Pressure Test

Special Tools Required 

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 pressure gauge adapter.
  • Disable the VSA by pressing the VSA OFF button.
  • Be sure to check the ATF level after each pressure port test. When installing or removing the pressure gauge adapter, ATF may run out of the pressure inspection ports.
  • 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. Make sure the transmission fluid is filled to the proper level (see ATF LEVEL CHECK  ).
  2. With SH-AWD: Raise the vehicle on a lift, make sure it is securely supported, and allow all four wheels to rotate freely.

    Without SH-AWD: 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 front splash shield (see FRONT SPLASH SHIELD 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), or press the engine start/stop button to select the ON mode.
  6. Make sure the HDS communicates with the PCM, and go to the A/T Data List. If it does not, go to the DLC circuit troubleshooting (see DLC CIRCUIT TROUBLESHOOTING ).
  7. Connect the A/T pressure adapter to the A/T pressure test hose, then connect the A/T pressure test hose to the A/T oil pressure gauge set.
