General Information on the Fault Memory

Fault code setting conditions

Fault codes can be set in several circumstances, e.g.:
- Power failure
- Plug connections disconnected

In these circumstances, no fault is present in the system and the fault memory must be erased.


Fault Memory Info Key F8

The Info key F8 has no function in the "Seat memory" system. The additional information appears together with the fault code and the fault text, e.g. "8 Hall-effect sensor, fore-and-aft adjustment open circuit present". The fault memory content is updated (changes from present to not present) only when the switch for the memory seat adjustment or the switch for seat adjustment is actuated.
