Conditions:
- exhaust system - tightness of line = OK
- residual fuel volume in tank > X/X
- intake air temperature > XX°C
- pedal switch: brake pedal + clutch pedal = OK
- engine temperature = XX°C
- air-conditioning = OFF
Note:
The readiness Code must be created as the last diagnostics task. Later deletion of the memory could also result in deletion of the created readiness Code.
