A/T Pressure Test






A/T Pressure Test









Removal

1. Warm Up The Engine

1. Warm up the engine.

2. ATF Level Check





1. Park the vehicle on the level ground.

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

3. Insert the dipstick into the dipstick hole.





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

5. 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 flares when starting off in forward and reverse positions.
* Engine vibrates at idle.

6. 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.





7. If necessary, fill the transmission with ATF through the dipstick hole (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 genuine Honda automatic transmission fluid (ATF) ATF DW-1. Using a non-Honda ATF can affect shift quality.

8. Insert the dipstick back into the dipstick hole.

3. Vehicle Lift

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

4. Engine Undercover





1. Remove the engine undercover (A).

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 come on during the test-drive. If the VSA DTC(s) come on, clear the DTC(s) after testing is done with the HDS.

1. 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.

2. A/T Line Pressure - Test

Line Pressure Test

1. Connect the A/T oil pressure gauge to the line pressure inspection port (A).






2. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on).

3. Run the vehicle in 2nd gear, and measure the low line pressure from the A/T oil pressure gauge while holding the engine speed at 2,000 rpm.

4. Bring the engine back to an idle, then apply the brake to stop the wheels from rotating.

5. Measure the normal line pressure while holding the engine speed at 2,000 rpm with the shift lever in P or N.

NOTE: When measuring the normal line pressure, do not measure with the shift lever in other than P or N.







6. If the line pressures are out of the service limit, refer to the problem and probable cause(s) listed in the table.







7. Turn the engine off, then disconnect the A/T oil pressure gauge from the line pressure inspection port.

8. Install the sealing bolt to the line pressure inspection port using a new sealing washer, and tighten the bolt to 18 Nm (1.8 kgfm, 13 lbfft).

NOTE: Do not reuse the old sealing washer.

3. A/T 2nd/3rd/5th Clutch Pressure - Test

2nd Clutch Pressure Test

1. Connect the A/T oil pressure gauge to the 2nd clutch pressure inspection port (A).






2. Start the engine, and run the vehicle in 2nd gear.

3. Measure the 2nd clutch pressure from the A/T oil pressure gauge while holding the engine speed at 2,000 rpm.







4. If the 2nd clutch pressure is out of the service limit, refer to the problem and probable cause(s) listed in the table.







5. Turn the engine off, then disconnect the A/T oil pressure gauge from the 2nd clutch pressure inspection port.

6. Install the sealing bolt to the 2nd clutch pressure inspection port using a new sealing washer, and tighten the bolt to 18 Nm (1.8 kgfm, 13 lbfft).

NOTE: Do not reuse the old sealing washer.

3rd Clutch Pressure Test

7. Connect the A/T oil pressure gauge to the 3rd clutch pressure inspection port (A).






8. Start the engine, and run the vehicle in 3rd gear.

9. Measure the 3rd clutch pressure from the A/T oil pressure gauge while holding the engine speed at 2,000 rpm.







10. If the 3rd clutch pressure is out of the service limit, refer to the problem and probable cause(s) listed in the table.







11. Turn the engine off, then disconnect the A/T oil pressure gauge from the 3rd clutch pressure inspection port.

12. Install the sealing bolt to the 3rd clutch pressure inspection port using a new sealing washer, and tighten the bolt to 18 Nm (1.8 kgfm, 13 lbfft).

NOTE: Do not reuse the old sealing washer.
