Key-off Operation Function Operates even if Operating Conditions are not Satisfied: Description
When the driver door has not been opened and fully closed, each door power window regulator motor can control its power window operation for approximately 45 seconds after the ignition switch is turned from ON to OFF (the key is removed) by receiving operation permission signals from the main body ECU. However, when approximately 45 seconds have elapsed, or the driver door or front passenger side door is opened within approximately 45 seconds of the ignition switch being turned OFF (the key is removed), the power window regulator motor stops operating.
NOTE:
- The power window control system uses a multiplex communication system (LIN). Inspect the communication function by following HOW TO PROCEED WITH TROUBLESHOOTING. Troubleshoot the power window control system after confirming that the communication system is functioning properly.
- The power window control system prohibits the AUTO UP / DOWN function when the jam protection function malfunctions. Therefore, troubleshoot the power window control system after confirming that no diagnostic codes are displayed.
