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 mechani-
cal 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 condi-
tions. To indicate presence of AC from the trans-
former 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 Wir-
ing Diagram.
3. Use the 20-VAC setting on digital voltmeter to
measure DC voltage at motor. Do not move steer-
ing 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 tight-
ness.

From the Diagnostics Menu, choose DIP SWITCH
TEST. Make sure DIP 1, SW 1 is set to the OFF posi-
tion.
