A/T Road Test (2016-18): Test

  1. Engine - Warm Up
      1. Start the engine. Hold the engine speed at 3, 000 rpm without load (in P or N) until the radiator fan comes on, then let it idle.
  2. HDS DLC - Connect
  3. Vehicle - Road-Test

    4. Apply the parking brake, and block all four wheels

    5. Start the engine

    6. Shift the transmission to D position/mode while pressing the brake pedal. Press the accelerator pedal, and release it suddenly. The engine should not stall

    7. Repeat step 4 in all shift lever positions

    8. Prepare the HDS and the MVCI to take a SNAPSHOT (refer to the HDS user's guide for more details if needed).

    • Set the Trigger Type to Parameter.
    • Adjust the Parameter setting to APP Sensor A above 0.9 V.
    • Set the Recording Time to 60 seconds.
    • Set the Trigger Point to (Negative)-30 seconds.

    7. Find a suitable level road

    8. When you are ready to do the test, press OK on the HDS

    9. Accelerate quickly until APP Sensor A reads 1.0 V. Maintain a steady throttle until the transmission shifts to 6th gear, then slow the vehicle and come to a stop

    10. Save the snapshot if the entire event was recorded or increase the recording time setting as necessary, and repeat step 9

    11. Adjust the Parameter setting to 1.2 V

    12. Accelerate quickly until APP Sensor A reads 1.3 V. Maintain a steady throttle until the transmission shifts to 6th gear, then slow the vehicle and come to a stop

    13. Save the snapshot if the entire event was recorded or increase the recording time setting as necessary, and repeat step 12

    14. Adjust the Parameter setting to 2.2 V

    15. Test-drive the vehicle again. Accelerate quickly until APP Sensor A reads 2.3 V. Maintain a steady throttle until the transmission shifts to 6th gear (or a reasonable speed), then slow the vehicle and come to a stop

    16. Save the snapshot if the entire event was recorded or increase the recording time setting as necessary, and repeat step 15

    17. Accelerate quickly until the accelerator pedal is to the floor. Maintain a steady pedal until the transmission shifts to 5th gear, then slow to a stop, and save the snapshot.

    1. Review each snapshot individually, and compare the Shift Control, APP Sensor A (V), and the Vehicle Speed to the following table.

    2. Drive the vehicle in 5th or 6th gear in S with the sequential shift mode, then decelerate and downshift to 2nd gear. The vehicle should immediately begin to slow down from the engine braking, then slow to a stop.
    3. Shift the transmission to R position/mode, accelerate from a stop to full throttle momentarily, and check for abnormal noise and clutch slippage.
    4. Park the vehicle on an upward slope (about 16 degrees), apply the parking brake, then shift into P. Release the brake; the vehicle should not move.
      NOTE: Always use the parking brake to hold the vehicle when stopped on an incline in gear. Depending on the grade of the incline, the vehicle could roll if the brake is released.
