FLUSH HANDLE SYSTEM Only the Front Passenger Side Flush Handle Extension or Retraction Operation does not Operate

DESCRIPTION

The signals of each switch from inside the door outside handle sub-assembly RH*1 or door outside handle sub-assembly LH*2 in the driver side flush handle are sent to the main body ECU (multiplex network body ECU) through the front multiplex network door ECU RH*1 or front multiplex network door ECU LH*2. The main body ECU (multiplex network body ECU) performs operation judgment based on input signals and sends operation request signals to the front multiplex network door ECU RH*1 or front multiplex network door ECU LH*2.
