INSPECTION PROCEDURE 2
All of the doors can be locked and unlocked using the
transmitter, but the room lamp does not flash or
illuminate. (However, the room lamp operates normally
when the doors are opened and closed.)
Probable cause
If the room lamp operates normally when the doors are opened and closed, the cause
of the problem may be a malfunction of the receiver or a malfunction of the harness
between the room lamp the receiver.

SECRET CODE REGISTRATION METHOD
Each individual secret code is registered inside
the transmitter, and so it is necessary to register
these codes with the EEPROM inside the receiver
in the following cases.

When either the transmitter or receiver is
replaced;

If it appears that a problem is occurring because
of faulty registration of a code.
A maximum of two different codes can be stored
in the memory area of the EEPROM (two different
transmitters can be used). When the code for the
first transmitter is registered, the previously-regis-
tered codes for two transmitters are cleared.
Therefore, if you are using two transmitters or are
adding a second transmitter, the codes for both
transmitters must be registered at the same time.
Before beginning with the registration, check that
the doors lock normally when the key is used.
1. Connect the MUT-II to the diagnosis connector.
NOTE
This will connect terminal (1) of the diagnosis
connector to earth, and the system will be in
secret code registration standby mode.
Caution
Always turn the ignition switch to OFF before
connecting and disconnecting the MUT-II.
2. Close all the doors.
3. Turn the ignition switch to ACC and then back
to OFF.NOTE
The doors will lock and unlock once at this
time and the system will switch to registration
mode.
4. Press the transmitter switch, and then press
it two times within 10 seconds of the first press.
This will register the code.
5. After registration is completed, the doors will
be automatically locked and unlocked once.
6. If you are using two transmitters or have added
a second transmitter, the same registration
procedure should be carried out for the second
transmitter, and it should be carried out within
one minute after registration of the code for
the first transmitter has been completed. After
the second registration is completed, the doors
will be automatically locked and unlocked once.
7. Registration mode will be cancelled if one of
the following conditions is met.

When the secret codes for two transmitters
have been registered;

When 1 minute has passed after
registration mode started;

If the MUT-II is disconnected (the earth
connection is broken);

If the ignition switch is turned to ON;

If any of the doors are opened;
8. After registration is completed, carry out the
following to check if the keyless entry system
is operable properly.

Remove the ignition key.

Close all the doors.

BODY – Sunroof42-11
Inspection Procedure 2
The motor does not reverse its direction when a load of
140 N or more is applied while the sunroof is closing.
Probable cause
The sunroof-ECU monitors the load conditions from the amount of current flowing
to the motor. If more than the constant amount of current is flowing, the direction
of motor operation is reversed to prevent jamming.
If the motor does not reverse direction even when an excessive load is being applied,
the cause may be a malfunction of the sunroof-ECU.
Malfunction of sunroof-ECU
Replace the sunroof-ECU.
Inspection Procedure 3
The timer does not operate for 30 seconds after the
ignition switch is turned to OFF.
Probable cause
The sunroof-ECU has a timer function which operates for 30 seconds after the ignition
switch is turned to OFF. If the timer does not operate, the cause may be a malfunction
of the sunroof-ECU or of the wiring harness or connector.
Malfunction of sunroof-ECU

Inspection Procedure 4
Opening or closing of the sunroof is possible for 30
seconds after turning the ignition switch to OFF, but the
timer function is not extended when the driver’s side door
is opened within this period.
Probable cause
The sunroof timer operation period is extended when an on signal is output from
the driver’s-side door switch. Because of this, if the timer operation period is not
extended, the cause may be a malfunction of the door switch input circuit.
