General Information, Continued:
• Pedal Up Motor Braking: When vehicle speed is above 11 mph (17.7 km/h), releasing the accelerator
pedal will activate motor braking, which slows the vehicle speed. Once vehicle speed slows to below
approximately 11 mph (17.7 km/h), with the accelerator pedal still released, motor braking will be deac-
tivated and the vehicle will coast freely. This feature is selectable. Contact your Club Car dealer/distrib-
utor to inquire about this selectable feature.
• Regenerative Braking : When motor braking is activated, the vehicle motor acts as a generator, slow-
ing the vehicle as it creates energy that is used to charge the batteries.
• Tow/Run Switch: When the Tow/Run switch is in the RUN position, the vehicle will function normally.
When the switch is in the TOW position, power to the OBC and controller is shut off, disabling the vehi-
cle operating circuit and zero speed detect, allowing the vehicle to be towed.
• Motor Protection Circuit: The operator should never attempt to hold the vehicle on an incline by press-
ing the accelerator pedal instead of the brake pedal, as motor overheating could result. By reducing the
current to the motor during such an occurrence, the motor protection circuit reduces the possibility of
motor damage. When this situation arises, a
motor stall fault is recorded by the speed controller and will
be displayed on an IQDM handset in the Diagnostic History menu. See the IQDM Owner’s Manual.
• High Pedal Detect: This function prevents unexpected vehicle movement if the key switch is turned
ON after the accelerator is pressed, or the accelerator pedal is pressed when Forward/Reverse switch
is used to change the direction of travel. The vehicle will not move until the accelerator is released and
pressed again. When this situation arises, a
HPD fault is recorded by the speed controller and will be
displayed on an IQDM handset in the Diagnostic History menu. See the IQDM Owner’s Manual.
• Onboard Computer (OBC): The OBC, 1) monitors battery condition, 2) monitors the number of
energy units used by the vehicle, 3) determines the number of energy units required to recharge the
batteries and shuts the charger off when this number is reached, 4) determines when to activate regen-
erative motor braking, 5) locks out vehicle movement while the charger is plugged into the vehicle
charger receptacle, 6) stores operating data, which can be read by the Communication Display Module
(CDM).
See Communication Display Module (CDM) on page 11-38.
TROUBLESHOOTING
The following troubleshooting guides will be helpful in identifying operating difficulties should they occur. The
guides include the symptom, probable cause(s) and suggested checks. The procedures used in making these
checks can be found in the referenced sections of this maintenance and service manual.
TROUBLESHOOTING THE VEHICLE WITH THE IQDM
Club Car recommends the use of the IQDM handset for troubleshooting vehicles equipped with the IQ elec-
trical system. Troubleshooting Guide 1 is to be used in conjunction with the IQDM handset. Refer to the IQDM
Owner’s Manual for operating instructions.
See following WARNING.

WARNING
• The vehicle operator should not monitor the IQDM while the vehicle is in motion. A technician
can monitor the IQDM while traveling as a passenger in the vehicle. Failure to heed this
warning could result in severe personal injury or death.
In the event that the vehicle is not functioning properly after completing Troubleshooting Guide 1, the techni-
cian should proceed to Troubleshooting Guide 2.
If an IQDM handset is unavailable, the technician should proceed to Troubleshooting Guide 2.
