DRIVE LINE CONTROL SYSTEM (TOD)

Front and Rear Speed Sensors

The sensors are built in the transfer case, and detect the
rotation of rotors directly coupled to the propeller shafts.
Thirty rectangular pulses are output per one rotation of
the propeller shaft.

261RW045

Electromagnetic Coil

Receives the duty signals from the TOD control unit and
controls the pressing force of the clutch pressure cam.

261RW044

Multi Plate Disk Clutch Pack

Transmits the torque determined by the clutch pressing
force to the front propeller shaft via the front drive chain.

262RW029

Mechanical Lock Sleeve

Couples the front and rear propeller shaft mechanically
when the transfer shaft is in the 4L position.

DRIVE LINE CONTROL SYSTEM (TOD)

4B2–6

High-Low Planetary Gear Set

Establishes an auxiliary transmission mechanism. When
the TOD switch is set to the 2H or TOD position, the
reduction gear ratio is 1.000 and the corresponding
driving force is generated. When the TOD switch is set to
the 4L position, the reduction gear ratio is 2.480 and the
corresponding driving force is generated.

262RW030

4H and 4L Switch

Detects the shift position of the transfer from the
movement of the shift rod and outputs signals to the TOD
control unit.

261RW002

Transfer Connector (12-pin type)

Transmits the input and output signals of the speed
sensors, electromagnetic coil, and 4H and 4L switche to
the vehicle harness. A waterproof 12-pin type is used.

261RW046

Transfer Connector (8-pin type)

Transmits the output signals of the shift motor position to
the vehicle harness and power for the shift motor to the
transfer. A waterproof 8-pin type is used.
