INSPECTION PROCEDURE
- NOTICE:
- 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 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 switch.
- 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.
