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.
  3. 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.
  4. Repeat step  3 in all shift lever positions.
  5. Connect the HDS to the DLC (A), and go to the A/T data list. If the HDS does not communicate with the PCM, troubleshoot the DLC circuit (see DLC CIRCUIT TROUBLESHOOTING ).

  6. 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 (1) -APP Sensor A (V)
      • ATF Temp Sensor (V)
      • Battery Voltage
      • Shift Control
      • Brake Switch
    • Set the Trigger Type to Parameter.
    • Adjust the Parameter setting to APP Sensor A above 1.25 V.
    • Set the recording time to 60 seconds.
    • Set the trigger point to -30 seconds.
  7. Find a suitable level road. When you are ready to do the test, press OK on the HDS.
  8. Monitor the HDS, and accelerate quickly until the APP Sensor A reads 1.26 V. Maintain a steady throttle until the transmission shifts to 5th gear, then slow the vehicle and come to a stop.
  9. Save the snapshot if the entire event was recorded, or increase the recording time setting as necessary and repeat step  8.
  10. Adjust the parameter setting to 2.52 V. Test-drive the vehicle again. While monitoring the HDS, accelerate quickly until the APP Sensor A reads 2.53 V. Maintain a steady throttle until the transmission shifts to 5th gear (or reasonable speed), then slow the vehicle and come to a stop.
  11. Save the snapshot if the entire event was recorded, or increase the recording time setting as necessary and repeat step  10.
  12. 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.
  13. Review each snapshot individually, and compare the Shift Control, the APP Sensor A voltage, and the Vehicle Speed to the following table.

    3rd → 4th 92-96 mph (148-154 km/h)

    Downshifting in D (Reference) 

    REFERENCE CHART

    Accelerator pedal position sensor A voltage: 1.26 V
    Lock-up OFF 28-30 mph (45-49 km/h)
    5th → 4th 27-31 mph (44-50 km/h)
    4th → 3rd 20-22 mph (32-36 km/h)
    3rd → 1st 5-7 mph (8-12 km/h)
    Accelerator pedal position sensor A voltage: 2.53 V 
    Lock-up OFF 74-78 mph (119-125 km/h)
    Fully-opened throttle 
    Accelerator pedal position sensor A voltage: 4.50 V 
    Lock-up OFF 106-109 mph (170-176 km/h)
    5th → 4th 111-114 mph (178-184 km/h)
    4th → 3rd 77-81 mph (124-130 km/h)
    3rd → 2nd 49-53 mph (79-85 km/h)
    2nd → 1st 22-26 mph (36-42 km/h)
  14. Check for engine braking under these conditions:
    • Seven-position transmission: Drive the vehicle in 4th or 5th gear in D, then shift to 2. The vehicle should immediately begin to slow down from engine braking.
    • Five-position transmission: Drive the vehicle in 4th or 5th gear in S with sequential sportshift mode, then downshift to 2nd gear by pulling the paddle shifter - (downshift switch). The vehicle should immediately begin to slow down from engine braking.
  15. For seven-position transmission: 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.
  16. For seven-position transmission: 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.
  17. Shift to R. Then, from a full stop, accelerate at full throttle, and check for abnormal noise and clutch slippage.
  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 if the brake is released.
