1. YAW RATE & G SENSOR SIGNAL

STEPCHECKYESNO

1.CHECK YAW RATE & G SENSOR.

1) Turn the ignition switch to OFF.

2) Connect the Subaru Select Monitor connector to the data link connector.

3) Turn the ignition switch to ON.

4) Set the Subaru Select Monitor connector to the {Brake Control System} mode.

5) Select {Current Data Display & Save}.

6) Read the output of yaw rate & G sensor.

Are the indicated values when the vehicle is placed horizontally, Lateral G sensor: −1.5 — 1.5 m/s2, Yaw rate sensor: −4 — 4 deg/s?

Repair the harness connector between yaw rate & G sensor and VDCCM&H/U. Or replace yaw rate & G sensor.

2.CHECK VEHICLE.

Is the vehicle AT model?

3.CHECK G SENSOR.

1) Remove the console box.

2) Remove the yaw rate & G sensor from vehicle without disconnecting the connector.

3) Read the display of Subaru Select Monitor.

NOTE:

When the yaw rate & G sensor is moved with its power supply on, DTC of yaw rate & G sensor may be recorded.

Is the value 6.8 — 12.8 m/s2 when the yaw rate & G sensor is inclined 90° to the forward?

Repair the harness connector between yaw rate & G sensor and VDCCM&H/U. Or replace yaw rate & G sensor.

4.CHECK G SENSOR.

Read the display of Subaru Select Monitor.

NOTE:

When the yaw rate & G sensor is moved with its power supply on, DTC of yaw rate & G sensor may be recorded.

Is the value −6.8 — −12.8 m/s2 when the yaw rate & G sensor is inclined 90° to the rearward?

Repair the harness connector between yaw rate & G sensor and VDCCM&H/U. Or replace yaw rate & G sensor.

5.CHECK G SENSOR.

1) Remove the console box. (AT model only)

2) Remove the yaw rate & G sensor from vehicle without disconnecting the connector. (AT model only)

3) Read the display of Subaru Select Monitor.

NOTE:

When the yaw rate & G sensor is moved with its power supply on, DTC of yaw rate & G sensor may be recorded.

Is the value 6.8 — 12.8 m/s2 when the yaw rate & G sensor is inclined 90° to the right?

Repair the harness connector between yaw rate & G sensor and VDCCM&H/U. Or replace yaw rate & G sensor.

6.CHECK G SENSOR.

Read the display of Subaru Select Monitor.

NOTE:

When the yaw rate & G sensor is moved with its power supply on, DTC of yaw rate & G sensor may be recorded.

Is the value −6.8 — −12.8 m/s2 when the yaw rate & G sensor is inclined 90° to the left?

Yaw rate & G sensors are normal.

Repair the harness connector between yaw rate & G sensor and VDCCM&H/U. Or replace yaw rate & G sensor.
