WASHER INTERLOCKING WIPER
1)
If the Washer SW is ON in the IGN2 SW ON state,
then the Wiper output shall be ON after T1, and
if the Washer SW input is ON for 0.2~0.6 sec-
onds, then the Wiper output shall be OFF after
T3. However, WASHER SW input shall be disre-
garded during the Washer Wiper operating, but
after operating the Washer Wiper, WASHER SW
input shall be accepted first.

If the Washer SW is ON in the IGN2 SW ON state,
then the Wiper output shall be ON after T1, and
if the Washer SW is ON over 0.6 seconds, af-
ter the Washer SW is OFF and the Wiper output
shall be ON for 2.5~3.8 seconds and then, the
Wiper output shall be OFF. However, WASHER
SW input shall be disregarded during the Washer
Wiper operating, but after the Washer Wiper op-
erating, WASHER SW input be accepted first.

ing Wiper output shall be ON. If the Washer SW
is ON for 0.2~0.6 seconds, then the Wiper output
shall be ON once.

VEHICLE SPEED (SENSITIVE TYPE) INT WIPER
According to the vehicle speed, control intermittent
time of the Intermittent Wiper.
• IGN1 SW ON state
• WIPER SW INT state
• INPUT the vehicle speed, intermittent time set
VOLUME value
-
Change the WIPER by calculating the inter-
mittent time according to the vehicle speed.
1)
Input of Vehicle speed
Calculate the vehicle speed by the number of In-
put PULSE for 1 second.
1 [PULSE/sec] = (60[Km/h] × 60[sec]) / (637 × 4
PULSE) ≒ 1.41[Km/h]
2)
Output of Vehicle speed
Count the number of the PULSE for 1 second,
and compare with the former value, and then de-
fine the higher value of the vehicle speeds as the
vehicle speed for intermittent time output.
V = max (Vnew, Vold)
But, Vnew: the present vehicle speed, Vold: the
former vehicle speed

BODY ELECTRICAL SYSTEM
3)
Output of Intermittent time ratio (vehicle speed:
0Km/h)
Calculate the INT time rate by inputting the INT
Time set Volume value (input voltage)
The INT Time Rate is to indicate the position
where the Volume is located from the Slow
(100%) to the Fast (0%) of the Knob. Therefore
the Volume shall be linearly calibrated about the
input voltage.
4)
Output of Standard Intermittent Time
Calculate the intermittent time of the intermittent
time ratio 100% and 0% at the vehicle speed (V)
computed above by linear correction and then,
calculate the standard intermittent time by the
proportional distribution of the intermittent time
ratio computed in (3) item.
• If the variation of the standard intermittent
time is less than 0.3 sec, should not renew
the intermittent time.
• If the standard intermittent time is less than
0.2 sec, continually operate.
• When the INT Time Timer (passed time) is
over 10 seconds, if the vehicle is speeded
up (from 0 km/h to 7km/h and more), then
the Wiper shall be operated.

TAIL LAMP AUTO CUT
After Key IN SW is On, if Tail SW is On, then Key IN
SW shall be OFF; when the driver’s door is opened,
then the Tail Lamp shall be OFF automatically.
Also, in the state that the KEY IN SW is ON, after the
driver’s door is opened, if the KEY IN SW is OFF, then
the Tail Lamp shall be OFF automatically.
After the Auto Cut, if the Tail SW is ON after OFF
again, the Tail Lamp shall be ON, and the Auto Cut
function shall be canceled.
After the Auto Cut, when KEY IN SW is ON again,
TAIL LAMP shall be ON, and the Auto Cut function
shall be canceled.
In the state of the AUTO CUT, if mounting or remov-
ing the BATTERY, then the AUTO CUT state shall be
continued.

HEAD LAMP LOW CONTROL
If HEAD LAMP LOW SW is On in the IGN1 On state,
HEAD LAMP HIGH RELAY shall be ON so that HEAD
LAMP HIGH can be controlled by HEAD LAMP RE-
LAY and M/F SW.

AUTO LIGHT CONTROL
1)
The AUTO LIGHT function shall not be applied in
case of DRL OPTION of Europe spec(DRL OP-
TION LINE = GND).
2)
It shall be able to operate only in case of B AUTO
LIGHT is active, and comply with CALIBRAION
PARAMETER TABLE of each spec.
3)
In GN1 SW ON state, if the supply voltage of the
AUTO LIGHT SENSOR is less than 4v or more
than 6v, it is determined as the fault. In the fault
state, in case of the AUTO LIGHT SW is ON, al-
ways HEAD LAMP RELAY shall be ON regard-
less of the Sensor value. FILTERING TIME for
the fault and recovery with regard to the supply
voltage is 300 msec respectively.
4)
In the condition of LIGHT ON, when the AUTO
LIGHT SENSOR value is entered into AUTO
LIGHT control condition, then LIGHT shall be
ON immediately.
5)
If IGN1 SW is ON, and AUTO LIGHT SW is ON,
and in LIGHT OFF state, and in case of AUTO
LIGHT SENSOR value is the input value of the
LIGHT ON, LIGHT shall be ON after 2.5 ± 0.2sec.
