Motor Stall; Main Dropout (1 Or 2); Current Sense Fault; Incorrect Password (Iqdm-P Only) - Club Car 2009-20011 Electric Precedent Maintenance And Service Manual

IQ DISPLAY MODULE (IQDM) AND IQDM-P
DIAGNOSTICS: EXCEL SYSTEM
What to do: Monitor Heatsink Temp, battery voltage, brakes dragging, car under extreme loads, low or no air
pressure in tire(s).

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.
What it means: This fault appears anytime current is running to the motor and no movement of the armature
is registered.
What to do: In most cases this is an operator issue holding the vehicle on an incline with the accelerator pedal,
not 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.
What it means: Occurs when the solenoid coil losses ground causing the main contact to lose connection. With Main
Dropout 2, the solenoid drops out while the vehicle is in regen/motor braking.
What to do: Check the following components: key switch, MCOR, batteries, battery cables, FNR, solenoid coil,
solenoid contacts, and controller 16-pin connector.

CURRENT SENSE FAULT

If there are problems with the armature current sensor circuitry, a current sense 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 23-4.See also Password
Tries (IQDM-P Only) on page 16-6.

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 23-4. See
also Password Tries (IQDM-P Only) on page 16-6.

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
