1. OVERVIEW
By using the planetary gear sets, two-gears shift type part time transfer case achieves direct
connection when selecting 4WD "HIGH" and 2.48 of reduction gear ratio when selecting 4WD
"LOW". The silent chain in transfer case transfers the output power to front wheels.
The simple operation of switches on instrument panel allows to shift between "2H" and "4H" easily
while driving (for 4L: stop vehicle first). The warning lamp warns the driver when the system is
defective.

Operation ▶
Description Mode Conditions
Driving mode 2H 2 Wheel drive
(rear wheel)Rear-wheel drive mode. This is used under
normal or high-speed driving conditions on public
roads or highways.
4H 4 Wheel drive
(high speed)This is used under sandy, muddy or snow-
covered road conditions
4L 4 Wheel drive
(low speed)This is used for maximum traction.
When cornering with low speed in 4WD condition,
there could be tire dragging, some
mechanical shocks and resistances in vehicle’s
drive train. These are normal conditions due to
internal resistance in the drive train when the
4WD system is properly working

To make the mode change easily, stop the
vehicle on level ground and turn the mode
switch to the desired position and move the
shift lever to "N"-"R"-"N" while depressing
the brake pedal. For Automatic Transmission:
Stop the vehicle on level ground and move
the gear selector lever into the “N” position.
Turn the switch to the desired position. -
For Manual Transmission:
Stop the vehicle on level ground and move
the gear selector lever into the “N” position.
Then turn the switch to the desired position
while depressing the clutch pedal. -

(2) Vacuum System Related to 4WD
In 4WD mode, the TCCU blocks the
transferring of vacuum pressure from
vacuum pump to locking hub by supplying
the power to solenoid valve.Check valve
This valve allows the vacuum pressure to
flow through it in only one direction. This
prevent the vacuum from abruptly
releasing due to faulty vacuum pump.
4WD:
The vacuum pressure is released from the
hub actuator. At this time, the front hub end
gear is engaged.2WD:
The vacuum pressure pulls in the locking
hub actuator so that it will not be engaged
with the front end hub gear.

2) 4H Mode (4 Wheel Drive - High Speed)
Power Flow ▶
The driving force is pass through 4WD High magnetic clutch in transfer case and is distributed
on front wheels and rear wheels (50;50).

3) 4L Mode (4 Wheel Drive - Low Speed)
Power Flow ▶
The gear ratio is reduced to 2.48;1 while passing through 4WD Low range and planetary gear
set in transfer case and the driving force is distributed on front wheels and rear wheels
(50;50).
