Is the resistance value of the wheel speed
sensor part, which the displayed diagnos- -

Check the output of each
wheel speed sensor with an
oscilloscope, including the
wave form. (Refer to mea-
surement of wheel speed
sensor output voltage varia-
tions on P.35-69.) Is the out-
put voltage for each wheel
speed sensor over the stand-
ard value and is the wave
form normal?
