Yes

No

1

CHECK SECURITY INDICATOR LIGHT.
1) Turn the ignition switch to OFF.
2) Disconnect the harness connector from 
body integrated unit.
3) Connect a resistor (100 

:) between the 

body integrated unit harness connector termi-
nal (i84) No. 33 and chassis ground.

Does the security indicator light 
illuminate?

Go to step 2.

Go to step 5.

2

CHECK BODY INTEGRATED UNIT GROUND 
CIRCUIT.
Measure the resistance between body inte-
grated unit harness connector terminal and 
chassis ground.

Connector & terminal

(B280) No. 22 — Chassis ground:
(B281) No. 8 — Chassis ground:
(B281) No. 9 — Chassis ground:

Is the resistance less than 10 

:? Go to step 3.

Repair the open 
circuit of body inte-
grated unit ground 
circuit.

3

CHECK BODY INTEGRATED UNIT IGNITION 
CIRCUIT.
1) Turn the ignition switch to ON. (engine OFF)
2) Measure the voltage between body inte-
grated unit harness connector terminal and 
chassis ground.

Connector & terminal

(i84) No. 1 (+) — Chassis ground (–):

Is the voltage 10 V or more?

Go to step 4.

Check the harness 
for open or short 
circuit between the 
body integrated 
unit and ignition 
switch.

4

CHECK BODY INTEGRATED UNIT POWER 
SUPPLY CIRCUIT.
1) Turn the ignition switch to OFF.
2) Measure the voltage between body inte-
grated unit harness connector terminal and 
chassis ground.

Connector & terminal

(B280) No. 7 (+) — Chassis ground (–):
(B281) No. 2 (+) — Chassis ground (–):

Is the voltage 10 V or more?

Replace the body 
integrated unit. 
<Ref. to SL-56, 
Body Integrated 
Unit.> Replace all 
ignition keys 
(including the tran-
sponder). Execute 
the registration 
procedure next. 
Refer to the “PC 
application help for 
Subaru Select 
Monitor”.

Check the harness 
for open or short 
circuit between the 
body integrated 
unit and fuse.

5

CHECK COMBINATION METER CIRCUIT.
1) Remove the combination meter. <Ref. to 
IDI-22, Combination Meter.>
2) Measure the voltage between combination 
meter harness connector terminal and chassis 
ground.

Connector & terminal

(i10) No. 1 (+) — Chassis ground (–):

Is the voltage 10 V or more?

Go to step 6.

Check the harness 
for open or short 
between combina-
tion meter and 
fuse.

6

CHECK COMBINATION METER CIRCUIT.
Measure the resistance between the body inte-
grated unit harness connector terminal and 
combination meter harness connector termi-
nals.

Connector & terminal

(i84) No. 33 — (i10) No. 17:

Is the resistance less than 10 

:? LED bulb is defec-

tive. Replace the 
combination meter 
case assembly. 
<Ref. to IDI-23, 
DISASSEMBLY, 
Combination 
Meter.>

Repair the harness 
or connector.
