ALL WHEEL DRIVE (AWD) DIAGNOSIS
Symptom: AWD Will Not Engage
1. Check the gearcase coil resistance. To test the coil
resistance, measure between the power wire
q
(GY)
and ground wire
w
(BN/WH). Measurement should
be within specification.
Front Gearcase Coil Resistance:
21.6 - 26.4 Ω
2. Turn the ignition and AWD switches on and place
gear selector in High or Low gear. Check for minimum
battery voltage at the Gray and Brown/White chassis
wires that power the coil. A minimum of 11 volts DC
should be present.
3. If electrical tests are within specification, remove
gearcase (see
FRONT GEARCASE REMOVAL
) and
inspect components.
4. Inspect armature plate
e
for a consistent wear
pattern. There should be two distinct wear bands
r
.
If only one band of wear is present (or if there is wear
between the two bands), inspect the coil area as
indicated in Step 5. A wear band with an interrupted
wear mark may indicate a warped plate, which may
cause intermittent operation.
5. Check to make sure the coil
t
is seated in the U-
shaped
y
insert that is pressed into the gearcase
cover
u
. The top of the coil should be seated below
the U-shaped insert. The U-shaped insert controls the
pole gap. If the top of the coil is above the surface of
the U-shaped insert it raises the armature plate,
thereby increasing pole gap. If the pole gap increases
the coil will not be strong enough to engage the AWD
system. If this is found, replace the cover plate
assembly.
6. Inspect the roller surface on the inside of the ring gear
for gouging/rough spots.
7. Inspect the roll cage
o
assembly for cracks or
excessive wear. If damaged, replace the roll cage
assembly.
8. Inspect the rollers
a
for nicks and scratches. The
rollers must slide up, down, in and out freely within
the roll cage sliding surfaces and H-springs.
