(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
