d. Reception item of "BCM": On "TCM", "UNKWN" is indicated. This means BCM cannot receive the signal from TCM. Draw a line to

indicate an error between BCM and TCM (line 2-d in the figure below).

e. Reception item of "EPS" and "I-KEY": "UNKWN" is not indicated. This indicates normal communication between EPS and I-KEY and their

receiving units. Do not draw any line.

NOTE:  On bus check (without PAST), "UNKWN" is indicated even though the item is not used in the trouble diagnosis. For the details of
each item on bus check, refer to [Bus Check].  See: Scan Tool Testing and Procedures
