Fault setting condition(s) (See [Information])
- Diagnosis detects uneven running for the specified cylinder.
- Uneven running is calculated from the expected and actual crankshaft acceleration due to combustion.
- Uneven running is interpreted as a misfire or valve lift fault, depending on type.
INFORMATION
- It is possible that only one cylinder (or the cylinders of one bank) has/have exceeded the uneven running threshold for a fault entry.
- Other cylinders may be just below the level which would result in a fault entry.
- See Actual values:
- [M005_Rough running ...] ... [M080_Rough running ...]
