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 (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 ignition 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 power window stops immediately.
The power window control system uses the LIN communication system. 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.
If a power window regulator motor assembly has been replaced with a new one, initialize the power window control system.
If the main body ECU (multiplex network body ECU) is replaced, refer to Service Bulletin.
Check that the manual up and down function using the multiplex network master switch assembly and power window regulator switch assembly can operate the power windows.
Manual up and down function is normal.
