2-inch Diagnosis
WARNING: This page is about a different variant/trim than selected.
MODE DESCRIPTION CHART
| Mode | Mode Description | Diagnosis Period |
|---|---|---|
| Mode A (0 point compensation) | When the pressure in the tank is not near 0 mmHg, wait until it returns to 0 point (near 0 mmHg). | 0 - Value of Map 1 |
| Mode B (Negative pressure introduced) | Decrease the pressure in the tank to the target value by introducing the intake manifold pressure to the fuel tank. | 0 - Value of Map 2 |
| Mode C (Negative pressure maintained) | Wait until the tank pressure returns to the target (start level of P2 calculation). | Value from Map 3 |
| Mode D (Negative pressure change calculated) | Calculate the time it takes for the tank pressure to change to the Mode E shifting pressure. If the tank pressure does not change to the Mode E shifting pressure, make advanced OK judgment. | 0 - 0 ms + Value from Map 4 |
| Mode E (Evaporation generated amount calculation) | Calculate the amount of evaporation (P1). | 0 - 0 ms + Value from Map 4 + Value from Map 5 |
