A/T Pressure Test

A/T Pressure Test









Removal

1. Vehicle Lift

1. Raise the vehicle on a lift, and make sure it is securely supported.

2. Warm Up The Engine

1. Start the engine. Hold the engine speed at 3,000 rpm without load in P or N until the radiator fan comes on.

2. Park the vehicle on level ground.

3. Turn the ignition switch to LOCK (0).

3. ATF Level Check





NOTE:
* Keep all foreign particles out of the transmission.
* Check the fluid level within 60-90 seconds after turning the engine off.
* Higher fluid level may be indicated if the radiator fan comes on twice or more.

1. Remove the ATF dipstick (yellow loop) (A), and wipe it with a clean cloth.

2. Insert the dipstick into the guide tube aligning the notch (B) with the guide tab (C).





3. Remove the dipstick, and check the ATF level. It should be between the upper mark (A) and the lower mark (B).

4. If the ATF level is below the lower mark, check for fluid leaks at the transmission, the hoses, and the line joints. If a problem is found, fix it before filling the transmission with ATF.

NOTE: If the vehicle is driven when the ATF level is below the lower mark, one or more of these symptoms may occur:
* Transmission damage.
* Vehicle does not move in any gear.
* Vehicle accelerates poorly, and engine rpm abnormally rises when starting off in forward and reverse positions.
* Engine vibrates at idle.

5. If the ATF level is above the upper mark, drain the ATF to proper level.

NOTE: If the vehicle is driven when the ATF level is above the upper mark, the vehicle may creep forward while in N, or have shifting problems.





6. If necessary, fill the transmission with ATF through the dipstick guide tube opening (A) to bring the fluid level between the upper mark and the lower mark of the dipstick. Do not fill the fluid above the upper mark. Always use ATF DW-1 (genuine Honda automatic transmission fluid). Using a non-Honda ATF can affect shift quality.

7. Insert the dipstick into the guide tube aligning the notch with the guide tab.

4. Front Splash Shield





1. Remove the bolts (A), then remove the clips (B) that secure the front inner fender and the front splash shield (C) to the body.

2. From under the front bumper (D), remove the clips (E).

3. From under the body, remove the clips (F), then pull out the front splash shield.

5. HDS DLC - Connection





1. Connect the HDS to the data link connector (DLC) (A) located under the driver's side of the dashboard.

2. Turn the ignition switch to ON (II).

3. Make sure the HDS communicates with the vehicle. If it does not communicate, go to the DLC circuit troubleshooting.

Test

NOTE:
* Check for DTCs. If any DTCs are stored, troubleshoot and clear them first.
* Do not allow dust or other foreign particles to enter the port while installing the A/T oil pressure gauge.
* Be sure to check the ATF level after each pressure port test. When installing or removing the A/T oil pressure gauge, ATF may run out of the pressure inspection ports.
* Disable the VSA by pressing the VSA OFF button.
* VSA DTC(s) may appear when running the wheels off the ground. If the VSA DTC(s) appears, clear the DTC (s) with the HDS after pressure testing.
