Power window main switch and front power window switch (passenger side) monitors the power window motor operation and the power window position (full closed or other) for driver side and passenger side power window by the signals from encoder and limit switch in front power window motor (driver side and passenger side).

When power window main switch detects interruption during the following close operation

  1. automatic close operation when ignition switch is in the "ON" position
  2. automatic close operation during retained power operation
  3. manual close operation during retained power operation

power window main switch or front power window switch (passenger side) controls each power window motor for open and the power window will be lowered about 150 mm (5.91 in).

Power window main switch and each power window switch monitors the power window motor operation and the power window position (full closed or other) for each power window by the signals from encoder and limit switch in power window motor.

When power window switch detects interruption during the following close operation

  1. automatic close operation when ignition switch is in the "ON" position
  2. automatic close operation during retained power operation
  3. manual close operation during retained power operation

Power window main switch or each power window switch controls each power window motor for open and the power window will be lowered about 150 mm (5.91 in).

POWER WINDOW CONTROL BY THE KEY CYLINDER SWITCH

When ignition key switch is OFF, front power window can be opened or closed by turning the key cylinder switch UNLOCK/LOCK position more than 1.5 second over condition.

  1. Power window can be opened as the door key cylinder is kept fully turning to the UNLOCK position.
  2. Power window can be closed as the door key cylinder is kept fully turning to the LOCK position.
