c. Reception item of “AV”: “UNKWN” is not indicat ed. This indicates normal communication between AV and
its receiving units. Do not draw any line.
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
