AUTO washer switch coupled wiper operation
The wiper AUTO switch is in the OFF position with IGN ON
When the AUTO washer switch is turned ON for 0.1 seconds or more (T1), the windshield washer
motor is activated for 2 seconds (T2).
The windshield wiper LO relay is operated 4 times (T5) 0.5 seconds (T4) after the windshield washer
motor has been activated.
And then the windshield wiper LO relay is deactivated 3 times (T6) of operation while the windshield
washer motor is activated for 1.5 seconds (T3). A.
B.
C.
D. Operation 1.
The input from the AUTO washer switch during the washer coupled wiper operation is overridden.
The input from the AUTO washer switch during the AUTO washer coupled wiper operation is
ignored.
The input from the AUTO washer switch during the speed sensitive intermittent wiper operation is
ignored.
When the signal from the intermittent wiper switch is received during the AUTO washer operation,
the AUTO washer doesn't operate any longer and the intermittent wiper operation will be performed.
The input from the washer switch during the AUTO washer operation is ignored. -

Operating process
BCM and rain sensor system diagram
Data recognition time
The LIN communication is established when the ignition is turned ON, regardless of the wiper and light
switch operation. Then the function for the LIN data is carried out with the wiper AUTO switch or AUTO
light switch in the AUTO position.
The data from the rain sensor is recognized as 2 consecutive data.
Operation when data is recognized
Data OFF: Lo/HI relay output OFF
Low speed signal: LO relay output ON (ON for at least 1 revolution), HI relay output OFF
High speed signal: HI relay output ON (ON for at least 1 revolution), LO relay output ON
The washer input is overridden during continuous operation of wiper. (washer coupled wiper operation
during intermittent operation)

Power-up reminder wiper
The wiper AUTO switch is in the ON position.
The ignition is turned ON, and then OFF, and then ON again.
The windshield wiper LO relay is not operated. A.
B.
C. Operation 1.
The position of the wiper AUTO switch is changed to the ON from the OFF position with IGN ON.
The wiper motor rotates once (T1) initially when the windshield wiper LO relay is activated, regardless of
the rain sensor communication. D.
E. Operation 2.
The ignition is turned ON with the wiper AUTO switch in the ON position.
The windshield wiper LO relay is not operated. F.
G. Operation 3.
(The rain sensor did not detect rain drops after Operation 2.)
Operation 4.
(The rain sensor detects rain drops after Operation 2.)
The ignition is turned ON with the wiper AUTO switch in the ON position.
The windshield wiper LO relay is operated. H.

Washer switch input during rain sensor coupled operation
The windshield washer switch is in the ON position.
The communication with the rain sensor is ignored. (can misread washer fluid as rain drops)
The washer coupled wiper operation is activated (T1).
After that, the wiper is operated by rain sensor coupled operation (T2).
However, if the washer switch signal is received the washer relay is activated and wiper relay remains
activated, when the data coupled with rain sensor indicates continuous wiper operation. A.
B.
C.
D. Operation 1.
- The rain sensor coupled data is not continuous wiper operation.
Basic conditionsIntermittent operation with IGN ON and wiper AUTO switch in ON position
Even though the wiping system is in washer coupled wiper mode, the operating data are sent to rain
sensor from the BCM.

Wiper speed control
The amount of rain is detected by the rain sensor.
The windshield wiper LO relay is operated once (T1).
The amount of rain is not detected by the rain sensor.
The windshield wiper LO relay is not operated. A.
B. Operation 1.
Basic conditionsIGN ON/Wiper AUTO switch ON/Wiper motor in parking position
If the speed level is changed more than 1 stage within 2 seconds, the windshield wiper motor runs
only one cycle.

Rain sensor malfunction (rain sensor external malfunction)
The wiper LO relay is operated once (T1). A.
B. Operation 1.
("rain sensor installed improperly" signal received from the rain sensor)
Basic conditionsIGN ON and wiper AUTO switch in ON position

Rain sensor malfunction (no rain sensor signal)
The wiper LO relay is operated once (T1). A.
B. Operation 1.
("no signal detected" signal received from the rain sensor)
Basic conditionsIGN ON and AUTO switch ON

Wiper troubleshooting
The wiper does not cycle one time when turning the multi-function wiper
switch from OFF to AUTO position or when starting the engine with the multi-
function wiper switch in AUTO position. Symptom 1.
When starting the engine with the multi-function wiper switch in AUTO position, the wiper always
cycles one time to remind the driver of system in AUTO mode.
This wiper operation is performed only for the first time when turning the multi-function wiper switch
from OFF to AUTO position with IGN ON. If the switch is turned from OFF to AUTO again after
that, the wiper is operated only when raining to prevent the wiper blade from wearing. 1.
2.
It rains but the wiper does not work with the wiper switch in AUTO position. Symptom 2.
Check if the multi-function wiper switch is in AUTO position.
Check the power to the rain sensor. That is, check the pin no. 3 (GND) and pin no. 4 (IGN).
Check that the wiper relay is intact. 1.
2.
3.
The wiper operates 3 or 4 times with high speed abruptly. Symptom 3.
Check if the wiper speed control switch is set to the fast side.
The fast stage has the highest sensitivity and is very sensitive to the small change of amount of rain
drops. Therefore, adjust the knob to lower the sensitivity level.
The wiper continues work even if the windshield glass is dry. Symptom 4.
Check the wiper blade for wear. If the wiper blade cannot wipe the glass uniformly and clearly, this
problem could occur. In this case, replace the wiper blade with a new one.
Check if the wiper speed control switch is set to the fast side. 1.
2.
The fast stage has the highest sensitivity and is very sensitive to the small change of amount of rain
drops. Therefore, adjust the knob to lower the sensitivity level.
The overall wiper response is too fast or slow. Symptom 5.
Check if the wiper speed control switch is set to the fast or slow side.
Notify that the user can select the sensitivity by selecting the variable resistance value. And, select a
proper stage.The wiper also cycles one time when the multi-function wiper switch is turned from OFF to AUTO
position during 5 minutes after the rain stops.

Wiper LO/HI control
When front or rear washer signal is input during the wiper LO/HI operation, the front or rear washer
motor is activated.
The AUTO washer input is overridden during wiper LO/HI operation. A.
B. Operation 1.
When the signal from the wiper LO/HI switch is received, the wiper LO/HI relay is turned ON/OFF.
(The wiper LO relay is always activated when the HI relay is activated.)
If the ignition turned OFF while the wiper is operated, the wiper stops operating when the wiper
motor parking signal is input.
If no wiper motor parking signal is input during the wiper LO/HI operation, the wiper relay continues
working. (If no wiper parking signal is input for 3 seconds of wiper AUTO operation, wiper relay is
deactivated after 5 seconds - failure notification)
When the ignition is turned OFF during the wiper HI operation, the wiper is operated in LO mod and
then returns to the parking position. -
