Continuously Variable Transaxle System -- Road Test



PROBLEM SYMPTOM CONFIRMATION

  1. Try to reproduce symptoms based on the result of the customer problem analysis. If the problem is that the transaxle does not change gear ratios or changes ratios at the wrong engine speed, conduct the following road test while referring to the speed variation chart and attempt to duplicate the problem symptoms.


ROAD TEST
CAUTION:
Strictly observe posted speed limits, traffic laws and road conditions when performing the road test.
NOTICE:
  1. This test must be conducted after checking and confirming that the engine is operating normally.
  2. Perform this test while the CVT fluid temperature is between 50 and 100°C (122 and 212°F).
  3. Perform the test with the A/C off.
HINT:
  1. Lock-up control will not operate when the CVT fluid temperature is 40°C (104°F) or less and the vehicle speed is 60 km/h (37 mph) or less, or when the CVT fluid temperature is 5°C (41°F) or less.
  2. Lock-up control will not operate when the engine coolant temperature is 30°C (86°F) or less.
  3. The lock-up off vehicle speed may vary depending on the electrical load, and air conditioning and brake operations.
  4. Keep a constant accelerator pedal angle to maintain the specified vehicle speed.
  5. When fully depressing the accelerator pedal, read the engine speed immediately after the pedal is fully depressed.

HINT:
When checking the engine speed at 70 km/h (43 mph) and 100 km/h (62 mph), check the engine speed directly before the transmission up-shifts.

  1. D position test
    Move the shift lever to D and fully depress the accelerator pedal. Check the following:

    1. Check the up-shift operation.
      Check if the gear ratio changes during normal driving (average urban driving).

    2. Check for abnormal noises and vibration.

      HINT:
      The check for the cause of abnormal noise and vibration must be done thoroughly as it could also be due to loss of balance in the differential, torque converter clutch, etc.

    3. Check the kick-down operation.

      1. With the vehicle stopped, fully depress the accelerator pedal and check the engine speed when the vehicle reaches the vehicle speeds listed in *1, *2 and *3 in the speed variation chart.
      2. With the vehicle stopped, depress the accelerator pedal to a constant intermediate position and check the engine speed when the vehicle reaches the vehicle speed listed in *4 in the speed variation chart.
      3. Release the accelerator pedal and check the engine speed when the vehicle decelerates to the vehicle speed listed in *5 in the speed variation chart.
      4. Depress the accelerator pedal to a constant intermediate position again and check the engine speed when the vehicle reaches the vehicle speed listed in *6 in the speed variation chart.
      5. Fully depress the accelerator pedal and check the engine speed as the vehicle accelerates from the vehicle speed listed in *7 in the speed variation chart.

    4. Check for abnormal shock and slippage at kick-down.

    5. Check the lock-up mechanism.

  2. M position test
    Move the shift lever to M and check the following:

    1. Check the shift operation.

      1. When driving with the M7 range selected (vehicle speed approximately 90 to 100 km/h (56 to 62 mph)), check the engine braking effect in the M6 range when the shift lever is moved to "-" or the "-" shift paddle is operated.
      2. When driving with the M6 range selected (vehicle speed approximately 70 to 80 km/h (43 to 50 mph)), check the engine braking effect in the M5 range when the shift lever is moved to "-" or the "-" shift paddle is operated.
      3. When driving with the M5 range selected (vehicle speed approximately 50 to 60 km/h (31 to 37 mph)), check the engine braking effect in the M4 range when the shift lever is moved to "-" or the "-" shift paddle is operated.
      4. When driving with the M4 range selected (vehicle speed approximately 40 to 50 km/h (25 to 31 mph)), check the engine braking effect in the M3 range when the shift lever is moved to "-" or the "-" shift paddle is operated.
      5. When driving with the M3 range selected (vehicle speed approximately 30 to 40 km/h (19 to 25 mph)), check the engine braking effect in the M2 range when the shift lever is moved to "-" or the "-" shift paddle is operated.
      6. When driving with the M2 range selected (vehicle speed approximately 20 to 30 km/h (12 to 19 mph)), check the engine braking effect in the M1 range when the shift lever is moved to "-" or the "-" shift paddle is operated.

  3. R position test
    Move the shift lever to R and lightly depress the accelerator pedal. Check that the vehicle moves backward without any abnormal noise or vibration.

    CAUTION:
    Before conducting this test, make sure that the test area is free from people and obstructions.

  4. P position test
    Stop the vehicle on an incline (more than 5°). Then move the shift lever to P and release the parking brake. Check that the parking lock pawl holds the vehicle in place.
