Diagnostic Procedure with Diagnostic Trouble Code (DTC)
Step
7 CHECK HARNESS BETWEEN DRIVER'S
CONTROL CENTER DIFFERENTIAL CON-
TROL MODULE AND YAW RATE & LATER-
AL G SENSOR.
Measure the resistance between the driver's
control center differential control module con-
nector and chassis ground.
Connector & terminal
(B380) No. 19 — Chassis ground:
8 CHECK LATERAL G SENSOR.
1) Turn the ignition switch to OFF.
2) Connect all the connectors.
3) Connect the Subaru Select Monitor to the
data link connector.
4) Turn the ignition switch and run the Subaru
Select Monitor.
Use the Subaru Select Monitor to read "yaw
rate & lateral G sensor reference" data. <Ref. to
6MT(diag)-16, READ CURRENT DATA, OPER-
ATION, Subaru Select Monitor.>
9 CHECK YAW RATE & LATERAL G SENSOR.
Measure the voltage between the driver's con-
trol center differential control module harness
connectors.
Connector & terminal
(B380) No. 19 (+) — No. 20 (–):

Check
Is the resistance 1 MΩ or
more?
Is the data 2.1 — 2.9V?
Is the voltage 2.1 — 2.9 V?
