POWER DOOR LOCK CONTROL SYSTEM All Doors LOCK/UNLOCK Functions do not Operate Via Door Control Switch or Door Key Cylinder

DESCRIPTION

The main body ECU (multiplex network body ECU) receives switch signals from the power window regulator master switch assembly, door control switch assembly, driver door key cylinder lock or unlock switch signals from the front door lock assembly RH*1 or front door lock assembly LH*2. The main body ECU (multiplex network body ECU) activates the door lock motor on each door according to these signals.
