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.

ABS/ESP
Vehicle 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.

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).
