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. See also 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 .
