TROUBLESHOOTING
PROBLEM SYMPTOMS TABLE
Use the table below to help you find the cause of the problem. The numbers \
indicate the priority of the likely
cause of the problem. Check each part in order. If necessary, replace these parts.
(w/ Differential locking system):
Check that center differential lock mode is set.
When switching differential Free↔Lock, the indicator lamp will blink if the gears of the differen-
tial lock sleeve are not meshed. If this occurs, when the tires are rotated \
to apply differential
power to the differential, the differential locks and the indicator lamp\
light up.
