Technical Description (Comment)

Current trouble 

• Connector(s) or wiring harness in the CAN bus lines between the ETACS-ECU and the multi-center display unit (middle grade type), the power supply system to the display unit, the display unit itself, or the ETACS-ECU may be defective.

Past trouble 

• Carry out diagnosis with particular emphasis on connector(s) or wiring harness in the CAN bus lines between the ETACS-ECU and the multi-center display unit (middle grade type), and the power supply system to the ETACS-ECU. For diagnosis procedures, refer to "How to cope with past trouble" (Refer to "How to Use Troubleshooting/Inspection Service Points - HOW TO TREAT PAST TROUBLE " ).
  NOTE: For a past trouble, you may not find it by the M.U.T.-III CAN bus diagnostics even if there is any failure in CAN bus lines. In this case, refer to "How to Use Troubleshooting/Inspection Service Points - HOW TO COPE WITH INTERMITTENT MALFUNCTIONS " .) and check the CAN bus lines. You can narrow down the possible cause of the trouble by referring to the DTC, which is set regarding the CAN communication-linked ECUs (Refer to EXPLANATION ABOUT THE SCAN TOOL (M.U.T.-III) CAN BUS DIAGNOSTICS ).
