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.

A/T assembly
Automatic transmission is available as 4WD- and 2WD-type,
and provides 6 speeds for forward travel and 1 reverse
travel. It is also equipped with the torque converter with inner
lock-up clutch and electronically controlled solenoid which
controls all hydraulic functions.
3. CHASSIS COMPONENT LAYOUT
PTU (Power Transfer Unit)
The PTU is a device that transfers the power
generated from the engine to the rear axle through
propeller shaft and E-coupling by changing the power

4WD vehicle.
Rear axle assembly
The rear axle installed in this car is a removable
axle, called IRDA (Independent Rear Differential
Axle). The rear differential carrier is installed
directly on the sub frame, and there is an
independent suspension that allows each wheel
on the same axle to move vertically independentl
y
of each other with the universal joint and the slip
joint.
E-coupling control unit (E-Coupling ECU)
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.

M6LF1 manual transmission
M6LF1 manual transmission is a model modified from the
one that used in other vehicle so that it can be applied to FF
(Front engine-Front wheel driving) type vehicle, and has an
axle in one piece. The engine torque and gear ratio of this
transmission have been optimized to maximize driving
performance. It provides 6 speeds for forward travel and 1
reverse travel.

(Front engine-Front wheel driving) type vehicle, and has an
axle in one piece. The engine torque and gear ratio of this
transmission have been optimized to maximize driving
performance. It provides 6 speeds for forward travel and 1
reverse travel.
The 2WD vehicle with manual transmission is a front wheel drive type vehicle that doesn't have PTU,
propeller shaft, E-coupling and rear axle which are applied to 4WD vehicle. Its under structure is very
simple.

Rear sub frame assembly for 4WD
The rear sub frame for 4WD vehicle consists of 4 body (bush)
mountings and 2 axle (direct) mountings which reduce the vibration from
the powertrain and road, and also control the torque.

The parking brake is the mechanical device to
hold the vehicle. When pulling up the lever, the
parking brake cable between the lever and the
rear drum brake trailing shoe pulls the parking
brake lining to contact to drum.

1. OVERVIEW
2WD4WD
The Model 6F24 6 speed automatic transaxle is electronically controlled. The control system is
comprised of the following components:
External transaxle control unit (TCU)
Input and output speed sensors
Six variable force solenoids(VFS) and two on/off solenoids
Torque converter
ATF temperature sensor -
-
-
-
-
TCU controls the oil pressure for various internal clutches and brakes to select the gear. It also controls
the electronic elements, shift pressure and torque converter slip. If the system is defective, TCU provides
FMEC (Failure Mode Effect Control) to maintain the functionality of transaxle. This keeps the basic
function of transaxle (gear selection) even when there are failure in controls and power supply.
There are selector shaft position sensor (inhibitor switch) and oil temperature sensor in transaxle. In
manual mode, TCU receives the information from TGS (Transmission Gear Selector) through PCB
(Printed Circuit Board) when driver selects the manual shift mode. TCU communicates with other electric
control modules through CAN. In order to ensure a safe driving state and to prevent damage to the
automatic transmission, TCU switches to Limp-Home mode in the event of critical faults.
