T: Display - Toro Workman GTX Electric & Lithium Service Manual

T: Display

The display is a LCD device located on the dash board.
The display provides the information about battery state
of charge, key on hours, eco mode, headlights On, fault
information and direction indication (F/N/R). Power for
the display is available when the key switch is in the ON
position. A 2 Amps fuse protects the all of the key
switched circuits.
The display communicates with the other machine con-
trollers on a Controller Area Network (CAN) bus system.
The machine electrical schematic and wire harness
drawings in Chapter 6 -- Electrical Drawings can be used
to identify possible circuit problems between the display
and the input or output devices.
IMPORTANT: When testing for wire harness con-
tinuity at the connector for the display, take care to
not damage the connector pins with multimeter test
leads. If connector pins are enlarged or damaged
during testing, connector repair may be necessary
for proper machine operation.
A 16 pin wire harness connector is attached to the dis-
play. The connection terminal function for the display
and the wire harness connector pins are shown Fig .
Check the display module and the harness connector
for damage or corrosion and clean or repair if necessary.

Because of the solid state circuitry built into the display,
there is no method to test the display directly. The dis-
play may be damaged if an attempt is made to test it with
an electrical test device (e.g. digital multimeter or test
light).
Note: If the display is replaced for any reason, system
software needs to be reloaded (contact an Authorized
Toro Distributor for assistance).
