G Sensor: Inspection

DIAGNOSTIC 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 the G sensor. Turn the ignition switch 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 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°?	Go to step 4.	Replace 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 G sensor.
5 CHECK G SENSOR. Turn the ignition switch to OFF. Connect the Subaru Select Monitor to 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 voltage.	Is the indicated reading on the monitor display 0±0.1 m/s² ?	Go to step 6.	Replace 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 numerical value -9.8±0.1 m/s² when G sensor is inclined forward 90°?	Go to step 7.	Replace G sensor.
7 CHECK G SENSOR. Read the Subaru Select Monitor display.	Is the numerical value 9.8±0.1 m/s² when G sensor is inclined back 90°?	G sensor is normal.	Replace G sensor.
