DESCRIPTION
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.
CAUTION / NOTICE / HINT
NOTICE:
- The power window control system uses a multiplex communication system
(LIN communication system). Inspect the communication function by following
How to Proceed with Troubleshooting (See page

). 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.

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 power window regulator 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 power window regulator master switch assembly or power window regulator switch assembly.
