While driving, AWD warning lamp flashes rapidly. (when it flashes for approximately 1 minute, then does
not illuminate.)
Rapid flashing: 2 times/second
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.

Inspection

AES000HC

ALUMINUM WHEEL

1.

Check tires for wear and improper inflation.

2.

Check wheels for deformation, cracks and other damage. If
deformed, remove wheel and check wheel runout.

a.

Remove tire from aluminum wheel and mount on a tire balance
machine.

b.

Set dial indicator as shown in the illustration.

STEEL WHEEL

1.

Check tires for wear and improper inflation.

2.

Check wheels for deformation, cracks and other damage. If
deformed, remove wheel and check wheel runout.

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 

WT-54, "SERVICE DATA"

SFA975B

Radial runout = (A+B)/2

Lateral runout = (C+D)/2
