Workman GTX Electric Lithium
Cause
Exceeded the maximum
motor speed.
The accelerator pedal is
pressed while starting the
machine.
Accelerator pedal operation
is abnormal.
The remaining charge on the
batteries is low (vehicle
speed has been limited by
controller).
The batteries are fully
discharged (vehicle does not
operate).
The internal capacitor has a
pre--charge of less than 5V.
The controller or traction
motor is overheated or too
cold.
A controller configuration
fault occurred.

Necessary Action
Turn key switch OFF, wait several seconds and
turn key switch ON. If controller does not reset
correctly, inspect traction motor encoder (speed
sensor) (see Traction Motor in this section).
Inspect the circuit wires between the traction
motor encoder and the controller (see Electrical
Schematic and Wire Harness Drawings in
Chapter 6 -- Electrical Drawings).
Release the accelerator pedal, turn the key
switch to the OFF position, wait several
seconds, turn the key switch to the ON position
and check for normal vehicle operation.
If controller does not reset correctly, check
accelerator pedal operation (see Accelerator
Pedal in this section).
Also, if necessary, inspect the circuit wires
between the accelerator pedal and the controller
(see Electrical Schematic and Wire Harness
Drawings in Chapter 6 -- Electrical Drawings).
Charge the batteries fully and then check for
normal operation.
If this fault occurs regularly, consider that battery
charging has not been regular or that batteries
may need replacement.
The vehicle may continue to operate but at
reduced power until the component temperature
reaches normal levels.
Determine if the motor or controller is very hot or
very cold, then allow the machine to return to
normal temperatures before resuming operation.
Make sure that motor and controller are cleaned
of all dirt and debris that could lead to
component overheating.
Turn the key switch to the OFF position, wait
several seconds, turn the key switch to the ON
position, and check for normal vehicle operation.
If this fault continues to occur, contact your
Authorized Toro Distributor for assistance.
