When diagnosis code No.51 is displayed
IExplanation]
When
the ignition switch
is
turned ON,
the
ABS
ECU
switches the valve relay
OFF and
ON for
an
initial check, compares the voltage of the
signal
to
the valve relay and valve power monitor line voltage
to
check whether
the
valve relay operation
is
normal.
In
addition, normally it monitors whether
orl
not there is power in the valve power monitor
line
since
the valve
relay
is
normally ON. Then,
if
the
supply
of power to the
valve power monitor line
is
interrupted,
this
trouble code
will
output.
