SsangYong Actyon Sports II. Service manual - part 83

If the wiper does not operate at high speed even in heavy rain, check the pins 1 and 2.

In other words, the wiper should operate at high speed when grounding the pins 1 and 2.

Symptom 5. The wiper does not operate at high speed even in heavy rain.

Symptom 6. The wiper responses are too fast or slow.

Check whether the variable resistance knob on the multifunction wiper switch is set in "FAST" 

or "SLOW".

Notify that the customer can select the sensitivity by selecting the variable resistance value. 

And, select a proper stage.

▶Auto Light Control

The tail lamps and headlamps can be controlled by the communication with the rain sensor only 

when the auto light switch is in "AUTO" position with the ignition switch "ON".

-

Rain detected headlamp: If it rains heavy which requires the highest INT speed (almost LOW), 

the headlamps are turned on automatically.

-

Night detected wiping: When the auto light control turns on the headlamps and the rain sensor 
detects the rain, the wiper sensitivity is automatically increased by one level in comparison with 

daytime.

(i.e. the AUTO wiper switch is at the 3rd level, but the wiper operates at the 4th level.)

-

Enlarged auto light sensor

Emitter lens
The LED emitting the infrared 

rays is installed on the bottom 

and the lens guides the infrared 

rays to target point.

▶Volume Sensitive INT (Intermittent) Wiper

For RKSTICS without the rain sensor, perform the following operation:

Controls the wiper intermittent operation by the values from the vehicle speed and the volume 

(resistance).

-

Calculates and converts the Intermittent interval automatically by obtaining the INT VOLUME 

when the ignition switch and the INT switch is in the "ON" position.

The wipers are operated in vehicle speed sensitive mode when turning the INT switch to the 

"ON" position with the engine running or starting the engine with the INT switch positioned to 

"ON".

Intermittent interval (at 0 km/h): 3 ± 

0.5 ~ 19 ± 2 seconds

Vehicle speed calculation

-

[Input the vehicle speed]

It is calculated by the numbers of input pulses for one second.

VOLUME calculation

-

The pause time of the vehicle speed sensitive INT wiper is calculated by the INT volume (input 
voltage). Each level has the hysteresis.

˙

Pause time calculation

-

Pause time means the duration that wipers are stopped at parking position.

Elapsed time means the duration after the wiper motor started to operate from parking 

position.

The pause time is calculated by the vehicle speed and the VOLUME.
※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.

Cautions for wiper control

1. Speed sensitive INT (intermittent) wiper

The wiper relay continues to output for remaining "ON" time even when the INT switch is 

turned off during its operation.

IGN switch "ON", INT switch "OFF": Resume the intermittent time when turning "ON"

IGN switch "OFF", INT switch "ON": Resume the intermittent time when turning "ON"

1)

2)

3)

2. Controls when the wiper motor parking is defective

The wiper relay continues to output when the parking terminal is fixed at the ground or IGN 

while the wiper relay is "ON" (INT switch = ON or washer switch = ON)

(The output stops immediately after turning off the switch)
