POWER WINDOW CONTROL SYSTEM > Remote Up / Down Function does not Operate

for Preparation Click here


DESCRIPTION

  1. When the engine 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, but the window lock switch signal is sent to each switch via directly connecting lines.
