WARNING: This page is about a different car, the 2003 Subaru Outback. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
Do not connect any scan tools other than OBD-II general scan tools and Subaru Select Monitor, because the circuit for the Subaru Select Monitor may be damaged.
This connector is used both for OBD-II general scan tools and Subaru Select Monitor. Terminal No. 4 to No. 6 of the data link connector is used for the Subaru Select Monitor signal. See Fig 1 .
