Technical Description (Comment)

CAUTION: If the ignition switch is turned to the ON position without starting the engine, DTC (past trouble) 011, 012 and 013 may be set to the combination meter (incorporating meter-ECU) after three minutes.

Current trouble

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

Past trouble

Carry out diagnosis with particular emphasis on connector(s) or wiring harness in the CAN bus lines between the combination meter and the multi-center display unit (middle grade type), the power supply system to the display unit. 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 ).
