PROBLEM SYMPTOM TABLE - G SENSOR

NO.	STEP	CHECK	YES	NO
1	CHECK SUBARU SELECT MONITOR	Do you have SUBARU SELECT MONITOR?	Go to step 5	Go to step 2
2	CHECK G SENSOR Turn ignition switch to OFF Remove G sensor from vehicle Connect connector to G sensor Turn ignition switch to ON Measure voltage between G sensor connector terminals	Is the voltage 2.3±0.2 V when G sensor is horizontal?	Go to step 3	Replace G sensor
3	CHECK G SENSOR Measure voltage between G sensor connector terminals. Connector & terminal: (R70) No.2 (+) - No.3 (-)	Is the voltage 3.9±0.2 V when G sensor is inclined forwards to 90°?	Go to step 4	Replace G sensor
4	CHECK G SENSOR Measure voltage between G sensor connector terminals. Connector & terminal: (R70) No.2 (+) - No.3 (-)	Is the voltage 0.7±0.2 V when G sensor is inclined backwards to 90°?	G sensor is normal	G sensor is normal
5	CHECK G SENSOR Turn ignition switch to OFF Connect select monitor connector to data link connector Turn select monitor into (BRAKE CONTROL) mode Set the display in the (Current Data Display & Save) mode. Read the G sensor output voltage	Is the indicated reading 2.3±0.2 V when the vehicle is in horizontal position?	Go to step 6	Replace G sensor
6	CHECK G SENSOR Remove console box Remove G sensor from vehicle. (Do not disconnect connector0 Read the select monitor display	Is the indicated reading 3.9±0.2 V when the vehicle is inclined forwards to 90°?	Go to step 7	Replace G sensor
7	CHECK G SENSOR Read the select monitor display	Is the indicated reading 0.7±0.2 V when the G sensor is inclined backwards to 90°?	G sensor is normal	Replace G sensor
