“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
and going off with ignition switch turned to ON.
7) Perform the Factory setting. On the «ECM customizing” display screen of Subaru Select Monitor, select
the {Factory initial setting} and press the [YES] key.
8) Change the mode from Factory to Market.
9) Register the immobilizer key.
10) Perform the registration according to the procedures of the “IMMOBILIZER REGISTRATION OPERA-
TION MANUAL”.
