Code B25B1 Description

The window motor contains a hall effect sensor to detect the window position. A hall effect sensor is a transducer that varies its output voltage in response to changes in magnetic field. If the motor loses its counts, it may perform erratically or in very short movements. The Diagnostic Trouble Code (DTC) sets when the Door Module senses the Window Hall Sensor Supply circuit is shorted to ground.
