Diagnostic Procedure with Diagnostic Trouble Code (DTC)
LAN SYSTEM (DIAGNOSTICS)
Step Check Yes No
1CHECK IGNITION SWITCH.Is the ignition switch ON? Go to step 2.Turn the ignition
switch to ON, and
select Integ. Unit
mode using Sub-
aru 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 COMMUNICATION OF SUBARU SE-
LECT MONITOR.
1) Turn the ignition switch to ON.
2) Using the Subaru Select Monitor, check
whether communication to other systems can
be executed normally.
Are system and model year
displayed?
Go to step 7.Go to step 5.
5CHECK COMMUNICATION OF SUBARU SE-
LECT MONITOR.
1) Turn the ignition switch to OFF.
2) Disconnect the body integrated unit con-
nector.
3) Turn the ignition switch to ON.
4) Check whether communication to other
systems can be executed normally.
Are system and model year
displayed?
Go to step 7.Go to step 6.
6CHECK HARNESS CONNECTOR BETWEEN
EACH CONTROL UNIT AND SUBARU SE-
LECT MONITOR.
1) Turn the ignition switch to ON.
2) Disconnect the body integrated unit con-
nector.
3) Measure the resistance between data link
connector and chassis ground.
Connector & terminal
(B40) 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 unit and
Subaru Select
Monitor.
7CHECK OUTPUT SIGNAL TO BODY INTE-
GRATED UNIT.
1) Turn the ignition switch to ON.
2) Measure the voltage between body inte-
grated unit and chassis ground.
Connector & terminal
(B40) 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 unit and
Subaru Select
Monitor.
8CHECK HARNESS CONNECTOR BETWEEN
BODY INTEGRATED UNIT AND DATA LINK
CONNECTOR.
Measure the resistance between body inte-
grated unit and data link connector.
Connector & terminal
(B40) No. 10 — (B280) No. 19:
Is the resistance less than 1
Ω?
Go to step 9.Repair the har-
ness and connec-
tor between body
integrated unit and
Subaru Select
Monitor.
9CHECK INSTALLATION OF BODY INTE-
GRATED UNIT 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 body integrated unit con-
nector inserted into body inte-
grated unit until the clamp
locks onto it?
Go to step 10.Insert the body
integrated unit
connector into
body integrated
unit.

CAUTION:
When replacing body integrated unit on the model with immobilizer system, refer to the “REGISTRA-
TION MANUAL FOR IMMOBILIZER”.
10 CHECK POWER SUPPLY CIRCUIT.
1) Turn the ignition switch to ON (engine
OFF).
2) Measure the ignition voltage between body
integrated unit connector and chassis ground.
Connector & terminal
(i84) No. 1 (+) — Chassis ground (–):
Is the voltage more than 10 V? Go to step 11.Repair the open
circuit of harness
between body inte-
grated unit and
battery.
11 CHECK HARNESS CONNECTOR BETWEEN
BODY INTEGRATED UNIT AND CHASSIS
GROUND.
1) Turn the ignition switch to OFF.
2) Disconnect the connector from body inte-
grated unit.
3) Measure the resistance of harness
between the body integrated unit and chassis
ground.
Connector & terminal
(B280) No. 19 — Chassis ground:
Is the resistance more than 1
MΩ?
Go to step 12.Repair the poor
contact of har-
ness between
body integrated
unit and ground.
12 CHECK POOR CONTACT OF CONNEC-
TORS.
Is there poor contact at control
unit ground and Subaru Select
Monitor?
Repair the poor
contact of connec-
tor.
Replace the body
integrated unit.
