WIRING SYSTEM

Keyless Entry

General Description

This circuit consists of the keyless entry control unit, the
front door lock, & power window switch (RH), the starter
switch, the dome light, the door switch and the tail gate
switch and possible to lock/unlock each door by operation
of transmitter. Basic function of system is as follows.

1. Lock/unlock function

When the Keyless entry control unit receives the
signal from the transmitter, the control unit sends the
locker unlock signal to the front door lock and power
window switch (RH).
Function code (lock or unlock) and proper ID code for
each vehicle are added to the signal. But, when
starter switch is on or any of the doors opens,
lock/unlock function is not unable to work.

2. Answer back function

When receiving the signal from the transmitter, the
keyless entry control unit responds by using the dome
light. In case of being locked, the keyless entry control
unit turns on the dome light at two times (about 0.5
second at each time). In case of being unlocked, it
turns on the dome light at one time (about 3 seconds).

3. Autolock function

After unlock function is done, in case of effecting one
of following conditions within about 30 seconds, the
keyless entry control unit automatically sends the
lock signal to lock each door.

(1) The doors are closed.
(2) Starter key is not inserted
(3) The lock operation is not done by transmitter.
