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.

Operating process
- IGN ON

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

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
