6. REGISTRATION BODY INTEGRATED
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
