B2312
WINDOW / GLASS: POWER WINDOW CONTROL SYSTEM: B2312: Power Window Switch Malfunction
B2312 - Power Window Switch Malfunction
DESCRIPTION
The power window regulator motor consists of the motor, regulator and ECU. The power window regulator motor is driven by operating the power window switch.
This DTC is stored when the ECU built into the regulator motor determines that the power window switch is stuck.
HINT
This DTC may be stored 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:
(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.
