  • Make sure that no DTCs are output. If any DTCs are output, proceed to the Diagnostic Trouble Code Chart.
  • After completing repairs, confirm that the problem does not recur.
  • After repair, confirm that no DTCs are output by performing "DTC Output Confirmation Operation".
  • When replacing the combination meter assembly, always replace it with a new one. If a combination meter assembly which was installed to another vehicle is used, the information stored in it will not match the information from the vehicle and a DTC may be stored.
