  • Publication number: 20110080176
    Abstract: It concerns a vehicle part comprising electric cables (4) adapted for conveying an electric current from at least one generator (2), with the said electric cables (4) that comprise at least one phase cable (40) associated with a phase of the generator, and comprising a short-circuit detection device (5) comprising measurement means (8) adapted for cooperating with the said phase cable (40). The electric cables further comprise a neutral cable (41), the detection device (5) comprising on the one hand the current measurement means (8), that are further adapted for cooperating with the said neutral cable (41), and on the other hand a control and calculations unit (9) connected to the said current measurement means and adapted for comparing with a determined threshold a value representative of the resultant of the currents circulating respectively in the said electric cables (4).

  • Patent number: 6626032
    Abstract: A method of diagnosing components used for leak detection in a closed vapor handling system of an automotive vehicle, implemented by a system, the method including providing leak detection components including a pressure switch that moves at a given relative vacuum, a control valve that operates to allow and prevent flow therethrough, and a shut off valve that operates to allow and prevent flow therethrough, running an engine, determining whether the pressure switch is closed, purging a canister, specifying a fail condition if the control valve is inoperative after purging, ascertaining whether the control valve is inoperative in a flow-through condition or inoperative in a non-flow-through condition if a fail condition is specified, specifying a pass condition if the control valve is functioning after purging, determining whether the shut off valve and pressure switch are malfunctioning if a pass condition is specified based on whether the pressure switch is open, and displaying an error if a component is ma
