Diagnostic Procedure with Diagnostic Trouble Code (DTC)
10
CHECK YAW RATE & LATERAL G SENSOR.
1) Turn the ignition switch to OFF.
2) Connect all the connectors.
3) Turn the ignition switch to ON.
4) Measure the voltage between VDCCM&H/
U connector terminals.
Connector & terminal
(B310) No. 1 (+) — No. 16 (
−
):
Is the voltage 2.1 — 2.9 V?
Go to step 11.
Replace the yaw
rate & lateral G
sensor.
11
CHECK YAW RATE & LATERAL G SENSOR.
1) Turn the ignition switch to ON.
2) Check the signal pattern of oscilloscope
between VDCCM&H/U connector terminals.

SUREMENT, Control Module I/O Signal.>
Connector & terminal
(B310) No. 2 — No. 16:
(B310) No. 28 — No. 16:
Is the oscilloscope pattern the
same waveform as shown in
the figure?
Go to step 12.
Replace the yaw
rate & lateral G
sensor.
12
CHECK YAW RATE & LATERAL G SENSOR.
1) Turn the ignition switch to OFF.
2) Connect all the connectors.
3) Perform the clear memory mode.
4) Perform the inspection mode.
5) Read the DTC.
Is the same DTC displayed?
Go to step 13.
Go to step 15.
13
CHECK VDCCM&H/U.
1) Turn the ignition switch to OFF.
2) Replace the yaw rate & lateral G sensor.
3) Perform the clear memory mode.
4) Perform the inspection mode.
5) Read the DTC.
Is the same DTC displayed?
Replace the
VDCCM&H/U.
<Ref. to VDC-7,
VDC Control Mod-
ule and Hydraulic
Control Unit
(VDCCM&H/U).>
Go to step 16.
14
CHECK YAW RATE & LATERAL G SENSOR.
1) Turn the ignition switch to OFF.
2) Connect all the connectors.
3) Perform the clear memory mode.
4) Perform the inspection mode.
5) Read the DTC.
Is the same DTC displayed?
Replace the
VDCCM&H/U.
<Ref. to VDC-7,
VDC Control Mod-
ule and Hydraulic
Control Unit
(VDCCM&H/U).>
Go to step 15.
15
CHECK OTHER DTC DETECTION.
Is any other DTC displayed?
Perform the diag-
nosis according to
DTC.
Temporary poor
contact occurs.
16
CHECK OTHER DTC DETECTION.
Is any other DTC displayed?
Perform the diag-
nosis according to
DTC.
Malfunction is
found in original
yaw rate & lateral
G sensor.
