Washer coupled wiper in rain sensing mode ▶
When the washer switch signal is received during intermittent operation coupled with rain sensor
with IGN ON and intermittent/automatic washer switch operation, the wipers operate in washer
coupled mode regardless of the communication with the rain sensor. 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.
Even though the wiping system is in washer coupled wiper mode, the operating data are sent to rain
sensor. 1.

Sensitivity adjustment (instant wiping) ▶
When the wiping speed control switch is turned to "FAST" with IGN2 ON, intermittent/automatic wiper
switch in "ON" position and wiper motor stop (parking position), the wiper motor operates one cycle at
low speed.
(only when the rain sensor detects raindrops)
If the wiping speed control switch is changed more than 2 stages within 2 seconds, the wiper motor
operates only one cycle. 1.

Wiper low/high control ▶
The wiper low relay is activated when the wiper low switch is operated and the wiper high relay
activated when the wiper high switch is operated.
The wiper motor returns to parking position and stops, even when turning off the ignition switch during
wiper operation.
The wiper relay should remain activated during wiper operation in low/high mode even though the
system does not receive P-POS signal. (During intermittent/automatic wiper operation, the wiper relay
should be deactivated after 5 seconds if there is no P-POS signal for 3 seconds in order to inform the
driver of faulty signal)
While the wiper operates at low/high speed, the front/rear washer switch can be operated but the auto
washer switch cannot.
The wiper motor returns to parking position and stops when turning off the ignition switch during wiper
operation in high mode. 1.

When briefly pressing (below 2.0 sec) the UNLOCK button on the transmitter, the doors are
unlocked.
The door unlock relay is turned ON for 0.5 seconds when receiving the door unlock message from
the transmitter.
The turn signal lamps blink only when all doors are successfully unlocked.
The REKES operation is not available when the ignition key is in the key switch. Also, it is not
possible to use the switches on the remote control key for 1 second after removing the ignition key
from the ignition switch to avoid unintended operation. 1.

power OFF, ACC ON or IGN ON. However, it is turned ON when the vehicle speed is below 3
(±0.1) km/h, with IGN ON.
The tailgate open relay is turned OFF immediately after the driver door is locked or the vehicle speed
goes over 3 km/h with IGN ON during its operation. However, the BCM does not operate if the
tailgate open switch is pressed when the vehicle speed is above 3 km/h. 1.

Tailgate control in BCM with SKM ▶
When pressing the tailgate switch for more than 0.1 second with driver door unlocked and vehicle
<009a0097008c008c008b00470089008c00930096009e0047005a0047004f00b700570055005800500047009200940056008f00530047009b008f008c0047009b008800900093008e0088009b008c004700960097008c009500470099008c0093008800a000
470090009a0047009b009c00990095008c008b004700760075> for about 1 second.
The tailgate open relay is turned OFF immediately after the driver door is locked or the vehicle speed
goes over 3 km/h during its operation.
When the tailgate switch on smart key is pressed in theft deterrent mode or with the smart key
detected by the exterior antenna, the SKM verifies the smart key and disarms the tailgate only. When
the tailgate is open and closed, the system enters into the theft deterrent mode again. If the tailgate
switch is not operated for 30 seconds, the system also does so.
The BCM checks that the verified smart key is in the luggage room 1 second after when the closed
tailgate is detected by the tailgate open switch with power OFF.
If there is a verified smart key in the luggage room when the tailgate is open and closed in theft
deterrent mode, the external buzzer sounds for 5 seconds.
When the driver press the tailgate open switch in order to look for the smart key, the BCM deactivates
lock so that the tailgate can be opened even though the driver door is locked. (maintains standby for
opening without verification) 1.

16) Time Lag Power Window Control
When turning the ignition switch to ON position, the power window relay is turned ON.
The power window relay keeps ON for 30 seconds even when stopping the engine.
However, the power window relay is turned OFF when opening a front door.
When locking the door (activation of theft deterrent mode), the power window relay is
immediately turned OFF. 1.

17) Sleep Mode
If the driver door/passenger door/rear doors/tailgate lock switch is not changed for 6 seconds with all
driver door/passenger door/rear doors/tailgate closed, key removed, IGN1 and IGN2 OFF, the
vehicle enters into sleep mode for system power down.
If any of conditions in Step (1) is not satisfied, the System Wake-up mode is activated.
When output such as room lamp, key hole illumination, tail lamps and power window is activating or
all the doors keep closed for 30 seconds after door is unlocked for conditions in Step (1), the system
is in normal mode. Then, if there is no change within 6 seconds with all output conditions and ready
conditions released and all the doors closed, the sleep mode is activated.
When turning on the overhead room lamp switch, the overhead room lamps come on for 10 minutes
and go off, and the sleep mode is activated after 6 seconds.
When the coming home light OFF conditions are satisfied, the sleep mode is activated.
In this condition, when opening a door or inserting the ignition key into key hole, the sleep mode is
deactivated. 1.

(2) Ignition status change
The ignition status is changed to OFF, ACC ON, IGN ON and engine cranking by one START/STOP
button.
The SKM cuts the power for IGN2 and ACC relays while the engine is cranking as cutting the electric
load is necessary.
The SKM monitors the brake pedal status through the hardware signals.
The ignition status change is available when the engine START/STOP button is pressed.
The SKM uses the EMS (engine condition) and ABS/ESP (FR vehicle speed) signals sent through the
P-CAN bus (High Speed CAN).
When the smart key battery is discharged and the driver inserts the smart key into the immobilizer slot
in emergency mode, the smart key verification is performed if the brake or START switch is pressed
before the ignition status is changed (ACC ON, IGN ON).

When the engine START/STOP switch is pressed for 3 sec. or more at more than 3 km/h, the
ignition status is changed from IGN to ACC.
If the engine START/STOP switch is pressed again, the ignition status is changed from ACC to
IGN.
The 4 vehicle speeds are abnormal (CAN signal timeout, abnormal signal):
If the engine START/STOP switch is pressed for 3 sec., the ignition status is changed from IGN
to ACC. If the switch is pressed again, the ignition status is changed from ACC to OFF (DTC
set). -

When the ignition status is changed, the SKM communicates according to the body network
conditions as follows: 9.

(3) Engine start
When the START button is pressed with the brake pedal applied and gear selector lever in P or N
position, the SKM performs the immobilizer verification and sends the engine START request signal
to the EMS if a normal coded smart key is found.
When the .engine start request signal from the START switch is received, the SKM sends the start
request signal through the PCAN and the smart key location signal through the BCAN to crank the
engine.
The SKM cuts the power for IGN2 and ACC relays while the engine is cranking as cutting the electric
load is necessary.
The SKM receives the engine start status signal from the EMS through the PCAN.
The SKM turns on the ACC/IGN2 relays after the engine cranking and sends the signal for [IGN after
starting] through BCAN.
When the START button is pressed and engine cranking request1 signal is sent, the EMS cranks the
engine after checking the engine warming up. If the engine cranking request2 signal is sent, the EMS
cranks the engine without checking the engine warming up. 1.

Engine cranking request2:
When the START switch is pressed once again while the engine cranking request1 signal is sent,
OR When the START switch is pressed for 3 sec. or more -
-
Starting engine while driving 7.
The engine start request signal is sent when the START switch is pressed, provided that the
vehicle speed is less than 10 Km/h or no vehicle speed signal is input, the gear selector lever is in
N position and the brake switch is ON with IGN ON (30 sec. verification is not required).
The engine start request signal is sent regardless of the brake signal when the START switch is
pressed, provided that the vehicle speed is 10 Km/h or more and the gear selector lever is in N
position with IGN ON (30 sec. verification is not required). -
