1.CHECK DRIVING PLACE.
Check if the vehicle ran the road with banks or sandy surface (which does not mean a dirt road).
|
Did the vehicle run the road with banks or sandy surface (which does not mean a dirt road)?
|
VDCCM&H/U may record DTC when the vehicle ran the road with banks or sandy surface (which does not mean a dirt road).
|
|
2.CHECK YAW RATE & LATERAL G SENSOR INSTALLATION.
|
Is the yaw rate & lateral G sensor installation bolt tightened to 7.5 N·m (0.76 kgf-m, 5.5 ft-lb)?
|
|
Tighten the yaw rate & lateral G sensor installation bolt.
|
3.CHECK YAW RATE & LATERAL G SENSOR POWER SUPPLY.
1) Turn the ignition switch to OFF.
2) Disconnect the connector from yaw rate & lateral G sensor.
3) Turn the ignition switch to ON.
4) Measure the voltage between yaw rate & lateral G sensor and chassis ground.
Connector & terminal
(B230) No. 1 (+) — Chassis ground (−):
|
Is the voltage 10 — 15 V?
|
|
Repair the yaw rate & lateral G sensor power supply circuit.
|
4.CHECK YAW RATE & LATERAL G SENSOR GROUND CIRCUIT.
Measure the resistance between the yaw rate & lateral G sensor and chassis ground.
Connector & terminal
(B230) No. 4 — Chassis ground:
|
Is the resistance less than 0.5 Ω?
|
|
Repair the yaw rate & lateral G sensor ground circuit.
|
5.CHECK OUTPUT OF YAW RATE & LATERAL G SENSOR WITH SUBARU SELECT MONITOR.
1) Drive the vehicle on a flat road.
2) Park the vehicle straight.
3) Select {Current Data Display & Save} in Subaru Select Monitor.
4) Read the yaw rate output displayed on display.
|
Is the reading indicated on monitor display −4 — 4 deg/s?
|
|
Replace the yaw rate & lateral G sensor.
|
6.CHECK YAW RATE & LATERAL G SENSOR.
1) Turn the ignition switch to OFF.
2) Connect all connectors.
3) Clear the memory. 
4) Perform the Inspection Mode.
|
Is the same DTC displayed?
|
|
|
7.CHECK VDCCM&H/U.
1) Turn the ignition switch to OFF.
2) Replace the yaw rate & lateral G sensor.
3) Clear the memory.
4) Perform the Inspection Mode.
|
Is the same DTC displayed?
|
Replace the VDCCM only.
|
|
8.CHECK OTHER DTC DETECTION.
|
Is any other DTC displayed?
|
Perform the diagnosis according to DTC.
|
Temporary poor contact occurs.
|
9.CHECK OTHER DTC DETECTION.
|
Is any other DTC displayed?
|
Perform the diagnosis according to DTC.
|
Malfunction is found in original yaw rate & lateral G sensor.
