Limit Switch & Pulse Switch
WARNING: This page is about a different car, the 2003 Lexus IS 300 and 2002 Lexus IS 300. However, it is still accessible from the selected car via links, so may be relevant.
Check that the master switch assembly automatic light flashes (for 45 seconds after the starter switch has been turned from ON to OFF with the driver's door opens) under the condition of KEY off operation.
- Limit Switch Malfunction - Even though the glass goes down from the fully closed position, the power window regulator switch assembly does not detect a change in limit switch signal within 2 seconds after the operation has started. See Fig 1.
- Pulse Sensor Malfunction - Even though the glass goes down from the fully closed position, the power window regulator switch assembly does not detect a change in pulse switch signal within 2 seconds after the operation has started.
