2) 4WD Operation Overview
To make the mode shift easier, stop the vehicle, depress the brake pedal, select the mode
switch, and move the selector lever with the sequence of [N-P-N].
3) Mode Switch
Selection Mode ▶
The TOD system has 2 selectable mode, 4H and 4L.
4H is the normal operating mode when drive of which gear ratio is 1:1 and 4L mode distributes
power to front and rear wheels 50:50 of which gear ratio is 2.48:1.
4L Mode ▶
When selecting 4L mode, EMC is locked to apply maximum torque into front and rear propelle
r
shafts (when the wheel speed is more than 87Hz).
Shift motor rotates also 4L position by rotation of cam thus propeller shaft torque changes from
1:1 to 2.48:1 by planetary gear set.
Releasing the 4L Mode ▶
When selecting 4H mode, 4L drive mode is
released and 4H mode is resumed.
“4H” switch: Self-return type
“4L” switch: Push lock type ·

1. PROPELLER SHAFT GENERAL INFORMATION
The propeller shaft transfers the power through
the transmission and transfer case to the
front/rear axle differential carrier (final reduction
gear). It is manufactured by a thin rounded steel
pipe to have the strong resisting force against
the torsion and bending. Both ends of propelle
r
shaft are connected to the spider and the cente
r
of propeller shaft is connected to the spline to
accommodate the changes of the height and
length. The rubber bushing that covers the
intermediate bearing keeps the balance of rea
r
propeller shaft and absorbs its vibration.
