| Title: DOOR / HATCH: FUEL LID OPENER SYSTEM (for HV Model): Fuel Lid Opener does not Operate; 2019 - 2022 MY Avalon HV [04/2018 - ] | ||
|
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.
