fully turned at low speed:
1) Determine the applicable trouble code and check the
corresponding duty solenoid C (transfer) for improper
operation.
2) If the solenoid is operating properly, check transfer
clutch pressure.
3) If oil pressure is normal but“tight-corner braking”
occurs:
Check the transfer control valve for sticking, and the trans-
fer clutch facing for wear.
