6) Read the output voltage of yaw rate & lat-
eral G sensor.
2 CHECK LATERAL G SENSOR.
1) Remove the console box.
2) Remove the yaw rate & lateral G sensor
from vehicle. (Do not disconnect the connec-
tor.)
3) Read the display of Subaru Select Monitor.

Yaw Rate & Lateral G Sensor
Are the indicated values when
the vehicle is placed horizon-
tally
Lateral G sensor: $1.5 — 1.5
m/s
Yaw rate sensor: $4 — 4 deg/
s?
Is the value 6.8 — 12.8 m/s
when the yaw rate & lateral G
sensor are inclined rightward
to 90%?
Is the value $6.8 — $12.8 m/s
when the yaw rate & lateral G
sensor are inclined leftward to
90%?
