AWD Function
If "tight-corner braking" occurs when the steering wheel is 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 transfer clutch facing for wear.
