rate & G sensor.
2CHECK THE VDCCM&H/U.
1) Connect all the connectors.
2) Erase the memory.
3) Perform the inspection mode.
4) Read the DTC.
Is the same DTC displayed? Replace the
VDCCM&H/U.
Go to step 3.
3CHECK OTHER DTC DETECTION.Is any other DTC displayed? Perform the diag-
nosis according to
DTC.
Te m p o r a r y p o o r
contact occurs.
Step Check Yes No
1CHECK YAW RATE & G SENSOR INSTAL-
LATION.
Check the yaw rate & G sensor installation.
Are the yaw rate & G sensor
and bracket tightened to a
torque of 7.5 N·m (0.76 kgf-m,
5.5 ft-lb)?
Go to step 2.Tighten the yaw
rate & G sensor.
2CHECK G SENSOR OUTPUT.
1) Connect the Subaru Select Monitor to the
vehicle.
2) Select {Current Data Display & Save} in
Subaru Select Monitor.
3) Read the G sensor output displayed on
screen.
Is the value on the monitor dis-
play –1.5 — 1.5 m/s2?
Go to step 3.Replace the yaw
rate & G sensor.
3CHECK THE VDCCM&H/U.
1) Connect all the connectors.
2) Erase the memory.
3) Perform the inspection mode.
4) Read the DTC.
Is the same DTC displayed? Replace the
VDCCM&H/U.
Go to step 4.
4CHECK OTHER DTC DETECTION.Is any other DTC displayed? Perform the diag-
nosis according to
DTC.

DTC DETECTING CONDITION:
Defective G sensor
TROUBLE SYMPTOM:
VDC does not operate.
Step Check Yes No
1CHECK THE YAW RATE & G SENSOR POW-
ER SUPPLY.
1) Turn the ignition switch to OFF.
2) Disconnect the connector from yaw rate &
G sensor.
3) Turn the ignition switch to ON.
4) Measure the voltage between yaw rate & G
sensor and chassis ground.
Connector & terminal
(B359) No. 5 (+) — Chassis ground (–):
Is the voltage 10 — 15 V? Go to step 2.Replace the yaw
rate & G sensor
power supply cir-
cuit.
2CHECK GROUND CIRCUIT OF YAW RATE &
G SENSOR.
1) Turn the ignition switch to OFF.
2) Measure the resistance between the yaw
rate & G sensor and chassis ground.
Connector & terminal
(B359) No. 1 (+) — Chassis ground (–):
Is the resistance less than 0.5
Ω?
Go to step 3.Replace the yaw
rate & G sensor
power supply cir-
cuit.
3CHECK YAW RATE & G SENSOR.
1) Connect all the connectors.
2) Erase the memory.
3) Perform the inspection mode.
4) Read the DTC.
Is the same DTC displayed? Replace the
VDCCM&H/U.
Go to step 4.
4CHECK OTHER DTC DETECTION.Is any other DTC displayed? Perform the diag-
nosis according to

2CHECK G SENSOR OUTPUT.
1) Connect the Subaru Select Monitor to the
vehicle.
2) Select {Current Data Display & Save} in
Subaru Select Monitor.
3) Drive at a constant speed of approximately
40 km/h (25 MPH) and read the G sensor out-
put at that time.
Is the indicated reading on the
monitor display –1.5 — 1.5 m/
s2?
Go to step 3.Replace the yaw
rate & G sensor.
3CHECK THE VDCCM&H/U.
1) Connect all the connectors.
2) Erase the memory.
3) Perform the inspection mode.
4) Read the DTC.
Is the same DTC displayed? Replace the
