PRECAUTIONS FOR DIAGNOSIS

M1274000500055

• After troubleshooting, and removing/installing of

the electronic control AWD system components,
check the diagnostic trouble code using scan
tool. If a diagnostic trouble code is set, erase it
and check again that no diagnostic trouble code
is set.

• Before performing a troubleshooting, check that

all four wheels and tires are same in size, in type,
and in brand. The electronic control AWD system
will function correctly only when all four wheels
and tires are same in size, and tire pressure is
specified value.

• If any abnormality occurs in the electronic control

AWD system, it flashes the indicators (4WD and
LOCK) in the combination meter alternately to
inform of the abnormality.

• When the vehicle is used under some severe

operational conditions (such as a long-time driv-
ing in AWD on a sandy road, slushy road or road
with deep snows or towing or long hill-climbing),
the electronic control AWD system illuminates the
drive system fluid temperature warning display in
the combination meter in order to protect the
electronic control coupling fluid, at the same time
it flashes the indicator (4WD or LOCK) corre-
sponding to the selected drive mode to inform of
the abnormality.

• The electronic control AWD system is equipped

with the fail-safe function which prohibits AWD
control and shifts to FWD control if any abnormal-
ity occurs in the system. If there is a risk that the
vehicle behavior suddenly changes, the gradual
shifting to FWD control is chosen.
