TRANSFER CASE
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 Morse Hi-Vo 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 occuring 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.
