These figures mean the misfire ratio (%) in 400 ignitions; for example, 22.5 (%) means 400 (ignition) x 22.5 (%) = 90 (ignition) or more, so this case is judged misfire.
Time Needed for Diagnosis: 200 engine revs.
Malfunction Indicator Light Illumination: Illuminates as soon as the malfunction occurs.
