Pressure Test

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2015 Honda Crosstour, 2014 Honda Crosstour, 2013 Honda Crosstour, 2012 Honda Crosstour, and 2011 Honda Accord Crosstour. However, it is still accessible from the selected car via links, so may be relevant.

Special Tools Required 

NOTE:
  • Disable the VSA by pressing the VSA OFF button.
  • VSA DTC(s) may come on during the test-drive.
  • VSA DTC(s) come on, clear the DTC(s) after testing with the HDS.
  1. Make sure the transmission fluid is filled to the proper level (see ATF LEVEL CHECK  ).
  2. 4WD: Raise the vehicle on a lift, make sure it is securely supported, and allow all four wheels to rotate freely.

    2WD: Block the rear wheels and raise the front of the vehicle, make sure it is securely supported, and allow the front wheels to rotate freely, or raise the vehicle on a lift.

  3. Remove the engine cover (see ENGINE UNDERCOVER REPLACEMENT ).
  4. Connect the HDS to the DLC (A) located under the driver's side of the dashboard.

  5. Turn the ignition switch to ON (II).
  6. Make sure the HDS communicates with the PCM, and go to the A/T Data List. If it does not, go to DLC circuit troubleshooting (see DLC CIRCUIT TROUBLESHOOTING ).
  7. Connect the A/T oil pressure gauge to the line pressure inspection port (A), the 3rd clutch pressure port (B), and the 5th clutch pressure port (C). Do not allow dust or other foreign particles to enter the hole while connecting the A/T oil pressure gauge.

  8. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on).
  9. Measure the line pressure at the line pressure inspection port while holding the engine speed at 2, 000 rpm with the shift lever in P or N.
    NOTE: Higher pressures may be noticed if measurements are taken with the shift lever in any position other than P or N.
