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
operates 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 and 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 the indicator on the instrument panel.
6. Transmission of the position signal to other controllers.
