When Replacing The CVT Assembly

  1. Note the serial number, which is stamped on the new CVT assembly.
  2. Remove the CVT assembly and install a new CVT assembly (Refer to TRANSAXLE ASSEMBLY  ).
  3. Connect scan tool (M.U.T.-III) to the data link connector.
  4. Turn the ignition switch to the "ON" position.
  5. Import a serial number from the CD-R*, which is supplied with a new CVT assembly, into the scan tool (M.U.T.-III).
    NOTE: *: Follow the steps below to import a serial number from the CD-R into the scan tool (M.U.T.-III).
    1. Select "Special function." 
    2. Select "Write calibration value." 
    3. Select "Saved calibration value writing." 
    4. Press the "File import" button. 
    5. Select an appropriate removable disc. 
    6. Confirm that "Completed." is displayed. 
  6. Move the selector lever to the R range.
  7. Depress the accelerator pedal while depressing the brake pedal. (Engine stops.) Use the scan tool (M.U.T.-III) special function to execute "Calibration value reset (item No. 1: Calibration value reset)" while holding them in applied position.
  8. Set the selector lever to the P range.
  9. Turn the ignition switch to the "LOCK" (OFF) position, and then wait for ten seconds.
  10. Turn the ignition switch to the "ON" position.
  11. Make sure that the selector lever is in the P or N range and that P or N is not displayed on the combination meter.
  12. Select the same file name (shown in the illustration) as the serial number of CD-R or CVT assembly on the special function "Write calibration value (Saved calibration value writing)" screen and import the serial number into the TCM.
  13. The shift range symbol (P or N) in the combination meter should illuminate.
    NOTE: If the shift range symbol (P or N) in the combination meter does not illuminate, repeat the operations from Step  5.

    NOTE: If it does not correspond, repeat the operations from Step  5.
  15. Turn the ignition switch to the "LOCK" (OFF) position, and then wait for ten seconds.
  16. Observe the operations below:
    1. Wait until the engine is warmed up. Then road test the vehicle for approx. one minute at 40 km/h (25 mph) or more. Consequently, check whether the CVT is in the following conditions.
      • No CVT-related diagnostic trouble code is set.
      • A diagnostic trouble code is set, but you cannot identify any trouble symptoms (e.g. abnormal noise).
      • There is no fluid leak.
    2. Start the engine.
    3. Teach the system a meeting point. All of the following conditions must be satisfied for approximately 90 seconds.
      • The vehicle is stationary.
      • Engine speed: 500 - 850 r/min (Idling)
      • Brake pedal: Depress
      • Accelerator pedal: Release
      • Selector lever position: D
      • Transmission fluid temperature: 40 - 100°C (104 - 212°F)
    4. Turn the ignition switch to the "LOCK" (OFF) position.
  17. Turn the ignition switch to the "ON" position.
  18. Execute the special function "CVT oil degradation level (item No. 1: Clear CVT oil degradation level)" on the scan tool (M.U.T.-III) to delete a transmission fluid deterioration level.
