The chart above describes the case where refueling is detected, the filler cap is left open and the "check filler cap" message is ignored by the driver. While driving the "check filler cap" message will illuminate in the panel immediately after a leak diagnostic is performed. During soak, another leak diagnostic is performed.

The MIL will be illuminated after an additional two driving cycles.
