10
Current
collection
fault
•
Current
collection
abnormalities.
•
Disconnected,
loose
or
misconnected
sampling wire.
•
CMU failure.
•
Check that the current sampling
wire is not disconnected.
11
Abnormal
voltage
collection
•
Broken
BMU
voltage
collection
cable.
•
Loose
voltage
collection
wire
terminal.
•
Check the BMU for damage and
replace it if it is damaged.
•
Check that the voltage sampling
cable is not disconnected.
12
Temperature
acquisition
anomaly
•
BMU temperature
sensing collection
line disconnected.
•
Loose temperature
sensing collection
wire terminal.
•
Check the BMU for damage and
replace it if it is damaged.
•
Check that the sampling line is not
dislodged.
•
Check
that
the
temperature
sensing has not failed.
13
CMU-BMU
communica-
tion failure
The communication
cable is disconnected
and the BMU is
damaged.
•
Check
that
the
communication
lines are connected properly and
that the communication lines are in
the correct sequence.
•
Check that the first slave that is not
communicating is not damaged
(the
communication
line
connection skips this module).
•
Check for damage to the CMU in
the DCDC.
14
CMU-BSC
communica-
tion failure
Communication cable
disconnected, BSC
damaged, CAN
matching resistor not
connected.
•
Check
that
the
communication
lines are connected properly.
•
Check that the CAN matching
resistor is installed.
•
Check for damage to the CMU in
the DCDC as well as to the
container BSC.
