1. Apply the parking brake, and block both rear
wheels.
2. Start the engine, and warm it up 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), and go to the A/T Data List. Make sure the HDS communicates with
the PCM. If it does not, go to the DLC circuit
troubleshooting (see page 11- 204).7. Prepare the HDS to take a HIGH SPEED SNAPSHOT
(refer to the HDS user 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
– 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 1.2 V.
 Set the recording time to 60 seconds.
 Set the Trigger point to 30 seconds.
8. Find a suitable level road. When you are ready to do the test, press OK on the HDS.
9. Monitor the HDS and accelerate quickly until the 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. Retest-drive the vehicle. While monitoring the HDS, accelerate
quickly until the 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.
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 3rd gear, then slow to a stop,
and save the snapshot.

2nd 1st 42 52 km/h (26 32 mph)
15. Drive the vehicle in 4th or 5th gear with the shift lever in S with the sequential sportshift mode, then
decelerate and downshift to 2nd gear by pressing
the paddle shifter (downshift switch). 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 full throttle momentarily, and check for abnormal noise and
clutch slippage. 17. 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.
