Mechanical System Tests [08/2013 - ]

WARNING: This page is about a different variant/trim than selected.
  1. SHIFT TIME LAG TEST 
    NOTE:
    • This test must be conducted after checking and confirming that the engine is operating normally.
    • Perform this test while the CVT fluid temperature is between 50 and 100°C (122 and 212°F).
    • Perform this test with the A/C off.

    HINT: 

    When the shift lever is moved while the engine is idling, there will be a certain time lapse or lag before the shock can be felt. This is used for checking the condition of the clutches and brakes.

    1. Connect the Techstream to the DLC3.
    2. Start the engine.
    3. Turn the Techstream on.
    4. Enter the following menus: Powertrain / Engine and ECT / Data List.

      Powertrain > Engine and ECT > Data List 

      Tester Display
      A/T Oil Temperature 1
    5. Drive the vehicle until the CVT fluid temperature has reached 50 to 100°C (122 to 212°F).
    6. Allow the engine to idle with the air conditioning off.
    7. Apply the parking brake and keep the brake pedal depressed firmly.
    8. Check the D position time lag.
      1. Move the shift lever to N and wait for 1 minute.
      2. Move the shift lever to D and measure the time until the shock is felt.
      3. Repeat the 2 steps above 3 times, and calculate the average time of the 3 tests.

        Standard Value

        D position time lag is less than 1.2 seconds.

    9. Check the R position time lag.
      1. Move the shift lever to N and wait for 1 minute.
      2. Move the shift lever to R and measure the time until the shock is felt.
      3. Repeat the 2 steps above 3 times, and calculate the average time of the 3 tests.

        Standard Value

        R position time lag is less than 1.5 seconds.

  2. STALL SPEED TEST 
    WARNING:
    • The stall speed test should always be performed with at least 2 people. One person should observe the condition of the wheels and wheel chocks while the other is performing the test.
    • To ensure safety, perform this test in an open and level area that provides good traction.
    NOTE:
    • The stall speed test should be done on a paved surface (a surface that is not slippery).
    • Do not perform the stall speed test for more than 5 seconds.
    • When performing the stall speed test repeatedly, wait for 15 seconds or more between tests.

    HINT: 

    This test is to check the overall performance of the engine.

    1. Connect the Techstream to the DLC3.
    2. Start the engine.
    3. Turn the Techstream on.
    4. Enter the following menus: Powertrain / Engine and ECT / Data List.

      Powertrain > Engine and ECT > Data List 

      Tester Display
      A/T Oil Temperature 1
    5. Drive the vehicle until the CVT fluid temperature has reached 50 to 100°C (122 to 212°F).
    6. Allow the engine to idle with the air conditioning off.
    7. Chock all 4 wheels.
    8. Enter the following menus: Powertrain / Engine and ECT / Active Test / Connect the TC and TE1.

      Powertrain > Engine and ECT > Active Test 

      Tester Display
      Connect the TC and TE1
    9. Apply the parking brake and keep the brake pedal firmly depressed with your left foot.
    10. Move the shift lever to D.
    11. Depress the accelerator pedal all the way down with your right foot.
    12. Read the engine speed (stall speed) and release the accelerator pedal immediately.
