Fault handling I, catalytic converter damaging misfiring
|
If catalytic converter damaging misfiring occurs, the driver will be warned immediately by the CHECK ENGINE lamp flashing at a rate of 1 Hz, irrespective of whether the lamp was already on or not. A diagnostic trouble code is generated at the same time.
For the CHECK ENGINE lamp to go out without any further measures being taken requires 3 consecutive driving cycles under similar operating conditions as when the fault first occurred without catalytic converter damaging misfiring occurring again.
For the diagnostic trouble code to be cleared requires in addition 40 fault-free warming-up cycles.
