The No. 1 power back door control switch signal is sent to the multiplex network door ECU.
If the power back door does not operate using the No. 1 power back door control switch, a No. 1 power back door control switch circuit malfunction is a possible cause.
If the multiplex network door ECU has been replaced, or if any of the connectors has been disconnected, initialize the power back door system.
Operate the multi-information display and check the customization status.
