1. CAUTIONS WHEN WORKING ON ELECTRICAL UNITS
Disconnect the negative cable from the battery
in advance when working on electrical units. -
If a fuse is blown, replace it with a fuse which
has the correct amperage rating. If you use a
fuse with higher capacity than the
specification, the component can be
damaged or catch fire. -Do not drop or appy excessive impact to
sensors and relays. -
10 A 15 A
Make sure to turn "OFF" the ignition switch
and other lamp switches before disconnecting
or connecting the negative battery cable.
(Otherwise, semiconductor parts can be
damaged.)

4. WITH SKM VS. WITHOUT SKM
BCM (BODY CONTROL MODULE)
BCM (Body Control Module) inputs/outputs data from various switches, sensors, and other modules
through the hard wire and CAN communication, and controls the body and electronic system of the
vehicle.
For the vehicles with SKM, the SKM unit communicates with BCM through B-CAN. It sends the door
LOCK/UNLOCK signal by smart key, theft deterrent mode signal, and passive entry signal, etc. to the
BCM to control each module. The signals for engine running and stopping controls are sent to the EMS
(ECU) through the P-CAN.
For the vehicles without SKM, the BCM receives door LOCK/UNLOCK signal by smart key, theft
deterrent mode signal, and passive entry signal, etc. directly from the modules to control them. The
BCM controls the engine running and stopping by sending the corresponding signals to the EMS (ECU)
after verifying the ignition key. The controls for other modules may vary depending on the vehicle
specifications.

1. OVERVIEW
BCM (Body Control Module) is a module that inputs/outputs data from various switches, sensors, and
other modules through the hard wire and CAN communication, and controls the body, electronic system,
and chassis of the vehicle.

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. -
8. OFF
Rear wiper is not in operation. -
9. Rear wiper operation (Intermittent) -
10. Rear wiper operation (Normal Speed) -

TYPE B
Rear wiper operation
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 released, it will return to the Rear
Wiper Operation mode and only the wiper will keep operating.9. INT

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 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.

G. Operation 3.
(The rain sensor did not detect rain drops after Operation 2.)
Operation 4.
