Road Test

  1. Warm up the engine to normal operating temperature (the radiator fan comes on).
  2. Apply the parking brake, and block all four wheels. Start the engine, then shift to D while pressing the brake pedal. Press the accelerator pedal, and release it suddenly. The engine should not stall.
  3. Repeat step  2 in all shift lever positions.
  4. Connect the HDS to the DLC (A) located under the driver's side of the dashboard.

  5. Turn the ignition switch to ON (II).
  6. 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 (see DLC CIRCUIT TROUBLESHOOTING ).
  7. Prepare the HDS to take a HIGH SPEED SNAPSHOT (refer to the HDS user's guide for more details if needed):
    • Select High Speed icon.
    • Select these parameters:
      • Vehicle Speed
      • Output Shaft (Countershaft) Speed (rpm)
      • Input Shaft (Mainshaft) Speed (rpm)
      • Engine Speed
      • TP Sensor
      • APP Sensor A (V)
      • ETR
      • Battery Voltage
      • Shift Control
      • Brake Switch
    • Set the Trigger Type to Parameter.
    • Adjust the Parameter setting to APP Sensor A above 1.11 V.
    • Set the recording time to 60 seconds.
    • Set the trigger point to (Negative)-30 seconds.
  8. Find a suitable level road. When you are ready to do the test, press OK on the HDS.
  9. Accelerate quickly until APP Sensor A reads 1.21 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 2.18 V. Test-drive the vehicle again. Accelerate quickly until APP Sensor A reads 2.28 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.
  12. Save the snapshot if the entire event was recorded or increase the recording time setting as necessary, and repeat step  11.
  13. 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.
    NOTE: Only perform the full throttle test pass the 2-3 shift if road conditions and local law/regulations allow it.
  14. Review each snapshot individually, and compare the Shift Control, APP Sensor A (V), and the Vehicle Speed to the following table.

  15. Drive the vehicle in 5th or 6th gear in S with the sequential sportshift 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.
  16. Shift to R, accelerate from a stop at to full throttle momentarily, and check for abnormal noise and clutch slippage.
  17. 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.
