8710-01
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.

Operating process
- Intermittent operation with IGN ON and wiper AUTO switch in ON position

8710-01
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.

Operating process
- IGN ON/Wiper AUTO switch ON/Wiper motor in parking position

8710-01
Abnormal wiper parking signal stop (GND)
The wiper system sends the corresponding signal of current status with IGN ON and wiper AUTO
switch ON. (The wiper motor is operated only when the request signal from the rain sensor is
received.) A. Operation 1. (When the wiper motor parking signal stopped at GND)
Abnormal wiper parking signal stop (IGN)
The wiper system sends the corresponding signal of current status for 2 seconds (T2) with IGN ON
and wiper AUTO switch ON.
After the 2 seconds (T2), the system outputs the signal of the stopped status.
(The wiper motor is operated only when the request signal from the rain sensor is received.) A.
B. Operation 1. (When the wiper motor parking signal stopped at ING)

Operating process
- IGN ON/Wiper AUTO switch ON/Wiper motor in parking position

8710-01
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

8710-01
Operating process
- IGN ON/Wiper AUTO switch ON

Speed sensitive AUTO wiper
The speed sensitive AUTO wiper is operated as follows for the vehicles without rain sensor or the
vehicles without rain sensor coupled wiper operation because of faulty rain sensor.

The wiper remains activated for the time remaining when the AUTO switch is turned OFF during the
speed sensitive wiper operation.
The intermittent operation is reactivated when the AUTO switch is turned ON with IGN ON.
The intermittent operation is reactivated when the AUTO switch is turned ON with IGN ON. -
