DTC Code DTC Name
B2311 Power Window Motor Malfunction

DESCRIPTION

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

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

Tip:

This DTC may be stored for all the windows.

Note:

  • When the door window regulator 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 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 power window switch.
