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 parking brake, and block rear wheels securely.
3. Start the engine, then shift to the D position while depressing the brake pedal. Depress the accelerator pedal, and release it suddenly. Make sure that the engine should not stall.
4. Repeat the same test in the D3, 2, and 1 position.
5. Connect the HDS to the DLC (A), and go to the PGM-FI data list; then go to step 10. If you don't have a HDS, go to step 6.

6. Pull back the carpet, and remove the passenger's and driver's side center lower covers to expose the PCM (see HOW TO REMOVE THE PCM FOR TESTING ).
7. Remove the PCM cover from the passenger's side under-dash to access the PCM mounting nut.
8. Remove the PCM mounting bolt, then remove the PCM (A).
9. Connect a digital multimeter (B) and the special tools (C) to check voltage between PCM connector terminals C27 and B20 or B22.

10. 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.)

11. Accelerate to about 35 MPH (57 km/h) so the transmission is in 4th or 5th, then shift from the D position to the 2 position. The vehicle should immediately begin slowing down from engine braking.
12. Check for abnormal noise and clutch slippage in the following positions:
    • 1 (1st Gear) Position  - Accelerate from a stop at full throttle. Check that there is no abnormal noise or clutch slippage. Upshifts should not occur with the shift lever in this position.
    • 2 (2nd Gear) Position  - Accelerate from a stop at full throttle. Check that there is no abnormal noise or clutch slippage. Upshifts and downshifts should not occur with the shift lever in this position.
    • R (Reverse) Position  - Accelerate from a stop at full throttle, and check for abnormal noise and clutch slippage.
13. Test in P (Park) Position. Park the vehicle on a slope (about 16°), apply the brake, and shift into the P position. Release the brake; the vehicle should not move.
