Windshield wiper and washer switch function
The wiper system operates the wiper and washer using the signals from the multi-function switch, and
receives rain sensing signal from the rain sensor unit.
4. WIPER CONTROL
1. MIST
When the wiper switch is pulled up and
released, the wiper cycles once and then
returns to the park position. -
2. OFF
Stops the windshield wiper operation. -
3. AUTO
When the wiper switch is set to the AUTO
position, the wiper speed is adjusted
automatically according to the amount of
rain measured by the rain sensor mounted
on the windshield. -
4. LO/HI
When the wiper switch is set to the LO
position, the wiper speed is decreased.
When the switch is set to the HI position, the
wiper speed is increased. -
5. Wiper speed control switch
The wiper speed can be adjusted with this
switch as follows when the wiper switch is in
AUTO position.
* FAST: increases wiper speed
* SLOW: decreases wiper speed -6. AUTO washer switch
When the AUTO washer switch is pressed, the
washer fluid is sprayed once and the wiper is
operate 4 times. Then, the fluid is sprayed once
again with 3 wiping operations. -
7.
When the switch is fully turned, washer fluid will
be sprayed onto the rear window glass and the
wiper will also operate. When the switch is
and turn off the wiper and washer. -

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.

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,

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)

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. -

Seat belt reminder operation
A
BIf the seat belt is fastened after the seat belt reminder is activated, the output of the reminder is
turned OFF immediately. The reminder will be operated again whenever the seat belt is
unbuckled.
CWhen the seat belt reminder is activated initially with the seat belt unbuckled, the internal buzzer
(chime) is turned ON for 0.02 seconds and then turned OFF for 1.18 seconds (this cycle
continues for 5 minutes) and the driver seat belt warning lamp on the instrument cluster remains
on.
DWhen the seat belt reminder is activated with the seat belt unbuckled, the internal buzzer (chime)
is turned ON for 0.02 seconds and then turned OFF for 1.18 seconds (this cycle continues for 5
minutes) and the passenger seat belt warning lamp on the instrument cluster remains on, after
detecting that the passenger seat is occupied through the input value of the passenger seat
occupancy sensor.
EWhen the vehicle speed is changed while the seat belt reminder is turned on, the internal buzzer
(chime) is operated as follows:
FPriority of internal buzzer (chime) operation
(Seat belt reminder > ignition key reminder > sunroof warning > tail lamp warning > hazard
warning flasher on > turn signal indicator)GEN
The seat belt reminder is operated when the
vehicle is driven at 25 km/h or more with IGN
ON and alternator in High status (engine
running), and driver seat belt is not fastened. If
the vehicle speed is decreased to less than 25
km/h within 5 minutes after the seat belt
reminder is activated, the internal buzzer
(chime) is turned off. If the vehicle speed is
increased to 25 km/h or more, the buzzer
signal is output for 5 minutes. Only EU If the driver and passenger seat belts are not
fastened with the ignition switch ON, engine
running, vehicle speed above 10 km/h and
any passenger occupied, the seat belt
reminder is activated. In addition, even though
the vehicle speed reduces to below 10 km/h
after the reminder is activated at speed of 10
km/h or higher, it will remain activated.
