(1) OVERVIEW
The part time transfer case achieves direct connection from the power of the rear wheels to
the power of the front wheels by the lock up hub when selecting 4WD "HIGH" and the powe
is supplied by the sealant chain in the transfer case.
The simple operation of switches on instrument panel allows to shift between “2H” and
“4H” easily while driving.
The warning lamp warns the driver when the system is defective.
The 4WD system integrated in KYRON does not have big difference in comparison to the
conventional part time transfer case, but the changes in comparison to the conventional
transfer case are as follows
No additional coding is required when replacing TCCU.
