Affected
Fault Title
P1A02 Battery
Charging--
Low Temp
Shutdown
SC1 Abattery
temperature was
measured to be less
than the allowed
threshold and will
not charge.
Oneormoreofthe
batteries temp is
less than --10 ºC.
Battery contactor is
opened.
Let the machine warm up
before operating.
P1A11 Battery
Charging
Voltage --
High
SC1 A battery voltage
was measured to be
higher than the
allowed threshold
while the battery
charger was
connected.
Battery contactor is
opened.
1) Check the charger for
faults.
2) Replace the charger.
P1A21 Battery
Charging --
Over Current
SC1 A battery charging
current was
measured to be
greater than the
allowed threshold.
This is likely due to
an internal
imbalance in one or
more of the
batteries.
Battery contactor is
opened.
1) Replace the charger.
2) Check battery and charger
harness for damaged wires.
3) Contact an Authorized
Toro Distributor for
assistance.
P2BE8 Traction Motor
Contactor --
Open
SC2 The contactor is
detected open when
it should be closed.
Both traction motors
measure a low bus
voltage when the
contactor should be
closed.
Traction is disabled.
1) Check voltage across the
coil of the contactor. Should
be approx. 48V if the
contactor is engaged.
2) Check the voltage across
thecontactor.Shouldbe0Vif
contactor is closed.
3) Test the contactor.
4) If this fault occurs
concurrently with a generator
under voltage fault or system
under voltage related fault,
check the key switch.
P2BE9 Traction Motor
Contactor --
Closed
SC2 The contactor is
detected closed
when it should be
open. It is likely
welded shut.
Traction is disabled. 1) Check the voltage across
the contactor with the key off.
Should be 48V.
2) Check voltage across the
coil of the contactor with Key
OFF. Should be 0V.
3) Test the contactor.
4) Replace contactor.
