WIRELESS DOOR LOCK CONTROL SYSTEM
INSPECTION PROCEDURE
HINT:
The switch described in this text is a switch for transmitting signals which is built in the door control transmit-
ter.
1
CHECK WIRELESS DOOR LOCK CONTROL FUNCTIONS (See page 73-8)
NG Go to step 2
OK
NORMAL
2
REPLACE TRANSMITTER BATTERY WITH NORMAL ONE
(a) After replacing the transmitter battery with a new or normal one, check that the doors can lock and
unlock by using the transmitter LOCK/UNLOCK switch.
NG Go to step 3
OK
REPLACE TRANSMITTER BATTERY
3
CHECK WIRELESS DOOR LOCK CONTROL FUNCTIONS
(a) Check if UNLOCK-LOCK operates in standard operation.
NOTICE:
Standardized test procedure: Press the transmitter switch for 1 second, directing the beam to driver
side door outside handle from a distance of 1 m (39.4 in.). The transmitter should be pointed directly
at the door handle, i.e at 90
_ angle to the vehicle body.
NG REPLACE DOOR CONTROL TRANSMITTER
OK
4
CONFIRM ROOM LAMP ON
(a) Check that the wireless door lock buzzer sounds.

SWITCH TO SELF-DIAGNOSTIC MODE
(a) Switch to self-diagnostic mode by operating the ignition key cylinder.
(1)
Put the vehicle under the vehicle’s initial condition (See page 73-8), insert the key into the igni-
tion key cylinder and remove it.
(2)
Within 5 seconds after the key is removed (step 1), insert the key into the ignition key cylinder
(ignition key OFF) and perform the following once: Turn the ignition switch to ON and return it
to OFF.
(3)
Within 30 seconds after the ignition switch is returned to OFF (step 2), perform the following 9
times: Turn the ignition switch to ON and return it to OFF.
NOTICE:
If operation has failed, the system will return to normal mode.
HINT:
F
Turning the ignition switch ON after step 3 has been completed will end self-diagnostic mode.
F
Do not lock or unlock doors during self-diagnostic mode.
(b) Check that the system has switched to self-diagnostic
mode by the blinking frequency of the room lamp.

CHECK BY SELF-DIAGNOSTIC MODE
(a) Inspect the diagnosis outputs when the door control transmitter switch is held down (The diagnosis
outputs can be checked with the outputs of the room lamp).
HINT:
F
In the case of a reception of the normal wave of the door LOCK and UNLOCK switch (room lamp blink-
ing), go to step A.
F
In the case of an unmatching recognition code (room lamp ON), go to step B.
