C: INSPECTION
1. LATERAL G SENSOR SIGNAL
1 CHECK SUBARU SELECT MONITOR.
2 CHECK YAW RATE AND LATERAL G SEN-
SOR.
1) Move the vehicle to a flat location.
2) Turn ignition switch to OFF.
3) Connect connector to yaw rate and lateral
G sensor.
4) Turn ignition switch to ON.
5) Measure voltage between yaw rate and lat-
eral G sensor connector terminals.
Connector & terminal
(R100) No. 5 (+) — No. 6 ( − − − − )
Is the voltage within the specified range
when yaw rate and lateral G sensor is hori-
zontal?
3 CHECK YAW RATE AND LATERAL G SEN-
SOR.
1) Remove yaw rate and lateral G sensor from
vehicle.
2) Measure voltage between yaw rate and lat-
eral G sensor connector terminals.
Connector & terminal
(R100) No. 5 (+) — No. 6 ( − − − − )
NOTE:
If the yaw rate and lateral G sensor is moved,
the VDC (Yaw rate sensor) may be stored into
the memory.
Is the voltage within the specified range
when yaw rate and lateral G sensor is
inclined right to 90°?
4 CHECK YAW RATE AND LATERAL G SEN-
SOR.
Measure voltage between yaw rate and lateral
G sensor connector terminals.
Connector & terminal
(R100) No. 5 (+) — No. 6 ( − − − − )
NOTE:
If the yaw rate and lateral G sensor is moved,
the VDC (Yaw rate sensor) may be stored into
the memory.
Is the voltage within the specified range when
yaw rate and lateral G sensor is inclined left to
90°?
