5. Confirm the unit name that “UNKWN” is displayed on the copy of “CAN DIAG SUPPORT MNTR” screen of “BCM” and “ABS” as well as “ENGINE”. And then, put a check mark to the check sheet table.
NOTE:

For “BCM”, “UNKWN” is displayed on “IPDM E/R”, “METER/M&A” and “I-KEY”. But, put a check mark
to “IPDM E/R” and “METER/M&A” because “UNKWN” is listed on the column of reception diagnosis of
the check sheet table.

For “ABS”, “UNKWN” is displayed on “ECM”, “TCM”, “METER/M&A”, “STRG” and “ICC”. But, put a
check mark to “ECM”, “TCM” and “STRG” because “UNKWN” is listed on the column of reception diag-
nosis of the check sheet table.
