Step

Check

Yes

No

1

CHECK IGNITION SWITCH VOLTAGE.
1) Prepare the Subaru Select Monitor kit.
2) Turn the ignition switch to ON (engine OFF) 
and run the “PC application for Subaru Select 
Monitor”.
3) On the «System Selection Menu» display, 
select the {Integ. unit mode}.
4) Select the {Current Data Display & Save}.
5) Check the {BATT voltage} and {IG power 
supply voltage}.

Is the {IG power supply voltage} 
within 

r1 V against {BATT volt-

age}?

The ignition switch 
input circuit is OK.

Go to step 2.

2

CHECK IGNITION SWITCH CIRCUIT.
1) Turn the ignition switch to OFF.
2) Disconnect the harness connector of body 
integrated unit.
3) Turn the ignition switch to ON.
4) Measure the voltage between harness con-
nector terminal and chassis ground.

Connector & terminal

(i84) No. 1 (+) — Chassis ground (–):

Is the voltage 10 V or more?

Check the body 
integrated unit. 
<Ref. to 
LAN(diag)-2, Basic 
Diagnostic Proce-
dure.>

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

Step

Check

Yes

No

1

CHECK DOOR KEY CYLINDER SWITCH 
CIRCUIT.
Measure the resistance between the harness 
connector terminal and chassis ground when 
moving the door key cylinder switch to 
UNLOCK.

Connector & terminal

(i84) No. 12 — Chassis ground:

Is the resistance less than 10 

:? Door key cylinder 

switch is OK.

Go to step 2.

2

CHECK DOOR KEY CYLINDER SWITCH.
1) Disconnect the door key cylinder switch har-
ness connector.
2) Measure the resistance between door key 
cylinder switch terminals when turning the door 
key cylinder switch to LOCK.

Terminals

No. 1 — No. 2:

Is the resistance less than 1 

:? Check the harness 

for open or short 
circuits between 
the body integrated 
unit and the door 
key cylinder switch.

Replace the door 
key cylinder switch.

SECURITY AND LOCKS

5. Front Inner Remote

A: REMOVAL

1) Remove the door trim. <Ref. to EI-49, REMOV-
AL, Door Trim.>
2) Remove the back cover (1) of inner remote.
3) Remove the cable (2).
4) Remove the cable end ball (3).
5) Remove the screws (4), and remove the inner
remote.

B: INSTALLATION

Install in the reverse order of removal.

C: INSPECTION

1) Check the cable of the door opener and door
lock for deformation. When it is deformed, straight-
en it because failure operations may occur. When it
is unrepairable, replace the front door latch and
door lock actuator assembly.
2) Check the handle and cable for smooth opera-
tion.
