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 flasher control (coupled with ABS) ▶
System layout 1.
Operating conditions: When receiving the emergency hazard flasher ON signal from ESP and ABS.
When receiving the emergency stop signal through PCAN communication it blinks with the interval of
4 Hz and when receiving the emergency stop OFF signal through PCAN communication it blinks with
the interval of 1.25 Hz, normal operating speed.
However, the manual operation of the switch has a priority over this function. 2.
Priority
Manual hazard flasher > Emergency stop signal > Emergency auto hazard flasher > Auto hazard
flasher
(If emergency stop signal is received through PCAN communication during hazard flasher
operation, the signal is overridden. If the emergency hazard flasher signal is received during multi-
function automatic hazard flasher operation or multi-function automatic hazard flasher is received
during emergency hazard flasher operation, emergency stop is performed.)
When the emergency stop signal is received, the hazard flasher blinks with the interval of 4 Hz,
then returns to normal operation speed. After that, if the emergency stop signal is received again,
the emergency hazard flasher blinks with the interval of 4 times/sec. -

(2) Ignition status change
The ignition status is changed to OFF, ACC ON, IGN ON and engine cranking by one START/STOP
button.
The SKM cuts the power for IGN2 and ACC relays while the engine is cranking as cutting the electric
load is necessary.
The SKM monitors the brake pedal status through the hardware signals.
The ignition status change is available when the engine START/STOP button is pressed.
The SKM uses the EMS (engine condition) and ABS/ESP (FR vehicle speed) signals sent through the
P-CAN bus (High Speed CAN).
When the smart key battery is discharged and the driver inserts the smart key into the immobilizer slot
in emergency mode, the smart key verification is performed if the brake or START switch is pressed
before the ignition status is changed (ACC ON, IGN ON).

When the engine START/STOP switch is pressed for 3 sec. or more at more than 3 km/h, 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.
The 4 vehicle speeds are abnormal (CAN signal timeout, abnormal signal):
If the engine START/STOP switch is pressed for 3 sec., the ignition status is changed from IGN
to ACC. If the switch is pressed again, the ignition status is changed from ACC to OFF (DTC
set). -

The SKM changes the ignition status as follows: 8.
