Interpreting the Last to Now test result

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 green right 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.

Figure description (number 1-3)

Fig. No.	Description
1	Failed limit
2	Unconfirmed limit
3	Passed limit

Figure description (number 4-5)

Test result in number of control module operation cycles		Fault	Symptom	Fault tracing
Passed	No result
Test reached the Passed limit at least once but never the Failed limit. See fig. no. 4.	Test did not reach the Failed limit or the Passed limit. See fig. no. 5.
Low value High value	Low value	New Old	Most likely Least likely	Probably most easy Probably most difficult
Low value	High value	Unknown age	Unknown probability	Unknown probability

#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 green right 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.
