Mode C:
Stop the introduction of negative pressure. (Wait until the tank pressure returns to the start level of P2 calculation.)
Change to Mode D when the tank pressure returns to the start level of P2 calculation.
Judge immediate OK and change to Mode E when it does not return in spite of spending the specified time.
TANK PRESSURE TIME
| Tank pressure when P2 calculation started | Time for immediate OK judgment | |

| 0.02-inch diagnosis | -3 kPa (-22.5 mmHg, -0.89 inHg) | 20 seconds |
