TRUCOURSE TECHNOLOGY
SYSTEM™
GENERAL
TruCourse Technology (TCT) system vehicles are oper-
ated in one of four modes or “performance options”. All
options have standard features that control, protect and
diagnose the vehicle. The options are defined as fol-
lows:
1. The Golf Coastal performance option: The motor’s
speed is sensed and regulated to a maximum of 14.8
mph (23.8 kph) and minimum of 10.2 mph (16.4 kph)
directly by the controller, the vehicle’s flat ground
speed will not change with different ground surfaces.
The speed sensor also allows for precise control of
the downhill vehicle speed during regenerative brak-
ing. As the vehicle crests a hill and begins to descend,
the speed will be smoothly regulated to 14.8 mph
(23.8 kph). This option is enabled when there is a
blank plug installed and by the handheld diagnostic
tool.
2. The Golf Steep Hill performance option: This option
includes all of the driving features of the Golf Coastal
performance option with the motor’s speed sensed
and regulated to 12.8 mph (20.6 kph) plus regenera-
tive braking. Regenerative braking occurs when the
throttle is released while the vehicle is moving. The
motor will electrically resist the motion of the vehicle
until the throttle is depressed again or the vehicle
stops. This is the strongest of the three compression
braking options. This option is enabled by the hand-
held diagnostic tool.
3. The Golf Mild Hill performance option: This option
includes all of the driving features of the Steep Hill
option with the motor’s speed sensed and regulated to
13.8 mph ( 22.2 kph ), except that the regenerative
braking feel is milder. This option is enabled by the
handheld diagnotic tool.
4. The Freedom performance option: This option
includes all of the driving features of the Golf Coastal
option except that the flat ground and downhill com-
pression braking speeds are 18.5 mph (29.7 kph)
instead of 13.2 mph (21 kph). This option is enabled
by the handheld diagnotic tool. THIS OPTION IS NOT
OFFERED ON FLEET VEHICLES.
Handheld can be used anytime as long as the Run-Tow
switch is not in the Tow position or when the battery
charger is connected to the vehicle.
Performance options of the TCT System include:
•
Anti-Roll back to limit backward motion of the
vehicle down an incline to less than 2 mph
(3 kph).
•
Walk-Away to limit vehicle movement without
driver input, slowing the vehicle to 2 mph (3 kph)
and sounding an audible alarm (reverse beeper)
•
Anti-Stall protection to prevent motor commutator
damage from stalling the vehicle against an
object or on a hill.
•
High pedal disable to prevent undesired accelera-
tion if the direction selector lever is changed, or
the key is turned on while the accelerator is
depressed.
•
Diagnostic mode by handheld only to ease trou-
bleshooting.

& DIAGNOSTICS
Changing Performance Options
The performance option may be changed if the existing
option is not compatible with the terrain that the vehicle
will be operated.
1. Raise the seat and ensure that the Run-Tow/Mainte-
nance switch is in the ‘RUN’ position.
2. Ensure that the charger is unplugged from the vehicle.
3. Locate the vehicle diagnostic port and remove the
environmental cover.
4. Connect the handheld diagnostic tool and select the
desired performance setting.
5. Disconnect the handheld diagnostic tool, replace the
environmental cover and seat.
