CVT Road Test

CVT Road Test

1. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on twice).

2. Apply the parking brake, and block both rear wheels.

3. Shift the shift lever to D while pressing the brake pedal. Press the accelerator pedal, and release it suddenly. The engine should not stall.

4. Repeat step 3 in all shift lever positions.

5. Turn the ignition switch to LOCK (0).

6. Connect the HDS to the DLC (A) located under the driver's side of the dashboard.





7. Turn the ignition switch to ON (II).

8. Make sure the HDS communicates with the PCM, and go to the A/T Data List. If it does not, go to the DLC circuit troubleshooting DLC Circuit Troubleshooting (PGM-FI System).

9. Prepare the HDS to take a HIGH SPEED SNAPSHOT (refer to the HDS user's guide for more details if needed):

- Select the High Speed icon.
- Select these parameters:
- Vehicle Speed
- Output Shaft (Driven Pulley) Speed (rpm)
- Input Shaft (Drive Pulley) Speed (rpm)
- Engine Speed
- APP Sensor A (V)
- Battery Voltage
- Brake Switch

- Set the Trigger Type to Parameter.
- Adjust the Parameter setting to APP Sensor A above 1.1 V.
- Set the recording time to 60 seconds.
- Set the Trigger point to -30 seconds.

10. Find a suitable level road. When you are ready to do the test, press OK on the HDS.

11. Shift the shift lever to D.

12. Monitor the HDS, and accelerate quickly until APP Sensor A reads 1.2 V. Maintain a steady throttle at 1.2 V until the vehicle reaches a reasonable speed, 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. Test-drive the vehicle again. While monitoring the HDS, accelerate quickly until APP Sensor A reads 2.3 V. Maintain a steady throttle at 2.3 V until the vehicle reaches a reasonable speed, then slow the vehicle, and come to a stop.

15. Save the snapshot if the entire event was recorded, or increase the recording time setting as necessary and repeat step 14.

16. Accelerate quickly until the accelerator pedal is to the floor. Maintain a steady pedal until the vehicle reaches to reasonable speed, then slow to a stop, and save the snapshot. Repeat steps 12 thru 16 in D, S, and L positions.

17. Review each snapshot individually, and compare APP Sensor A Voltage, Vehicle Speed, and Engine Speed to the following table:

D Position:





S Position:





L Position:





18. Park the vehicle on a slope (about 16-degrees), apply the brake, and shift into P. Release the brake; the vehicle should not move.

NOTE: Always use the brake to hold the vehicle when stopped on an incline in gear. Depending on the grade of the incline, the vehicle could roll backwards if the brake is released.
