  "textContent": "This invention refers to a method for diagnosing faults in the operation of a fuel heating system associated with an internal combustion engine, that includes a plurality of routines to detection of several kinds of faults. The relevant concern is to provide a sufficiently robust solution implemented by computer, to conceive a fuel heating system that includes a main control unit and a heating control unit independent from each other, both comprising respective “intelligences” so that this latter is particularly able to perform several functions and/or routines relating to the self-diagnostic of the heating system. For such, a method for self-diagnostic of fuel heating system that includes at least one engine control unit ECU that includes a respective microcontroller, and at least one heating control unit HCU that includes a respective microcontroller, both fed by at least one tension source interconnected to each other and to the at least heating element through an electronic circuit that still includes, at least, one main relay and at least one secondary relay",
