All Power Windows do not Operate with Driver Side Door Key Cylinder or Wireless Transmitter: Description

When a transmitter switch is pushed: 1) the door control receiver receives the transmitter's signal, 2) the multiplex network master switch and multiplex network door ECUs receive the signal, and 3) the power window regulator motors are activated. When the driver door key cylinder is turned: 1) the door lock motor sends a signal to the front multiplex network door ECU LH (driver door ECU), and 2) the power window regulator motors are activated.

1. CHECK BASIC FUNCTION (WIRELESS DOOR LOCK CONTROL SYSTEM AND POWER DOOR LOCK CONTROL SYSTEM)
