1. OFF Mode

If switch of wiper is turned off and switch of ignition
is turned on, at this time, rain sensor is operating
with OFF MODE, under this mode, wiper mode is
stopped, during rain sensor is OFF MODE, rain
sensor is sensing the state of windshield, so that
turn switch to proper position.

2. Auto Mode

If wiper switch is transferred OFF MODE into AUTO
MODE, immediately wiper is operating once, that
means wiper system is operating, after wiper is
operating once, is calcurated the time of gap
between drop of rain and speed of wiper operation.
After stoppng time, rain sensor transfer signal into
wiper motor, wipe out rain.

3. Automatic Intermittent Mode

At the automatic intermittent mode, wiper is
operating once with low speed, and then this mode
has variable stopping time.

4. Automatic Low Speed

This mode is operating beyond value of limit of
automatic intermittent and automatic low speed.

5. Automatic High Speed

As quantity of rain beyond value of automatic low
speed and automatic high speed is operating.

6. Washer Mode (48Page)

Rain sensor is sensing whether switch of wiper
select function of washer or not. If switch of wiper
is turned on more than 0.6 sec, wiper is operating
for 2.5 - 3.8sec, under this value is operating only
once. At washer mode, motor of wiper is operating
with low speed.

7. Manual Mode

Switch operation of driver turn motor of wiper to low
speed, high speed, at this time, wiper is operated
by not rain sensor by but wiper switch.

Notice:  As rain sensor is out of order, wiper is
operating with low speed and high speed.

Characteristic of rain sensor

1.Supply power

Power is supplying to rain sensor and within 250
msec, rain sensor is emitting the signal “ OFF” ,  until
effective power is supplying, effective power is
available for supplying power, after 2 second.

2. Speed of wiper and control frequency of

revolution

Main function of rain sensor is controlling wiper
speed and delaying of time to between the driving
time, due to sensing and the accumulation of rain,
algorithm of rain sensor is deciding mode of motion,
automatic intermittent, automatic low speed, and
automatic high speed.

If the stage is set, without the operation of driver,
wiper is continuously operating.

3. Transfer between the modes

Algorithm of rain sensor is transferred automatic
intermittent,automatic low speed, and automatic
high speed under low stage so doesn’t make noise.

4. Performance of sensing

Sensing of rain sensor is set 5 stage, due to
accumulated drop of rain, driver can satisfy, range
of adjusting can control from the short delaying time
to thelong delaying time, but, due to heavy rain,
regardless of sensing which is set, is continuously
operating with high speed.

5. Responding characteristic of automatic low

speed

As wiper is operated from the zero state of
dropping of rain to the automatic low mode.

Time is needed within only 9 second for high
required signal.

6. Responding characteristic of automatic high

speed

As wiper is operated from the zero state of dropping
of rain to the automatic high mode.

Time is needed within only 9 second for high
required signal

7. Responding characteristic from the automatic

low speed to the automatic high speed

As wiper is operated from the automatic low speed
to the automatic high speed mode, time is needed
within only 6 second for high required signal.

8. Responding characteristic from the automatic

high speed to the state of off (48 Page)

As wiper is operated from the automatic high speed
mode to the the zero state of dropping of rain mode,
times of wiper motion is under 19 times.

9. The instant operating of wiper

While system of wiper is operating by switch of
wiper, before wiper back to the position of operating,
wiper is operating once, such as once operating, is
occurred at time from the lower stage to the high
stage by operating of wiper switch, but if the high
stage is moving to the low stage, once operating
of wiper does not happen.

If the ignition switch  is off and if wiper switch is
set on any position, turn ignition switch on, the
instant operation of wiper is occurred, signal to
driver beginning of wiper operating, due to lack of
rain drop, if wiper is not operated, rain sensor stay
on the automatic intermittent mode.

Check unit of rain sensor

Check selection of sensing (check position of nob
of variable resistent)

Check if variable resistent nob of multifunction switch
is positioned in the middle of between S of position
and F of position, if nob is positioned F (fast) or S
(slow),sensing is much higher or much lower, so
customer can complain this.

Self - diagnosis

1. Rain sensor has two kind of self diagnosis test

mode.

1) Self diagnosis of FAULT A

In case operating point of rain sensor servo is
beyond range of soft ware, that means sensor
has a fault, if part of wind shield glass has a
damage, or if sensor is removed from the
coupler.

2) Self diagnosis of FAULT B

While rain sensor does not reaction with signal
of rain, that means FAULT B, if wind shield glass
which is equipped coupler has a damage or
sensor is out of order.

2. Value of cohesion

While FAULT A is sensed, the cohesion is decided,
the value of cohesion is 140,in this case, except
heavily damage of wind shield glass, rain sensor
is operating in the all conditions.

3. Failure which is occurred with adjustment of

intermittent volume

Due to adjustment of sensing and motion of wiper,
self diagnosis is described as below.

1) Wiper switch is transferred the intermittent into

5 step stage, under the state of “  ignition on “

2) Under this state, sensing is changed 5 step

stage into 4 step stage.

3) At this time, wiper is moving once, that means

self diagnosis of FAULT A, check if wind shield
glass has a damage or not, also check if sensor
is installed completely on the coupler.

4) After check 3) article, sensing is changed 4 step

stage into 3 step stage.

5) If wiper is operating once, this means self

diagnosis of FAULT OF B.

Replace new rain sensor.

Wiper blade

Check the state of wear of wiper blade, due to
excessive wear of wiper blade, if is not cleaned up
over section of sensor, quantity of rain is not sensed
accurately.

Coupler

Check if blister is shaped on the external section of
coupler which is stuck on the wind shield.

If there is a blister in the internal section of sensor, is
not sensed accurately, check if coupler is installed
the right position or not, specially check if section of
coupler sensor is positioned on the section of ceramic
coating or not, if the space of sensing is shielded,
infrared of sensor is not passed so sensing is not
available accurately.

Wind shield glass

Check if wind shield glass surface of the external
sensor has excessive wear,damage, and scratch or
not. Wear of sensor is compensated little bit, if there
come to beyond constant value, sensor is not sensing,
such a kind of diagnosis is used self diagnosis.

Exterior cover

Check the state of exterior cover of rain sensor, check
that sensor is impacted by shaking, owing to releasing
fixing section of cover, also check interference with
wind shield glass or head lining.

Spring clip

Check if rain sensor release from coupler or not, after
removing exterior cover, check the state of spring clip.

Connector

After check the state of tighting between terminal of
connector and wiring, check that the terminal is inserted
into connector as the state of locking. Check the state
of combination  between the connector of wiring and
the connector of rain sensor, check interference between
them.

Relay

Check if low relay of wiper and high relay of wiper is
operating normally, as relay is damaged by fire so
motor of wiper is not operated, at the auto mode, blade
of wiper is not operated.

Circuit

Check circuit, specially check if the value of variable
resistence of multifunction switch is feeding properly
or not, this can see by moving nob of variable
resistence step by step from the state of slow to the
state of fast (This is called Instant Wipe ).

If parking position of wipe motor is not feeding properly
or not, if parking position of wipe motor is not feeding,
wiper motor can be operated quickly rather than the
state of normal, intermittent speed shifting time of wiper
motor is not sensing, wiper motor is not operated
normally.

Notice: While unit of rain sensor is removed.

1. Remove exterior cover, at this time, if exterior cover

is removed by compulsion, keep in mind not to
break fixing hook of coupler, as exterior cover is
removed,  using hole of cover by driver, after section
of fixing hook is pushing, and remove  them.

2. As rain sensor is removed from coupler, using

driver after open up spring clip, remove them.

3. Remove connector to the wiring from the sensor.
