ALL WHEEL DRIVE (AWD) DIAGNOSIS
AWD WILL NOT ENGAGE
1. 2020 Models: 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:
22 - 24.3 Ω
2021+ Models: 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.
