DTC B2311: Power Window Motor Malfunction: Description

The power window regulator motor is driven by operating the power window switch. The power window regulator sub-assembly consists of the motor, regulator and ECU.

This DTC is stored when the power window regulator motor has a malfunction, or the ECU built into the power window regulator motor determines that the fully closed window position has deviated approximately 20 mm (0.787 in.) or more from the normal position.

HINT: 

DTC B2311 is set when the ECU for the front door power window regulator motor assembly LH or RH malfunctions.

NOTE:
  • 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:
    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.
