RM38N0EC _59 Vehicle Exterior _111831 DOOR / HATCH _0511871 FUEL LID OPENER SYSTEM J

DOOR / HATCH  FUEL LID OPENER SYSTEM  Fuel Lid Opener does not Operate  


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 NO. 1 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.
