Only Wireless Control Function is Inoperative [02/2019 - 08/2020]: Description

The door control receiver receives signals from the door control transmitter module set sub-assembly and sends these signals to the main body ECU (multiplex network body ECU). The main body ECU (multiplex network body ECU) then controls all doors by sending lock/unlock signals to each door, and sends hazard flasher signals to the combination meter assembly.
