Road Test

Special Tools Required 

Backprobe set 07SAZ-001000A (Two required)

  1. Warm up the engine to normal operating temperature (the radiator fan comes on).
  2. Apply the parking brake, and block both rear wheels. 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.
  3. Repeat the same test in the D3 position.
  4. Connect the HDS to the DLC (A), and go to the A/T data list; then go to step  6. If you don't have a HDS, go to step 5.

  5. Remove the dashboard lower cover (A) under the glove box (B) to expose the PCM connectors (C).

  6. Connect a digital multimeter (A) and the special tools (B) to check voltage between PCM connector terminals A15 (+) and A24 (-) (2002-2004 models), A29 (+) and A9 (-) (2005-2006 models).

  7. 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 throttle position sensor voltage and comparing your shift point speeds and voltage to those in the table. (The throttle position sensor voltage represents the throttle opening.)

  8. Accelerate to about 35 mph (57 km/h) so the transmission is in 4th gear, then shift to 2nd gear. The vehicle should immediately begin slow down from engine braking.
  9. Check for abnormal noise and clutch slippage in the R position. Accelerate from a stop at full throttle, and check for abnormal noise and clutch slippage.
  10. Test in the P (Parking) Position.

    Park the vehicle on aslope (about 16°), 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.
