Theft deterrent mode deactivation conditions (for vehicles with SKM)
When UNLOCK signal by the smart key with IGN OFF or by the door handle switch with the door
locked is received, the door UNLOCK signal is output and the theft deterrent mode is deactivated
after the hazard warning lamp (once) and external buzzer (SKM buzzer) (twice) operations.
If UNLOCK signal by the smart key is received after the deactivation of theft deterrent mode, the
hazard warning lamp relay and external buzzer (SKM buzzer) are turned ON.
When the tailgate open signal by the smart key or tailgate open switch is received, only the theft
deterrent for tailgate is deactivated.
The theft deterrent mode is deactivated when the ignition is turned ON. -

(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.) -

5. REKES CONTROL FUNCTION
REKES LOCK operation
The REKES LOCK signal is sent when the LOCK button on the smart key is pressed briefly (0.1 sec.
to 1.5 sec.).
The SKM receives the REKES LOCK signal and sends the REKES LOCK request signal to the
BCM through B-CAN.
The BCM outputs the door LOCK signal according to the signal received from the SKM. 1.
2.
3.
When the REKES LOCK signal is received with the ACC ON, the ACC is turned OFF and the
REKES LOCK signal is sent.
REKES UNLOCK operation
The REKES UNLOCK signal is sent when the UNLOCK button on the smart key is pressed briefly
(0.1 sec. or more).
The SKM receives the REKES UNLOCK signal and sends the REKES UNLOCK request signal to
the BCM through B-CAN.
The BCM outputs the door UNLOCK signal according to the signal received from the SKM. 1.
2.
3.
Tailgate open operation
The ignition is turned OFF, ON, or ACC is turned ON.
The tailgate open signal is sent when the tailgate open button on the smart key is pressed 1 second
or more.
The SKM receives the tailgate open signal and sends the tailgate open request signal to the BCM
through B-CAN.
The BCM activates the tailgate open relay when the tailgate open switch is pressed. 1.

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.
2.
3.
4.
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). -
