VEHICLE DYNAMICS CONTROL (VDC) (DIAGNOSTICS)
Diagnostic Procedure with Diagnostic Trouble Code (DTC)
Step
Check
Yes
No
1
WHETHER A WHEEL TURNED FREELY OR
NOT.
Check if the wheels have been turned freely for
more than one minute, such as when the vehi-
cle is jacked-up, under full-lock cornering or
when the wheels are not in contact with road
surface.
Did the wheels turn freely?
VDC is normal.
Erase the memory.
NOTE:
When the wheels
turn freely for a
long time, such as
when the vehicle is
towed or jacked-
up, or when steer-
ing wheel is contin-
uously turned all
the way, this diag-
nostic trouble code
may sometimes
occur.
Go to step 2.
2
CHECK TIRE SPECIFICATIONS.
Turn the ignition switch to OFF.
Are the tire specifications cor-
rect?
Go to step 3.
Replace the tire.
3
CHECK WEAR OF TIRE.
Is the tire worn excessively?
Replace the tire.
Go to step 4.
4
CHECK TIRE INFLATION PRESSURE.
Is the tire pressure correct?
Go to step 5.
Adjust the tire
pressure.
5
CHECK INSTALLATION OF ABS WHEEL
SPEED SENSOR.
Are the ABS wheel speed sen-
sor installation bolts tightened
to 7.5 N
⋅
m (0.76 kgf-m, 5.5 ft-
lb)? (For four wheels)
Go to step 6.
Tighten the ABS
wheel speed sen-
sor installation
bolts.
6
CHECK ABS WHEEL SPEED SENSOR SIG-
NAL.
1) Install the ABS wheel speed sensor.
2) Prepare an oscilloscope.
3) Check the ABS wheel speed sensor. <Ref.
to ABS-13, ABS WHEEL SPEED SENSOR,
INSPECTION, Front ABS Wheel Speed Sen-
sor.>
Is the oscilloscope pattern the
same waveform as shown in
the figure when the tire is
rotated? Is the pattern as
shown in the figure displayed
regularly in the oscilloscope
when the tire is slowly rotated
more than one revolution with
even speed?
Go to step 8.
Go to step 7.
7
CHECK ABS WHEEL SPEED SENSOR OR
MAGNETIC ENCODER.
Are there foreign materials,
breakage or damage in the
protrusion of ABS wheel speed
sensor or magnetic encoder?
Remove dirt thor-
oughly. Replace
the ABS wheel
speed sensor or
magnetic encoder
as a unit with hub
unit bearing if
there is breakage
or damage.
Go to step 8.
8
CHECK VDCCM&H/U.
1) Connect all the connectors.
2) Erase the memory.
3) Perform the inspection mode. <Ref. to
VDC(diag)-23, PROCEDURE, Inspection
Mode.>
4) Read the DTC.
Is the same DTC displayed?
Replace the
VDCCM&H/U.
<Ref. to VDC-7,
VDC Control Mod-
ule & Hydraulic
Control Unit
(VDCCM&H/U).>
Go to step 9.
