INSPECTION PROCEDURE
Note
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.

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 operation at least 5 times:
Close the power window by fully pulling up the power window regulator switch assembly (for rear RH side) and holding it at the auto up position.
Open the power window by fully pushing down the power window regulator switch assembly (for rear RH side).
