G Sensor: Inspection

DIAGNOSIS PROCEDURE CHART

Step	Check	Yes	No
1 CHECK SUBARU SELECT MONITOR.	Is a Subaru Select Monitor available?	Go to step 5 .	Go to step 2 .
2 CHECK G SENSOR. Turn the ignition switch to OFF. Remove the G sensor from vehicle. Connect the connector to G sensor. Turn the ignition switch to ON. 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?	Go to step 3 .	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 3.9 ± 0.2 V when the G sensor is inclined forward by 90°?	Go to step 4 .	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 by 90°?	G sensor is normal.	Replace the G sensor.
5 CHECK G SENSOR. Turn the ignition switch to OFF. Connect the Subaru Select Monitor to the data link connector. Set the Subaru Select Monitor to the {Brake Control} mode. Set the display in the {Current Data Display & Save} mode. Read the G sensor output.	Is the value -1.2 - 1.2 m/s when the vehicle is in a horizontal position?	Go to step 6 .	Replace the G sensor.
6 CHECK G SENSOR. Remove the console box. Remove the G sensor from vehicle. (Do not disconnect the connector.) Read the Subaru Select Monitor display.	Is the value 8.1 - 11.2 m/s when G sensor is inclined forward to 90°?	Go to step 7 .	Replace the G sensor.
7 CHECK G SENSOR. Read the Subaru Select Monitor display.	Is the value -8.1 - -11.2 m/s when G sensor is inclined backward 90°?	G sensor is normal.	Replace the G sensor.
