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).
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 CAN DIAG SUPPORT MNTR (without PAST), “UNKWN” is indicated even though the item is not used
in the trouble diagnosis. For the details of each item on CAN diagnostic support monitor, refer to LAN-44,
"CAN Diagnostic Support Monitor" .
