2. INSPECTION
1) Cautions During Driving
The following lists cautions to take during test drive and on the turbocharger vehicle, which must
be considered during the operation.
It's important not to drastically increase the engine rpm starting the engine. It could make
rotation at excessive speed even before the journal bearing is lubricated and when the
turbocharger rotates in poor oil supply condition, it could cause damage of bearing seizure
within few seconds.
If the engine is running radically after replacing the engine oil or oil filter brings poor oil supply
condition. To avoid this, it's necessary to start off after idling the engine for about 1 minute
allowing oil to circulate to the turbocharger after the replacement.
When the engine is stopped abruptly after driving at high speed, the turbocharger continues to
rotate in condition where the oil pressure is at '0'. In such condition, an oil film between the
journal bearing and the housing shaft journal section gets broken and this causes abrasion of
the journal bearing due to the rapid contact. The repeat of such condition significantly reduces
life of the turbocharger. Therefore, the engine should be stopped possibly in the idle condition. 1.
2.
3.
After string for long period of time during winter season or in the low temperature condition
where the fluidity of engine oil declines, the engine, before being started, should be cranked to
circulate oil and must drive after checking the oil pressure is in normal condition by idling the
engine for few minutes.

Check whether the multifunction wiper switch is in the "AUTO" position.
Check the power to the sensor. Check the conditions of the pin 3 (Ground) and the pin
4 (IGN).
Check the wiper relay for defective. 1)
2)
3) Symptom 2. It rains but the system does not work in "AUTO" position. TROUBLE SHOOTING ▶
The wiper does not operate one cycle when turning the multifunctio
n
wiper switch to the "AUTO" from the "OFF" position or starting the engine
while the wiper switch is in the "AUTO" position.
When starting the engine with the multifunction wiper switch in the "AUTO" position,
the wiper operates one cycle to remind a driver that the wiper switch is in the "AUTO"
position.
When the multifunction wiper 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. 8 pin. If the pin is normal,
check the wiper relay related terminals. 1)
2)
Symptom 3. The wiper operates 3 or 4 times at high speed abruptly.
Check whether the variable resistance knob on the multifunction wiper switch is set in
"FAST". The "FAST" is the highest stage of sensitivity and very sensitive to small amount
of rain drops. Therefore, change the knob to low sensitivity.
Symptom 4. The wiper operates continuoulsy even on the dry windshield glass.
Check the wiper blade for wear. If the wiper blade cannot wipe the glass uniformly
and clearly, this problem could be occurred. In this case, replace the wiper blade
with new one.
Check whether the variable resistance knob on the multifunction wiper switch is set
in "FAST" The "FAST" is the highest stage of sensitivity and very sensitive to small
amount of rain drops. Therefore, change the knob to low sensitivity. 1)
2) Symptom 1.

▶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 IN
T
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. ˙
