ON±VEHICLE INSPECTION
Make the vehicle in the initialized condition:
The initialized condition is the condition when the following conditions are satisfied.
(1) Key plate has not been inserted in the ignition key cylinder.
(2) All the doors are closed. (Door warning light is OFF.)
(3) All the doors are locked.
Under the standard operation, when repeating UNLOCK and LOCK switch 3 times or more alternately, check the
UNLOCK±LOCK operation from 3rd time onward.

Following procedures are standard operation.
(1) Keep about 1 M away to the right direction from the outside handle of a driver's seat.
(2) Face the transmitter toward the vehicle and press one of transmitter switches for about 1 sec.


As of the security function, even the wireless function is normal, there may be the case that only UNLOCK opera-
tion will not work.

As of the body customize function, if ºoperation twiceº has been set using hand±held tester, only driver's seat
is unlocked by unlock operation performed once.
Normal


Operative distance may differ according to
an operator, the way of holding the transmitter
or position.

Because weak electric wave is used, when
there is strong wave or noise in the used
frequency, operation distance might be
shortened.
No Yes
Only wireless function (Remote control) will not operate.
(If a new transmitter or a transmitter of the same type that works properly with the vehicle is not available.)

INSPECTION
1. INSPECT WIRELESS DOOR LOCK TRANSMITTER
OPERATION
HINT:
Refer to ºWireless door lock control transmitter battery replace-
mentº on page BE±103.
(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 the battery (±) to the bottom
terminal, then apply 3 V voltage to the transmitter.
(d) In the location where transmitter is approx. 1 M away from
the driver's outside handle in the right direction, check
transmitter operation while pressing transmission switch
on the side of the transmitter body.
Standard:
Remote control of the vehicle door lock can be operated.
HINT:

The minimum operation distance differs according to op-
erator, the way of holding the transmitter, and location.

As a weak wave is used, operating distance might be
shortened when noise is detected in a strong wave or a
used frequency.
(e) Install the battery (lithium battery).
(f) Install the cover so that a rubber cover is not distorted or
slipped off.
