Official summary

Various other DTCs may be set. This may be due to engine harness chaffing at the right cylinder head near connector C1056 at the cylinder head core plug boss. The connector will need to be removed from the retainer to inspect the back side of the harness for any damage. Repair as necessary. Make sure to wrap the exposed wiring with Rotunda Co

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
