IQ DISPLAY MODULE (IQDM) SERIES 2 AND
IQDM-P DIAGNOSTICS
Faults Menu
23
12 Main Dropout
If the controller detects that the solenoid contacts have opened while the vehicle is in operation, a
main dropout
fault
is detected.
13 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.
14 Main Driver Off
If the FET that controls the activation of the solenoid coil is
not
energized when it should be, a
main driver off
fault is
detected by the speed controller.
15 Relay DNC
If the external Walk Away Relay contacts do not close, a
relay dnc
is detected.
16 Keyswitch SRO
If the key switch is in the ON position when the controller is powered up, a
key switch sro
fault is detected. This fault
detection feature may be turned on or off with an IQDM. Factory default setting is off.
17 Current Sense
If there are problems with the armature current sensor circuitry, a
current sense
fault is detected.
18 M- Shorted
If an uncontrolled current path is detected from the motor to B- (bypassing the MOSFETs), an
M- shorted
fault
is detected.
20 Driver Overcurrent
If the current on the relay driver exceeds 120 mA, or the current on the solenoid driver exceeds 6A, a
driver overcurrent
fault is detected.
21 Precharge Fault
If the internal precharge circuit fails, or there is a short between the B+ and B- controller terminals, a
precharge
fault
is detected.
22 Field Missing
If the speed controller is operating at a duty cycle of greater than 90% (almost full speed) and the field current is less
than 3 amps, a
field missing
fault is detected by the speed controller.
23 Relay Driver On
If the relay driver has been commanded to turn OFF, but remains on, a
relay driver on
fault is detected.
24 HW Failsafe
If the speed controller detects a failure of the armature drive FETs or circuitry, an
hw failsafe
fault is detected.
25 Incorrect Password
If an incorrect attempt is made to activate Mode 2 by entering Code A, Code B, Code C, an
incorrect password
fault
is detected.
26 Circuit BRKR Open
If the circuit breaker element in the Walk Away circuit is blown, or not wired to the controller, a
circuit brkr open
fault
is detected.
27 Max Password Tries
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 Mode 2.

Password Tries (IQDM-P only) on page 23-6.
29 Relay DRVR Off
If the Walk Away relay driver FET remains in the OFF state when commanded to switch on, a
relay drvr off
fault
is detected
