Driving the car with the A-C Drive System
When key switch is first turned on, the system needs about 2 seconds to come
online. After this time has expired, select the desired drive direction at the
Forward/Reverse switch and press the accelerator pedal. The drive wheels could be
in either direction when first turned on.
BDI: (Dash Gauge), the BDI will display Battery Charge level (LED’s at bottom) as
well as text messages.

Street Mode gives the cart a Max speed of 25 Miles per hour. Acceleration &
Regenerative Brake torque are set at maximum level.
When in Golf Mode the cart speed is limited to 12 Miles per hour. Acceleration &
Regenerative Brake torque is also reduced.
Page 5 of 20
Drive Mode can be changed on “The Fly”. There is no need to stop the cart when
changing from Street to Golf or vice-versa.
When Cart is in Reverse, speed is reduced to 8 Miles per hour. Acceleration &
Regenerative Braking torque is also reduced.
Limp Home mode is automatically activated when the Battery charge level has
dropped below 20%. The maximum cart speed is restricted up to 15 Miles per
hour at Street mode. It is recommended to charge the batteries as soon as
possible to prevent damage to the batteries from being over discharged.

Instructions for Throttle Set Up
For systems set up after March 2007 with Version 8.00U software
With Key OFF, Select Forward Direction, Release Parking Brake, Press and hold the
“Menu” Button, then turn the Key “ON”. Hold Menu Button until “Program”
appears on the Dash Display, then release.
If the cart has a brake pedal switch:
Use the Brake Pedal to cycle through the options. Have the Golf/Street Mode
switch set to “Street Mode”, (MPH), to change parameters.
If the cart does not have a brake pedal switch:
Select “Golf Mode” and press the “Menu Button” to cycle through the options.
To change a parameter in any of the options:
Select “Street Mode” and press the “Menu Button” to change a parameter or
activate an option.
T Type: This is the Throttle Pot Type Parameter. For 0-to-5k, 2-wire throttle pots,
set to type 3. For 3-wire throttle pots or EZ Go with ITS converter box, set to Type
2. The default is Type 2.
Throttle: This allows the Throttle range to be calibrated.
Cycle the program options to “Throttle” on the Dash Display, select Street Mode,
press the Accelerator Pedal to the floor (Max Throttle).
With the pedal pressed, press and hold the “Menu” Button and the display will
show “HoldMenu”. Maintain the pedal and menu button pressed until the
display reads “Turn OFF”. After this message is displayed, turn off the Key. DO
NOT release the accelerator pedal or the Menu button before turning OFF the
Key. The Throttle is now calibrated.
Using this procedure will ensure full throttle range; if this procedure is not
performed the calibration will be at to a default setting. Use this set up procedure
for 2-wire, 0-to-5k, three wire throttle or EZ Go with ITS converter box types.
Page 7 of 20
Rst: This is the BDI reset voltage per battery cell. Adjust only if there is a problem
with the BDI resetting to 100% when the batteries are below 85% and have not
been charged or not resetting after a charge.
To increase the parameter, select “Forward” and “Street Mode”, then press the
Menu button.
To decrease, select “Reverse” and “Street Mode”, then press the Menu button.
The default is 2.125 volts per cell; this should work fine in most applications.
Mode: Sets the Motor Control Mode. The control mode can be set as Mode 1 or
Mode 2
Mode 1 is Speed Control. Speed Control means the accelerator pedal controls the
actual speed of the vehicle.
For example: In Speed Control Mode if you set the accelerator pedal to half, you
will go half speed, uphill, downhill or on flat ground. Speed Mode is great if you
are looking for controlled descents down hills and want to use the brakes a little
as possible. It does however have more of a jerky feel when changing speeds with
the accelerator pedal.
Mode 2 is Torque Control Mode. Torque control is the same type of control
method a DC motor has. The accelerator pedal controls the amount of torque the
motor produces. This gives a much smoother feel when changing the accelerator
position. Brakes will be used more in downhill descents.
Brk%: Only available if the Speed Mode is set to “2”. This sets the amount of
Regen when the Brake Pedal is pressed.
To increase the parameter, select “Forward” and “Street Mode”, then press the
Menu button. To decrease, select “Reverse” and “Street Mode”, then press the
Menu button.
If the default braking level is desired, leave this set to Zero. The Default is 40%. So,
setting to 1% would be the lowest setting and give almost no Regen.

Instructions for using On Board Diagnostics
With the Key OFF, Select Reverse Direction, Press and hold the “Menu” Button.
Turn Key the “ON”, hold Menu Button until “Diagnose” appears on the Dash
Display, then release the Menu Button. Pressing and releasing the menu button
will scroll through the Diagnostic options. The cart can be driven during diagnostic
checks.
T Sw: This monitors the state of the Throttle Switch. With the pedal in the idle
position the display should read “OFF”, when the pedal is pressed the display
should change to “ON”. If “OFF” is always displayed there is a problem with the
switch on the throttle pedal. This test can be performed in “Neutral” or with
either direction selected.
TPV: This is the raw Throttle pot voltage. This test should be performed with the
car in “Neutral”. 0.2 volts is normal for idle position, at full throttle, 3.5 volts for 2
wire pots, and 5.0 volts for 3 wire pots.
T Max: This is what the Max Throttle Voltage Parameter is set at. For example: If
the Parameter is set at 4.5, then the TPV will need to reach 4.5 for full speed to be
obtained. Use the Throttle calibration procedure if adjustments are necessary.
Req %: This is the amount of throttle being requested of the controller. This
should be a number from 0 to 100% when the car is being driven.
Brk: On or Off. Checks to ensure brake switch signal input to the controller.
Should be ON when the brake pedal is pressed and OFF when the brake pedal is
released.
Page 9 of 20
CapV: This is the voltage on the Capacitor Bank inside the controller. This voltage
should be at or near the voltage of the Batteries. When the Throttle is pressed,
this sends a signal to the controller to pre-charge the Capacitor Bank and turn the
Main Solenoid ON. If this voltage is low or at 0, this means there is probably a
failure in the Pre-Charge circuit and the controller will need to be repaired or
replaced.
EncA & EncB: These are the Motor Encoder signals shown in RPM. This can be
used to troubleshoot either an Encoder failure, or a problem in the Encoder
wiring. If the motor turns slow and in the proper direction, check the RPM of both
signals. If EncA has no signal, the Display will read Zero. The same applies to EncB.
EncA involves with White, (sometimes Brown), wire on the encoder connector,
EncB is the Green wire. On an EZGO, these colors are reversed.
Main: This is the state of the Main Contactor, see table below:
0 = Open, Solenoid not turned on.
1 = Pre-charge.
2 = Weld check, the controller is checking for welded contacts.
3 = Closing Delay
5 = Closed, the Solenoid coil is energized and the contacts should be closed.
6 = Open Delay, after the cart is stopped there is a delay of about 5 seconds for
the Solenoid to open.
OS: This is the Version of the Operating System in the controller.
Build: This is the Build number of the Operating System.
Ver: This is the VCL (vehicle control language) version number.
D/C: This is the date when the controller was manufactured. 6123=the 123rd day
of 2006
Page 10 of 20
S/N: This is the unique serial number of the controller.
Faults: If any, will be displayed.
Fault Codes
Fault codes will display on the Dash Display when they happen, the “Wrench” on
the display will also light up.
Code 12, Controller Over Current
Code 13, Current sensor fault
Code 14, Precharge Failure
Code 16, Controller Over Temperature
Code 17, Severe Undervoltage
