(b) Malfunctions in the CAN V bus (communication lines) can be checked by measuring the resistance between
terminals of the DLC3. However, an open circuit in a branch line other than the DLC3 branch lines cannot
be checked from the DLC3 (except for the DLC3 branch lines).
Do not insert the tester probes directly into the DLC3. Be sure to use service wires.

7. HOW TO DISTINGUISH CONNECTOR OF CAN JUNCTION CONNECTOR
(a) In the CAN communication system, the shape of connectors connected to the CAN junction connector
which has a ground terminal are the same. The connectors connected to the CAN junction connector can
be distinguished by the colors of the bus lines and the connecting side of the junction connector.
See Terminals of ECU for bus line color or the shape of connectors .
