Operating process

Emergency hazard warning lamp control (coupled with ABS)
The emergency stop signal is input from the ABS/ESP module with the vehicle driven at 50 km/h or
more.
The hazard warning lamp flashes at 4 Hz (T1) and internal buzzer (chime) sounds at 1.25 Hz. A.
B. Operation 1. (emergency stop signal)
During operation 1 (emergency stop signal activated)
The vehicle speed decreased to 50 km/h or less
The hazard warning lamp flashes for 10 seconds (T2) at 1.25 Hz and then goes out. C.
D.
E.
The BCM activates emergency hazard warning lamp operation when receiving emergency braking
signal from the ESP/ABS.
Priority of operation
(Manual operation of hazard warning lamp > Emergency stop signal > Emergency AUTO hazard
warning lamp > AUTO hazard warning lamp) -
lamp)
During operation 2 (emergency AUTO hazard warning lamp)
The hazard warning lamp switch is turned OFF.
The hazard warning lamp is turned OFF because the manual operation overrides the emergency
AUTO operation. F.
G.
H.
The emergency stop signal and emergency AUTO hazard warning lamp signal are switched off
when the vehicle speed exceeds 10 km/h (if emergency stop signal is input).

Operating process
The BCM activates emergency hazard warning lamp operation when receiving emergency braking
flasher ON signal from the ESP/ABS.
When the emergency stop signal is input through the P-CAN, the hazard warning lamp flashes with the
frequency of 4 Hz and the internal buzzer sounds at 1.25 Hz.
P-CAN signal during operation: Emergency Stop=EBL_INFO=0*0=Hazard Warning Lamp unrequested

Passive entry function actuation area: Within 1.2 m from the door handle antenna
Passive tailgate open actuation area: Within 1.2 m from the center of the bumper -
-
(1) Passive entry actuation area
Searching for a smart key signal from the outside the vehicle is prioritized in the theft deterrent mode
when the passive entry signal is input. Searching for a smart key signal from the inside is prioritized
when the theft deterrent mode is deactivated.
The system searches a smart key only in the actuation area of a switch, which the signal is input
(driver/passenger door handle switches and tailgate open switch). -
-
4. PASSIVE ENTRY MANAGEMENT
1) Passive Function
The passive entry actuation area refers to the area where passive LOCK/UNLOCK can be
performed by pressing the switch on the driver or passenger door handle with a smart key carried by
the driver.
The passive tailgate open actuation area refers to the area where the tailgate can be opened by
pressing the tailgate switch with a smart key carried by the driver. -
-
LF transmission: Verification request signal
RF transmission: Response signal

(5) Passive tailgate open
The tailgate open control is activated by the tailgate open switch with a valid smart key present within the
passive entry actuation area.
Passive tailgate open by tailgate open switch
When the tailgate is closed with all doors closed, the system enters the theft deterrent mode after
checking a valid smart key inside the vehicle. When a valid smart key is found inside the vehicle, the
external buzzer and smart key detected warning indicator is operated for 10 seconds.
If no smart key is identified as being outside the vehicle, the passive gate open process is stopped
and restarted when the next signal is received from the tailgate open switch.
Smart key searching
* Theft deterrent mode: deactivated after searching the outside vehicle
* Theft deterrent mode deactivated: outside searching after inside searching -
-
-The driver door is locked and the system in the theft deterrent mode.
The tailgate open switch signal is received.
The BCM sends the valid smart key verification request signal to the SKM.
The SKM verifies if a smart key is outside the vehicle using the corresponding rear bumper antenna
(LF verification) (The SKM searches the last smart key used first. If a valid smart key searching is
completed, searching for a key in the luggage compartment and inside the vehicle is started).
The verification signal (RF verification) from the smart key is sent to the REKES antenna of the SKM.
The SKM sends the Passive tailgate open signal to the BCM through the B-CAN if the verified smart
key is found outside the vehicle.
The BCM activates the tailgate open relay according to the signal received from the SKM.
(Only the theft deterrent mode for tailgate is deactivated.) -

Engine starting
When the START/STOP 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/STOP switch is received, the SKM sends the
start request signal through the P-CAN and the vehicle power status signal to the BCM through the B-
CAN.
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 (ECU) through the P-CAN. 1.

EMS (ECU)Engine rpm, engine cranking/stop/running/loaded
TCUGear selector lever position: P, N
ABS/ESPVehicle speed signal (wheel speed sensor on each wheel)
The SKM turns on the ACC/IGN2 relays after the engine cranking and sends the signal for IGN after
starting to the BCM through the B-CAN.
When the START/STOP button is pressed and engine cranking request1 signal is sent, the EMS
(ECU) 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. 5.
6.
Engine cranking request1
(engine start after
warming up)When the START/STOP button is pressed briefly under the start
conditions, the vehicle starts to warming up and then the engine is started
after a certain amount of time (warming up indicator ON to OFF).
Engine cranking request2
(engine start without
warming up)When the START/STOP switch is pressed once again while the engine
cranking request1 signal is sent, the engine is started (regardless of
warming up indicator)
It can be delayed by several seconds according to the engine
coolant temperature.
Starting engine while driving 7.
The engine start request signal is sent when the START/STOP 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/STOP
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). -

(9) SKM error alert
The SKM sends the SKM error alert signal to the instrument cluster through the B-CAN for up to 10
sec. when an in ignition status related error or passive entry system error occurs.
SKM error transmission conditions
When any of the following errors is detected and a DTC is set, the SKM sends the error alert signal for
10 sec.
