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. -

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.

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
