TRANSFER CASE (TOD)
General Description
A04R200003
The Torque-On-Demand (TOD) is an
electronically-controlled torque-split 4-wheel drive
system with the following features.
Shifting Between High and Low Ranges
The shifting mechanism consists of the cam and shaft rail
assembly, the high/low shift motor and the encoder. The
encoder is built-in to the motor.
The encoder senses high/low range shift motor rotation
position and sends this data to the TOD control unit.
Based on this data, the TOD control unit adjusts motor
rotation speed or stops the motor.
The shifting between the high and low ranges using the
TOD switch only is possible. The vehicle must be stopped
or nearly stopped (vehicle speed less than 2 km/h (1.2
mph) and engine speed less than 1,500 rpm), the
automatic transmission selector level must be in the
neutral (N) position, and the brakes must be applied.
Electronically-controlled Wet-type Multiple
Disc Clutch
The clutch automatically provides the optimum drive
power to the front wheels of the vehicle in response to
varying road surface conditions when the vehicle is
operated in the TOD mode. The delivered power ranges
from 0% to 100% of power train output. Superior
operational stability is maintained over a wide range of
operating conditions.
Front Output Drive
Front output drive is provided by a chain. This reduces the
loud noise associated with 4-wheel drive operation.
Oil Pump Lubrication
An oil pump is used to lubricate the transfer. This ensures
stable multiple-disc clutch operation and maintains the
lubricating oil at a constant temperature.
