SYMPTOM CAUSE REQUIRED ACTION
Blocked or faulty fan Fan located on power supply functions as an
exhaust fan. With power on, check airflow near
each fan to assure that nothing blocks airflow.
Faulty mechanical
parts Turn off power. Open dashboard. Support
steering wheel and remove outer mounting
screws. Remove metal shield (if VGM has one)
over motor. Inspect for faulty or worn belts,
bearings, couplings, gears, etc.
Faulty Wheel Driver
Board 1. Inspect Wheel Driver Board under low-light
conditions. To indicate presence of AC from the
transformer the LED’s glow when voltage is
received. However, voltages or signals may not
be normal.
2. Examine fuses and cables on Wheel Driver
Board. Replace bad fuses. Use digital voltmeter
to verify AC voltage between each fuse holder
and ground. You should measure approximately
25V. See Wiring Diagram.
3. Use the 20-VAC setting on digital voltmeter to
measure DC voltage at motor. Do not move
steering wheel, drive belt, or motor while making
this measurement. Any reading indicates
unstable supply that may contain ripple or noise.
4. Select the STEERING WHEEL TEST from the
Diagnostic Menu. Follow on-screen instructions
to verify operation of the wheel motor and
steering position sensor.
5. Verify proper operation of Wheel Driver Board by
placing it in working VGM.

Loose or worn drive
belt 1. Turn off power. Open dashboard. Support
steering wheel and remove outer mounting
screws. Remove metal shield (if VGM has one)
over motor. Inspect for faulty or worn belts,
bearings, couplings, gears, etc.
2. If drive belt isn’t worn or damaged, check its
tightness.
•
Inability to make a
