DTC B3225
CIRCUIT DESCRIPTION
The driver door module (DDM) and passenger door module (PDM) check for hall sensor pulses and relay feedback of their respective window motors at least once every 50 milliseconds. When the DDM or PDM detects no hall sensor pulses or relay feedback in the window motor, a DTC is set. For more detailed information concerning power window operation, refer to Power Windows Description and Operation.
