2013 SSANGYONG TURISMO wipers

02-78710-01
If the washer operating signal is inputted while the wipers are operating in intermittent or AUTO
mode, the system stores the previous intermittent interval and operates the washer coupled wiper.
After then, the wiper operation returns back to intermittent or AUTO mode with the stored operating
interval. 3.

(2) Rain Sensor Coupled Wiper
▶ System layout
This vehicle has a different wiper control logic compared to other models. As shown in the system
diagram, the rain sensor unit does not control wiper directly. The rain sensor unit sends infrared rays
signal through LED and then receives it with photo diode and then sends the returned signal to STICS
and the STICS controls the wipers directly.
For more details, refer to rain sensing wiper section in this manual.

▶ Speed Sensitive INT (Intermittent) Wiper
For STICS without rain sensor, perform the following operation:
1. Controls the wiper intermittent operation by the values from vehicle speed and volume.
Calculates and converts the Intermittent interval automatically by using the vehicle speed and INT
VOLUME when the ignition switch is in “ON” position and the INT switch is in “ON”
position (the engine is running).
The wipers are operated in vehicle speed sensitive mode when turning the INT switch to
“ON” position with the engine running or starting the engine with the INT switch positioned
“ON”.
Intermittent interval (at 0 km/h): 3 ± 0.5 ~ 19 ± 2 seconds -

2. Vehicle speed calculation
[Input the vehicle speed]
It is calculated by the numbers of input pulses for one second.
1 [pulses/sec] = 60 [km/h] x 60 [sec] / 637 pulses = 1.41 [km/h]
3. VOLUME calculation
Calculates the INT VOLUME with 5 grades as shown in the table in next page. -
4. Pause time calculation
Pause time: the duration that wipers are stopped at parking position
Elapsed time: the duration after the wiper motor started to operate from parking position
The pause time is calculated by the vehicle speed and VOLUME value as shown in the table in
next page. -
-
-
If the pause time is below 1.0 second, the wipers operate without pause.
If the pause time is over 1.5 seconds, the wipers operate intermittently. ·

2. CAUTIONS ON RAIN SENSOR
When the wiper switch is in the AUTO position, the wiper will operate for 1 cycle if the initial engine
start is made. This may cause the wiper blades to wear prematurely. Therefore, other than rainy
days, set the switch to the OFF position. Especially during the winter time, check if the wiper blades
are not frozen to the windshield.
Operating the wiper with the blades frozen can damage the wiper motor.
If you operate the wipers when the windshield is dry without spraying washer fluid, the windshield can
be scratched and the wiper blades can wear prematurely. Use the wiper with the washer fluid when
the windshield is dry.
When it does not rain, turn the wiper switch to the OFF position.
Turn the wiper switch to the OFF position before any car wash to avoid unwanted operation of the
wipers. -

-
-
When cleaning the windshield over the sensor with damp clothes, the wiper may operate suddenly.
It could cause serious injury. Make sure to place the wiper switch to the OFF position and ignition
switch OFF when not in use.
Irregular operation (abrupt operation) ▶
Check if the sensor is off the position.
Check if the rain sensor cover is securely installed.
Check if the customer is familiar to how to control the wiper sensitivity.
Check if the wiper sensitivity control is set to the FAST side (step 5).
Check the wiper blade for wear.
If the wiper blade cannot wipe the glass uniformly and clearly, it may cause the rain sensor to work
irregularly. Therefore, in this case, replace the wiper blade with a new one. -

2. RAIN SENSOR OPERATION
The rain sensor is installed on the specific heat treated windshield that has minimum 13% of
transmittance rate with specified intensity of radiation. It is installed on the glass with a adhesive of
Sorepa.
It communicates with STICS and makes the wipers to operate automatically under the rain sensing
mode (multifunction switch wiper: AUTO mode).
The emitting section of the rain sensor unit emits infrared rays against the windshield and then detects
the amount of rain drops by receiving reflected rays with photodiode.
The sensing section on the windshield is located just above the center point between LED and
photodiode.

4. FUNCTIONS OF RAIN SENSOR
1) Windshield Glass and Coupler Attachment
Check the outer windshield surface of sensing area for wear, damage and scratch. The sensor is able
to compensate the wear up to a specific level. Check the coupler attached surface of windshield for
porosity. If the porosity exists, the sensor cannot function properly.
2) Recognition of AUTO Mode
3) Instant Wipe Function
When the variable resistance knob on the multifunction wiper switch is turned by each 1 stage from
low sensitivity (S mark) to high sensitivity (F mark), the wiper operates one cycle.
And, the wiper also operates during raining up to 5 minutes after rain stops.When the engine is started with the wiper switch “AUTO” position, the wiper operates one
cycle to remind a driver that the wiper switch is in “AUTO” position.
When the wi
per switch is turned to “AUTO” from OFF, the wiper operates one cycle. It always
operates one cycle for the initial operation, however, the wiper does not operate afterwards to
prevent the wiper blade wear if not raining when turning the wiper switch to “AUTO” from
“OFF”. However, the wiper operates up to 5 minutes after rain stops.
If this function does not occur, check No. 2 terminal on the rain sensor. If any defective cannot be
found, check the wiper relay (LOW) for defective. 1.
2.
3.If the installed wiper brushes are out of specification (size and length), the rain sensing area
cannot be fully wiped. In this case, the rain sensor’s sensitivity could be decreased and
the wipers are not properly operated. - The followings are the detailed description of the functions and operations of the rain sensing wiper
control.
As described, the STICS recognizes the wiper switch “AUTO” position. If there are not any
problem, go to diagnosis mode in STICS and check the terminal that receives signal from wiper
and communication lines between rain sensor unit and STICS. -
When the variable resistance knob is rotated by 4 stage from 0 stage without stopping, the wiper
operates one cycle. The wiper operates one cycle when changing the wiping stage (0 →
1, 1 → 2, 2 → 3). -
