Official summary

This Prelimary information informs the dealer of a diagnotic trouble code that may set due to a failed high pressure fuel pump. Dealers are to check fuel pressure as per current testing outlined in GM service information and replace the fuel pump if needed.

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.
