## NHTSA's summary

Service Bulletin for Front Lighting Ground Splice Pack Failure. The left and right hood lighting of these vehicles have separate ground paths to the frame and use the same splice pack parts. The splice packs are part of the hood commodity and located near the headlight assemblies. These splice packs can fail, resulting in either the left or right lighting becoming intermittent or inoperative.
