TRANSFER CASE 7D-3

General Description

RUW34DLF000701
The transfer case is used to provide a means of
providing power flow to the front axle. The transfer case
also provides a means of disconnecting the front axle,
providing better fuel economy and quieter operation
when the vehicle is driven on improved roads where
four wheel drive is not required. In addition, the transfer
case provides an additional gear reduction when placed
in low range, which is useful when difficult off-road
conditions are encountered.
Use the 4WD switch on the center cluster panel to
select the drive range. The 4WD indicator lamp will be
lit when 4WD is selected.

7D1-4 TRANSFER CONTROL SYSTEM
Summary of transfer control system
The transfer control system switches between the 2-wheel
drive (2H), 4-wheel drive high-speed (4H), 4-wheel drive low-
speed (4L), and neutral positions electrically when the driver
operate the switches.
This system has following functions.
1. Connection or disconnection of drive force distribution to
the front wheel front shaft (axle shaft) (The drive force
distribution to the front propeller is connected o
r
disconnected with the motor actuator.)
2. Try to repeat the connection or disconnection of the front
wheel drive function as described above.
3. Option: Shift on the fly type only.
Instruction of connection or disconnection of the drive force
transmission between the front wheel axle (axle shaft) and
front wheel
(The motor actuator connects or disconnects the left front
wheel ad front wheel axle (axle shaft).).
4. Shifting of auxiliary transmission gears, connection o
r
disconnection of wheel and engine drive force (4H, 4L,
neutral).
5. Operation of indicator on the instrument panel.
6. Transmission of position signal to other controllers.
