Fault handling, (II) fuel system, emission-related misfiring
|
When fault criteria for closed loop, adaptation or emission-related misfiring are fulfilled, a diagnostic trouble code will be generated. A special code will also be generated if the fuel level in the tank is below 10 litres to facilitate fault diagnosis.
To clear the diagnostic trouble code and low fuel level code, if generated, without having to take any further measures requires 1 driving cycle under similar operating conditions as when the fault first occurred or 80 driving cycles without the fault recurring.
The CHECK ENGINE lamp will go on if the fault reoccurs within 80 driving cycles.
For the CHECK ENGINE lamp to go out without any further measures being taken requires 3 consecutive driving cycles under similar operating condition as when the fault first occurred without the fault recurring.
For the diagnostic trouble code and the low fuel level code, if generated, to be cleared requires a further 40 fault-free warming-up cycles.
