CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM > ROAD TEST

for Preparation Click here

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 referring to the speed variation chart and attempt to duplicate the problem symptoms.
   

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 to 100°C (122 to 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 kicking down with the accelerator pedal, read the engine speed immediately after the pedal is pushed down.
   

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

   1. Check 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 kick-down operation.
      Check if the kick-down engine speeds are as specified 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 (for Multi-mode Automatic Transmission)
   Move the shift lever to M and check the following:
   
   

   1. Check shift operation
      

      1. When driving with the S7 range selected (vehicle speed approximately 90 to 100 km/h (56 to 62 mph)), check that the engine braking effect operates in the S6 range when the shift lever is moved to "-".
         
      2. When driving with the S6 range selected (vehicle speed approximately 70 to 80 km/h (43 to 50 mph)), check that the engine braking effect operates in the S5 range when the shift lever is moved to "-".
         
      3. When driving with the S5 range selected (vehicle speed approximately 50 to 60 km/h (31 to 37 mph)), check that the engine braking effect operates in the S4 range when the shift lever is moved to "-".
         
      4. When driving with the S4 range selected (vehicle speed approximately 40 to 50 km/h (25 to 31 mph)), check that the engine braking effect operates in the S3 range when the shift lever is moved to "-".
         
      5. When driving with the S3 range selected (vehicle speed approximately 30 to 40 km/h (19 to 25 mph)), check that the engine braking effect operates in the S2 range when the shift lever is moved to "-".
         
      6. When driving with the S2 range selected (vehicle speed approximately 20 to 30 km/h (12 to 19 mph)), check that the engine braking effect operates in the S1 range when the shift lever is moved to "-".
         

3. S position test (except Multi-mode Automatic Transmission)
   Move the shift lever to S and check the following:
   
   

   1. Check shift operation
      

      1. Check if the shift pattern changes in accordance with the S position pattern as specified in the speed variation chart.
         
      2. Check for appropriate engine braking force while driving at approx. 40 km/h (24 mph) with the shift lever in S.
         

4. B position test (except Multi-mode Automatic Transmission)
   Move the shift lever to B and check the following:
   

   1. Check if the shift pattern changes in accordance with the B position pattern as specified in the speed variation chart.
      
   2. Check for appropriate engine braking force while driving at approx. 40 km/h (24 mph) with the shift lever in B.
      

5. 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 ensure that the test area is free from people and obstructions.

6. 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.
