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.
