Abstract
A method for tracking defective functions in the operation of heater plugs in a diesel engine of a vehicle, provided with a control unit for the control of its heater plugs—the preheater control unit—, by monitoring at least one operating parameter of the heater plugs and/or of the preheater control unit, generating a fault message when the operation parameter so monitored deviates from a predefined nominal value or nominal state of the operating parameter, and storing the fault message. The invention links the fault message to a time parameter, stores the fault message together with the time parameter, searches for further fault messages that are stored in the vehicle and linked to the same time parameter, and combines the fault messages that are linked to the same time parameter.
