Abstract
In a method for localizing a fault location within a fuel injection system, when a critical fault is detected by the diagnostic function, a pulse or a series of pulses to the injectors is triggered by a control unit. By observing the voltage value and/or charge value at the injector, it is possible to localize the fault location within the fuel injection system.
