1
CHECK YAW RATE & LATERAL G SENSOR.
1) Turn the ignition switch to OFF.
2) Connect the Subaru Select Monitor con-
nector to data link connector.
3) Turn the ignition switch to ON.
4) Set the Subaru Select Monitor connector to
the {Brake Control} mode.
5) Select {Current Data Display & Save}.
6) Read the output voltage of yaw rate & lat-
eral 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?
Go to step 2.
Repair the har-
ness connector
between yaw rate
& lateral G sensor
and VDCCM&H/U.
Or replace the yaw
rate & lateral 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.
NOTE:
When the yaw rate & lateral G sensor is moved
with its power supply on, DTC of yaw rate & lat-
eral G sensor may be recorded.
Is the value 6.8 — 12.8 m/s
when the yaw rate & lateral G
sensor are inclined rightward
to 90
°
?
Go to step 3.
Repair the har-
ness connector
between yaw rate
& lateral G sensor
and VDCCM&H/U.
Or replace the yaw
rate & lateral G
sensor.
3
CHECK LATERAL G SENSOR.
Read the display of Subaru Select Monitor.
NOTE:
When the yaw rate & lateral G sensor is moved
with its power supply on, DTC of yaw rate & lat-
eral G sensor may be recorded.
Is the value
−
6.8 —
−
12.8 m/s
when the yaw rate & lateral G
sensor are inclined leftward to
90
°
?
Yaw rate & lateral
G sensor is nor-
mal.
Repair the har-
ness connector
between yaw rate
& lateral G sensor
and VDCCM&H/U.
Or replace the yaw
rate & lateral G
sensor.
