TROUBLE DIAGNOSIS
Example: Data link connector branch line open circuit
NOTE:
 When data link connector branch line is open, transmission and reception of CAN communication signals
are not affected. Therefore, no symptoms occur. Ho wever, be sure to repair malfunctioning circuit.
 When data link connector branch line is open, “ECU list” displayed on the CONSULT-III “CAN DIAG SUP-
PORT MNTR” may be the same as when the CAN communication line has short-circuit. However, symp-
toms differ depending on the case. See below chart for the differences.
EPS control unit No rmal operation.
Combination meter  Shift position indicator and OD OFF indicator turn OFF.
 Warning lamps turn ON.
ABS actuator and electric unit (control unit) Normal operation.
TCM No impact on operation.
