Basic Diagnostic Procedure
LAN SYSTEM (DIAGNOSTICS)
1. Basic Diagnostic Procedure
A: PROCEDURE
1. WITH SUBARU SELECT MONITOR
CAUTION:
• Subaru Select Monitor is required for reading DTC, performing diagnosis and reading current data.
• Remove foreign matter (dust, water and oil etc.) from the body integrated unit connector during removal and installation.
• For the model with immobilizer, registration of immobilizer may be needed after the replacement of
controller and etc. For detail procedure, refer to “REGISTRATION MANUAL FOR IMMOBILIZER”.
NOTE:
• To check harness for broken wires or short circuits, shake it while holding it or the connector.
• Check List for Interview <Ref. to LAN(diag)-3, Check List for Interview.>

Step
CHECK PRE-INSPECTION.
1) Ask the customer when and how the trouble occurred using interview check list. <Ref. to
LAN(diag)-3, Check List for Interview.>
2) Check the display of freeze frame data.
(Combination meter, odo/trip meter)
BASIC INSPECTION.
Check the components which might affect
body control. <Ref. to LAN(diag)-5, INSPECTION, General Description.>
CHECK INDICATION OF DTC.
1) Read the DTC. <Ref. to LAN(diag)-14,
READ DIAGNOSTIC TROUBLE CODE (DTC),
OPERATION, Subaru Select Monitor.>
Check
Is freeze frame data displayed?
Yes
Go to step 3.
No
Go to step 2.
Is the component that might
influence the body control
problem normal?
Go to step 3.
Repair or replace
each unit.
Is DTC displayed?
Go to step 5.
Go to step 4.
NOTE:
If the communication function of the Subaru Select Monitor cannot be executed normally,
check the communication circuit. <Ref. to
LAN(diag)-30, COMMUNICATION FOR INITIALIZING IMPOSSIBLE, Diagnostic Procedure with Diagnostic Trouble Code (DTC).>
2) Record all DTCs and freeze frame data.
PERFORM THE GENERAL DIAGNOSTICS. Is result of inspection OK?
Inspect using “General Diagnostics Table”.
<Ref. to LAN(diag)-79, General Diagnostic
Table.>
PERFORM THE DIAGNOSIS.
Is DTC displayed?
1) Fix the wrong part.
2) Perform the clear memory mode. <Ref. to
LAN(diag)-20, CLEAR MEMORY MODE,
OPERATION, Subaru Select Monitor.>
3) Read DTC. <Ref. to LAN(diag)-14, READ

3. General Description
• When repairing the harness, connect the wires
using soldering and protect it with insulating tape,
etc.
A: CAUTION
1. SRS AIRBAG SYSTEM
Airbag system wiring harness is routed near the
body integrated unit and twisted pair line.
(A)
CAUTION:
• All airbag system wiring harness and connectors are colored yellow. Do not use the electrical test equipment on these circuits.
• Be careful not to damage the Airbag system
wiring harness when servicing the body integrated unit and LAN system.
LAN00080
(A) Soldering and protection with insulating tape
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
(3.94 in).
(A)
LAN00081
(A) Bypass wire connection
• If the characteristics of the twisted pair line is
changed, it may cause extremely weakness to the
noise.
B: INSPECTION
Before performing diagnostics, check the following
items which might affect body integrated unit malfunctions.
1) Measure the battery voltage and check electrolyte.
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 corresponded to vehicle equipment. <Ref. to LAN(diag)-18, REGISTRATION BODY INTEGRATED
UNIT (EQUIPMENT SETTING), OPERATION,
Subaru Select Monitor.>
5) Confirm setting are corresponded to vehicle
equipment by function setting (ECM customizing)
of body integrated unit. <Ref. to LAN(diag)-20,
FREEZE FRAME DATA, OPERATION, Subaru
Select Monitor.>
6) Confirm “Factory initial setting” of body integrated unit registrations is “Market”.
7) Confirm key illumination does not blink with ignition switch turned to ON.
