How to use this Service Information .
- Vehicle - Road Test
■ Preconditions
- Engine Warmed Up (the radiator fan comes on twice)
- HDS Connected
■ Procedure/Specifications
1. Park the vehicle on level ground.
2. Apply the parking brake, and block all four wheels.
3. Start the engine.
4. Shift the transmission to D position/mode while pressing the brake pedal. Press the accelerator pedal, and release it. The engine should not stall.
5. Repeat step 4 in S and R position/mode.
6. Prepare the HDS to take a SNAPSHOT (refer to the HDS user's guide for more details if needed).
- Set the Trigger Type to Parameter.
- Adjust the Parameter setting of the Accelerator Pedal Position to 9 %.
- Set the Record Time to 60 seconds.
- Set the Trigger Point to (Negative)-30 seconds.
7. Find a suitable level road.
8. When you are ready to do the test, press OK on the HDS.
9. Accelerate quickly until the Accelerator Pedal Position reads 10 %. Maintain a steady throttle until the vehicle reaches a reasonable speed, then slow down 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 39 %.
12. Test-drive the vehicle again. Accelerate quickly until the Accelerator Pedal Position reads 40 %. Maintain a steady throttle until the vehicle reaches a reasonable speed, then slow down 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 vehicle reaches a reasonable speed, then slow down to a stop, and save the snapshot.
15. Review each snapshot individually, and compare the Gear Shifting, the Accelerator Pedal Position, and the Vehicle Speed to the following table.

Drive the vehicle in 10th gear, then decelerate and downshift to 2nd gear. The vehicle should immediately begin to slow down from the engine braking, then slow down to a stop.
17. Shift the transmission to R position/mode, accelerate from a stop to full throttle momentarily, and check for abnormal noise and clutch slippage.
18. Park the vehicle on an upward slope (about 16°), apply the parking brake, then shift the transmission to P position/mode. Release the parking 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 parking brake is released.
