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.
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.
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.
