Diagnostic Procedure with Diagnostic Trouble Code (DTC)
LAN SYSTEM (DIAGNOSTICS)
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.

B: DIAGNOSTIC TROUBLE CODE (DTC) IS NOT STORED
DIAGNOSIS:
Defective combination meter
TROUBLE SYMPTOM:
•Communication error display in odo/trip meter is not cleared.
•“No trouble code” is displayed on Subaru Select Monitor.
NOTE:
If DTC is not displayed on Subaru Select Monitor, LAN communication System should be OK.
C: DTC B0100 INTEG. UNIT SYSTEM ERROR
DTC DETECTING CONDITION:
System error in body integrated unit
TROUBLE SYMPTOM:
•Check light comes on in the combination meter, and displays communication error display “Er IU”.
•LAN communication immobilizer function may not be executed normally.
Step Check Yes No
1CHECK COMMUNICATION ERROR DIS-
PLAY WITH COMBINATION METER.
Tu r n t h e i g n i t i o n s w i t c h t o O N .
Is communication error dis-
played?
Inspect the DTC. Go to step 2.
2CHECK COMBINATION METER.
Perfor m the self-diagnosis of combination
meter.
Is combination meter OK? Go to step 3.Replace the com-
bination meter.

Meter.>
3CHECK THE BODY INTEGRATED UNIT.
1) Display the current data of ECM using Sub-
aru Select Monitor.
2) Check data of “body integrated unit data
received”.
Is “Yes” displayed? Go to step 4.Replace the body
integrated unit.
Body Integrated
Unit.>
4CHECK THE BODY INTEGRATED UNIT.
1) Display the current data of ECM using Sub-
aru Select Monitor.
2) Check data of “body Integrated unit counter
update”.
Is “Yes” displayed? Repair the poor
contact of connec-
tor.
Replace the body
integrated unit.

Unit.>
Step Check Yes No
1CHECK ALL DTCS.Is DTC concerning ECM dis-
played?
Go to step 2.Replace the body
integrated unit.

2CHECK DTC CONCERNING ECM.Is output DTC on ECM con-
cerning CAN communication
error?
Replace the body
integrated unit.

Make sure the ignition switch illumination illu-
minates when driver’s side door is open.
Does the ignition switch illumi-
nation illuminate?
Ignition switch illu-
mination is normal.
Go to step 2.
2CHECK THE IGNITION SWITCH ILLUMINA-
TION.
Make sure the ignition switch illumination
blinks when the ignition switch is turned to ON.
Does the ignition switch illumi-
nation blink?
