Initial Inspection and Diagnostic Overview

General information on the fault memory
Fault code setting conditions

Fault codes can be set in several circumstances, e.g.
- battery disconnected
- plug connections disconnected
- power failure
- etc.

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

Fault memory Info key [F8]

In order to be able to assess the fault exactly, the fault memory Info key [F8] must be pressed. This information should be saved using the Save key [F4] and printed out. If a fault code is stored with "not present" status and no other problems are present, then the fault memory must be erased.
