(PREPARE NEW OR NORMAL TRANSMITTER OF THE SAME
TYPE VEHICLE)
CIRCUIT DESCRIPTION
The door control receiver receives a signal from the transmitter and sends this signal to the integration relay.
Then, the integration relay controls door operation by sending a door LOCK/UNLOCK signal and a luggage
door (back door) unlock signal to each door lock motor.

INSPECTION PROCEDURE
HINT:
The switch described in this text is a switch for transmitting signals, whi\
ch is built in the door control transmit-
ter.
1CHECK WIRELESS DOOR LOCK CONTROL FUNCTIONS (See page 73±15)
NG Go to step 2
OK
NORMAL
2 CHECK THAT TRANSMITTER LED LIGHTS UP
(a) Check that the transmitter LED lights up 3 times when the switch is pres\
sed 3 times. NG Go to step 8
OK
3 CHECK WIRELESS DOOR LOCK CONTROL FUNCTIONS (STANDARD OPERA- TION)
(a) Check if the UNLOCK±LOCK operates in standard operation.
NOTICE:
Standardized test procedure: Press the transmitter switch for 1 second, directing the beam to driv-
er 's door outside handle from a distance of 1 m (39.4 in.). The transmitte\
r should be pointed directly
at the door handle, i.e. at 90
angle to the vehicle body.
NG Go to step 4
OK
REPLACE TRANSMITTER SUB±ASSY MODULE SET DOOR CONTROL
4 CONFIRM ROOM LAMP ON
(a) Check that the room lamp lights up.
HINT:
When the room lamp does not light up, proceed to the self±diagnostic mode\
after repairing the room lamp.

5 SWITCH TO SELF±DIAGNOSTIC MODE
(a) Switch to the self±diagnostic mode by operating the ignition key cylinder. (1)Put the vehicle under the vehicle's initial condition (See page 73±15), 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 int\
o 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:

Turning the ignition switch ON after step 3 has been completed will end t\
he self±diagnostic mode.

Do not lock or unlock doors during the self±diagnostic mode.
(b) Check that the system has switched to self±diagnosticmode by the blinking frequency of the room lamp.
NG Go to step 10
OK

6 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:

In the case of a reception of the normal wave of the door LOCK, UNLOCK switch or luggage door (back
door) unlock switch (room lamp blinking), go to step A.

In the case of an unmatching recognition code (room lamp ON), go to step B.

In the case of no diagnosis outputs (room lamp OFF), go to step C.
