[Explanation]
The ABS ECU normally monitors the solenoid valve
drive circuit.
If no current flows in the solenoid even if the ECU
turns the solenoid ON or if it continues to flow even

SOLENOID
ABS ECU
when turned OFF, the ECU determines the solenoid
coil wire is broken/short-circuited or the harness
is broken/short-circuited, and then these diagnostic
trouble codes are output.
Is the resistance
solenoid valve within the ranae
of the standard values?
Standard value: 1.0-l .3 Q

Is the solenoid valve resis-
tance value within the range of
the standard values when
measured at the ECU connec-

Standard value: 1.0-l .3Q
Yes

Revision
Replace HU.
The harness wire for the
solenoid valve circuit
whose resistance value is
outside the range of the
standard value is broken
or short circuited.
