A/T Road Test

1.Warm up the engine to normal operating temperature (the radiator fan comes on).

2.Apply the parking brake, and block both rear wheels.

3.Start the engine, then shift to the D position 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.

NOTE: If the HDS does not communicate with the PCM, troubleshoot the DLC circuit.

 

6.Test-drive the vehicle on a flat road in the D position. Check for abnormal noise and clutch slippage. While driving, check that the shift points occur at the proper speeds by monitoring the accelerator pedal position sensor voltage with the HDS and comparing your shift point speeds and voltage to those in the table. (The accelerator pedal position sensor voltage represents the throttle opening.)

Fully-opened throttle
Accelerator pedal position sensor voltage: 4.5 V 
Lock-up OFF 175-192 km/h (109-120 mph) 
4th®3rd 127-143 km/h (79-89 mph) 
3rd®2nd 85-96 km/h (53-60 mph) 
2nd®1st 42-50 km/h (26-31 mph) 

7.Drive the vehicle in 4th or 5th gear in the S position, then shift to 2nd gear by pressing the steering wheel downshift (-) switch. The vehicle should immediately begin to slow down from engine braking.

8.Shift to the R position, accelerate from a stop at full throttle, and check for abnormal noise and clutch slippage.

9.Park the vehicle on a slope (about 16 degrees), apply the brake, and shift into the P position. 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.
