Unit name Symptom
ECM Normal operation.
BCM
EPS control unit
Combination meter
ABS actuator and electric unit (control unit)
TCM
IPDM E/R
NOTE:
  • When data link connector branch line is open, transmission and reception of CAN communication signals are not affected. Therefore, no symptoms occur. However, be sure to repair malfunctioning circuit.
  • The model (all units on CAN communication system are Diag on CAN) cannot perform CAN diagnosis with M.U.T.-III SE if the following error occurs. The error is judged by the symptom.
Error Difference of symptom
Data link connector branch line open circuit Normal operation.
CAN-H, CAN-L harness short-circuit Most of the units which are connected to the CAN communication system enter fail-safe mode or are deactivated.

Example: Main Line Between Data Link Connector and ABS Actuator and Electric Unit (Control Unit) Open Circuit
