•  Use the chart below to verify the symptoms of the trouble in order to diagnose the appropriate area.
Note
•  If a tire of a different diameter from the standard tire is installed, the TCM determines that the driving mode is the AAS mode, and may change to a different shift timing from the normal timing.
•  The TCC operation exists in 2GR to 6GR.

No.
