Repair Instructions
Wheel Discs InspectionS6RW0D2406006
Inspect each wheel disc for dents, distortion and cracks.
A disc in badly damaged condition must be replaced.
Wheel Balance Inspection and AdjustmentS6RW0D2406001
Refer to “Balancing Wheels Description”.
Deposits of mud, etc. must be cleaned from inside of rim.
WARNING!
Stones should be removed from the tread in
order to avoid operator injury during spin
balancing and to obtain good balance.

Each tire should be inspected for any damage, then
balanced according to equipment manufacturer’s
recommendation.
Off-Vehicle Balancing
Most electronic off-vehicle balancers are more accurate
than the on-vehicle spin balancers. They are easy to use
and give a dynamic (two plane) balance. Although they
do not correct for drum or disc unbalance as does on-
vehicle spin balancing, this is overcome by their
accuracy, usually to within 1/8 ounce.
On-Vehicle Balancing
On-vehicle balancing methods vary with equipment and
tool manufacturers. Be sure to follow each
manufacturer’s instructions during balancing operation.
WARNING!
Wheel spin should be limited to 55 km/h (35
mph) as indicated on speedometer.
This limit is necessary because speedometer
only indicates one-half of actual wheel speed
when one drive wheel is spinning and the
other drive wheel is stopped.
Unless care is taken in limiting drive wheel
spin, spinning wheel can reach excessive
speeds. This can result in possible tire
disintegration or differential failure, which
could cause serious personal injury or
extensive vehicle damage.

CAUTION!
For vehicle equipped with ABS, using on-
vehicle balancing method with ignition
switch ON may set malfunction diagnostic
trouble code (DTC) of ABS even when system
is in good condition.
Never turn ignition switch ON while spinning
wheel.

Tire RotationS6RW0D2406002
To equalize wear, rotate tires periodically as shown in
figure.

4WD Position Indicator Remains ON Steady at Ignition Switch ONS6RW0D3204014
Wiring Diagram
Refer to “4WD Position Indicator Does Not Come ON at Ignition Switch ON but Engine Stops”.
Circuit Description
Transfer position indicator operates according to the signal from 4WD control module. If the 4WD control system is in
good condition, 4WD position indicator light up for 2 seconds when ignition switch is turned to ON position, and then
turned to OFF position. If an abnormality is detected in the system, 4WD position indicator remains lighting.
Troubleshooting3CAN communication circuit check
1) Check CAN communication circuit between combination
meter and 4WD control module referring to “DTC U0073:
Control Module Communication Bus Off”.
Is CAN communication circuit in good condition?Go to Step 4. Repair or replace.
4“METER” fuse check
1) Turn ignition switch to OFF position.
2) Check for fuse blown to “METER” fuse in junction block
assembly.
Is “METER” fuse in good condition?Go to Step 5. Replace “METER” fuse
and check for short.
5Combination meter power supply check
1) Remove combination meter referring to “Combination
Meter Removal and Installation in Section 9C”.
2) Check proper connection to “WHT/RED” and “BLK” wire
terminal of combination meter connector.
3) If OK, then turn ignition switch to ON position and
measure voltage between “WHT/RED” wire terminal of
combination meter connector and vehicle body ground.
Is it 10 – 14 V?Go to Step 6. “WHT/RED” wire is
open circuit.
6Combination meter ground circuit check
1) Turn ignition switch to OFF position.
2) Measure resistance between “BLK” wire terminal of
combination meter connector and vehicle body ground.
Is resistance 1
Ω or less?Substitute a known-
good combination meter
and recheck. If 4WD
position indicator still
remains OFF, substitute
a known-good 4WD
control module and
recheck.“BLK” wire is open or
high resistance circuit. Step Action Yes No
Step Action Yes No
1Check DTC
1) Check DTC referring to “DTC Check”.
Is there any DTC(s)?Perform DTC flow to
repair and retry.Go to Step 2.
2CAN communication circuit check
1) Check CAN communication circuit between combination
meter and 4WD control module referring to “DTC U0073:
Control Module Communication Bus Off”.
Is CAN communication circuit in good condition?Substitute a known-
good combination meter
and recheck. If 4WD
position indicator still
remains off, substitute a
known-good 4WD
control module and
recheck.Repair or replace.
