wave devices and
electric compo-
nents properly.
5CHECK CAUSE OF SIGNAL NOISE.

sources apart from
sensor harness.
Go to step 6.
6CHECK THE VDCCM&H/U.

Go to step 7.
7CHECK OTHER DTC DETECTION.Is any other DTC displayed? Perform the diag-
nosis according to
DTC.
It results from a
temporary noise
interference.
8CHECK INSTALLATION OF ABS WHEEL
SPEED SENSOR.
Is the ABS wheel speed sen-
sor installation bolt tightened
7.5 N·m (0.76 kgf-m, 5.5 ft-lb)?
Go to step 9.Tighten the ABS
wheel speed sen-
sor installation
bolts.
9CHECK ABS WHEEL SPEED SENSOR SIG-
NAL.
1) Install the ABS wheel speed sensor.
2) Prepare an oscilloscope.
3) Check the ABS wheel speed sensor. to VDC-22, ABS WHEEL SPEED SENSOR,
INSPECTION, Front ABS Wheel Speed Sen-
sor.>
Does the oscilloscope indicate
the waveform pattern like
shown in the figure when the
tire is slowly turned? Does the
oscilloscope indication repeat
the waveform pattern like
shown in the figure when the
tire is slowly turned in equal
speed for more one rotation?
Go to step 11.Go to step 10.

interference.
NOTE:
Though the ABS
warning light re-
mains on at this
time, it is normal.
Drive the vehicle at
more than 12 km/h
(7 MPH) in order to
turn ABS warning
light off. Be sure to
drive the vehicle
and check the
warning light goes
off.
