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

Below short to ground limit value: There is (present) or was (not present) a short circuit to ground or an open circuit in the circuit to the control module pin.

Short circuit to B+: There is (present) or was (not present) a short circuit to voltage.

Checking Renewed check of fault memory - information after the ignition is switched off and subsequently switched on again. If the fault memory has been remedied, the text changes from present to not present

Total mileage Kilometer reading under which the fault has been saved

Vehicle speed The value indicates the vehicle speed at the time the fault occurred.

Version / vehicle parameters: Incorrect vehicle coding or coding not yet carried out.

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 100. The counter is decremented if the fault is no longer present. The fault memory is erased automatically when the counter reaches 0.
