B
I
ABS warning lamp illuminated after the engine is started and remains
on.
lExplanationl
This is the symptom when the ABS
ECU does not
power up due
to
broken ECU
power circuit.
etc.,
when the fail safe function
operates
and
isolates
the
system
or when the warning lamp drive circuit
is short circuited.
IHintl
Check the diagnosis output and if there is no output
voltage
or
if
the
MUT and ABS
ECU
cannot
communicate, there
is a good possibility that power
is not
flowing
to the
ECU.
Caution
.
lf there is no output of trouble
codes, there
is a
good possibility that the
fail
safe
is
functioning.
