A/T Road Test

A/T Road Test

Test

1. Warm Up The Engine

Start the engine. Hold the engine speed at 3,000 rpm without load (A/T in P or N, M/T in neutral) until the radiator fan comes on, then let it idle.

2. HDS DLC - Connection





1. Connect the HDS to the data link connector (DLC) (A) located under the driver's side of the dashboard.

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

3. Make sure the HDS communicates with the vehicle. If it does not communicate, go to the DLC circuit troubleshooting.

3. Automatic Transmission Road - Test

1. Park the vehicle on the level ground.

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

3. Start the engine.

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

5. Repeat step 4 in all shift lever positions.

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

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 1.3 V. Maintain a steady throttle until the transmission shifts to 5th 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 2.4 V.

12. Test-drive the vehicle again. Accelerate quickly until APP Sensor A reads 2.5 V. Maintain a steady throttle until the transmission shifts to 5th gear (or 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. Accelerate quickly until the accelerator pedal is to the floor. Maintain a steady pedal until the transmission shifts to 3rd gear, then slow to a stop, and save the snapshot.

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














16. Drive the vehicle in 4th or 5th gear, then shift to 2nd gear. The vehicle should immediately begin to slow down from engine braking.

17. Shift to 1, accelerate from a stop at full throttle, and check for abnormal noise and clutch slippage. Upshifts should not occur in this position.

18. Shift to 2, accelerate from a stop at full throttle, and check for abnormal noise and clutch slippage. Upshifts and downshifts should not occur in this position.

19. Shift to R, accelerate from a stop at to full throttle momentarily, and check for abnormal noise and clutch slippage.

20. Park the vehicle on an upward slope (about 16 degrees), apply the parking brake, and 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.
