SYMPTOM CAUSE REQUIRED ACTION
Blocked or faulty fan
With VGM power on, check airflow near each
computer fan. Case cooling fans are intake fans.
Power supply fan is exhaust fan. Assure that
nothing blocks airflow.
Faulty mechanical
parts
Turn off VGM power. Open dashboard. Support
steering wheel and remove outer mounting
screws. Remove metal shield (if your 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. LEDs glow if motor driver circuits
receive AC power from transformer. (Voltages or
signals may or may not be normal.)
2. Examine fuses and cables on Wheel Driver
Board. Replace bad fuses. Using digital
voltmeter, verify AC voltage between each fuse
holder and ground. You should measure
approximately 25V. See Wiring Diagram.
3. Using 20 VAC setting on digital voltmeter,
measure DC voltage at motor. Don’t move
steering wheel, drive belt, or motor while making
this measurement. Any reading indicates
unstable supply that may contain ripple or noise.
4. Verify proper operation of Wheel Driver Board by
placing it in working VGM.

Sloppy, unpredictable or
ineffective steering

Video appears on screen
•
VGM (video game machine)
starts normally
Loose or worn drive
belt
1. Turn off VGM power. Open dashboard. Support
steering wheel and remove outer mounting
screws. Remove metal shield (if your 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.
Improperly set
feedback
1. From Diagnostics Menu, choose FORCE
FEEDBACK ADJUSTMENT.
2. Set feedback to match player requirements.
Maximum force may be too extreme for very
young or inexperienced customers.
Faulty circuit
1. Examine fuses and cables on Wheel Driver
Board.
2. Check cables and wiring between computer,
interface, driver and motor.
3. Check resistance of motor series resistors
4. Replace bad parts.

expected
Faulty motor
1. Turn off VGM power. Open dashboard. Support
steering wheel and remove outer mounting
screws.
2. Remove metal shield (if you VGM has one) over
motor.
3. Unscrew caps.
4. Inspect motor brushes. Replace worn parts.
