The operational area differs depending on the operators and the ways the transmitter is held.
(2) In certain areas, the remote control function will only operate partially for the operational area
will be reduced due to the vehicle body shape and the influence of the surrounding environment.
(3) Since the transmitter uses faint electric waves, strong electric waves or noise in the frequency
used may reduce the operational area or the remote control may not function.
(4) When the battery weakens, the operational area is reduced or the remote control may not func-
tion.
HINT:
If the door control transmitter has been left in a place that is exposed to the direct sunlight, such as on the
instrument panel, it may cause the battery to weaken or cause other such problems.

(d) Check the illumination function.
(1) Set the room light switch in the DOOR position.
(2) With all doors locked, check that all doors unlock when the driver side door lock cylinder is turned
to UNLOCK using the key and that the room right turns on.
(3) Check that the room light turns off in approx. 15 seconds after the doors have not been opened
for a while.
3. w/ Double lock:
CHECK DOUBLE LOCKING FUNCTION SYSTEM
(a) Check that the double locking system is set to ON.
(1) Open all the windows.
(2) Turn the ignition switch to LOCK and remove the key.
(3) Open and close the driver side door, and make sure that all doors including the back door are
closed securely.
(4) Push the LOCK switch on the wireless transmitter twice within 5 seconds, and check that the
hazard warning lights flash once at this time to show that the system is set.
(5) Try to unlock all doors using the inside handle of the vehicle, and check that none of the doors
unlock.
NOTICE:

The double locking system cannot be set to ON without using the wireless transmitter.

The double locking system operation is not related to the back door.
(b) Check that the double locking system is set to OFF.
(1) Push the UNLOCK switch on the wireless transmitter while the double locking system is ON, and
check that the hazard warning lights flash twice at this time to show that the system is set to OFF.
(2) Check that the doors can be opened both by the inside handle and the outside handle.
NOTICE:
If the battery of the wireless transmitter is dead, only the driver side door can be opened using the
key. However, the theft deterrent system still remains on. Therefore, be aware that the theft alarm
is set off when the door is opened without the use of the wireless transmitter.
