When Replacing The TCM

  1. Turn the ignition switch to the "LOCK" (OFF) position. Then, connect scan tool (M.U.T.-IIISE) to the data link connector.
  2. Turn the ignition switch to the "ON" position.
  3. Execute the special function "Write calibration value (Calibration value Read&save)" on the scan tool (M.U.T.-IIISE) to read a serial number which is stored in the TCM.
  4. Make sure that the read serial number corresponds with the one stamped on the CVT assembly (see illustration).
    NOTE: If it does not correspond, observe the following procedure.

    1. Remove the oil pan (Refer to OIL PAN AND VALVE BODY ASSEMBLY ), and check the serial number of the valve body assembly shown in the illustration.
    2. If no serial number is stamped on the valve body assembly, import data from the server to the scan tool (M.U.T.-IIISE) according to the serial number on the CVT assembly.
    3. If a serial number is stamped on the valve body assembly, make sure that the read serial number corresponds with the one stamped on the valve body assembly (see illustration).

      YES: Store the serial number in the scan tool (M.U.T.-IIISE). 

      NO: Import data from the server to the scan tool (M.U.T.-IIISE) according to the serial number on the valve body assembly. 

  5. Store the serial number in the scan tool (M.U.T.-IIISE).
    NOTE: Be sure to write down the serial number. The serial number will be needed to compare it with the number imported into the scan tool (M.U.T.-IIISE) and to select the number.
  6. Turn the ignition switch to the "LOCK" (OFF) position.
  7. Remove the TCM and install a new TCM (Refer to TRANSAXLE CONTROL MODULE (TCM) ).
  8. Turn the ignition switch to the "ON" position.
  9. 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.

  10. Execute the special function "Write calibration value (Saved calibration value writing)" on the scan tool (M.U.T.-IIISE) to write the serial number into the TCM.
  11. 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, observe the following procedure.
    1. Move the selector lever to the R range. 
    2. Depress the accelerator pedal while depressing the brake pedal. (Engine stops.) Use the scan tool (M.U.T.-IIISE) special function to execute "Calibration value reset (item No. 1: Calibration value reset)" while holding them in applied position. 
    3. Set the selector lever to the P range. 
    4. Turn the ignition switch to the "LOCK" (OFF) position, and then wait for ten seconds. 
    5. Repeat from Step   2 . 
  12. Make sure that the serial number on "Saved calibration value writing" completion screen corresponds with the serial number of the CVT assembly (or the valve body assembly) that was written down earlier.
    NOTE: If it does not correspond, observe the following procedure.
    1. Move the selector lever to the R range. 
    2. Depress the accelerator pedal while depressing the brake pedal. (Engine stops.) Use the scan tool (M.U.T.-IIISE) special function to execute "Calibration value reset (item No. 1: Calibration value reset)" while holding them in applied position. 
    3. Set the selector lever to the P range. 
    4. Turn the ignition switch to the "LOCK" (OFF) position, and then wait for ten seconds. 
    5. Repeat from Step   10 . 
  13. Turn the ignition switch to the "LOCK" (OFF) position.
  14. 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.
  15. Operation complete.
