DESCRIPTION
When the trunk and fuel switch assembly (fuel lid opener switch) is pushed, a fuel lid opener switch signal is sent to the ECM. The ECM turns on the FUEL LID OPN relay and the fuel lid with motor lock assembly opens the fuel lid. When the fuel lid is open, a fuel lid courtesy switch signal is output from the fuel lid with motor lock assembly.
