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, oil, etc.) from the body integrated unit connector during re-
moval and installation.
•For model with immobilizer, registration of immobilizer may be needed after the replacement of
controller etc. For detailed procedure, refer to the REGISTRATION MANUAL FOR IMMOBILIZER.
NOTE:
•To check harness for broken wires or short circuits, shake trouble spot or connector.
•Check List for Interview.
Step Check Yes No
1CHECK PRE-INSPECTION.
1) Ask the customer when and how the trou-
ble occurred using interview check list.
2) Check the display of communication error
display. (Combination meter, odo/trip meter)
Is the communication error dis-
played?
Go to step 3.Go to step 2.
2BASIC INSPECTION
Check the components which might affect
body control.
Is the component that might
influence the body control
problem normal?
Go to step 3.Repair or replace
each component.
3CHECK INDICATION OF DTC.
1) Read DTC of all systems.

UNIT (EQUIPMENT SETTING)
CAUTION:
Body integrated unit is core of LAN system, and
also can select the function of all vehicle sys-
tem control. It is possible to control the original
functions of vehicle when registrations of body
integrated unit and function setting are corre-
sponded to vehicle equipment.
If registrations and function setting are differ-
ent from vehicle equipment, vehicle system
does not operate normally and diagnosis can-
not be performed correctly. Pay attention to fol-
lowing item.
•Be sure to correspond registrations and
function settings to vehicle equipment.
•Do not change the settings of vehicle improp-
erly.
•Confirm key illumination does not blink or
“Factory initial setting” of body integrated unit
registrations is “Market.” If “Factory initial set-
ting” is set to “Factory,” key illumination blinks
with ignition key turned to ON to give warning
of unconfirmed settings.
•Key illumination does not blink with ignition
switch turned to ON and go off with door
closed.
•Be sure to register immobilizer if body inte-
grated unit is replaced with a new one. (Model
with immobilizer)
•Make a registration of immobilizer when the
parts related to immobilizer have been re-
placed. Refer to the “REGISTRATION MANUAL
FOR IMMOBILIZER”.
•Do not install or register an immobilizer relat-
ed module of other registered vehicles to diag-
nose failures or inspect functions.
1) Turn the ignition switch to OFF.
2) Connect the Subaru Select Monitor to data link
connector.
3) Turn the ignition switch to ON and Subaru Select
Monitor to ON.
4) On the «Main Menu» display screen, select the
{Each System Check} and press the [YES] key.
5) On the «Each System Check» display screen,
select the {Integ. Unit mode} and then select the
«ECM customizing».
6) Change the setting with UP/DOWN key and
press the [YES] key.
Also, it is possible to set by changing to factory
mode and pressing the wiper deicer switch, rear
defogger switch, rear fog light switch and door lock
switch.
NOTE:
Center display yes/no can be set only by the select
monitor.

CAUTION:
•It is possible to control the original functions of vehicle when registrations of body integrated
unit and function setting are corresponded to vehicle equipment.
•When body integrated unit is a new one or “Factory” mode, key illumination blinks to show
equipment settings have not been completed.
•Be sure not to change Factory initial setting except installation of new body integrated unit.
NOTE:
“Factory” mode:
•Body integrated unit has not been set yet. It can be recognized by key illumination blinking with ignition
switch turned to ON.
•All body integrated units as part for repair are set to “Factory” mode. When replacing a body integrated
unit, be sure to perform the registration operation.
“Market” mode:
Each settings have been set. It can be recognized by key illumination coming on in concocting with room light
