Road Test

  1. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on).
  2. Apply the parking brake, and block all four wheels. Shift to the 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). 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 ).
  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
      • 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 1.12 V.
    • Set the recording time to 60 seconds.
    • Set the trigger point to (Negative) -30 seconds.
  7. Find a suitable level road. When you are ready to do the test, press OK with the HDS.
  8. Monitor the HDS, and accelerate quickly until APP Sensor A reads 1.22 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 2.43 V. Test-drive the vehicle again. While monitoring the HDS, accelerate quickly until 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 4th 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.
  13. Review each snapshot individually, and compare the Shift Command, the APP Sensor A (V), and the Vehicle Speed to following the table:
    UPSHIFT: D POSITION

    APP sensor A voltage: 1.22 V 
    1st→2nd 8-12 mph (14-18 km/h)
    2nd→3rd 17-21 mph (28-34 km/h)
    3rd→4th 27-33 mph (44-52 km/h)
    4th→5th 42-50 mph (69-79 km/h)
    Lock-up ON 36-42 mph (59-67 km/h)
    APP sensor A voltage: 2.53 V 
    1st→2nd 24-28 mph (39-45 km/h)
    2nd→3rd 44-52 mph (72-82 km/h)
    3rd→4th 65-73 mph (105-117 km/h)
    4th→5th 88-98 mph (142-156 km/h)
    Lock-up ON 93-103 mph (150-164 km/h)
    Fully-opened throttle APP sensor A voltage: 4.50 V 
    1st→2nd 38-46 mph (62-72 km/h)
    2nd→3rd 65-73 mph (105-117 km/h)
    3rd→4th 101-111 mph (161-177 km/h)
    Lock-up ON 133-145 mph (213-231 km/h)
    DOWNSHIFT: D POSITION

    APP sensor A voltage: 1.22 V 
    Lock-up OFF 35-41 mph (57-65 km/h)
    5th→4th 35-41 mph (55-65 km/h)
    4th→3rd 18-22 mph (29-35 km/h)
    3rd→1st 6-10 mph (10-16 km/h)
    APP sensor A voltage: 2.53 V 
    Lock-up OFF 75-83 mph (119-133 km/h)
    Fully-opened throttle APP sensor A voltage: 4.50 V 
    Lock-up OFF 120-132 mph (193-211 km/h)
    5th→4th 117-129 mph (188-204 km/h)
    4th→3rd 86-96 mph (138-152 km/h)
    3rd→2nd 56-64 mph (90-102 km/h)
    2nd→1st 30-36 mph (47-57 km/h)
  14. Drive the vehicle in 4th or 5th gear with the shift lever in D, then shift to 2. The vehicle should immediately begin to slow down from engine braking.
  15. Shift to 1, accelerate from a stop at full throttle, and check for abnormal noise and clutch slippage. Also check that upshifts do not occur.
  16. Shift to 2, accelerate from a stop at full throttle, and check for abnormal noise and clutch slippage. Also check that upshifts and downshifts do not occur.
  17. Shift to R, accelerate from a stop at full throttle momentarily, 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 backwards if the brake is released.
