Power control and engine start diagram

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.

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.
the driver door is opened with ACC ON.
(Driver door open signal input through B-CAN)

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.
If the theft deterrent mode is activated by the LOCK signal from the passive or REKES key when
The ESCL LOCK is performed after 60 seconds since the ignition key is turned to B+ from

11. SKM WARNING CONTROL
(1) Smart Key Not Detected Warning
With ACC ON
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.

(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. -
