| Key-off Operation Function Operates even if Operating Conditions are not Satisfied |
DESCRIPTION
When the front doors are closed, each power window regulator motor assembly can control its power window operation for approximately 45 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 45 seconds have elapsed, or the driver door or front passenger door is opened within approximately 45 seconds of the power switch being turned off, the power window regulator motor assembly stops operating.
During an auto operation, when 45 seconds have passed and key-off operation is prohibited, the power window stops immediately.
CAUTION / NOTICE / HINT
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.
