    NOTE: After driving, use the Subaru Select Monitor to check that «Imbalance Check 3 R» indicates «1», and read the temporary code. If «Imbalance Check 3 R» indicates «0», the diagnosis has not been completed. In this case, repeat driving until the reading becomes «1».

    Perform the followings for catalyst system bank 1 only.

    Check that «Catalyst monitoring completed»* indicates «YES», and read the temporary code.

    If «Catalyst monitoring completed»* indicates «NO», the diagnosis has not been completed yet. In this case, repeat driving until it indicates «YES».

    * Using Subaru Select Monitor, refer to "Engine Current Data Display".
