WARNING: This page is about a different variant/trim than selected.
  1. PERFORM HYDRAULIC TEST 
    1. Measure the line pressure.
      NOTE:
      • Do the test at normal operation ATF temperature 50 to 80 °C (122 to 176 °F). 
      • The line pressure test should always be carried out in pairs. One technician should observe the conditions of wheels or wheel stopper outside the vehicle while the other is doing the test. 
      • Be careful to prevent SST's hose from interfering with the exhaust pipe. 
      1. Warm up the ATF.
      2. Remove the test plug on the transaxle case front left side and connect SST.

        SST 09992-00095 (09992-00231, 09992-00271)

      3. Fully apply the parking brake and chock the 4 wheels.
      4. Connect an OBD II scan tool or hand-held tester to the DLC3.
      5. Start the engine and check the idling speed.

      6. Keep your left foot pressed firmly on the brake pedal and shift into the D position.
      7. Measure the line pressure when the engine is idling.
      8. Depress the accelerator pedal all the way down. Quickly read the highest line pressure when the engine speed reaches the stall speed.
      9. Do the test in the R position in the same way.

      Specified line pressure: 

      PRESSURE SPECIFIED CONDITION

      Condition D position kPa (kgf/cm2 , psi) R position kPa (kgf/cm2 , psi)
      Idling 372 to 412 (3.8 to 4.2, 54 to 60) 553 to 623 (5.6 to 6.4, 80 to 100)
