The operating signal on the electromagnetic valve of a purge of an adsorber is given through contact of C-E1 of the EBU socket under following conditions:

– temperature of cooling liquid is above 55 °C;

– air temperature is above 10 °C;

– the engine is not in the idling mode;

– the set threshold of loading is reached;

– the sensor of provision of a butterfly valve is not in situation "idling".

When performing diagnostics by means of "onboard system of diagnostics" the purge of an adsorber is not allowed.

Extent of cyclic opening of the electromagnetic valve of a purge of an absorber can be determined by the diagnostic unit by reading of the PR102 parameter (extent of cyclic opening of the electromagnetic valve of a purge of an absorber).

The electromagnetic valve is closed at the size of parameter below 1,2%.
