General Information on the Fault Memory

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

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.

Open circuit - short to ground / voltage short / version; vehicle parameters / counter

Fault type
The display shows which fault type has occurred:
- no fault type
- not present

Lock status of MOST ring
The display shows which fault type has occurred:
- lock
- unlock

Supply voltage
The value indicates the voltage at the time the fault occurred.

Fault counter
When a fault first occurs, a fault entry is made in the fault memory and the counter is simultaneously set to 50.

If a fault is present, the counter is incremented by 1 for each "ignition on". The maximum count is 255.

The counter is decremented if the fault is no longer present. The fault memory is automatically erased when the counter reaches 0. If the error occurs again when the counter is between 1 and 49, the counter is reset to 50.
