A/T Pressure Test: 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.
