TRANSFER CASE
TANSFER CASE
INTRODUCTION
The Transfer Case is a two speed, part time
electric shift transfer case. It provides three
operating positions i.e. 2H - Two High, 4H - Four
High & 4L - Four Low.
In 2H and 4H positions the transfer case operates
at 1:1 speed ratio. In 4L position it operates at
2.48: 1.00 speed reduction ratio. Power transfer to
front wheel is through a chain and a planetary gear
set.
(For gear reduction.)
The operation is controlled by the Electronic
Control Unit (ECU). When the rotary selector
switch is operated the ECU intelligently controls
operations by sensing the conditions and then
shifts transfer case into the selected mode.
ECU self diagnoses any fault occurring in the
system. These faults are stored in ECU are
displayed as binary codes.
Electromagnetic shift on the fly provides effortless
Engagement of four wheel drive at highway
speeds.
Selector switch is provided for different modes, it
simplifies selection of operating modes.
Positive displacement oil pump and filter assure
full lubrication while driving or towing.
