IQ DISPLAY MODULE (IQDM) AND IQDM-P
DIAGNOSTICS: EXCEL SYSTEM WITH
POWERDRIVE CHARGER
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. Main Dropout 2 is usually a symptom
more than a cause.
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
What it means:
If there are problems with the armature current sensor circuitry, a
current sense
fault is detected.
What to do:
Clear the Fault History in the IQDM. If the fault does not return and the car operates normally, do
not replace the controller. If the fault remains in System Faults or Fault History after clearing and the car will not
operate, replace the controller.
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 12-4.See also Password
Tries (IQDM-P Only) on page 11-7.
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 12-4. See
also Password Tries (IQDM-P Only) on page 11-7.
