Fault handling II, emission-related misfiring or fault in fuel system
|
When fault criteria for closed loop, adaptation or emission-related misfiring are fulfilled and any dependents are OK, a diagnostic trouble code will be generated.
For the diagnostic trouble code to be cleared without any further measures being taken requires 1 driving cycle under similar operating conditions as when the fault first occurred or 80 driving cycles without the fault occurring again.
The CHECK ENGINE lamp goes on if the fault occurs again within 80 driving cycles.
For the CHECK ENGINE lamp to go out without further measures being taken requires 3 consecutive driving cycles under similar operating conditions as when the fault first occurred without the fault occurring again.
For the diagnostic trouble code to be cleared requires in addition 40 fault-free warming-up cycles.
