Notes on reading out the diagnostic fault code memory

Reading out the diagnostic fault code memory:

 If a malfunction occurs during the teach-in process, the EHZ control unit outputs a corresponding flash code via the EHZ indicator lamp.

1 Display the fault codes stored in the EHZ control unit.
The EHZ indicator lampin the instrument now flashes once or several times, according to the fault codes which have been stored.
The display of the fault code is followed by a pause of
approximately 5 s (EHZ indicator lamp off), after which the fault is displayed once again (endless loop).

 Following the rectification of the malfunction, the teach-in process must be restarted and carried out completely.

If necessary, the teach-in process must be repeated until no further malfunction occurs.
