NOTE: The switch manufacturing date code may vary from the packaging date code due to a time delay between supplier manufacturing date and packaging date.

Inspect and remove all rocker switches from dealer parts stock that have a supplier manufacturing Date Code prior to 0844 on the switch, or a packaging date code prior to January 1, 2009 on packaging. The Date Code explanation is described after the switch part number listing.

Due to quantity of parts per part number, it is recommended that all part numbers are inspected in the following order, beginning with the first part number:
