Affected
Fault Title
P0AC2 Battery --
Over Current
SC1 Abatteryis
supplying too much
current for t oo long.
This can either be
because of too much
powerdrawora
battery cell
imbalance.
Discharge current is
greater than 130A
for 30s
OR
greater than
178.75A for 6s.
Battery contactor is
opened.
1) Reduce power draw.
2) Check battery and
machine harness for
damaged wires.
3) Battery likely damaged.
Contact an Authorized Toro
Distributor for assistance.
P0AFA Battery -- Low
Voltage
SC1 A battery voltage
was measured to be
lower than the
allowed threshold
but is still
recoverable.
Battery contactor is
opened and BMS is
offline.
Contact Toro TAC to recover
the battery.
P0AFB Battery -- High
Voltage
SC1 A battery voltage
was measured to be
higher than the
allowed threshold.
Battery contactor is
opened.
1) If the fault occurred with a
full battery during a
regenerative braking,
everything is likely fine.
2) If the fault occurred when
the state of charge is less
than 90%. Contact an
Authorized Toro Distributor
for assistance.
P0E8E Traction Motor
Bus Voltage --
Low
SC2 The motor bus
voltage is lower than
the low voltage
threshold.
Bus voltage is below
the voltage limits:
33V (Sevcon)
Traction is disabled.
1) Check the fuse.
2) Measure the voltage at the
motor connector to determine
whether the voltage is low or
the controller is measuring
low.
3) Check the battery voltage.
4) Ensure the wiring is ok to
the motor.
P0E8F Traction Motor
Bus Voltage --
High
SC2 The motor bus
voltage exceeds the
high voltage
threshold.
Bus Voltage
exceeds 69V
(Sevcon).
Traction is disabled.
1) Measure the voltage at the
motor connector to determine
whether the voltage is high or
the controller is measuring
high.
2) Check the battery voltage.
3) Ensure the wiring is ok to
the motor.
