A/T Pressure Test

A/T Pressure Test

Special Tools Required

- A/T Oil Pressure Gauge Set 07406-0020400 or 07406-0020401
- A/T Pressure Test Hose 07AAJ-PY4A100
- A/T Pressure Adapter 07MAJ-PY40120

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.
