(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.)

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.

Smart key deactivation
This function prevents the operation by the smart key inside the vehicle even if the driver breaks in the
vehicle in the theft deterrent mode.
Deactivation conditions
- All doors closed (B-CAN)
- Theft deterrent mode activated (B-CAN)
- Smart key searchFOB deactivation: The smart key inside the
vehicle is deactivated when the passive
LOCK/REKES LOCK signal is input by a smart
key from the outside.
Smart key deactivation -
The REKES LOCK/passive LOCK (theft deterrent mode activation) request signal is sent by a
smart key outside the vehicle.
The smart key activated door LOCK is not found in the vehicle.
The system memorizes all smart keys found inside the vehicle as deactivated ones. 1.

Cancellation of smart key deactivation -
When the theft deterrent mode is deactivated using a smart key outside the vehicle, the
deactivated smart key functions returns to be available. 1.In theft deterrent mode, the smart key(s) inside the vehicle is deactivated to prevent theft.

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.

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). -

No engine operation
When the START/STOP button is pressed at the vehicle speed of 3 km/h or less, the SKM turns off
the IGN relay to stop the engine.
When the vehicle speed is 3 km/h or more or no speed signal is input, the SKM performs the
following functions: 1.
2.
Vehicle status Conditions
3 km/h or faster - When the START/STOP switch is pressed for 3 seconds
or more, 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.
Abnormal vehicle speed
(No or abnormal CAN signal)- When the START/STOP switch is pressed for 3 seconds
or more, 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 Power OFF.
(DTC set)
When the START/STOP button is pressed and held with IGN ON, the ignition status is changed to
OFF. When the START/STOP button is pressed briefly, the ignition status is changed to ACC ON. 3.
ACC ON to Power OFF
The SKM changes the ignition status to OFF from ACC ON when:
the engine START/STOP button is pressed with the brake pedal released after the ignition status is
changed from IGN ON to ACC ON.
the REKES LOCK or passive LOCK signal is input with ACC ON.

9. ESCL CONTROL
ESCL lock/unlock is not performed at ESCL virgin mode.
The SKM does not carry out the ESCL LOCK control if the engine is running with IGN ON or the
vehicle speed is 3 km/h or higher.
All the ESCL functions including START/STOP switch is disabled during anti-scanning flag bit set. -

-
If the smart key is pressed with power off, the electric steering motor performs the steering column
unlock. In some cases, power transition is carried out to ACC or IGN ON.
If the power transition and start is not possible after retry to LOCK or UNLOCK operation, the power
transition and start is not still possible after automatic retry and the warning lamp comes on. -

1) ESCL LOCK Control
When the ESCL is unlocked and the followings are met at normal condition:
If the driver door is open or closed with ignition key OFF, the electric steering motor performs the
steering column lock.

Smart key not detected warning deactivation conditions
- ACC OFF, IGN1 ON, Smart key detected
IGN ON and engine running
Smart key not detected warning deactivation conditions
- IGN1 OFF, Smart key detected, Door openAny door except the driver door is opened and then closed.
The SKM starts to identify a smart key by using the interior antenna after confirming that all the doors
are closed through CAN communication with the BCM.
When no smart key is found, the SKM sends the smart key not detected warning signal to the BCM
and instrument cluster through B-CAN.
The BCM activates the buzzer for up to 10 seconds at intervals of 0.5 sec. ON/0.5 sec. OFF and
turns on the smart key warning indicator on the instrument cluster.
If a smart key is found, no operation is performed. 1.
