The description below is presented twice since the fault counter behaves differently depending on what type of DTC that is being monitored. See the article Interpreting information in the Graph view for further information.
Unconfirmed DTC limit is +127
This data is accessed by clicking the left part of the timeline. The description below is applicable when the Unconfirmed limit and the Failed limit are the same i.e. +127. Please refer to the article Interpreting the Fault counter for further details about the Fault counter.

#1 - #5 in the figure represent control module operation cycles.
EOC in the figure is the abbreviation of control module operation cycle.
Unconfirmed DTC limit is less than +127
This data is accessed by clicking the left part of the timeline. The description below is applicable when the Unconfirmed limit is less than the Failed limit i.e. less than +127. Please refer to the article Interpreting the Fault counter for further details about the Fault counter.
