Example: Data link connector branch line open circuit
NOTE:

When data link connector branch line is open, transmission and reception of CAN communication signals
is not affected. Therefore, no symptoms occur. However, be sure to repair malfunctioning circuit.

When data link connector branch line is open, the screen-display of the CONSULT-II “SELECT SYSTEM”
screen may be the same as when the CAN communication line has short-circuit. However, symptoms dif-
fer depending on the case. See below chart for the differences.
