2.PREPARATION BEFORE OPERATION
With M.U.T.-III SE
  1. Start the engine.
  2. Select "Data List" in "TRANSMISSION".
  3. Select "FLUID TEMP".
  4. Confirm that the CVT fluid temperature is in the following range.
    FLUID TEMP: 20°C (68°F) or more
With GST
  1. Start the engine.
  2. Set the CVT fluid to 20°C (68°F) or more.
    noteWhen the ambient temperature is 20°C (68°F), the CVT fluid usually increases to 50 to 80°C (122 to 176°F) with driving in an urban area for approximately 10 minutes.
Is the CVT fluid 20°C (68°F) or more?
.
  1. Warm the transaxle.
  2. .
 
3.CHECK DTC DETECTION
  1. Drive the vehicle.
  2. Maintain the following conditions for 30 seconds or more.
    Shift position: "D" position
    Accelerator pedal position: 0.5/8 or more
    Vehicle speed: 40 km/h (25 MPH) or more
  3. Stop the vehicle.
  4. Check the first trip DTC.
