When the engine is running or the ignition switch is ON, the front power window regulator motor assembly LH is operated by the multiplex network master switch assembly. The front power window regulator motor assembly LH has motor, regulator, and ECU functions.

HINT

If the pulse sensor built into the front power window regulator motor assembly LH malfunctions, the power window control system enters fail-safe mode. The remote up/down and auto up/down functions cannot be operated during fail-safe mode. However, the power window can be closed by holding the multiplex network master switch assembly at the auto up position, and opened manually by pushing down the multiplex network master switch assembly.

  1. When the front doors are closed, each power window regulator motor assembly can control its power window operation for approximately 43 seconds after the ignition switch is turned from ON to off by receiving operation permission signals from the main body ECU.
  2. However, when approximately 43 seconds have elapsed, or the driver side door or front passenger side door is opened within approximately 43 seconds of the ignition switch being turned off, the power window regulator motor assembly stops operating.
  3. During an auto operation, when 43 seconds have passed and key-off operation is prohibited, the window operation stops immediately.

If a door glass or a power window regulator motor assembly does not operate smoothly, the jam protection function may be triggered automatically, resulting in the auto up function being unable to fully close the window.

HINT

This symptom may occur for any of the windows.

This symptom may occur for any of the windows.

The jam protection function operates within a specified range during the manual up or auto up operation.

The power quarter windows are operated by power quarter window switch on the instrument panel while the ignition switch is in the ON position.
