C-Chart Identification/Availability
The following table lists only those C-charts available for this engine, as well as their identifications.
The component system diagnostic charts (C-charts) are used when no trouble codes have been set but one or more of the scan data values are not within typical ranges. Also, many times these charts can be used as component or subsystem functional checks.
These charts are not contained in this article. They can be found in the appropriate article in the ENGINE PERFORMANCE section.
