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.

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.

1. OVERVIEW
The SKM (Smart Key Module) system is equipped to only the vehicles with smart key and is to prevent
theft and enhance the driver experience. When the driver presses a door handle switch carrying a smart
key, this system checks the smart key information and driver door status and locks/unlocks the doors
(passive function). The vehicle can be started when the driver enters the vehicle and presses the
START/STOP switch (passive start function).

(3) Passive LOCK
The passive LOCK (door LOCK) is activated by the door handle switch with a valid smart key present
within the passive entry actuation area.
Passive LOCK and verification by door handle switch
The ignition is turned OFF or ACC is turned ON.
All doors are closed and the driver door is unlocked.
The door handle switch on the driver or passenger door is pressed briefly.
The SKM verifies if a smart key is outside the vehicle using the door handle antenna (LF verification)
(The SKM searches the last smart key used first. Searching for a smart key signal from the outside
the vehicle is followed by searching from the inside the vehicle).
The verification signal (RF verification) from the smart key is sent to the REKES antenna of the SKM.
The SKM sends the Passive LOCK signal to the BCM through the B-CAN if the verified smart key is
found outside the vehicle.
The BCM receives the signal from the SKM and controls the door LOCK actuator and turn signal
lamp. (The buzzer sounds once and hazard warning lamp flashes twice when the system enters the
theft deterrent mode) -

If no smart key is identified as being outside the vehicle, the passive LOCK process is stopped and
restarted when the next signal is received from the door handle switch.
When the door handle switch is pressed with ACC ON and driver door unlocked, the SKM changes
the ignition status to OFF and sends the passive LOCK signal to the BCM through the B-CAN to lock
the door. The BCM ignores the signal if the ignition is turned ON. -
-

(4) Passive UNLOCK
The passive UNLOCK (door UNLOCK) is activated by the door handle switch with a valid smart key
present within the passive entry actuation area.
Passive UNLOCK and verification by door handle switch
The driver door is locked and the system in the theft deterrent mode.
The door handle switch on the driver or passenger door is pressed briefly.
The SKM verifies if a smart key is outside the vehicle using the door handle antenna (LF verification)
(The SKM searches the last smart key used first).
The verification signal (RF verification) from the smart key is sent to the REKES antenna of the SKM.
The SKM sends the Passive UNLOCK signal to the BCM through the B-CAN if the verified smart key
is found outside the vehicle.
The BCM receives the signal from the SKM and controls the door UNLOCK actuator and turn signal
lamp. (The buzzer sounds twice and hazard warning lamp flashes once when the theft deterrent
mode is deactivated) 1.

If no smart key is identified as being outside the vehicle, the passive UNLOCK process is stopped
and restarted when the next signal is received from the door handle switch.
When the driver door is locked with ACC ON, the SKM sends the Passive UNLOCK signal to the
BCM through the B-CAN to unlock the door without changing the ignition status to OFF. (The vehicle
power is turned OFF when the door is opened.)
Smart key searching
* Theft deterrent mode: deactivated after searching the outside vehicle
* Theft deterrent mode deactivated: outside searching after inside searching -

(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.) -
