Toyota Venza: Auto Up Operation does not Fully Close Power Window (Jam Protection Function is Activated)

Toyota Venza Service Manual / Window / Glass / Power Window Control System / Auto Up Operation does not Fully Close Power Window (Jam Protection Function is Activated)

DESCRIPTION

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.

HINT:

This symptom may occur for any of the windows.

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.
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:
1. 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.
2. Open the power window by fully pushing down the power window regulator master switch assembly or power window regulator switch assembly.

PROCEDURE

1.	PERFORM INITIALIZATION (APPLICABLE LOCATION)

(a) Initialize the power window regulator motor assembly (applicable location) (See page ).

2.	CHECK POWER WINDOW CONTROL SYSTEM (AUTO UP/DOWN FUNCTION (APPLICABLE LOCATION))

(a) Check that all door power windows move when the auto up/down function of the power window regulator master switch assembly and power window regulator switch assembly (for front passenger, rear LH and rear RH sides) is operated (See page ).

OK:

Auto up/down function is normal (applicable location).

END (PROBLEM DUE TO INITIALIZATION FAILURE)

3.	CHECK WINDOW GLASS SLIDING MOVEMENT (APPLICABLE LOCATION)
