    2. A01O8IJ

      Remove the fluid pump cover plug and O-ring from the hybrid vehicle transaxle assembly.

    3. A01O8ESN01

      Install SST to the hybrid vehicle transaxle assembly.

      SST
      09993-19015   ( 09993-00020, 09993-00030 )

    4. Put the engine in inspection mode.

    5. Measure the fluid pressure.

      Standard
      Engine Speed Fluid Temperature Transaxle Fluid Pressure
      1000 rpm 20 to 50 °C (68 to 122 °F)

      6 kPa (0.06 kgf/cm2, 0.87 psi) or more

      Note

      Be sure to cancel the inspection mode immediately after the hybrid transaxle fluid pressure check is completed.

    6. Remove SST from the hybrid vehicle transaxle assembly.

    7. Install a new O-ring and fluid pump cover plug to the hybrid vehicle transaxle assembly.

      Torque:
      8.0 N*m  { 82 kgf*cm, 71 in.*lbf }

    8. Install the rear engine under cover LH.

  2. ROAD TEST

    CAUTION:

    Confirm the safety of the working environment, then start the inspection.

    Note


    • Perform engine inspection and adjustment before starting a road test.

    • Perform a road test at normal operating fluid temperature 50 to 80°C (122 to 176°F).

    • Make sure the air conditioning switch and cruise control switch are off.

    Load Test Table
    Check Item Check Procedure
    S position test With the shift lever in S (while the vehicle is stopped), move the shift lever to "+" to check that the shift position indicated on the combination meter changes as follows: 1 → 2, 2 → 3, 3 → 4, 4 → 5 and 5 → 6.
    Downshifting

    While driving with the S3 range selected and a vehicle speed of approximately 92 km/h (57 mph), move the shift lever to "-" and check that the transmission shifts to the S2 range.

    Tech Tips

    If the vehicle speed exceeds 94 km/h (58 mph), downshifting cannot be performed.

    While driving with the S2 range selected and a vehicle speed of approximately 53 km/h (33 mph), move the shift lever to "-" and check that the transmission shifts to the S1 range.

    Tech Tips

    If the vehicle speed exceeds 55 km/h (34 mph), downshifting cannot be performed.
    P position test Stop the vehicle on an incline (more than 5°) and after moving the shift lever to P, release the parking brake and check that the parking lock pawl holds the vehicle in place.
    Noise and vibration Check for noise and vibration when driving the vehicle and during gear changes.
    Fluid leaks After performing a road test, check for fluid leaks.
