NOTE:

  

DTC CONFIRMATION PROCEDURE
1.PERFORM DTC CONFIRMATION PROCEDURE

  1. Turn the ignition switch ON under the following conditions and wait for at least 1 second.
    • CVT selector lever is in the P or N position
    • Do not depress the brake pedal
  1. Check "Self diagnostic result" with CONSULT-III. Is DTC detected?

YES >> Refer to Diagnosis Procedure.
NO >> Inspection End.

Diagnosis Procedure
1.Inspection START
