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.
This symptom may occur for any of the windows.
The power window control system uses a multiplex communication system (LIN communication system). Inspect the communication function by following How to Proceed with Troubleshooting Click here. Troubleshoot the power window control system after confirming that the communication system is functioning properly.
When the power window regulator motor assembly is reinstalled or replaced, the power window control system must be initialized.
After a door glass or a door glass run has been replaced, the jam protection function may operate unexpectedly when the auto up function is used. In such cases, the auto up function can be reinitialized by repeating the following operations at least 5 times:
Close the power window by fully pulling up the multiplex network master switch assembly or power window regulator switch assembly and holding it at the auto up position.
Open the power window by fully pushing down the multiplex network master switch assembly or power window regulator switch assembly.
