LOW BATTERY VOLTAGE

If the battery voltage falls below 34 volts ±5%, the low battery voltage fault is detected by the speed controller.

THERMAL CUTBACK

If the controller heatsink temperature is found to be in excess of 85 °C ±5 °C (185 °F ±9 °F) or below –25 °C ±5 °C
(–13 °F ±9 °F), the thermal cutback fault is detected.

MOTOR STALL

If the motor current is high and there is no movement of the vehicle wheels for a short period of time, a motor stall is
detected by the speed controller. This fault can be caused by an operator holding the vehicle on a hill by depressing
the accelerator pedal instead of the brake pedal.

MAIN DROPOUT (1 OR 2)

If the controller detects that the solenoid contacts have opened while the vehicle is in operation, a main dropout fault
is detected.

INCORRECT PASSWORD (IQDM-P ONLY)

Each vehicle has a password in the form of a unique set of codes used to place the vehicle in "private speed mode". If
a set of codes has been entered incorrectly, the incorrect password fault is declared. For additional information on
codes, refer to Code A, Code B, and Code C. See Code A, Code B, and Code C on page 22-4.See also Password
Tries (IQDM-P Only) on page 14-7.

MAX PASSWORD TRIES (IQDM-P ONLY)

The max password tries fault is declared when the incorrect password fault has been declared several times. In the
event that the max password tries fault is indicated, the speed controller must be removed and shipped to Club
Car before it can ever be placed in "private speed mode". See Code A, Code B, and Code C on page 22-4.See
also Password Tries (IQDM-P Only) on page 14-7.

FAULT HISTORY

The fault history menu can be useful in determining the cause of a vehicle problem; however, the fault history alone
should not be the factor that determines when a component is replaced. Some faults detected by the speed controller
are not the result of a failed component, and are instead the result of vehicle operator error. If a fault appears in the
fault history menu, the trained technician should attempt to determine when and where the fault has occurred. For
example, if the motor stall fault is present in the fault history, the trained technician may be able to determine the
location on the course where an operator has held the vehicle on a hill by using the accelerator pedal.
