HINT
If the pulse sensor built into the power window regulator motor assembly (for rear RH door) malfunctions, the power window control system enters fail-safe mode. The remote up and down and auto up and down functions cannot be operated during fail-safe mode. However, the power window can be closed by holding the rear power window regulator switch assembly (for RH door) at the auto up position, and opened manually by pushing down the rear power window regulator switch assembly (for RH door).
Scheme 316
- When the front doors are closed, each power window regulator motor assembly can control its power window operation for approximately 43 seconds after the power switch is turned from on (IG) to off by receiving operation permission signals from the main body ECU (multiplex network body ECU).
- However, when approximately 43 seconds have elapsed, or the driver door or front passenger door is opened within approximately 43 seconds of the power switch being turned off, the power window regulator motor assembly stops operating.
- 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.
