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. -

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.

(4) Smart key battery discharge warning (3) Smart key verification fail warning
When the verification is requested for ignition status change or engine starting and no verified smart key
is in the vehicle, the SKM sends the "smart key verification status" signal, which indicates that the
verification has failed, for up to 10 sec. until the verification fail conditions are deactivated. for up to 10
seconds. until the verification fail conditions are deactivated.
Verification fail detection and transmission conditions
When the ignition status is changed after a smart key is verified by the START/STOP switch ON
input, the SKM sends the verification status for 10 sec. -Normally, the smart key verification warning is one of the smart key fail conditions. -
Ignition status change
(OFF -> ACC) / (OFF -> IGN)/(ACC -> IGN) / (IGN -> engine ON) *
If above conditions are met again, the SKM re-verifies a smart key and sends the verification status
for another 10 seconds.
When the ignition status is changed by the transponder verification while the smart key status is sent
through the B-CAN, the SKM sends the smart key verification signal and also sends the transponder
verification signal for 10 seconds. -
-
If low smart key battery is detected during the verification process for ignition status change or engine
start, the SKM sends the signal for "smart key battery low voltage warning" to the BCM and instrument
cluster through the B-CAN for up to 10 sec. until the warning condition is deactivated.
Smart key battery discharge confirmation and deactivation
If the smart key battery low voltage is confirmed, the SKM sends the smart key battery low voltage
warning signal.
If the smart key battery is in normal condition, the SKM sends the smart key battery low voltage
warning deactivation signal.
The smart key is the last used key. -
-
*
(5) Transponder verification fail warning
If a verified smart key is not found by the key verification process, the SKM sends the information that
indicates the key is not verified to the instrument cluster through the B-CAN for up to 10 seconds until
the warning condition is deactivated.
The SKM sends the transponder verification warning when the verification has failed with the smart
key inserted into the immobilizer holder. -
Transponder verification fail detection and transmission conditions
When the ignition status is changed after the transponder is verified by the START/STOP switch ON
input, the SKM sends the transponder verification status for 10 sec. -

Ignition status change*
If above conditions are met again, the SKM re-verifies the transponder and sends the verification
status for another 10 sec.
When the ignition status is changed by a smart key verification while the transponder verification is
processed, the SKM sends the signal for [transponder verification fail], and sends the smart key
verification status for 10 sec. -
-
(6) Transmission position warning
When the gear selector lever is in a position other than P or N with IGN ON and engine started, the
SKM sends the [gear position warning] signal to the instrument cluster through the BCAN for up to 10
sec. until the operating conditions are deactivated.
Transmission position warning deactivation
When re-attempting to start with IGN1 ON and transmission in P or N -
(7) ESCL JAM warning
The SKM transmits the warning active command to the BCAN through the BCAN signals such as ESCL
NOT LOCKED warning signal or ESCL JAM warning signal within 10 seconds or until the active
command deactivation conditions will be met, if jam is occurred when the electric steering motor is
locked/unlocked.
Failure Detecting Conditions
When the UNLOCK retry occurs after ESCL LOCK command, the ESCL LOCK is performed.
- The UNLOCK retry is possible up to 2 times automatically. If the UNLOCK retry occurs 3 times
in succession, the ESCL NOT LOCKED warning is triggered.
- Reactivates when the ESCL LOCK conditions are met.
When the LOCK retry occurs after ESCL LOCK command, the command will be overridden without
retry.
- After the command is overridden, the ESCL NOT LOCKED warning is triggered.
- Reactivates when the LOCK conditions are met by pressing the START/STOP switch after
ESCL UNLOCK.
When the LOCK retry occurs after ESCL UNLOCK command, the ESCL UNLOCK is performed.
- The LOCK retry is possible up to 2 times automatically. If the LOCK retry occurs 3 times in
succession, the ESCL JAM warning is triggered.
- Reactivates when the ESCL UNLOCK conditions are met by pressing the START/STOP
switch.
When the UNLOCK retry occurs after ESCL UNLOCK command, the command will be overridden
without retry.
- After the command is overridden, the ESCL JAM warning is triggered.
- Reactivates when the UNLOCK conditions are met by pressing the START/STOP switch after
ESCL LOCK. 1.

12. SKM IMMOBILIZER SYSTEM
1) System Description
The immobilizer system prevents the vehicle theft by allowing only the authorized key to start the engine.
The transponder inside the key communicates with the SKM (immobilizer slot) and EMS (ECU) through
P-CAN communication, and the system permits the engine to start after confirming the encrypted
coding.
When the START/STOP switch is pressed with the smart key inserted into the immobilizer slot because
of the smart key battery discharge, the SKM communicates with the EMS (ECU) through P-CAN, and
the ECU starts to control the engine only the signal is valid.
A valid key verification time is provided for 10 seconds and the engine can be started during this time. If
pressing the START/STOP switch again after this 10 seconds, the key verification process is performed
again.
2) Configuration
Emergency slot
Smart key
SKM
EMS (ECU)

3) Operating Process
Key verification can be divided into two types, immobilizer key verification and smart key verification. The
immobilizer verification is applied for the SKM system, and verifies the transponder built in the smart key.
When the smart key is inserted into the slot, the verification is carried out, overriding the RF signal from
the smart key.
The power is supplied to the slot when the START/STOP switch is pressed with the smart key inserted
into the slot, and the smart key transponder verification is carried out by the transponder communication.
Once the key is verified, a valid key verification time is provided for 10 seconds and the engine can be
started by pressing the START/STOP switch during this time. If pressing the START/STOP switch after
this 10 seconds, the key verification process is performed again.
When the ignition is turned ON, the EMS (ECU) sends the challenge message to the SKM through
the P-CAN. (This is to verify whether the transponder of the smart key is valid. If the verification fails,
it transmits the re-verification signals 3 times for 2 seconds. If 3rd re-verification fails, the verification
is deactivated for 10 seconds and re-activated after that.)
The immobilizer slot of the SKM system sends the encrypted cod to the transponder, and the
transponder re-sends the encrypted code to the immobilizer slot.
The encrypted sent to the immobilizer slot is re-sent to the SKM.
The SKM compares this code with the encrypted code randomly transmitted by the internal logic.
(System compares the signal from transponder and encrypted signal from the immobilizer control
unit)
Only when the two signals are identical, it recognizes the key as the verified one and transmits the
positive message to the ECU.
The ECU enables the engine to be started. 1.
