LUGGAGE COMPARTMENT DOOR OPENER SYSTEM Luggage Compartment Door Opener does not Operate

DESCRIPTION

The main body ECU (multiplex network body ECU) continuously receives the luggage compartment door opening cancel switch ON/OFF signal. When the luggage compartment door opening cancel switch signal is off, and the luggage compartment door opening switch is on, the luggage closer motor activates the luggage compartment door closer, and opens the luggage compartment door.
