1CHECK IGNITION SWITCH.Is the ignition switch ON? Go to step 2.Turn the ignition
switch to ON, and
select VDC mode
using Subaru
Select Monitor.
2CHECK BATTERY.
1) Turn the ignition switch to OFF.
2) Measure the battery voltage.
Is the voltage more than 11 V? Go to step 3.Charge or replace
the battery.
3CHECK BATTERY TERMINAL.Is there poor contact at battery
terminal?
Repair or tighten
the battery termi-
nal.
Go to step 4.
4CHECK SUBARU SELECT MONITOR COM-
MUNICATION.
1) Turn the ignition switch to ON.
2) Using the Subaru Select Monitor, check
whether communication to other system can
be executed normally.
Are the system name and
model year displayed on Sub-
aru Select Monitor?
Go to step 8.Go to step 5.
5CHECK SUBARU SELECT MONITOR COM-
MUNICATION.
1) Turn the ignition switch to OFF.
2) Disconnect the VDCCM&H/U connector.
3) Turn the ignition switch to ON.
4) Check whether communication to other
systems can be executed normally.
Are the system name and
model year displayed on Sub-
aru Select Monitor?
Replace the
VDCCM&H/U.

Go to step 6.
6CHECK HARNESS CONNECTOR BETWEEN
EACH CONTROL MODULE AND DATA LINK
CONNECTOR.
1) Turn the ignition switch to OFF.
2) Disconnect the VDCCM&H/U, ECM and
TCM.
3) Measure the resistance between data link
connector and chassis ground.
Connector & terminal
(B402) No. 10 — Chassis ground:
Is the resistance more than 1
MΩ?
Go to step 7.Repair the har-
ness and connec-
tor between each
control module
and data link con-
nector.
7CHECK THE VDCCM&H/U OUTPUT SIG-
NALS.
1) Turn the ignition switch to ON.
2) Measure the voltage between data link con-
nector and chassis ground.
Connector & terminal
(B402) No. 10 (+) — Chassis ground (–):
Is the voltage less than 1 V? Go to step 8.Repair the har-
ness and connec-
tor between each
control module
and data link con-
nector.
8CHECK THE HARNESS CONNECTOR BE-
TWEEN VDCCM&H/U AND DATA LINK CON-
NECTOR.
Measure the resistance between VDCCM&H/U
connector and data link connector.
Connector & terminal
(B310) No. 32 — (B402) No. 10:
Is the resistance less than 0.5
Ω?
Go to step 9.Repair harness
and connector
between
VDCCM&H/U and
data link connec-
tor.
9CHECK INSTALLATION OF VDCCM&H/U
CONNECTOR.
Tu r n t h e i g n i t i o n s w i t c h t o O F F.
Is the VDCCM&H/U connector
inserted into VDCCM&H/U
until the clamp locks onto it?
Go to step 10.Insert VDCCM&H/
U connector into
VDCCM&H/U.
10 CHECK POWER SUPPLY CIRCUIT.
1) Turn the ignition switch to ON.(Engine OFF)
2) Measure the ignition power supply voltage
between VDCCM&H/U connector and chassis
ground.
Connector & terminal
(B310) No. 1 (+) — Chassis ground (–):
Is the voltage 10 — 15 V? Go to step 11.Repair open circuit
in harness
between
VDCCM&H/U and
battery.
