3. General Description
A: CAUTION
1. SRS AIRBAG SYSTEM
Airbag system wiring harness is routed near the
body integrated unit and twisted pair line.
CAUTION:
•All airbag system wiring harness and con-
nectors are colored yellow. Do not use the elec-
trical test equipment on these circuits.
•Be careful not to damage the airbag system
wiring harness when servicing the body inte-
grated unit and LAN system.
•Refer to “Airbag System” when disconnect-
ing the air bag system connector. CAUTION, General Description.>
2. LAN SYSTEM
•Bus line of LAN system is twisted pair line. Be
careful not to bypass or partly unbind the twisted
pair line.
•Do not make clearance between bus lines (CAN
High, CAN Low).
•Difference of bus line length should be within 10
cm (3.94 in).
•Fray near the connector should be within 8 cm
(3.14 in).
•If the characteristics of the twisted pair line are
changed, it may extremely weaken against noise.
•When repairing the harness, connect the wires
using soldering and protect it with insulating tape
etc.
B: INSPECTION
Before performing diagnostics, check the following
item which might affect body integrated unit mal-
functions.
1) Measure the battery voltage and check electro-
lyte.
Standard voltage: 12 V or more
Specific gravity: Above 1.260
2) Check the fuse condition.
Make sure that ampere of the fuse is setting value,
and it is not blown out.
3) Check the connecting condition of harness and
harness connector.
4) Confirm settings of body integrated unit are cor-
responded to vehicle equipment. ag)-19, REGISTRATION BODY INTEGRATED
UNIT (EQUIPMENT SETTING), OPERATION,

5) Confirm setting are corresponded to vehicle
equipment by function setting (ECM customizing)
of body integrated unit. FUNCTION SETTING (ECM CUSTOMIZING), OP-
ERATION, Subaru Select Monitor.>
6) Confirm “Factory initial setting” of body integrat-
ed unit registrations is “Market”.
7) Confirm key illumination does not blink with igni-
tion switch turned to ON.

B: CAUTION
•Before disassembling or reassembling parts, al-
ways disconnect the battery ground cable from bat-
tery. When repairing the audio, control module, etc.
which are provided with memory functions, record
the memory contents before disconnecting the
ground cable from battery. Otherwise, these con-
tents are erased upon disconnection.
•Reassemble the parts in the reverse order of dis-
assembly unless otherwise indicated.
•Adjust the parts to the specifications described in
this manual if so designated.
•Connect the connectors securely during reas-
sembly.
•After reassembly, ensure the functional parts op-
erate smoothly.
•The air bag system wiring harness is routed near
electrical parts and switches.
•Airbag system wiring harnesses and connectors
are yellow. Do not use the electrical test equipment
on these circuits.
•Be careful not to damage the airbag system wir-
ing harness when servicing the ignition key cylin-
