DESCRIPTION When the fuel
lid opener switch is pushed, a fuel lid opener switch signal is sent to
the ECM. The ECM turns on the FUEL OPN relay and EFI-MAIN relay, and the
fuel lid lock with motor assembly opens the fuel lid. When the fuel lid
is open, a fuel lid courtesy switch signal is output from the fuel lid
lock with motor assembly. WIRING DIAGRAM
