Operating process
- The ignition is turned OFF.
19. SLEEP MODE
If the state of the LOCK switches of driver/passenger/rear doors and tailgate is not changed for 6
seconds with the all doors including tailgate closed and IGN OFF (ignition key removed), even if the
state is not LOCK, the system enters the sleep mode to power down. 1.

closed for continuous 30 seconds after the door UNLOCK under the conditions stated in (1), the
system waits in normal mode. If the lamps or power window is deactivated and no change is
detected for 6 seconds after all doors are closed, the system enters the sleep mode. 3.
When the front room lamp is ON, the system turns of the room lamp in 10 minutes and enters the
sleep mode after 6 seconds. 4.
If the coming home light is ON, the system enters the sleep mode when the coming home light
switching off conditions are met. 5.
The sleep mode is deactivated when a door is opened or key is inserted. 6.

3) Immobilizer Ignition Key Verification
When turning the ignition key to the ON position, the power is supplied to the immobilizer unit and EMS
(ECU). The ECU communicates with the immobilizer unit to verify the key and transponder. If it is valid,
the ECU starts to control the engine or immobilizer indicator (illumination or flashing) when the ignition key
is turned to the START position.
Once the key is verified, valid key verification time is provided for 10 seconds and the engine can be
started by turning the ignition key to the engine START position during this verification time. If the ignition
key is turned to the START position again after the 10 seconds of verification time, the key verification
should be reperformed.
When the ignition key is inserted, the immobilizer unit requests the transponder verification through
the antenna.
The transponder sends the encrypted message to the immobilizer control unit.
The immobilizer unit compares the encrypted message received from the transponder to the
coded value through the logic circuit. If they are identical, it requests the transponder approval.
When the ignition is turned ON, the EMS (ECU) requests immobilizer verification process through
the P-CAN.
The immobilizer control unit sends the encrypted message to the EMS (ECU).
The EMS controls the engine normally when the coded value and the encrypted message sent
from the immobilizer are identical. 1.

When the immobilizer verification has failed, the verification signal is sent again 3 times for 2
seconds, and the verification procedure is carried out up to 3 times by turning the ignition ON within
10 seconds. If the three re-verifications fail, verification procedure is stopped and will be restarted
after 10 seconds.

When deleting the old code of the transponder registering an extra ignition key, please attend on
the site and observe the process personally.
In any cases, the immobilizer system cannot be removed from the vehicle. If you attempt to remove
it and damage the system, starting will be impossible. So never attempt to remove, damage or
modify it.
The remote engine starter cannot be installed to the vehicle equipped with the immobilizer system.
Do not drop the key or subject it to impact the key, as it may damage the transponder inside the
key.
The engine cannot be started using a key with damaged transponder.
In the following cases, you may experience starting problem or a system error can occur. 1.

5) Cautions for immobilizer
When two or more ignition keys come into contact with (each) other(s), or the key is close to any
device that sends/receives electromagnetic fields or waves.
When the ignition key is close to any electromagnetic device, such as lighting equipment, security
keys or security cards.
When the key is close to a magnetic, metal object, or battery. -

(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) -

6.
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.

3.
4.
5.
6.
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.)
