- Notes
- Diagnosis frequency and MIL illumination: No refueling detected, leak > 1.0 mm
- Diagnosis frequency and MIL illumination: After refueling detected, leak > 0.5 mm
- Diagnosis frequency and MIL illumination: After refueling detected and no leak
- Diagnosis frequency and MIL illumination: After refueling is detected, filler cap left open
- Diagnosis frequency and MIL illumination: After refueling detected, "check filler cap" message ignored
