i) System diagnostics
With the self-test program integrated in the EDS control unit, the "electronic diesel system" can be checked and faults recorded and stored.

Temporary faults of more than 4 seconds duration are also memorized.

E.g. sensor faults with the exception of speed sensors are memorized, as well as short-circuits in the actuators or their lines.

The pulse display can be tapped via the test connector (X11/4), socket 4 and the individual faults evaluated with the aid of a pulse counter. Depending on the readout, the defective component or its leads can be determined.
