Test
A: INSPECTION
Check the transfer clutch pressure in accordance
with the following steps in the same manner as with
line pressure. Test.>

ASSYNOTE:
Before setting in FWD mode, install the spare fuse
on FWD mode switch.
NOTE:
If the oil pressure is not produced or if it does not
change in the AWD mode, the transfer duty sole-
noid or transfer valve assembly may be malfunc-
tioning. If the oil pressure is produced in the FWD
mode, the problem is similar to that in the AWD
mode.
