Title: DOOR / HATCH: FUEL LID OPENER SYSTEM: Fuel Lid Opener does not Operate; 2019 - 2024 MY Camry HV [09/2018 - ]

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.
