Road Test

  1. Apply the parking brake, and block both front wheels.
  2. Warm up the engine to normal operating temperature (the radiator fan comes on).
  3. 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) located under the driver's side of the dashboard.

  6. Turn the ignition switch to ON (II).
  7. 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 ).
  8. 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 (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 1.1 V.
    • Set the recording time to 60 seconds.
    • Set the trigger point to (Negative)-30 seconds.
  9. Find a suitable level road. When you are ready to do the test, press OK with the HDS.
  10. Accelerate quickly until APP Sensor A reads 1.2 V. Maintain a steady throttle until the transmission shifts to 5th gear, 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. Adjust the parameter setting to 2.4 V. 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 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 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.
  15. Review each snapshot individually, and compare the Shift Control, the APP Sensor A (V), and the Vehicle Speed to the following table:

    Upshift: D Position 

    SHIFT LEVER POSITION REFERENCE

    APP Sensor A voltage: 1.2 V 
    1st → 2nd 10-12 mph (16-19 km/h)
    2nd → 3rd 17-19 mph (28-31 km/h)
    3rd → 4th 30-35 mph (49-56 km/h)
    4th → 5th 41-46 mph (66-74 km/h)
    Lock-up ON 31-40 mph (50-65 km/h)
    APP Sensor A voltage: 2.5 V 
    1st → 2nd 30-31 mph (48-50 km/h)
    2nd → 3rd 47-50 mph (76-80 km/h)
    3rd → 4th 71-73 mph (115-118 km/h)
    4th → 5th 98-112 mph (157-180 km/h)
    Lock-up ON 93-99 mph (150-160 km/h)
    Fully-opened throttle 
    APP Sensor A voltage: 4.5 V 
    1st → 2nd 36-45 mph (58-72 km/h)
    2nd → 3rd 69-73 mph (111-117 km/h)
    3rd → 4th 104-107 mph (168-172 km/h)
    Lock-up ON 113-114 mph (182-184 km/h)

    Downshift: D Position 

    SHIFT LEVER POSITION REFERENCE

    APP Sensor A voltage: 1.2 V 
    Lock-up OFF 37-39 mph (60-62 km/h)
    5th → 4th 37-38 mph (59-61 km/h)
    4th → 3rd 19-20 mph (30-32 km/h)
    3rd → 1st 7-9 mph (12-14 km/h)
    APP Sensor A voltage: 2.5 V 
    Lock-up OFF 70-72 mph (112-116 km/h)
    Fully-opened throttle 
    APP Sensor A voltage: 4.5 V 
    Lock-up OFF 94-97 mph (152-156 km/h)
    5th → 4th 115-118 mph (185-190 km/h)
    4th → 3rd 86-87 mph (138-140 km/h)
    3rd → 2nd 55-56 mph (88-90 km/h)
    2nd → 1st 28-29 mph (45-47 km/h)
  16. Drive the vehicle in 4th or 5th gear in D, then shift to L. The vehicle should immediately begin to slow down from engine braking.
  17. Shift to L, accelerate from a stop at full throttle, and check for abnormal noise and clutch slippage. Also check that upshifts do not occur.
  18. Shift to R, accelerate from a stop at full throttle momentarily, and check for abnormal noise and clutch slippage.
  19. 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 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.
