Auto Up Operation Does Not Fully Close Power Window (Jam Protection Function Is Activated)

WINDSHIELD / WINDOWGLASS: POWER WINDOW CONTROL SYSTEM: Auto Up Operation does not Fully Close Power Window (Jam Protection Function is Activated)
- Auto Up Operation does not Fully Close Power Window (Jam Protection Function is Activated)

DESCRIPTION

The driver door power window regulator motor is activated by operating the power window regulator master switch. The driver door power window regulator motor has motor, regulator and ECU functions. DTC B2311 is set when the main body ECU determines that the driver door power window regulator motor malfunctions.

CAUTION:
* The power window control system uses a multiplex communication system (LIN). Inspect the communication function by following HOW TO PROCEED WITH TROUBLESHOOTING. Troubleshoot the power window control system after confirming that the communication system is functioning properly.
* When the power window regulator motor assembly (on the driver side) 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 resumed by repeating the following operation at least 5 times:
(1) Close the power window by fully pulling up the power window switch and holding it in the AUTO UP position.
(2) Open the power window by fully pushing down the switch.
HINT
If the pulse sensor in the power window regulator motor assembly (on the driver side) malfunctions, the power window control system enters fail-safe mode. The remote UP / DOWN and AUTO UP / DOWN functions cannot be operated during fail-safe mode. (However, the power window can be closed by holding the power window switch at the AUTO UP position, and opened manually by pushing down the switch.)
