Auto Up Operation does not Fully Close Power Window (Jam Protection Function is Activated)
DESCRIPTION
If any door glass or a power window regulator motor 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.
HINT:
This symptom may occur for any of the windows.
INSPECTION PROCEDURE
HINT:
Since the power window control system has functions that use LIN communication, first confirm that there is no malfunction in the communication system by inspecting the LIN communication functions in accordance with the "How to Proceed with Troubleshooting" procedures. Then, conduct the following inspection procedure.
NOTICE:
When a power window regulator motor is reinstalled or replaced, the power window control system must be initialized.
After any 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 or power window regulator switch and holding it at the auto up position.
Open the power window by fully pushing down the multiplex network master switch or power window regulator switch.
