|
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 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.
