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 all four wheels. Start the engine, then shift to [D] position while pressing the brake pedal. Press the accelerator pedal, and release it suddenly. The engine should not stall.

3.If the Honda PGM Tester is available, connect the Honda PGM Tester to the DLC, and go to the PGM-FI Data List, then go to 8. If the PGM Tester is not available, go to 4.

4.Remove the glove box stops, then bring the glove box down.

5.Loosen the mounting nut (A) on the lower portion of the PCM (B), and remove the mounting bolt (C) and nut (D).

NOTE: The illustration shows LHD model; RHD model is symmetrical.

 

6.Lift the PCM up to clear the mounting nut on the lower portion of the PCM, then pull out the PCM.

7.Connect a digital multitester (A) and tapered tip probe (B) to check voltage between the A15 (+) terminal and A23 (-) or A24 (-) terminal of the PCM.

 

 

8.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.)

Fully-opened throttle, throttle position sensor voltage: 4.5 V mph 93-106 90-99 
km/h 150-170 145-160 

9.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 slowing down from engine braking.

10.Accelerate from a stop at full throttle in [1] position. Check that there is no abnormal noise or slippage.Upshifts should not occur with the shift lever in this position.

11.Accelerate from a stop at full throttle in [2] position. Check that there is no abnormal noise or slippage.Upshifts and downshifts should not occur with the shift lever in this position.

12.Accelerate from a stop at full throttle in [R] position. Check that there is no abnormal noise or slippage.

13.Test in [P] (Parking) Position.
Park the vehicle on a slope (about 16°), apply the parking brake, and shift into [P] position. Release the brake; the vehicle should not move.
