This phenomenon protects drivetrain parts when a heavy load is applied to the electric controlled coupling
and multiple disc clutch temperature increases. It is not a malfunction.
When the difference of revolution speed between the front and rear wheel with AUTO mode, the shift
switch occasionally changes to LOCK mode automatically. This is not a malfunction.
WHILE DRIVING, AWD WARNING LAMP FLASHES SLOWLY. (WHEN IT CONTINUES TO ILLU-
MINATE UNTIL ENGINE TURNS OFF.)

a.
Remove tire from steel wheel and mount wheel on a tire balance
machine.
b.
Set two dial indicators as shown in the illustration.
c.
Set each dial indicator to 0.
d.
Rotate wheel and check dial indicators at several points around
the circumference of the wheel.
e.
Calculate runout at each point as shown below.
f.
Select maximum positive runout value and the maximum nega-
tive value.
Add the two values to determine total runout.
In case a positive or negative value is not available, use the
maximum value (negative or positive) for total runout.
If the total runout value exceeds the limit, replace steel wheel.
Wheel runout (Dial indicator value):
Refer to
