WINDSHIELD / WINDOWGLASS: POWER WINDOW CONTROL SYSTEM: B2312: Power Window Switch Malfunction
B2312 - Power Window Switch Malfunction

DESCRIPTION

The power window regulator motor is operated by the power window switch. The power window regulator motor has motor, regulator and ECU functions.

This DTC is output when the ECU built into the regulator motor determines that the power window switch is stuck.

HINT
This DTC may occur for all the windows.

NOTICE:
* When the power window regulator motor 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:
* Close the power window by fully pulling up the power window switch and holding it in the AUTO UP position.
* Open the power window by fully pushing down the switch.
