2
CHECK YAW RATE & G SENSOR GROUND
CIRCUIT.
Measure the resistance between yaw rate & G
sensor and chassis ground.
Connector & terminal
(B230) No. 4 — Chassis ground:
Is the resistance less than 0.5
:
? Go to step
3
.
Repair the yaw rate
& G sensor ground
circuit.
3
CHECK YAW RATE & G SENSOR HARNESS.
1) Disconnect the connector from the
VDCCM&H/U.
2) Measure the resistance between VDCCM&
H/U and yaw rate & G sensor.
Connector & terminal
(B230) No. 3 — (B310) No. 10:
(B230) No. 2 — (B310) No. 35:
Is the resistance less than 0.5
:
? Go to step
4
.
Repair the harness
between yaw rate
& G sensor and
VDCCM&H/U.
4
CHECK GROUND SHORT CIRCUIT IN YAW
RATE & G SENSOR HARNESS.
Measure the resistance between yaw rate & G
sensor and chassis ground.
Connector & terminal
(B230) No. 2 — Chassis ground:
(B230) No. 3 — Chassis ground:
Is the resistance 1 M
:
or
more?
Go to step
5
.
Repair the harness
between yaw rate
& G sensor and
VDCCM&H/U.
5
CHECK YAW RATE & G SENSOR.
1) Turn the ignition switch to OFF.
2) Connect all connectors.
3) Clear the memory. <Ref. to VDC(diag)-24,
Clear Memory Mode.>
4) Perform the Inspection Mode. <Ref. to
VDC(diag)-23, Inspection Mode.>
5) Read the DTC.
Is the same DTC displayed?
Go to step
6
.
Go to step
7
.
6
CHECK YAW RATE & G SENSOR.
1) Turn the ignition switch to OFF.
2) Replace the yaw rate & G sensor. <Ref. to
VDC-16, Yaw Rate and G Sensor.>
3) Clear the memory. <Ref. to VDC(diag)-24,
Clear Memory Mode.>
4) Perform the Inspection Mode. <Ref. to
VDC(diag)-23, Inspection Mode.>
5) Read the DTC.
Is the same DTC displayed?
Replace the
VDCCM only.
<Ref. to VDC-9,
REPLACEMENT,
VDC Control Mod-
ule and Hydraulic
Control Unit
(VDCCM&H/U).>
Go to step
8
.
7
CHECK OTHER DTC DETECTION.
Is any other DTC displayed?
Perform the diag-
nosis according to
DTC. <Ref. to
VDC(diag)-33, List
of Diagnostic Trou-
ble Code (DTC).>
Temporary poor
contact occurs.
8
CHECK OTHER DTC DETECTION.
Is any other DTC displayed?
Perform the diag-
nosis according to
DTC. <Ref. to
VDC(diag)-33, List
of Diagnostic Trou-
ble Code (DTC).>
Malfunction is
found in original
yaw rate & G sen-
sor.
