8.2.8.1 The Event Recorder Window
The previous steps will cause the AE300-Wizard to read in and interpret the selected event
recorder hex dump file and to open a new window displaying the result (combining data
from both ECUs):
-
Per default the events are sorted by their timestamp (the left most column)
-
The data displayed can be sorted in ascending or descending order by clicking on the
columns headers (e.g. clicking on the DTC header will sort all events by their DTCs)
-
A red background marks the “beginning” of an event (i.e. “Rail pressure below normal
range”)
-
A green background marks the “end” of event (i.e. the event “Rail pressure below nor-
mal range” has ended and the rail pressure is back to normal now)
Example:
Interpretation:
-
April 15 th , 2009 at 8:37:39 (DTC=1E34, event status=00000001, event count=122h)
-
DTC 1E34 is a “rail pressure operating range” event of the type MIN. The code is auto-
matically translated into the textual description “Rail pressure below normal range”
-
The event status (see layout in appendix “12.3.1 Event Status”) is automatically trans-
lated into “beginning of an event” (i.e. the rail pressure fell below a predefined limit)
and it was recorded at ECU-B which was also the active ECU at that time
-
This was event queue entry 290 decimal (122 hex)
-
April 15 th , 2009 at 8:37:39 (DTC=1E34, event status=00000000, event count=123)
-
Active ECU B recorded (as entry number 291dec/123hex) the end of the event “rail
pressure below normal range” (rail pressure increased again above a predefined limit)
-
The timestamp resolution is 1 second, so this was a very short pressure fluctuation
-
The two lines above show, that the passive ECU A detected and recorded the same rail
pressure fluctuation about 1 to 2 seconds later.
