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
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.

Failed limit. |

Passed limit. |

Values of data parameters is sampled and stored each time the test is failed until the DTC has been confirmed. |
|
4 |
No more values of data parameters are sampled and stored after the DTC has been confirmed and prior erase of DTCs. |
#1 - #5 in the figure represent control module operation cycles.
Unconfirmed DTC limit is less than +127
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.
