Description
T6 There is a
problem with
control of the
48V main
contactor –
the contactor
is closed when it
should be open.
T6 The minimum
precharge
voltage (38V)
was not
achieved in
the appropriate
time.
SC8 A Li-ion battery
cell voltage was
measured to be
low, but is still
recoverable.
SC8 A Li-ion battery
cell voltage was
measured to be
high.
Additional Notes Service Actions
PTO, 1.
starter/generator,
and lift/lower is
disabled.

PTO, Start with a component that may have just
starter/generator, blown a fuse and disconnect one cutting
and lift/lower is unit motor or lift/lower actuator at a time
disabled. until the fault stops repeating.

Check the voltage across the coil of
the main contactor with the key Off.
It should be 0V when the contactor is
open.
Check the voltage across the contactor
with the key Off. It should be 48V
when the contactor is open.
Test the main contactor.
The starter/generator must remain
connected because it reports this fault.
If one of the cutting unit motors or
lift/lower actuators is reporting a
COMM fault, that is likely the shorted
component.
Charge the batteries. The contactor
in Li-ion battery controller should be
allowed to close once the battery
voltage reaches 42V.
Test the battery pack voltage at the
Li-ion battery controller B+ and B-
terminals.
• If the battery pack voltage is above
21V, reprogram the Li-ion battery
controller or replace the controller if
necessary (contact an Authorized
Toro Distributor for assistance).
• If the battery pack voltage is below
21V, replace the batteries.
If the fault occurred with a full Li-ion
battery during a regenerative charge
(coasting – traction motors charging
battery), everything is likely fine. Cycle
the key switch and continue operation.
If the fault occurred when the Li-ion
battery state of charge is less than
90%, forward a copy of the battery
output file (.BDS) to Toro Service
(contact an Authorized Toro Distributor
for assistance).
