Remote Up / Down Function does not Operate: Description

When the power switch is ON (IG) and the window lock switch is set to UNLOCK, the multiplex network master switch sends remote signals to the multiplex network door ECUs, and the remote signals are sent to the power window regulator motors via the multiplex network switches. However, when the window lock switch is set to LOCK, the master switch sends window lock signals directly to each multiplex network switch.
