POWER WINDOW CONTROL SYSTEM, Diagnostic DTC:B2312

DTC Code DTC Name
B2312 Power Window Switch Malfunction

DESCRIPTION

The power window regulator motor assembly consists of the motor, regulator and ECU. The power window regulator motor assembly is driven by operating the power window regulator switch. This DTC is output when the ECU built into the regulator motor determines that the power window switch is stuck.

Tech Tips

This DTC may occur for all the windows.

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.
