Is a Subaru Select Monitor available?

2.CHECK G SENSOR.

1) Turn the ignition switch to OFF.

2) Remove the G sensor from vehicle.

3) Connect the connector to G sensor.

4) Turn the ignition switch to ON.

5) Measure the voltage between G sensor connector terminals.

Connector & terminal

(B292) No. 2 (+) — No. 3 (−):

Is the voltage 2.3±0.2 V when G sensor is in a horizontal position?

Replace the G sensor.

3.CHECK G SENSOR.

Measure the voltage between G sensor connector terminals.

Connector & terminal

(B292) No. 2 (+) — No. 3 (−):

Is the voltage between 3.9±0.2 V when G sensor is inclined forward 90°?

Replace the G sensor.

4.CHECK G SENSOR.

Measure the voltage between G sensor connector terminals.

Connector & terminal

(B292) No. 2 (+) — No. 3 (−)

Is the voltage 0.7±0.2 V when the G sensor is inclined backward 90°?

G sensor is normal.

Replace the G sensor.

5.CHECK G SENSOR.

1) Turn the ignition switch to OFF.

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

3) Set the Subaru Select Monitor to the “BRAKE CONTROL” mode.

4) Set the display in the {Current Data Display & Save} mode.

5) Read the G sensor output value.

Is the value −1.2 — +1.2 m/s2 when the vehicle is in horizontal position?

Replace the G sensor.

6.CHECK G SENSOR.

1) Remove the console box.

2) Remove the G sensor from vehicle. (Do not disconnect the connector.)

3) Read the Subaru Select Monitor display.

When the G sensor is inclined forward 90°, is the value between 8.1 to 11.2 m/s2 ?

Replace the G sensor.

7.CHECK G SENSOR.

Read the Subaru Select Monitor display.

When the G sensor is inclined backward by 90°, is the value between −8.1 to −11.2 m/s2 ?

G sensor is normal.

Replace the G sensor.
