PRECAUTION
1. PRECAUTION OF HEADLIGHT BULB REPLACEMENT
(a) When any defects such as deformation, crack, dent, chipping, etc. are identi\
fied on the discharge
headlight (especially, on the light control ECU), replace it with a new one.
(b) Even if the operation seems to be normal, the fail±safe function may \
be defective.
(c) Be careful not to scratch on drop bulbs of the discharge headlamp and halo\
gen bulbs (for headlamp and fog lamp), as they have pressurized gas inside and can be easily broke\
n.
(d) Touching the HV socket of the discharge headlight with the headlight dimmer swit\
ch ON could gener- ate momentary high voltage of 20,000 V and lead to a serious injury.
(e) Never connect a tester to the high voltage socket of the discharge headlight \
for measurement, as this
leads to a serious injury because of high voltage.
(f) When performing operation related to the discharge headlight, keep it away from water including rain, turn off the light control switch, and disconnect the battery terminal and the \
connector of the light control
ECU in advance to avoid electric shock.
(g) When performing operation related to the discharge headlight, start it after\
assembling is completed
and never turn the lights on without a bulb installed.
(h) Do not turn the discharge headlight on using another power source except\
vehicle's.

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 kis
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).

CK switch, UNLOCK switch and
luggage door (back door) unlock switch) which is built in the door control t\
ransmitter.

All the functions listed below must be checked in comparison with the re\
mote control operational area.
(a)Put the vehicle under the conditions that allow the wireless control fun\
ction to be operated (See PRE-
CAUTION on page 73±14).
(b) Check the basic function. (1) Check whether the LED of the transmitter lights up 3 times when each switch i\
s pressed 3 times.
HINT:
If the LED does not light up when the switch has been pressed 3 times or more, it may have a dead bat\
tery.
(2) Check that all the doors including the luggage door (back door) lock when t\
he LOCK switch ispressed (However, this will not happen when any door is open).
(3) w/ Double locking system: Check that the double locking system is set when the LOCK switch is pressed within 5 seconds
after the above step (However, the double locking system is not applicable to the luggage door
(back door)).
CAUTION:
Never activate the double locking system when there are people in the vehicle, because all the doors
cannot be opened from inside the vehicle with the system on. If you lock\
the doors by accident, push
UNLOCK switch of the door control transmitter. (4) Check that all the doors including the luggage door (back door) unlock when\
the UNLOCK switchis pressed. Also, check that the double locking system is canceled at th\
e same time.
(5) Check that the luggage door (back door) unlocks when the luggage door (bac\
k door) unlock
switch is pressed.
HINT:
The UNLOCK switch and luggage door (back door) unlock switch can unlock t\
he doors even when any door
is open.
(c) Check the chattering prevention function. (1) Check that the corresponding operation occurs only once, and not repeated continuously whilethe switch is held down. However, when the switch is operated repeatedly at 1 second intervals,
check that the corresponding operation is carried out.
(d) Check the automatic locking function. (1) Check that all the doors including the luggage door (back door) lock automatically as long asnone of them have been opened or locked within approx. 30 seconds after they\
are unlocked
by pressing the switch.
(2) Check that the automatic locking function does not operate when any door incl\
uding the luggage
door (back door) has been opened or all of them have been locked within ap\
prox. 30 seconds
after they are unlocked by pressing the switch.
(e) Check the switch operation fail±safe function. (1) Check that the doors can not be locked by the switch while the key is in the \
ignition key cylinder.
However, this does not apply when the system is in the recognition code registra\
tion mode.
(f) Check the repeat function. (1) Check that all the doors attempt to automatically lock once again 1 second af\
ter the LOCK switchhas been pressed while the movement of the driver side door control knob, which is in the un-
locked state, is being restricted.
