2) Operation of DMF
Compensating the irregular operation of engine: The secondary flywheel operates almost evenly so
does not cause gear noises
The mass of the primary flywheel is less than conventional flywheel so the engine irregularity
increases more (less pulsation absorbing effect).
Transaxle protection function: Reduces the torsional vibration to powertrain (transaxle) by reducing
the irregularity of engine. -

Emergency hazard warning lamp control (coupled with ABS)
The emergency stop signal is input from the ABS/ESP module with the vehicle driven at 50 km/h or
more.
The hazard warning lamp flashes at 4 Hz (T1) and internal buzzer (chime) sounds at 1.25 Hz. A.
B. Operation 1. (emergency stop signal)
During operation 1 (emergency stop signal activated)
The vehicle speed decreased to 50 km/h or less
The hazard warning lamp flashes for 10 seconds (T2) at 1.25 Hz and then goes out. C.
D.
E.
The BCM activates emergency hazard warning lamp operation when receiving emergency braking
signal from the ESP/ABS.

lamp)
During operation 2 (emergency AUTO hazard warning lamp)
The hazard warning lamp switch is turned OFF.
The hazard warning lamp is turned OFF because the manual operation overrides the emergency
AUTO operation. F.
G.
H.
The emergency stop signal and emergency AUTO hazard warning lamp signal are switched off
when the vehicle speed exceeds 10 km/h (if emergency stop signal is input).

Operating process
The BCM activates emergency hazard warning lamp operation when receiving emergency braking
flasher ON signal from the ESP/ABS.
When the emergency stop signal is input through the P-CAN, the hazard warning lamp flashes with the
frequency of 4 Hz and the internal buzzer sounds at 1.25 Hz.
P-CAN signal during operation: Emergency Stop=EBL_INFO=0*0=Hazard Warning Lamp unrequested

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.

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). -

Immobilizer indicator
This indicator comes on when the passenger air bag OFF switch is operated.
This indicator comes on the immobilizer (transponder) is not certified. This lamp comes on when the parking brake is applied or the brake fluid
is insufficient.
If this lamp doesn't go off after the parking brake is released, check the
brake fluid level first and then fluid leakage. -

This warning light comes on when the ignition switch is turned to ON
and should go out if the system is normal -
This indicator comes on when the EPS system is faulty.

The pre-warning of the MICOM control warning is performed 400 ms after turning the ignition switch to
ON position.
IGN ON detecting time: 40~80 ms after turning ignition switch to ON position -
- The pre-warning is performed for 4 seconds after turning the ignition switch to ON position. BCM checks
that the warning lamps (ABS, ESP, ESP OFF, 4WD CHECK, 4WD LOCK) are matched with CAN
signals.
The pre-warning is performed by the variant code.
