8) SKM Warning Control
(1) Smart key not found warning (Key out warning)
If no verified smart key is identified as being in the vehicle with IGN ON or ACC ON, the SKM sends the
signal, which identifies that there is no verified key inside the vehicle, to the BCM and instrument cluster
through the BCAN (Smart key not found warning). This warning continues for up to 10 sec. until the
warning condition is deactivated.
The SKM stops the warning immediately after the warning condition is deactivated.

3) Cruise Control Switch
Cruise control switch
The cruise control is an automatic speed control system that maintains a desired driving speed without
using the accelerator pedal. The cruise control switch is fitted to the bottom right section of the steering
wheel. When this switch is operated, the AUTO CRUISE or ECO lamp on the instrument cluster comes
on.
The cruise control switch has a fivefold switch in it. The engine ECU can determine the current driving
condition since the resistance varies depending on the operation of the switch.
The cruise control system is operated at vehicle speed of between 38 km/h and 150 km/h. The manual
transmission is operated in the range of 3rd gear or higher.
This function can be used at the following traffic condition. (It is important to be careful for using this
function)
Cruise control (ON)
Cruise control (OFF)
Cruise control (Acceleration)Cruise control (Deceleration)
Cruise control (Reset)

G-sensor(4WD, ABS)
For the vehicle with the ABS, a speed difference
between the wheels is not noticeable as all the
wheels are slipping during abrupt braking.
Therefore, the vehicle needs the speed information
from other sensors other than the wheel speed
sensor. The longitudinal acceleration sensor (G-
sensor) is used for this case. It controls the ABS by
using the signals from the sensor during abrupt
braking and acceleration.
TCU unit
The transmission control unit (TCU) is installed under
the driver seat, and controls the transmission. The
TCU is operated by the ignition power supply and
receives and processes the following information from
the inner sensors through CAN buses.E-coupling unit
The E-coupling unit is a control unit which
determines the magnetic force by
considering CAN signals (wheel speed,
engine torque, pedal opening, ABS/ESP
CAN signals, etc.) from other ECUs.
TGS Lever assembly
The TGS communicates with TCU
(Transmission Control Unit), ECU,
ESP HECU and instrument cluster
to let the driver select the desired
transmission gear and to maintain
the desired driving condition. Also,
the tip switch is installed on the
lever knob and the steering wheel
so that the driver select the gear
manually when the shift lever is in
"M".Sensor cluster
The sensor cluster is linked to
the sensors on the unit board
and CAN interface. And they
are housed in one case and
mounted to the body.
