OPERATION IN SYSTEM OPERATION MODE
When the transmission switch is pressed once, three
identical codes are transmitted from the transmitter.’

The secret code is decrypted by the comparator circuit

in the receiver which compares the code with the

code stored in the receiver. When the transmitted
code coincides with the stored code, the receiver
sends a door unlock signal or door lock signal to

the ETACS-ECU.

In response to the signal, the doors are locked or
unlocked. When the door lock switch in the door lock

actuator is caused to be ON (unlock) or OFF (lock),
the receiver causes the dome light to flash or steadily

TIMER LOCK FUNCTION

If none of the doors is opened in less than 30 seconds

after the doors have been unlocked by the
entry system, the receiver will automatically output
a door lock signal to the ETACS-ECU to re-lock the
doors.
This function prevents accidental unlocking of the
doors that may be caused by an unintentional opera-

tion of the transmitter.

Operation Inhibit Conditions
In the following cases, operation of the system is
inhibited.

l

When a code different from the one stored in
the receiver is received 30 consecutive times
in a minute, operation of the system is inhibited
for 10 minutes.

l

When the ignition key is in the ignition switch
(detected by the key reminder switch)

l

When any of the doors is not fully closed (door

OPERATION IN CODE REGISTRATION MODE
(PROGRAMMING)
When the code registration switch is in the

or

position, the receiver enters the registration mode where it
stores the first received secret code in the EEPROM.

Two different secret codes can be stored with the switch in
the

and

positions. Therefore, the user can use

two transmitters.

Electric Sunroof

l

If an obstruction interferes with the sliding open
motion, the roof lid glass immediately stops.

l

If an obstruction interferes with the sliding close

or tilt down motion, the roof lid glass will auto-

matically reverse.

l

Even after the ignition switch has been placed
at OFF, the sunroof can be operated for 30

seconds. When a door is opened during the
period, the sunroof can be operated for another
30 seconds from that time.

SUNROOF CONTROL SYSTEM

The motor driven outer slide glass sunroof tilt-up

mechanism is an option for all models. This glass
sunroof provides a well-lighted, open environment
even with the roof lid glass in the fully closed state.

The sun roof provides the following features.

To slide open or close the sunroof or tilt it up
or down, you don’t have to continue to press
the switch like the conventional one. The sunroof
operates at the touch of the switch.

If motion of the roof lid glass is interrupted during

a tilt-up operation, the tilt up operation does

not stop until the roof lid glass reaches the fully

tilted up state.
