FREEZE FRAME
Fault History has been divided into two categories, Freeze Frame and
Fault Seconds. Fault Seconds will record, in seconds, the length of
time an engine critical system fault occurred. All other faults will be
stored in a 10 buffer Freeze Frame. Freeze Frame allows the
technician to actually view what operating conditions the engine was
under at the time the fault occured.
The freeze frame auto capture software within the ECM, will store an
instantaneous snapshot of engine critical data that will give the service
technician more detailed information as to what the engine operating
conditions were like at the time a fault was logged. There are a total
of 10 storage buffers to retain fault information. The buffers are labeled
0–9 (10 buffer total). Each buffer will store a single fault. If frequent
faults occur with the same component, rather than storing the same
information in a new buffer, a frequency counter will be incremented
by one count and all the remaining data items will be updated at the
time the fault reoccurred. If there are no faults stored in freeze frame,
the DDT will display the following message: NO STORED FAULTS. As
the freeze frame buffers are filled, then the DDT menu choice will be
updated accordingly. Example: if there are 3 buffers filled containing
data, the DDT will display choices 0–2 in the menu list.
Make sure the SELECT FUNCTION menu screen is displayed on
the DDT.
